Shop press size?

Any issues with the bottom rails flexing because they're not sitting on the floor? I like the idea, would make it easier to deal with mine. Even when it's out of the way it somehow gets in the way. :lol:

I haven't noticed any issues. I'm thinking all the force is between the two bed pins and the ram bridge. I've done several axle sets and carriers since bought. Some 1/8" (slow motion) bending with a 90° Vee fixture.
I'm sure I've never come anywhere close to the "20 ton" rating on anything. Lol, I'd bet the plates that came with it would pop if I did!
The wheels are a definite convenience for me.
