Washers (nylon or metal) are required under PK screws per the Poly Fiber instruction manual. They prevent the fabric from twisting under the screw head. You can also get the covering drawings from Univair to use for drain hole locations, inspection panels, etc. The Stinson drawings require about twice the drain holes as the Poly Fiber manual does, but its nice to see what the OEM designed.

I’m going to use an old damaged aileron and do some testing with some Oratex samples. I will do a video and share. Most interested in how some colors are translucent and others are not.

Looking forward to it. I'm still conflicted if I'll switch over to Oratex Red or stay with the fabric I have.

Tore apart my control column today. Sending it for powder coating along with yokes, battery box and a extra
control column.

I'm sure you noticed, but in case anyone uses this thread in the future: The left and right aileron pulleys are different in the lengths of the shafts to achieve the stagger of the cables to the center pulleys. One is shorter (the right one?) It allows the yoke shafts to be interchangeable in theory, depending on how the u joint bolts are drilled.

Good intel! I did video the routing of the cables, but failed to “tag” each individual cable before I bagged the parts.
I plan to repacks all the bearings and pulleys.
I guess I can measure the cables when I get ready to re-Assemble and ensure I follow your post above.
Thanks

I think my Universals are in good shape. Replacements are $250 each and I heard about one from McFarlane failing, so I think I will stick with the originals.
I need to replace the bearings, and pulleys, anyone have a better source then Univair?

Hands down the best stuff to use to lubricate and free up stiff joints, bearings etc is CorrosionX. It's a spray on corrosion inhibitor that stops rust in its tracks. Not cheap, but waaaay better than WD40.. I spray the insides of the flying surfaces and it drips for weeks - leaves the outline of the aeroplane on the hangar floor. It works its way past rivets as well...

The shaft is shorter on one side, no idea if the cables are shorter. Not trying to suggest how you restore your airplane, but bearings and pulleys are cheap, and they are probably the originals. This stuff doesn't even move a full turn, so they tend to wear in one spot over the years.

Busy day in a cold hangar, (well Texas cold 35’). Even with the blow heater it was not great.
Anyway bought a new large sandblast cabinet from “FB marketplace” for $100. I did put it on casters and raised the height by 4” bc I’m 6’6” tall.
Also build a spray booth by cutting 4x8 sheets of insulation and duct tape, total cost $22. I’m going to use a box fan and filter to help move the air.
My first thing in the San blaster was the aileron pulleys from the control column. I expect the control column back from the power coating company soon and all new bearings and pulleys.

I also measured the P/N 41001 pulleys for the Rudder cable AD also. I would like to find a match that is less than the $150 per pulley that Univair wants for the 41001.
