Getting a handle on things

I decided to hold off on finish welding the fuselage until my tech councilor could check it over and, if necessary, I could make changes while it was still relatively easy.

So instead I started tackling smaller projects.

I started by welding up the control stick. Then moved on to rudder pedals, torque tube, and the forward torque tube bracket. I bought myself and entry-level TIG welder and after a bit of practice I thought I would try it out on some airplane parts. The rudder pedals, torque tube, and mounting bracket were all TIG welded. The pedals turned out okay, but I had mis-measured the scrap I made them from and they were too short. The bracket turned out great, TIG made welding on the little sheet-metal feet pretty simple.

The torque tube was... not great. All it consists of is a 1" diameter tube with a steel bushing welded on in the center for the control stick to pivot on. But, try as I might, I just could not get that stupid little bushing to weld on right. I welded most of the way around it, but the last little section of weld just kept bubbling and spitting like I had no argon, but I could hear the argon running as I welded. I ground that section out over and over, but couldn't get it to weld. Finally I pulled out the oxy-acetylene torch and welded it up no problem. Well, small problem, the bushing was off center and made the control stick bind. Sigh. I cut it off, made a new bushing but left it long so I could trim it to be perfect. Had the same bear of a time trying to TIG weld the new bushing on. It went better, but was still a pain in the tuchus. This time I realized what I was fighting was probably air trapped in the space between the bushing and torque tube. When I finally got the weld finished I trimmed the bushing, tested the fit, and... somehow I cut the bushing too short. Out came the grinder, away went the bushing. I'll try again later and probably drill a vent hole under the bushing to let any trapped air out. We'll see what that does.

I also took this time to finish-weld the stabilizers, elevator, and rudder, then straighten out the resulting weld distortions and add hinges. Apparently I didn't take any pictures of that; too busy working.

Fittings. How fitting.

Not much has happened on the Ace this year. The winter was long and spring has been very cold, so I spent a long time waiting for the garage to warm up. Now that there's a little heat down there I've been making some headway on the next step of my wing build: fittings. I copied the parts off the plans into CAD and then printed them onto cardstock to use as patterns when laying fittings out on the steel stock. First I tackled the brackets that will hold the pulleys for the aileron cables. I have a lot of extra material in case I had to remake these. The next step was to bend up my fittings. There is one fitting that mounts to the forward side of the strut which gets bent to a 90° angle. The fitting which mounts to the aft side of the spar gets bent at about an 85° angle. I forget the exact number, but don't feel like looking it up at the moment. Next I cut out the aileron control horns. My Harbor Freight porta-band chucked into my vice works well for cutting th...

Gear Legs

Last updated November 8th, 2022!? Time sure gets away from you sometimes, doesn't it. Woof.. A lot of time was spend figuring out main landing gear legs. The first step was taking the info from the Piper drawings and laying out the gear v's full size on my table, then jigging the parts in place. This is what we're building. The left side of the picture would be facing the front of the aircraft. And here's the jig laid out on my table. The nearer jig sets the relationship between the forward tube and the axle. The farther jig aligns the forward and rear tube as well as the bushings on which the gear leg will pivot. With the jigs laid out it's time to manufacture parts. First came the pivot bushings, and they were a bit of a process. First the little U-shaped piece of metal that holds the bushing needs to get bent to shape. I made a little die the right size to bend the material in my vice. After the U is bent it then gets a notch ground out to fit around the...

Drag wires

Progress on the airplane has been very limited as of late. It has, however, been made. After a long episode of researching and calculating I have found drag wires. Not the drag wires the plans call for, but still. The plans want 1050 alloy steel wire to be threaded with a #6-40 thread and retained with what are essentially spoke-nipples from motorcycles wheels. The aircraft rated nipples are about $7 each and I need 24 of them. Spoke nipples are 20 to 50 cents each. We'll, I wasn't going to spend $170 on bolts, but $12 seemed reasonable, so I ordered a bunch of spoke nipples. I had intended to match the thread of the nipples with my drag wire stock, but they are just irregular enough that I couldn't find a thread that matched and it seemed like sending wires out to have the correct thread rolled on wouldn't be worth the effort. So, despite having bought my spoke nipples, I abandoned the idea of using them. Enter the Baby Great Lakes. I researched drag wires and alt...
