Cab stand questions

[zellway]

I'm looking into making a cab stand that can be used to work on (welding and sandblasting) and paint the cab on. I would like to use this one on a few other projects down the road so I wanted a metal frame. I know I have seen a ton of cool one in different builds on the forum. I found some specs for the base. What I would like to know is if anyone that has made one would have done anything different. In talking with a friend he told me he would have liked it to be shorter and have locking casters and all the casters would swivel. Any one have any pic's they would like to share?

Attached is the pic I found with specs for the holes in the floor of the cab.
