Chainsaw Repair

I have been trying the 'resinoid' grinding wheels recently, and comparing them to the standard 'vitrified' wheels (Oregon, Tecomec, Molemab, etc.) on my Oregon 511A grinder, based on some comments posted by others.

The resinoid wheels look like masonry or steel wheels used in cut off saws, angle grinders, etc.  The only ones I have found for this grinder are TOTAL brand wheels (TL64-R and TL66-R), which I ordered through a local shop from Tilton.  Cost was about the same as conventional wheels ($15-$20 each).   Also available on line from sharpchain.com.  Some resinoid wheels are, apparently, also available for Silvey grinders.

I tried them on several .325 and 3/8 STIHL chains.  My initial impressions were positive:
- much less likely to 'burn' a cutter, although, I was able to do this intentionally on some scrap chain;
- left less of a burr on the outside side plate of Left hand cutters, using a non-reversable grinder (not sure why, exactly);
- leaves an acceptable finish on the cutters, although, maybe not as smooth as the pink, vitrified wheels I was using;
- makes more dust.  I try to grind out doors, or in a garage with the door open, but this could be an issue in a small shop;
- has that same smell as the cut off wheels mentioned above.

I would encourage anyone having problems or concerns with 'burning' or 'bluing' cutters to try these - could be a low cost solution.
