Ok folks-
THE BEST casters at
THE BEST prices come from
Hartville Tool. I have them under
ALL my machinery (tablesaw, jointer, planer, shaper, bandsaw, drum sander, router table.) They are full ball bearing wheels, have really strong mounts and have dust shields over the bearings. I primarily use the $4.49 3" fixed wheels
which are rated at 220# (4" are rated at 275#)
each at one side of my tools and a "Delta Style" step caster, $15.99 from
Rockler at the other side.
This essentially makes a sturdy and cheap (less than $25) integral mobile base. After cutting off the top bracket, I attach the step caster to the underside of the front of the machine sub base. After removing the axle bolt and removing the wheel from the mount, I remount the Hartville casters in pieces of rectangular steel tubing which I mount directly to the back sides of the machinery sub base. Here is a pic from a
thread about the base I made for my Unisaw. The pic shows the rear wheels but the step caster installation is slightly different, though, since I mounted the step caster on the extension table legs instead of the saw base.
I also used the $6.99 3"
Hartville locking swivel casters, which are also rated at 220#, under my clamp rack.
My old ISP is going away so let me know if any pics do not appear (I may be seeing cache copies)
