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.
You might get away with using two no swiveling casters on one side (none on the other) and putting a handle on the other. When you need to move it you just lift the handle and pull it around, otherwise it shouldn't move much.
