Lifting Eyes for J-3 Cub

[Skywalker]

Burl's has a bolt on lifting tab, just have to make a slot in the skylight.

before metal tabs we used nylon lift straps around the front spars...left them on when done and reinstalled covers

CubCrafters lift ring is a round section steel rod formed into an inverted "U" with a plate welded to the inside of each end of the "U". The plates are parallel to each other and at right angles to the axis of the "U". The plates are drilled and the front spar attach bolts pass through them. Needs a longitudinal slot in wing root fairing and it leaks like a sieve in the rain. Not hard to fix but they didn't bother on mine.

CubCrafters cautions that a spreader bar must be used or the lift rings can rotate and damage the root fairings.

(All from memory and I don't have a hoist so my aircraft has never hung on them except at the factory.)

The j3 the spars are in the middle of the fuselage.

Yes, the J-3 spars end in the middle of the fuselage, and in any case, the spreader bars aren't intended to protect the wing root fairings.....lifting without a spreader bar can fold the entire top deck up, and dramatically increase wing dihedral.

A herring boat crew in Kodiak demonstrated that quite effectively. Pretty impressive, but they had to find another spotter for the rest of their season.

Do NOT lift a Super Cub with those rings without a spreader bar.

Good information. I’ll hopefully have a combination of all of the above cranked out soon. Thank you!

I merged this thread with an older one that had some good pictures and suggestions as well. Go back to the top of the thread to see the earlier posts.
