Rocket Jacking.
No, not a terrorist attack, or a porn site... but how to raise your
Rocket safely.
First let me say, don't you guys ever read my website? You are truly
missing out on the world's foremost source of Rocket info, the oldest
Rocket site out there and still the best. Prove me wrong.
I had a worm clamp like Tom Martin describes fail on me while raising
the plane. It does work, but be sure to use a quality clamp if you do.
This was during the gear leg shortening described on my site... so I was
asking a lot of the little clamp.
Here's a couple shots of a pair of ordinary wing jacks being used under
the motor mount. I made a couple of simple saddle pads that fit the top
of the jacks and nested under the lower mount tube. This is a very
sturdy, safe way to lift your bird since it keeps the weight right next
to the gear... where it is normally found anyway!

This is an EASY and STRONG jacking method. Weld a plate to an exhaust
clamp and stick a jack under it. I can almost hear the whining already,
"Ew, ew, won't that scratch my axle socket paint?" No, not if you're
careful. And it's much better than punching a hole in your wing if
you're tempted to use the wing jacks under the wing. I've used this
setup THREE times on my bird so far, and the paint is fine. But, touch
up the paint if you aren't so lucky. 'nuf said.

I'm not a big fan of using straps on the engine mount, although I did it
several times during construction when the total weight of the plane was
hundreds of pounds lower. Just don't use the lifting eye on the engine
unless you want to risk cracking the case. Ouch.
