I purchased a slow speed grinder from Woodcraft a few months back and have been using it to sharpen my chisels freehand. I was pretty unsuccessful so I jumped on the Rockler Wolverine sale last month. Today I finally got it setup and ran into a problem.
First, let me describe the setup. I need to be able to move the grinder so that I can make room for my sanding pads (micromesh) - I like to lay them all out on a towel for them to dry. I took a piece of MDF large enough to mount the grinder and the Wolverine base pieces and mounted the Wolv. base pieces along with a riser board that the grinder sits on. I didn't mount the grinder to the board because I wasn't sure what kind of bolts would work. In the past the grinder has been fine without being mount, so I figured it wouldn't be a problem.
Well, I sharpened one of my gouges and it worked great. When I attempted to sharpen the next gouge (a roughing gouge, I think - it looks like the second to the last gouge shown on the gouge page at www.robert-sorby.co.uk) and all of a sudden I heard a loud clank, the tool jumped back in my hand, the grinder jumped back about 8 inches and my finger turned red and started aching. The Wolverine tool rest (the small one, not the long one) also got bumped forward and started sparking. Wow - that really scared me. I ran over and unplugged the machine - I was too scared to turn it off using the power switch.
Anyways, I'm not sure what happened - something must have caught, although I'm not sure why. So, how do I prevent this in the future? I'm guessing that I need to mount the grinder to the board and then clamp the board to my table. Should that be enough? Also, what should I use to mount the grinder to the board? I want the whole system to be movable, so I can't mount it with a bolt and nut, since the nut would be protruding from the bottom of the board. Any ideas?
Thanks! (and I'm happy to still be alive! My finger swelled up a bunch for a few hours, but it's fine now)
