I’m renovating a 6" Beacon Star Super lapidary combo
(saw/grinder/lap) unit - which has seen better days.
The grinding stones need to be replaced (they’re about 3" diameter
rather than 6") - and, while I’m at it I’m going to try and replace
the bearings, which are currently a bit sloppy.
The strip-down of the main shaft has been OK so far - all the screws
and Allen setscrews have come undone - but I can’t see what’s
holding the bearings in place. Are they ‘fixed’ in some way - or are
they held on by rust ? I’ve not yet tried WD40 - I guess that’s
the first thing ?
This machine seems to be based in ‘inches’ - I managed to find some
metric bearings that are the correct outside diameter, but I think
I’ll need to ‘invent’ some thing metal shims to make the new
bearings snug on the old shaft - think this should work ??
I’d appreciate any comments from anybody who has been here and done
this - before I get the big hammer out !
