This weekend, I moved to a new house. Currently, my biggest machine is a delta contractor's saw. In anticipation of the move, I built a little mobile cart for the table saw. Took a look at the wheels on most mobile bases and visited home depot. I'm likely to be in this house for a while, but could easily move again in the future. Here's what I learned:
2" diameter wheels are nowhere near big enough. I ended up being high-center with my mobile cart at the top of the ramp. Also, they caused approach angle problems when getting on the ramp. Which lead to observation #2.
Bolt the mobile base to the tool somehow. The table saw came off the base a total of three times. Once while loading, once in the truck (must have bounced off), and once unloading.
I think I'll remove the metal legs and make a cabinet type thingie with drawers a built-in router table, and dust collection... with 5" diameter wheels.
