I can't find a tapered spindle for a 1 / 2 inch threaded shaft
on a 1/ 3 horse bench grinder I wish to use as a buffer. Rio
has a picture of one that might work but at $25 each one on each
end would be more than the grinder is worth! All the spindles I
find are for non-threaded shafts. Any suggested sources??
You?re probably looking for trouble ordering threaded spindles
sight-unseen. Thread matching is tricky at the best of times-
remember that you must match the number of threads per inch as
well as the thread diameter. If the grinder was fairly cheap,
then do as I did a month or so ago- slice the threads off the
shafts by holding a hacksaw blade against the base of the thread,
motor going. Dangerous, but fun... I secured my non-threaded
spindles by filing a small flat at the point where the grub-screw
made contact with the shaft. You could even tack-weld or braze
the spindles on if you are really worried.
