Today I put a set of Bora caster/lift set under my bandsaw. Really nice. To get it on, I used my engine hoist, just cranked it up. But the darn casters on the engine lift are garbage and don't swivel. So, I went looking for replacement casters. 3 1/2 inch. Guess what? Wheels that size are rated for about 350 pounds. 2000 pound lift and needs to support almost full weight on one end. About 700 Lbs per caster would be a good design. Thank you Harbor freight for grossly under designed garbage. Had to order more garbage casters as I will need the hoist to get my new saw off the pallet next week. Next design is a frame for the saw, extended to the side to support the router table.
