Castor Questions?
Barry Irby
I am still thinking about keeping the drum sander I bought at auction. Its too big for my shop but.....
It has a Shop Fox mobile base under it now. The base may be overloaded. Whoever installed it added some home made clips to hold the base on the machine, I guess. There is a bolt at each corner with the head down. The problem is the ground clearance on the base is very low by design and the frame has deflected a bit and the heads of the bolts sit on the floor, completely defeating the purpose of the "mobile" base. I could remove the bolts and give it a try, but I am suspicious the base is too light duty. A heavy machine like this does not lend itself to fiddling around.
I need to raise the sander a few inches so the material being sanded will pass over my TS. So I am trying to decide whether to add some spacers to the existing base or make a new one with some really heavy duty wheels. The sander weighs 450lbs.
What does it mean when a castor is rated at 600 pounds? Does the rating mean each wheel could support 600 pounds or that four of them will?
My thinking is larger diameter wheels roll better. Heavier duty wheels roll better and last longer. These wheels will sit for long periods and then roll about three feet and then back.
Anybody got any suggestions?
