FLAPERON SPAR TUBES?

[EDMO 1078]

Are the flaperon tubes aluminum or steel?

The ones I've seen are aluminum.  Jim Chuk

Mine are aluminum as well

Thanks Guys,

I bought steel before asking - got to go back and get aluminum now - I should have checked first.

I'm pretty sure mine are steel. That is on an Avid Model C. I will check this weekend but I remember that they were not that easy to drill through when I added a few rivets during rebuilding of the one that came apart on me.

While we're at it anyone know what size the tubing is and how thick? I want to make new ones and extend them 3' to match the extension I did on the wings. 

 

Also what is used for the bearings? looks like some sort of tubing from the plumbing supply store. as for the covering I'm thinking of using flashing material such as http://www.acehardware.com/product/index.jsp?productId=29795066&KPID=984477&kpid=984477&pla=pla_984477unless anyone has a better solution or good reason not to. it does say "aircraft max" after all doesn't it

Robert,

I can tell you tomorrow. I have a cut end of one in the shop - Just guessing, I would say 3/4" x .065 wall. You could make your extension out of 7/8 x 062 so it would slip over the old tube and get riveted at both ends.

I believe PVC pipe is used for the bearings??

The flaperons are about 9" wide, so you would need about 18" flashing to make them.

Robert,

I measured the tube today and it is .750 diameter and .100 wall aluminum.
