Well, in my long list of repairs for the school, this grinder got written down for lacking the tongue guard (stupid guard).I didn't like the ones I found for sale, tin junk - and like the original on another grinder, they left a large opening (at the top) as they get adjusted down.So really, they don't do the job OSHA requires, but are considered a valid guard just because they are in place.
I decided to make a rolled design that is never in the way of a proper sight-line. (some of the replacements were straight and blocked some vision)I cut wood templates to the correct radii for the inner and outer shoe and rolled to match.(they can't be the same radius)I did the same for the radius on the mount.
The roller leaves very deep marks, but it doesn't slip
I milled the slots before rolling.
Made t-nuts so I only need one wrench to adjust (so lazy...)

Reply:I was fine my OSHA for no TP in bathroom. Had 2 guys running a 400 ton press break and they both had head colds so took out and set at press break. They both new where the TP was sitting. OSHA was not worried about paper cuts in butt or fingers in the break dies.FYI the fine in 1989 was $2,500 for no TP in bathroom Dave

Reply:Shame that people are so dumb these days that you've gotta put a guard on the grinder to keep them from licking the wheel. I bet it would HURT with that wire wheel!
I don't have guards on my go-to bench grinder. They are DANGEROUS if you use a wire wheel or a buffing wheel. Stuff gets sucked in, spun around in the guard, then flies back at you. I took the tool rests off, too. I just free hand sharpen my twist drills. Works fine.Sent from my Lincoln Buzzbox using Tapatalk
Reply:Nice job Dave but GD, what a waste of time. Next you'll have to leave it unplugged and put a pull cord on the unused wheel to get it to rotate. Least that way they won't get both hands in there. Crap, when i went to trade school (shortly after they invented electricity) the instructor took the side cover off so we could use the side of the wheel..........Mike

I've never seen it and thank God but apparently Aluminum will flow into the stone and cause it to be out of balance and or cause it to explode.

Edit: just remembered - the inspector told us that the aluminum gets forced into the wheel, and then when ground later the aluminum can heat up and expand, cracking the wheel.Thus, fragmentation and blowing up.

Basically a government agency that fines you to make you safe! LMMFAOWe've done so much, for so long, with so little. Were now qualified to do anything with nothing !
