I can rough out a shape on the pedestal grinders, then finish the edges easily and accurately on the Baldor carbide grinder. After cleanup, new switch, and repaint, this grinder works well. So I bought a Baldor carbide grinder that was ugly, and ran only in forward. But bit grinding still takes to much of my shop time. After cleaning up and adding new wheels, Norton coarse and med norton general purpose, and a white J cmpnd 46 grit exclusively for grinding HSS, The better rests were an improvement. They are controlled by a VFD so I drop the surface speed of the wheels to approx surface speed of a 6" wheel. ![]() ![]() ![]() So I got a pair of 8" older US made 3 phase grinders for cheap, I mean like $25 cheap for both. Just don't dunk it in water to cool it, that shocks and micro-cracks the cutter bit. And that it didn't matter if the bit discolored during grinding. Subsequent, through the various online forums I realized I needed to get grinders w/ better rests and quality wheels. I don't do it often, and when I did, it would take too long. Being a homeshop guy it would take me forever to get a bit ground right. ![]() I built a table I could add/remove as needed, and it helped. I have always used a cheesy underpowered taiwan grinder and the crappy wheels, and worthless POS rests it came with.
