Default Is this OK for support?

I utilized my 2 post car lift and tried to make a couple of support cradles...seems to work fine but I don't want to put too much stress on belly and cause any damage...


I plan to build a wood frame at some point and place on some castors for mobility...but can at least get started removing engine mount now...and it will sure make for an easy belly cleaning!!!
I would really appreciate comments/feedback constructive criticism on my supports.

Charles,

Without the engine, there is so little weight that I don't see any issues at all with what you are doing. Just make sure you are supporting at the spar in the front and a rib in the back. But again, so little weight.

A bigger issue is going to be your getting tired of walking around and over the hoist all the time. You will find it a real pain after awhile

BTW, nice work space!

Repaired an RV-8 that had similar damage. One thing that helped a thousand percent was the ability to roll the airplane on it's side to have easy access to the bottom. I just inserted a short false spar to one side of the fuse that extended past the bottom skin overhang and bolted two one/bys to either side of it and extended them up the fuse and mounted/clamped them to the fuse deck. Rest the tail right ahead of the stab/rudder on a padded frame that is tall enough to clear the elevator when rotated.
Cant say how much this helps with access to the bottom of the fuse. Must have rolled that thing a hundred times.

Default Thanks!!

I really appreciate all the comments and help offered! I am getting pretty into the repair at this point. The hoist has sure made it nice to raise and lower to comfortable working height for whatever area I am working on. Including the underside! And I can lower it almost to the floor to access over the top!
I have de-riveted all areas and am working on straightening a couple of minor wrinkles. Have ordered all the parts needed...well, MOST, from Van's...new lower gussets, longer gear leg/engine mount, and the new epoxy cowl kit!
Question...I am attempting to straighten the small wrinkles at the lower corners...as I don't see how I can replace the complete side skin as the overlap joint appears to be under a bulkhead (404)...which I guess 404G could be removed for bucking access...?? Comments on wrinkle repair vs complete skin replacement??

Default TBI and slosh

Mr. Charles,
I had a similar incident with the Ellison TBI dying on me at low idle, and found Slosh fuel tank sealant in the tanks had started to flake off. Most of the older RVs used this material for fuel tanks. The small particles had evidently clogged some of the openings in the TBI. It didn't show except at idle since the mixture adjustment is different for idle and normal operation. Sent the TBI back to the manufacturer and had the terrible task of having the slosh removed and tanks resealed. Readjusting the mixture for idle usually takes a few tries, but then it's a great system. Good luck on your repairs, and it's worth it.
