Sam Can't Come to the Blog Right Now

Greetings all. With one week to go before Oshkosh, figured I would provide you all with a little update, and as the title alludes to, Sam is busy working long days and late nights in the shop on the Prototype to get her done before AirVenture. We have made terrific progress the past few weeks. The plane is looking more and more like a flyable airframe. We have had one of the wettest and most humid Junes and Julys in recent memory, which has made painting a meteorological endeavor. Over the last few weeks we have finished laying up all of the composite and aluminum fairings; however, finding a clear day with low humidity (and no pollen) to paint has proven a challenge. Luckily we have had a few good days the past week and this weekend we were able to actually put the finishing touches all on the Hawk.

Another huge win since the last post was that we got in our prop! It looks great and and fits perfectly after Scott did some fine machining on the hub. The best part of a torque-y Verner radial is you can swing a [relatively] big prop. Between finishing the painting, the fairings, and the prop, the P-36 has some huge ramp appeal, despite its diminutive side.

Personally, I buttoned up the last of the electrical this week and ran some conductivity tests and everything seems in good order to run a start up test. I have also taught myself to use my wife’s Cricut to cut some of the smaller vinyl decals now that we have finished painting. Scott has been working on finalizing the mounting design of, and finishing the construction of, the nose cowling. The cowling has been a challenge as the complex geometry and various materials means it is only one part design and two parts artistry. Sam has been very patient with all of us as he has been teaching us everything from laying up fiberglass to match cutting tubing. The learning process on making this cowl will definitely go a long way towards us being able to provide a nearly finished and ready to install cowl on future kits; saving all of you the toil. Trevor and I finished the underside of the airplane and riveting the fairings on the wings, while Gary finished up the horizontal. Sam in all of this has been doing everything. I’m only writing this at midnight on a work night because when I left the shop an hour ago, he was just starting a new part for mounting the cowling, and I highly doubt he will get to this Blog when he is done.

The plan for this week is to finish the whole plane (easy, right?). We want to get it ready to show off at Oshkosh and be ready to start our test program in the weeks following. While we were hoping to be flying before the airshow, we still feel confident that we will be able to bring you a finished aircraft, even if it hasn’t flown yet. Still up for this week: finish the graphics, install the audio panel, attach the ailerons, finish, mount the cowling, and connect all of the thingamajigs to the whatchamacallits. All in all, not a horrible place to be after our last full week of work.

Feel free to share your love and support in the comments below, and if you will be at AirVenture be sure to stop by and check us out in the Homebuilt area.

Count-down!

Shame on me, I have not been keeping up with the blog. We are sprinting to Oshkosh with much to do yet. It is important to keep all of you up to speed on the project and plans. Aaron has updated our website recently and I hope you enjoy it. I’m getting good reviews/comments. There is a lot of content we will be adding as time allows us. I understand that we are a little shy on the project info. Will be addressed!

Sun N Fun was better than we thought it would be. I would guess about 70% of the crowd and vendors were there. They are saying record crowd on Saturday. I would agree. We did not bring the P-36 as it was too close to being done to take it apart and risk the road rash, and too far from done to really show it off. So we went with the Verner Motor only booth setup. We still had at least 8 customers who stopped in specifically to see the P-36. Many more were interested when they found out about it. Verner engine interest was strong and as good as any year we’ve been.

Project update: we have installed the new engine, it’s systems and are finishing up the electrical and avionics systems. Aaron is putting his robotics build experience to the test with the wiring. Doing great! We have installed the aileron controls in the center-section of the wing. The control stick had too much side to side play. We fixed that with milling out the welded-in tube and welding in a new, larger tube that uses flanged bushings. We also 3D printed an Army style stick grip and are installing it onto the control stick. Looks and feels great! We added the radio, transponder, ELT and electrical switches, breakers and ignition system controls onto a new panel, beneath the instrument panel. Very much like a P-40 has - the P-36 had it’s switches on the side panels and that is not good for in-advertent bumping with your leg. We had the leg room to spare with the panel so there it went. We will add an arm rest for the throttle on the left side and a COM box and panel on the right side of the cockpit.

Along with the switch and radios panel, we have run all of the antenna, trim and lighting wiring and installed the components. We also ran the engine sensors and ignition wiring, voltage regulator, battery, solenoid, buses, wired up the panel and gauges too. Big job! Not as big as some of you folks do with the RV’s and fast glass for sure. We installed the fuel lines to the carburetor, installed the fire-proof poke-thru’s in the stainless firewall. Ran the oil hoses, cooler, separator and breather line too. We are right at the point of closing up the belly of the aircraft for the last time and finishing the fairings along the bottom of the wings. We are also about to tackle the cowling and it’s support frame - as well as the cowl flaps. The three blade ground adjustable prop is ordered and we are holding our breath it gets done in time. They are promising it will be here on time, so it will be a nail-biter! We went with NR Prop in Ukraine. Good things are being said and they have the right shape and diameter. For direct-drive, higher hp engines, they make the blade of carbon fiber. Our backup is the Warp Drive which is excellent - it’s just not the WW2 shape. Rounding the tips helps though. We may buy one to be sure to have a prop at AirVenture 2021 and to compare in-flight performance after the show. Still deciding on that, but time is running out.

We are currently working the throttle and choke cable connections, painting the smaller components and panels, and completing the 3D modeling of the cowling and sub-frame with the latest thinking. Our welder is catching up on engine mounts and exhausts for our customers and will jump on our exhaust right away for the show. I am hoping to have the cowl, cowl flaps, wing root fairings and tail fairings ready to paint by 4th of July. Decals and paint stencils after that. The count-down is on to Oshkosh! Our crew is on it!

The Twist

Spring is trying to break through here in the Northeast, but not quite able to shake that winter chill. April just arrived and we have been working all of March on prepping for a new engine. Foremost was dealing with our landing gear. The third time I believe. This time, we had a nagging toe-in twist when the full weight of the aircraft was put to them. Studying it carefully, it was a combination of two things. The teflon liners inside the main tube had been relieved to allow the gear to easily slide with the spring motion. Well, we had given it too much clearance and that allowed the whole lower leg to pivot off center slightly. That little amount of sloppiness exacerbated the little bit of miss-alignment that I had welded-in on the scissor-links. Allowing the wheels to still toe-in a little bit. Barely noticable, but I don’t like it. One side slightly more than the other as well. Dang it!

After removing the engine to crate it for shipping to it’s new owner, we put the A frame back onto the engine mount and removed the landing gear. Scott studied the issue with the sleeves and ordered new teflon tubes. They arrived and were undersized on the ID. He then created a special reamer to take out the .010” all-around needed for the lower leg shaft to slide inside smoothly with no binding. The front of the reamer is the same as the id on the existing tube. Then he tapered out to the final ID we want and added cutting flutes. It worked, but clogged with chips quickly. Modifying this to allow the chips to exit also messed up the surface finish. Made a second reamer more like the original but shorter. This did a great job. It did take some time and careful drill work. We are just about done with the landing gear - again. We will be doing some careful milling and drilling of the scissor link upper mounting lugs to get them to track the wheels better. A little milling, a little paint, makes her what she aint. I am planning to get that done this first weekend in April in order to be able to put the gear back on and remove the A frame.

At the same time of working on the landing gear, we have been fabricating the fuel pumps panel assembly and installing it and the rest of the fuel hoses and tubing in the fuselage. It is 99% complete from firewall to the fuel tanks. Just one little thing left - adding the low point drain. That will be doable after we get the landing gear on and install the bottom skin and tunnel. Then, I can work from above the seat and below. Its a sequence thing.

Also have been working on the electrical system. Installing wiring and loom for fuel senders, landing and navigation lights. Made plywood mounting panel for the battery, solenoids and terminal blocks. They will fit up in the gun deck between the machine guns and on top of the forward fuselage frame bracing. I am finishing up the electrical schematic to know just how many switches and circuit breakers we will need a home for.

One more thing we have been working on is the tail and wing fairings. We had Jack Charles of Madison, WI English wheel our fairings for us. He was eager to try it - being a metal smith shop teacher for a high school and technical college. We sent him templates and descriptions of how much to roll and where. They came out very well. Excellent for only written descriptions and images. That is a tough thing to do and he did great! I trimmed and located the fiberglass trailing edge of the wing root fairings, drilling them when just where I wanted them. That plastic exterior painters tape did great for holding everything in place. The sheet metal fairing panels were then taped into location and adjusted as necessary. When good, I drilled and cleco’ed them to the wing and fuselage.

I used what seemed like a bunch of clecos to do it. I was kind of disgusted with my work thinking I had too tight of hole spacing, until I looked back at the reference photos. Curtiss had done the same thing on the real P-36. Lots of screws in the fairings and so ours looks right after-all. Back when we made the large trailing edge fiberglass pieces, we had made small fiberglass fairings for the leading edge of the wing where it gets seriously compound and tight. These were not the right shape after installing the sheetmetal fairing panels. The leading edge of the tail surfaces is another very tricky spot and we did not make a fiberglass piece for that. Thought about it long and hard and I want to try to pound out a soft annealed sheet metal leading edge. Ordered plenty of soft sheet and am about to get on that project. Getting those pieces done will allow me to finish the bottom section of the wing root fairings. Shouldn’t take too long. Adding the wing root fairings makes it look so much better! I can’t wait to paint them and see it with the wings and cowl.

Oh yah, Rob Walty made us our four quadrant cowling side panels and the nose bowl. We will be ready to start working on the cowl shortly. April and May will be really fun work!

We will be at Sun N Fun 2021 in a couple weeks. Our booth is in front of Building A and B along the main thoroughfare. Look up N68 on the exhibitor map. Sorry, we will not have the plane there. Way too close to flying to dismantle it and risk the trailer rash of hauling it both ways. We will have a brand new Verner Motor 9S radial engine on display. Our customer for that engine, Bob Beaty is #2 at the Sun ‘n Fun organization. He twisted my arm to have it on display. So after not planning to attend, we will. If you are going, please stop by and say hello. Love to talk with you. Then, right back to work right after we get back.

The Weighty Decision

Hey, since the end of January, we have been working up to where we are now. hahahaa! Of course! The landing gear was done and it was time to focus on systems. Such as the fuel system, electrical, oil, lights, etc. We installed the main fuel line in the fuselage from the selector valve to the firewall. Fabricated the selector valve mounting bracket and painted it. Made steel plugs for the firewall engine mounts to fireproof them as they pass behind the firewall. This allowed us to install the engine mount. We added the major components to the firewall as well (Ignition system, voltage regulator, air/oil separator, oil tank, the structural “tunnel”). We then decided to go ahead and mount the engine. We had to fabricate four spacers to move the engine 1/2” forward due to an error in the engine mount design which put one mounting puck support too close to an intake tube. This worked fine and we bolted the engine in place. Now we can look at the throttle installation and were all the systems and cables will route up forward. We had a cowling nose bowl that Rob Walty made for us and we had to fit it on the front. The sight lines are awesome!

Then, someone asked: “how much does it weight?” Well, that got us thinking, we really should do an in-progress weight and balance before we install everything - in case we need to move stuff. Well the wings were at the hangar and with the weather interfering, we needed to pick a good day to move the wings to the shop. We finally got a chance and brought them to the shop unscathed. Didn’t take us long to say - “ok, lets pin them on and see what she looks like”. Well they fit almost perfectly, but not quite. They had been assembled on the bench at the home shop, but we had replaced the inboard to outboard attachment brackets with more robust ones. Well, the more robust ones were a smidge too long and the inboard holes didn’t match the outbd holes. Scott spent a few hours filing the new brackets down to where the wings will fit together as intended. So we pinned the outboard wing panels onto the inboard ones and DANG! Looks like a fighter plane! We had finally achieved another milestone! We still need to drill and ream the holes to install the final bolts, but we have some other work to do first.

Back to the weight and balance, we did a relatively quick weighing of the plane on our bathroom scales. The weight seemed really good, 50 lbs under our target, but the balance was way off towards the tail. The whole thing felt fishy. Did some head scratching for a night or two, we then ordered better ‘industrial’ scales off of Amazon. Well as industrial as they can be for $40 each (They aren’t bad!) Importantly though, they have a digital readout display on a cable separate from the scale pad itself. We decided to try again with the hopefully more accurate scales. These new numbers showed us 90 pounds over our goal and still tail heavy. 90 pounds??? Turns out while bathroom scales can handle a decent amount of weight, they are designed to handle that from two feet standing on either side of the scale. Put all the weight in the middle and the plastic flexes… and bottoms out. Thus I can go on a serious 30lb diet just by changing my posture to a Flamingo stance! Jeeze, I thought that they may be cheap, but would only be off maybe 10 pounds or so. Nope! BEWARE! Even the new ‘Industrial’ scales showed a bit of flex from too much of a point load, so we decided to try and spread that more evenly on the scales.

So with some thick aluminum plates to distribute the load from the wheels, we rolled the plane onto the industrial scales: and at this point it was showing with the current engine, wings, structure, and all of that we are 775 pounds empty, with an aft CG which will only work with the lightest pilots. Ok, well we knew we were not building light and lean. We did not optimize this first-article’s structure for weight. This is a prototype and we know we can loose about 20-30 pounds with some design refinements, but we’ll definitely have to make sure to focus on that tail area next time. However, we also have been planning to at some point swap the engine for the heavier 7 cylinder Verner, or in-line auto conversions, such as the AeroMomentum AM15. Looks like now is a good time to do that!

The good news! The calculations show that with the Verner 7U or the AM15, or Viking 130, or basically any engine in the 200lb range, our empty center of gravity will be at 16% of our mean cord, with a total weight of approx. 829 pounds. A light pilot and low fuel is 22% cord and heavy pilot, full fuel and bags is 26% cord. A little heavier than planned (as is tradition it seems) but just about on par with published numbers for the RV-3, Panther, Onex, WAR Corsair and others, in terms of wing area, empty weight and hp. Each is a little different and we fit right in the middle of the lot. All told, we should have excellent performance!

So, which engine? We have been agonizing this bit over that for two weeks and they all have pluses and minuses for our project. We love radials! The 7U is an awesome engine with power and sound that just grabs everyone’s attention. We will be first to admit they can be a bit pricey. The AM15 is an excellent deal for price and power. Mark and the whole company are awesome to work with and they know their stuff. Most of our initial customers are going to want the P-40 model and we need to develop the firewall forward for it anyway. Sure, the reduction drive propeller shaft sits fairly low on the engine, and turns the “wrong” way; but that would still work for the early model P-40s (A, B, C) which is what this prototype is set up to be anyway. I have a lot of VW engine time so I and others like me are used to the p-factor being “wrong”. Then certainly it looks like the Viking 130 or even the new 150 would be options for the P-40E models and should have the power to make this aircraft perform. There seems to be plenty of options there. Some of the exhaust stuff on the P40 is going to be a bit of a tetris challenge to tackle, with getting the exits to all work. Radials aren’t immune to that either of course.

Of course, at the end of the day there was one obvious answer, and the only question was whether it could happen in time. We all want to see the P-36 fly, so we’re going to stick with the radial and get it flying as fast as possible. With our relationship with Verner, and the joy it would bring all to see our plane fly with a 7 cylinder on the nose, we talked with them and found a way to get a 7U within our timeframe. A toast for those guys for the effort they put into all of the engines and for taking care of us.

Of course, we need to still do a P-40 before there’s a riot; so the plan remains that we will do that, and use the auto engines for the next production prototype. On the next fuselage it will be a P-40E type, and will have all the improvements and lessons learned from the first go; including the retracts and a few other great adjustments to the lines. This version we will build concurrently with our early builders. And of course, for any P-40, we need to develop the engine mount, the exhaust headers, the radiator installation, the plumbing and cowling. Possibly utilize an inflight adjustable propeller as well. That will be a fun challenge - for later!

Keeping At It!

Greetings! Ok, so I am thrilled to report that we have the wing center-section installed and landing gear is down and locked. Fantastic! That bit of work took all of the weekend of the 16th, 17th (yes, I did get the bolts that Friday). Including a very late Sunday night work party. We got a little punchy, but had fun too, notice the image where Scott was trying on the Flinstone style landing gear! I want to thank all our crew for helping out and getting that done. Well done! This pushed us past our road block and allows us to progress on all systems and components. As evidence, this last week and weekend was a beehive of effort. Here is a short list of items we touched:

Completed the fuel vent lines and they are final. Installed Curtiss drains in the fuel tanks. Installed the seat harness after reinforcing the aft spar attachment brackets. Completed the pitot and static hose runs and connected to the instruments. Installed the oil tank. Adjusted the location of the fake 50 cal guns. Final fitment and adjustments to the tail wheel strut. Final install of the rudder cables and turnbuckles. Fixed the left main gear leg scissors - they had sloppy bushing holes and allowed too much movement of the tire. That job required us to remove the lower strut cylinder and machine new holes for larger bushings and bolts. That is complete and much better - though not perfect. Taxi testing will determine if we need to attack this again. We started to install the control stick assembly and hit a snag. The new larger bolts in the spar splice plates are too close to the mounting bolts for the stick assembly. We are designing a new mounting installation and will be fabricating that right away. We determined to add fiber-frax material aft of the firewall up to the first bulkhead - an issue we have been contemplating for a while. After we add that, we can close up the lower firewall with the bottom cowl components this week.

Been trying to decide what to do for the canopy latch. Images of the early model P-40 latches showed a weird base for the crank handle. After accidentally seeing one similar in an internet search for latches and hand cranks, I realized that Curtiss had used an accessory hand crank handle from a Singer sewing machine. The old hand crank they would use instead of foot operation and as a quick bolt-on accessory for doing bobbins (according to my daughter). I’m guessing this drove the chain drive for the canopy with a 3:1 gear ratio. So, I purchased one of these on-line and will go about modifying it and making new housing and cover plates with the idea of making a latch for the canopy, not a full-blown crank-it-open chain-drive like the original had. This is a simpler and lighter canopy.

This week we will finish installing the control column, begin the fuel delivery system, install the lower cowl and cooling tunnel, locate firewall components, battery box, install the tailwheel control cables, and the elevator control push tube installation.

She is starting to look like an airplane and looking good too! Can’t wait! Keeping at it! Click on the pic to see the next one.

The Waiting Game

Hey everyone. Not much to write about for the last two weeks. We have worked on the center-section fuel tanks. installed and sealed the fuel draw tube assemblies into their tanks. Installed the fuel sender units with neoprene gaskets instead of the cork ones that came with them. Routed the signal wires, pitot tubing and lighting wires through the wings and through the fuselage. Small but steady progress. The wing attachment blocks were installed and torqued, then marked with torque seal. We have the rudder cables mostly installed and need to work on the tailwheel steering cables. So, not a lot, but something.

Main reason for not getting a lot of progress is due to having to wait for hardware to arrive. We need to install the wing center-section and landing gear to proceed with all the systems. We ordered close tolerance bolts for the wing spar brackets, qty: 8. Well, Aircraft Spruce split the order and I was going to get 6 in three days and the other 2 in 12 days. Dang. well I waited the three days and got 5. Then I called and informed sales that they shorted me a bolt. Well they sent me one with free shipping. A week later, the two back-ordered bolts arrived. But not the shorted bolt. That took four more days to arrive by USPS in a small envelope. Weeks dealing with waiting for some bolts. Never been like that before with Spruce. They are not the lowest cost hardware, but reliable - they always have it and get it right out to you. Not now. Not sure why. Might be the same reason that all our local hardware and lumber stores have empty spaces on their shelves. End of year accounting.

Well, we finally had all the bolts and Scott finished up a bunch of paintball gun parts for his project. It was time to test fit the wing with the new blocks and hardware. Well, it fit perfectly - except the close tolerance bolts were barely fitting. After looking at it and checking the dimensions, I ordered a size that does fit -but not perfectly. The next size down would work perfectly. Arrrrgh! I waited for weeks! Well, ordered the new size bolts and had them shipped two day air.

So, been forced into a slow mode at the shop. Nice in some ways. But it’s Friday night and I’m waiting for the UPS driver to drop off my bolts. Today is the day! We will definitely get the wing on this weekend - when I can get the crew to show up. Will follow up with pics of it up on gear! Better go check the front door. See ya.

Tail of the Dog

Happy Holidays folks! Been working on the rudder installation now for weeks - among some other things - and I’m sick of it! The issue is some binding as all the bolts are tightened up. We’ve adjusted shims and played with tightening sequences to no avail. Some of the things we did helped, but nothing we have been doing is totally fixing it. So, after much frustration and quite a few cuss words, we’ve thought about the best way to make new hinges for this rudder. Unfortunately, we can’t replace the hinges completely unless we build a whole new rudder (that thought has crossed my mind). We do have a serious Haas mill at our disposal and it can make quick work of aluminum billet.

The issue: Prior to covering the rudder, we had decided to bring the airframe to Sun N Fun and Oshkosh. So we had to hurry and temporarily install the tail surfaces. Well, we never fully installed the rudder until now. The vertical was not perfectly located and the rudder post wasn’t meeting the aft fuselage frame at the same exact angle. So, when tightened, the rudder post had a very slight bow in it. This created a non-axial condition for the three hinges. Not an issue when snug, but an issue when fully tightened. The rudder would swing pretty nicely until bolted-up snug. Then it has some major binding and requires a bit of force to swing it. Leg strength on the rudder pedals could easily overcome it, but it isn’t acceptable.

Attempts to fix it: at first, we were excited to bolt it up for the first time with all the zeal of the plane “coming together”. Well that quickly faded as it was pretty heavily bound-up. Its an hour to install the rudder and about an hour to remove. Several of the bolts are almost impossible to get a wrench on. Well, maybe it is sequence, undo them all and tighten from side to side. Didn’t fix it. Ok, one more time another sequence. Nope. What the heck? Consternation and cussin’. Ok, uninstall, check the vertical for alignment. Not straight. Oh boy! So we checked and rechecked. The vertical was not correct - fore/aft due to the fwd spar being about 1/8” higher than designed and a smidge to far aft. This caused the top of the rudder post to be aft 1/8” as well. Ahhhh, that would do it. So we designed a fix for the vertical stabilizer’s fwd spar mount to the fuselage - which required some adapter plates due to new hole locations. Installed that and checked alignment. Beautiful. Ok, install the rudder and - still binding. Arrrgh! Well then we adjusted the shims at each of the hinges and re-installed the rudder each time. Nothing is working. Ok, check the rudder for straightness - it was built in a fixture so it should be. Yes, it is straight. What the heck?!? I finally gave-up entirely. Had to think about it. Thought about making a new rudder. Thought about palm trees and hammocks. Ok, back to reality! Fix this!!!

First, the hinge design is novel and we should have just done it like on an RV-8. But, this should work. Installing and removing the rudder is a total pain in the a##! Redo that for the production model for sure! We have a large mill, can we make a new rudder post from a solid billet? No, too heavy and would likely change the way the rudder aligns with the vertical. Sight lines would not be right. However, we can make new hinge receiver blocks that bolt up to the existing rudder post and can be individually adjusted at assembly. The existing hinges on the rudder just slide over the receivers and then we can drill and bolt the rudder independently from the side. Installing and removing the rudder would only take a few minutes and allows us to bolt all the structure together without having the rudder in the way. Easy access to the hardware and checking of alignment. That way we can adjust everything to be perfect before the rudder is installed.

Scott got busy after Christmas and modeled up the new receiver blocks and machined them out. They look awesome and fit perfectly. We installed them and tightened them up. The structure of the rudder post and vertical was now complete and we checked alignment - fully expecting to have to add shims. None were needed. Straight in all axis between all three receivers by like .010” or so. Well within our tolerance on the hinges themselves. We then attached the rudder to the vertical and the rudder slid right on - with just a little resistance. No binding at all. We drilled and pinned the hinge brackets to the receiver blocks and re-checked for binding - none! Wow! First time in weeks! We are super happy now with the rudder installation. Time to finish the rudder cables and tail wheel steering cables.

We also removed and remade new aft spar attachment brackets on each side of the fuselage. This will help with as built alignment of the wing spars to the fuselage and with the seat belt attachment area. Checks and double checks of the mounting alignment and tolerances showed we need to shave the front mounts by .050” to have the spars slide in perfectly. So we will do that over the next few days.

Static ports and hose is going in the aft fuselage. Wiring for tail lights and trim is going in. Our engineers Paul and Aaron worked on the bolt sizing calc for the spar. The calculations for the wing attachment brackets are complete and we are way strong - good to go for wing installation! Having to wait for two bolts of the 16 that are on back-order from Aircraft Spruce means we will not get the wing on this weekend, but will be able to by the end of the first week in January. Tough break, but we will not sit idle. On-ward!

12 Days to Christmas

Hello again to all our followers of the project. Very sorry for such a long delay in writing a blog. Have no fear! We are still super active and engaged in the P-36 Hawk build. The Covid-19 pandemic has caused us some issues with not meeting with all our crew. Major strain on everyone of you as well - I’m sure! We have also had some delays due to finding and moving into a facility. We needed space to assemble the prototype and a home for some very large machining equipment for ScaleBirds and Scott’s paint-ball gun company. That took way longer than we anticipated and we actually completely installed the equipment twice! The first time was in our two car garage and what a job that was! We quickly found that the electric service on our street is not living up to standards and barely good enough for residential - even though we installed a serious entrance to handle rated line amperage. The line was under-performing and old. So, either pay huge money to upgrade the street, or find a new home. We did the later and we have a tremendous new facility at the local airport industrial park. We still had to un-install, relocated, install all over again and then improve the space with bathroom and air compressor rooms. We have added benches, desks, tables, tool boxes, storage racks, electrical receptacles for work stations as well as a fridge and microwave. I need a coffee maker for Christmas (honey are you listening?). It’s a great shop and the landlord is a private pilot and giving us a super deal. Thank you Kevin Cook! We now have a commercial address - still need to get the mail setup - so we will be able to have customers stop by and not have to deal with my home basement. We will still be fabricating parts and designing from home - I have a great shop there with suddenly more space in it.

Prior to all the equipment/shop effort, we prepped and painted the whole airframe in August. We were under-the-gun so we didn’t have time to blog about it - then jumped right into the machine space prep and install. No time either as that situation turned into a serious major catastrophe and then back to a super exciting and awesome ending.

The current situation - 12 days to Christmas: The airframe is mostly at the new shop. Wings and engine are in our hanger space. We have the fuselage in a temporary stand mounted to the engine mount and resting on the tail wheel. The wings are removed. We have installed the canopy, instrument panel and tail surfaces. We have replaced the wing attachment brackets with billet machined plates. We installed the fuel tanks and closed-up the inboard wing sections. This week we are replacing the aft spar to fuselage brackets prior to installing the wing center-section by Christmas hopefully. We are also chasing a little binding issue with the rudder - we have nailed that down to the vertical stabilizers’ fwd spar attachment. We are designing a simple fix and will get that ironed out in a few days.

We will have some extra hands on deck with the Christmas to New Years week off from the day job. The plan is to have the airframe out of the fixture and standing on its gear legs with the engine re-attached. Flight controls installed again and rigged by end of the year. Early January should be wiring, pitot, fuel and brake lines. Then fairings and cowling installation. We will be making a very concerted effort to keep you all better informed and show more pics and some videos. Scott has been posting images to Instagram and Facebook.
