[TheForge] Source for Non-Standard Grinding wheels

[theforge@mailman.qth.net]

I have a lot of old hand cranked grinding wheels that I have collected 
and refurbished.  I use them on Boy Scout campouts for teaching 
blacksmithing.  With this set up, I can oversee them through the entire 
process of forging, finishing and polishing out a knife.  A bonus is, 
while I would never allow an eleven year old to polish out a blade on my 
  baldor buffing set up, a four inch hand cranked buff will give a 
mirror finish and is nowhere near as dangerous.   I have one grinder in 
particular that I have converted to foot power.  It is unique in that it 
has a double shaft.  I have mounted a wire wheel on one side.  The other 
side has a really long shaft and came with a 3" diameter wheel, with a 
5" face.  I cannot find a replacement stone.   While I could gang 
together abunch of smaller stones, I would rather not.   Does anyone 
know of a source for wheels of this sort?   I really have gotten to like 
this grinder. It is mounted to the back of my post vice stand, and is 
dandy for knocking scale off with just a couple of pumps of my foot.  I 
guess if I can't find a wide wheel, I will set it up with two wheels , 
coarse and fine, with a two inch spacer between.
