As usual - both ways work.
With the casters -- you want to have some good solid bracing on the bottom of your cabinet to mount the casters to. (something I learned the hard way).
With the mobile base -you are actually adding structural bracing.
A THIRD option -- especially if you may have some rough ground to cover - is what I did when I built a base for my benchtop. It frequently finds itself rolling across back yards etc so I shortened the back two legs and added wheels. When in use the front legs provide the 'brake'. When I need to move it -- I rock it back -- and essentially have a built in two-wheeler. |
