Dan Oelke Posted October 20, 2014 Report Share Posted October 20, 2014 My dad came across this hand-cranked grinder from a relative's place as they were cleaning it out. Very cool looking with open gear set up. I haven't ever seen a grinding wheel like this. It has a spoked metal center and the abrasive is just a 3/4" layer formed around the outside of that. Unfortunately, the abrasive had been cracked and broken off of the wheel at some point. We still have some of the pieces but not all of it. In the photos the rustier wheel with the little nubs on it is the grinding wheel. While we could replace it with a more modern wheel that is all abrasive, I would much rather be able to get new abrasive put on the old wheel. Those spokes are just so cool I think. So - does anyone have any ideas on where/how to get a new set of abrasive formed onto that wheel? Also - anyone have an idea as to the manufacturer? We could find no lettering/markings anywhere. Thanks! Quote Link to comment Share on other sites More sharing options...
ponderingturtle Posted October 20, 2014 Report Share Posted October 20, 2014 What is the Diameter of the wheel and can you take it off the arbor? I think you are not likely to find a wheel that has a cast iron core like that, but you might be able to adapt it to work with normal grinding wheels.

Rick A McQuay Posted October 21, 2014 Report Share Posted October 21, 2014 Unusual grinder. I would be very surprised if an abrasive wheel exists to fit. An alternative would be to make a wood tire and glue sandpaper to it. - sent via Tapatalk Quote Link to comment Share on other sites More sharing options...
Trip Posted October 21, 2014 Report Share Posted October 21, 2014 Send the photo the The Schwarz. He usually answers eMail from his lostartpress account within 24hrs. He's totally into hand-crank grinders... If you strike-out there, go with RoyU -- he answers email also in about 24hrs.. 1 Quote Link to comment Share on other sites More sharing options...
Dan Oelke Posted October 22, 2014 Author Report Share Posted October 22, 2014 Thanks guys. I probably will try Schwarz or Roy. I didn't measure the arbor diameter but I probably could find/adapt a modern wheel to fit. There is a pin that holds the curent wheel on the arbor. It's just that the cast iron center is so cool looking that I'd really like to keep it. I am hoping that someone somewhere can form a wheel around that core.... but to find them. I did google making your own wheel and I found a few people saying that they thought you should be able to make a mixture of Al-oxide and portland but no one talked about having actually done it.

ponderingturtle Posted October 22, 2014 Report Share Posted October 22, 2014 Maybe go a different way. Instead of using a stone maybe a leather belt loaded with coarse lapping compounds? Maybe felt? 2 Quote Link to comment Share on other sites More sharing options...
