Jack stands work great! You can cut an old piece of carper into strips to wrap and extend the cradle. I duct taped mine the first time with some foam carpet padding. I think it lasted 2 or 3 years like that. I attached it to a base (using a metal flywheel from an 18 wheeler as the base) with screws and a couple of brackets the hubby made. It weighs a ton LOL but it is stable and as safe as I could make it.
I should mention I ground the teeth off the flywheel before using it!
