I got a tool & cutter grinder head from a junk shop (for free) that is
missing the arbor nuts and outer collars.The bearings are in good shape
as well as the motor itself.
But I can't find the arbor nuts.
I've measured the shaft and threads but I can't decide if they measu
16 mm x 1.25 mm
or
5/8" by 20
I suspect that either one wouold work after a fashion since neither
seems to be an exact match for the thread pitch.
However, my regular sources for odd size stuff (
www.boltdepot.com and
www.fastenal.com) don't list either one of these sizes.
It seems a shame to toss the work head just because I can't locate a
couple of arbor nuts.
Any ideas?
Gary
PS The work head is completely unmarked - other than a switch saying it
is rated 15 A at 125 VAC.
