Tool Grinder (maybe)

[f350ca]

The ice skate grinder that Sasquatch spotter on the bench turned out to have tapered roller bearings in it, and was set up for 1 1/4 bore wheels. Has nice felt dust seals and a convenient flange mount to bolt it to whatever housing I come up with.
Roughed out a disk to bolt metal backed wheels to and shrank fit it to the mandrel. Then turned it true with the shaft between centers,





It was originally set up with two washers to hold the wheel.



Can now use the metal backed or conventional cupped wheels.





Interesting notes on the spindle.
When I had it between centers where the bearings mount showed about 1/2 thou runout, not bad and the mounting dia for the wheel about a thou.
Now mounted in the housing the wheel center shows 2 thou runout and the backing plate about 1/2 thou wobble. The bearings seem smooth but must not be true or the runout on the bearing points weren't in phase, never checked that.
