the surface of a new Norton often needs to be lapped away
but the improvement was real for me. The advice also made
sense the more I considered how a resin bonded hone might be made.
Take a jar of resin add a lot of super classified abrasive, mix very
very well, pour or extrude into a mold, cure the resin in an oven.

As anyone that has made a cake, candy or tried to cast bugs
and shells in plastic knows "bubbles are possible".

I'm pretty sure they wouldn't be using a resin process for a stone like this. Resinoid abrasives are usually found in thin, reinforced metal cutting wheels or thick walled cups using very coarse abrasives. These are usually identifiable as resin based wheels turn dark brown/black after the oven, regardless of the color of the abrasive grain.

If anything, it would be a vitrified product, where the finished prdict has a color closer to that of the raw abrasive grain.

Oxychloride and Latex based wheels will have a more whitish to greyish blue tinge from the bonding agents.


Now I'm really going on memory here. 20 years ago, I worked in a grinding wheel factory for 3 summers (student work). Learned a lot about it at the time.

We did resinoid, vitrifed, oxychloride monster wheels as well as latex knife grinding wheels.
