DUplex Toolpost Grinder

(1/1)

Twizseven:
I  have had a Dupex Toolpost Grinder for several years but never really needed to use it.

I now need to very slightly reduce the diameter of a hardened 90 degree seatcutter.  I have  made and fitted guards for the wheel and the belts, ordered a new belt but am struggling to find a source for suitable grinding wheels.

The wheels need to be 3″ diameter (or 75mm), 1/2″  thick and with a bore of 1/2″.  I have managed to source some 1/4″ thick wheels but cannot find any 1/2″ thick.

A Midlands grinding wheel specialist can machine a 5″ one down to 3″ but will have a 2-3wk wait.  Does anyone have any ideas on sources or even have a spare wheel they have no use for.

It is a Model D22A running at 1100rpm.  Capacity is given as 3″ x 1/2″.  Would I be correct in thinking that I could go smaller, say to 2″ diameter, safely.

Many Thanks,

Colin

Might be worth checking out Hemingway to see what they have for the Quorn grinder.  My Quorn is presently set up with a wheel about 3" dia and 3/8" thick, one of the older wheels supplied with my Quorn kit from MES originally. Dave
