I'm planning to build a movable workbench and I was curious what the best setup for casters would be. I was thinking 1 locking at each corner, but that looks a bit overkill. Are two locking casters enough to keep the table in place? What about using chocks instead? The pricing of locking vs. non-locking casters is fairly high so I'm looking for a more economical solution. Also, is there configuration of 1 at each corner appropriate or should I consider adding a fifth caster in the center?
The best set-up for maneuverability plus stability to to allow the workbench to sit on fixed legs. When you want to move the bench you can implement a jacking system with the casters similar to
I have seen this implemented with a rope where you can pull the casters down underneath to lift the bench or with a foot operated jack similar to some table saws such as
Hope this helps you out. I've tried the casters with 2 locking casters and I've never been happy with the stability of the bench.
