Got my surface grinder today.

The important thing about the contact wheels is their quality and the hardness of the coating. Mr. Rietveld's wheels are well known as excellent and it would certainly be a shame if he stops offering them but anyone who makes industrial contact wheels should be able to supply whatever wheel you need.

This company Linden in Solingen can supply just about anything: http://www.ch-linden.de/maschinen.html Their website isn't yet in German but their catalog is or if you write them in english and they understand.

It's been my understanding that Bertie Rietveld (http://www.batavia.co.za/Surface Grinder.htm) was the only source for the proper wheels to convert a grinder to belts.
I just recently learned that he is no longer offering these. He suggested that Pop's Knife Supply had the last of them.
Just a heads up that you might need to act quickly if want to make the change.

Bader makes them. The shaft for many surface grinders is a different size than most other applications for a contact wheel. Bader can custom make what you need.
