Aileron Push Tubes

[SeanB]

I decided to go the "weld it" route on the aileron push tubes. The results look good. Just gotta finish the prime and paint of the outside. Pics: http://websites.expercraft.com/sblai...y&log_id=58919

I've read in the archives that some have drilled a 1/8th hole and added line oil to the inside of the tube for corrosion protection, then plug with blind rivet.

I primed the inside of these tubes prior to welding. Should I assume the welding heat wiped that out and need to go the oil route? Any special rivet...just a blind / solid one?

Where do I get the oil?



Thanks again.

Linseed oil is what the old timers used on chromemoly tubing. After it is sloshed around from end-to-end, it was drained and the hole welded up.

Best,

Thanks, Pierre. Sounds easy enough.

Amazing. You are building another RV! Excellent. That you are building it at home means that you don't get to see all the wonderful RV folks at Meadow Lake. But you get to see your family more.

Hey Ron.

Yep...been back at it for awhile. Working at the house is sure nice and more productive. An hour here and there adds up.

Tell the gang at KFLY "hi" for me.

BTW...last they knew, I was building a nosedragger. Keep 'em in the dark.

Sean,

Check with John - he did his the same way and used somebody local.

Hey Bob,

Will do.

Thanks,

If you primed the inside prior to welding you will need to apply primer through the tapped hole and slosh around over the weld.

I had mine welded. I would not drill any holes. No moisture, no corrosion.

Bruce,

Too late...1/16 hole was already drilled by welder. I thought this had to be done because of the heat and two closed ends to relieve pressure during welding. Saw that on other VAF posts. Guess not???
