Hey David, et al,

That's a sweet jack!  I'm on it.  Looks like:

https://www.toolsmithonline.com/products.php?product=Powerbuilt%C2%AE-3-Ton-All%252dIn%252dOne-Bottle-Jack%7B47%7DJack-Stand

has the jack/stand.  I assume you haven't had any problems with the safety ratchet?
A quick google search turned up several complaints of Powerbuilt's regular
jack stands failing -- evidently cheaply cast China ratchet.

About the wing tiedown not being flush with the skin:  I've made a stud that screws
into the tiedown with a shoulder on it so that the weight is on the threads,
not the skin -- is that a bad idea?  better to spread the weight on the skin?

I'd still like some examples of when both wheels need to be jacked off the ground.

Just a thought about using the engine hoist point to raise the nose wheel:  with
the engine mounted, the tail acts as a counterweight and the force on the hoist
point is less than when lifting the engine by itself ... so what could the
problem be?

Later, - Lew
