I use a Grizzly 10 inch (T10010 I think..) wet grinder to sharpen my tools. It’s a barebones machine which approximates similar tools from tormek and jet, and I’ve found its performance just fine. As I get better and better at using my edge tools, I’ve needed to get better at sharpening them, so I’ve invested some time in getting my rig up to final form. Here are some things I’ve learned:
—It’s worth it to invest in a jig to hold your chisel/iron exactly 90 degrees to the stone.
—Conversely, I’ve found my eyes are just fine for finding the right angle to put a chisel/iron into said jig to match the existing bevel.
—... but if the face of your stone is not perfectly parallel with the guide arm of the grinder, you’re out of luck, and you’ll be grinding angles and parallelograms into your tools.
Enter this jig: it ensues that your Tormek/Grizzly/Jet stone is perfectly parallel to the guide rod on your sharpener. To true the stone to the guide arm it just takes a minute or so: 30 seconds for rough surface which will remove steel quickly, or 90 seconds if you want a fine finish. Works perfectly and it’s super easy.
Along the way I’ve learned two tools which dont do the job:
—A “T” shaped diamond dressing tool. Grinds the stone, but it’s essentially impossible to keep it square… at which point you’re doing a lot of freehand work—just to get inferior results.
—A “dressing stone” ... the one I have was sold with the features of ‘leveling and dressing a grinding stone’ ... turns out it doesn’t level the stone, but it DOES dress it. You use this stone not to level the wheel, but to change the surface of the wheel from coarse to fine (and back again). Who knew?
I hope that helps…
