I built a stand for my (new to me) drill press! Everything is nice and square, and I'm really proud of the result. And then I put it on my not so flat garage floor... And the locking casters aren't all that effective anymore. It's also pretty wobbly. Any tips for placing movable tool stations on wonky floors? Smoothing the floor sounds like too much work!
3 castors will ensure no wobles, the top might not be level, but it will be solid. The other option is leveling casters, which are a pain if you move as you need to relevel them after moving, and then retract before moving again.
Well there are ways to have something level itself. However none are easy.
