A whole bunch of years ago, the shop I was working in purchased a small floor standing grinder that had a 90deg table positioned over the wheelin such a way that as we sawed square stock to keystock length, we simply slid the keystock over the table which deburred and put a specific sized 45deg chamfer on the key. It was quick n easy, the chamfers were uniform, and even me of little brain could operate it successfully. The table was adjustable at lease from 45 to 30 deg's, because I remember using both those settings. Something like that would sure come in handy at the shop I'm in now, but as I ask around about this product everybody thinks I'm nuts. Well they may be partly right, but I'm sure about the grinder. If anyone knows about a product like this, I would greatly appreciate any info you would be able to share. Thanks, K.
