Where is the plywood on a 767? I miss the wood block on the engineer's panel of the 727. I never did know why it was there.

That spar looks like a newsletter article.

Caveat emptor, but I was happy with the spruce beam that I ordered.

I grabbed one from my stack. It's not an end rib. It weighed in at 229 g.

Does anyone know how to waterproof a pickleball?

FYI
When I try to go straight to pietenpols.org, I get "ArgumentCountError thrown"

My plans (1975 by Kapler) say .080 for the center section.

I’ve pumped my fair share of avgas.

How are your center section gas tank straps attached to the airframe? Did you drill holes in the spar?

Plywood was soaked in hot water for about 15 minutes. Pipe was heated with a heat gun. Used water and a sponge to keep plywood from drying and getting singed. Left the clamps on until dry, overnight, I think.

Does anyone have any experience with a riveted fuel tank sealed with phenol novolac epoxy, brand name Caswell?

Any other recommendations?

Thanks.

Use of acid-based strippers, chemical removers, or chemical conversion coatings are not permitted on steel parts without engineering
authorization.

And yet I'm still tempted to give my steel parts a phosphoric acid bath before priming. Any thoughts or experience?

A friend cut a piece of steel into strips for my center section fittings. Unfortunately, he left me with rust and tool marks to contend with. I've sanded with 80 and 120 grit sandpaper. How fine do I need to go?
