Today's bone-head move by yours truly:
I started making a jig for my carbide grinder. Simple enough. 6061 flat stock, and I milled a tang into the bottom that slides in the slot on the grinder table(s). Then I drilled a few holes in the top that serve as pivot points to grind different radius' on my scraper blades.
Then I thought I would add a couple of 30° slots in the jig up front, for grinding HSS V-threading lathe tools on the other side of the grinder. All was going well. I had one slot done and completed the first pass on the second slot. I stopped the mill to clean out all the chips before taking the final cut in the second slot. This was all done standing in front of, or to the right side of the mill as I normally do.
Then I moved to the left side of the mill to get a better look at the end of the slot, because the chips would get packed into the dead end and block my view of where the slot stopped. OK... everything is clean and has a clear path, cutter is set to the correct depth, and located away from the edge of the part. Turn on the machine and start cranking on the X-feed handle -- BAM!
Then I look up and see that as I was standing on the "wrong" side of the mill, I turned the power switch on with my "wrong" hand - the wrong way! (Reverse)
It's one of those days...
