sharpening grinder teeth?

[treeeguy]

Does anyone do this? I've got the yellow jacket teeth on a 252 and have to keep the teeth pretty sharp to keep productivity going. Whats involved in sharpening slightly dull used teeth?

You need to do the steel with a regulat grinding wheel and the carbide with a green wheel. The green wheels dont last long and the dust is super bad for you. This is the worst part of the bizz as far as Maint goes. I look forward to selling my stumpgrinder.

Get a decent breather. I picked one up at Lowes or HD for about $25. With a little practice you can reasonably restore the edge to those YJ teeth 2 times with the green wheel before the tooth should be chucked. It doesn't take that long. You can make a portable bench out of saw horses and do it outside. I've been doing it in a shed on a bench mounted grinder and I just clean the area with a shop vac afterwards.

We did but eventually just sent them out and had them done. A matter of better use of the time.

Used to do it. No matter what breathing masks with specs or goggles i tried i'd still always get residue off the green wheel in my nose & eyes. Knowing how bad that stuff is worries me still years later...

We switched to Greenteeth, the rotatable round tipped ones.

You can turn to 3 new edges on the one tooth, then just chuck em out.
They can be sharpened but i felt i got my monies worth and that saving just a few more to suck in that rubbish wasn't worth it.

If you need to charge a bit more on your stumps to keep new teeth on it i think it's worth it.
