Lower skin

I didn’t do much today but I got some stuff done. I used my orbital sander with 2 scotchbrite pads cut to size to scuff and deburr all the holes. I also marked lined in the blue plastic and scuffed the edges that will be hidden by the left & right skins. After that was done, I dimpled. and dimpled, and dimpled some more. Low behold I have a freshly scuffed ready to primer skin waiting for me.

Getting there

Today I received a letter from Van’s notifying me that my wing kit will ship on the week of June 2nd. This give me about 7-8 weeks to get ready for the wings. I started off by cleaning the stiffeners and longerons that I finished yesterday and finished with priming them. I had to stop for a bit while I sold a motorcycle and went to flying lessons. It was a bit bumpy but I got some landings in New Haven (KHVN) while it was incredibly busy. I thought the poor controller was going to pass out from all the talking he was doing. On the way back I got to do some instrument work for the first time. So far that seems easy.

When I got back i finished cleaning the rest of the stiffeners. While those were drying I prepped the remaining parts I had yet to scuff.

 

 

Once I had those parts primed, I started reviewing the drawings and see what I hadn’t done yet. The next thing I decided I was going to work on was the battery & bellcrank mount. This required separating a few pieces from 1 extrusion. There really wasn’t much to do here. I deburred all the edges, drilled holes to the proper size, and countersunk a few rivet holes. After priming I riveted the nut plates on.

Tomorrow if I’m motivated, I will start working on the skins if I can’t find anything else to avoid working on them.

Scuff work

Yesterday I got my new countersinks from Cleaveand Aircraft Tool. Today I literally sat and deburred holes and scuff the stiffeners. After scuffing each one I dimpled each one. This broke up the monotony of scuffing and deburring. After I was done I did a much needed clean up of my work area.

Longerons & Elevator Bellcrank

Today I started by counter sinking the Longerons. This was going swimmingly till the shank on my counter sink got stuck and broke with only 3 holes left. While that was pretty depressing, it left me with few things I could work on till a replacement came in. The elevator bellcrank assembly was pretty easy. I had to cut apart the pieces and deburr the edges. That was followed by match drlling everything and priming them. I also ended up priming the F1085? rudder cable bracket as well

 

Since it was getting late I hopped on Cleaveland Tools web page and ordered a some countersinks, a dedicated deburing tool, stainless tie down rings, tail light adapter ring, Push on Static Ports, and some 1″ 3m wheels.

I am ordering the SafeAir1 Pitot-Static kit, but I don’t like the way the SA1 Static ports look.

Tailcone Work

Today I started off by deburring, dimpling, and scuffing the F1012A,B,E, F1014, F1056, That was followed up by a wash & prime. While they were drying I began work on the F1011 bulkhead. Just basically repeated the same thing.

Once these parts were dry, I riveted them together. After that I began working on the F1010 Bulkhead & F1006 Bulkhead.

I did determine while this method takes a little bit more time, it makes parts management far easier. I would not recommend this if you were mixing & spraying primer.

Disassembly day

Today I started by finishing up some odds & ends prior to disassembly. I finished making the F1011D & F1012D angles.

F1011-D

F1011D Complete

After completing these parts, I matched drilled all the holes in the F1014 skin. Next I clamped the newly completely angles to the F1014 skin and began match drilling all the holes in them to the F1014 skin & longerons.

Next began the process of placing the rear passenger seat belt attachment anchors. This was pretty easy to accomplish.

Next the plan’s call for a line to be drawn on the triangle of the right side skin so that it could be cut off. This was quite nerve racking in its own right as I was worried about butchering the cut. I ended up using my snips and cutting piece by piece until I was really close, then finished it off with a grinding wheel.

Next after disassembling everything. Boy that was disappointing I tore off the blue plastic on the insides of all the skins and all of it on a bunch of pieces. I skipped ahead a few steps and drilled the 11/16″ hole for the rear tie down point. I also sanded, deburred, & dimpled 1 stiffener. I am thinking of deburring the pieces as they are called out to be assembled. This will break up the monotonous of scuffing, deburring & dimpling. I think this will only really work due to the fact I am using spray can primer.

Match Drilling

Today I finished up match drilling the skins. Nothing too exciting. I also began working on the F1011-D Attachment Bar Support Angle & the F1012-D Elevator Stop. By that I mean, I just cut the pieces and called it a night.

Tailcone work

Today I finished drilling the left side longeron. After that I finished match drilling all the holes in the skin. This wasn’t as bad as it has been in the past as I already had drilled most of the holes in previous steps. After that I installed the remaining bulkhead & stiffeners and installed the top skins.
