I assembled a radial arm miter saw workstation. On both sides there are long workbenches for processing long boards. I have a T-rail with a stop block and there is a large unused area behind the rail. I made plywood platforms and attached these casters to the floors. Then I attached my drill press and portable band saw table to the platforms. They sit comfortably at the back of the workbench and slide forward when needed. The rollers roll smoothly and traverse the T-rail with no problem. The locks are a little tight, but the tools stayed in place when turned on.
