    Re: Grinder tongue guard (for OSHA)

    Did you use your OSHA safety gauge and check the measurements?

    The grinder looks great.

    But it was for a school and teachers will have there say plus OSHA.

    The best news is you makes a lots of money with everyone thinking the best way.

    I do like you OSHA Drawing.

    Oh for sure......first thing I made was the double ended OSHA gauge and then tethered it to the machine....

    Wait...yeah that didn't happen

    I've never seen a bench grinder wheel shatter (not when it's on the machine, anyway ). I know people who've had grinding wheels on angle grinders explode, though.

    Those guards are nice, real nice, and you're correct, they're worthless, I don't remember what the clearance spec is but 1/4" seems to come to mind, they somehow fell off of my 2 home grinders, and you're 100% correct about their quality & cheap tin, they wouldn't stop or even slow down a serious wheel disintegration. Good job on your design.

    We did get trained a bit after my incident though. Was banned from grinding Aluminum tools on the grinder stones. 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. I'll take it as good advice not to use aluminum on any bench grinder stone.

    That’s interesting (and scary). Have to remember that!

    I heard about that one time, many years ago. Never saw the aluminum actually explode a wheel though.

    Last week some students ground aluminum on the large grinder.
    The aluminum did get very stuck to the wheel and caused steel to bounce when ground.

    Using the wheel dresser cleaned it right up. Grinding on steel did not - I thought it would. <shrug>

    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.

    Not a bench grinder, but here's a picture that showed up on another forum of a guy who got hit with an exploding angle grinder disc. I had another picture of his hand right after the cut with it laid wide open...didn't save it.

    My oldest brother Bill was a machinist by trade and he told me it was common knowledge in the trade to never use aluminum on bench grinders. Your explanation makes perfect sense.

    Re: Grinder tongue guard (for OSHA)

    You have to grind steel to remove the aluminum from the stone

    Or it will though chucks of aluminum at you .

    Much easier and faster to use a stone dresser.
    Cleans it right up and should eliminate the problem of heating up the aluminum to an expansion point that the wheel can't handle.

    Broken carbide bits work for dressing wheels. You DO NOT want to breath carbide dust, though.

    I do a LOT of **** that I shouldn't, though.

    1/4" huh? Guess I'm a little out of spec. I guess I do have the tongue guards, they're just such cheap junk I never really thought of them as "guards". Might be time for some new wheels too...

    If ya think OSHA is nutz! They aint nothing compared to MSHA, they cover the Mining industry, 2-4 surprise visits per year, your not allowed to tell other miners the the inspector is on site, but we have program for that! LOL. A MASHA inspector will fine the company of individual contractor just to justify his existence. Any time one shows up, the contractors roll up and take a day or two off. Basically a government agency that fines you to make you safe! LMMFAO
    We've done so much, for so long, with so little. Were now qualified to do anything with nothing !

    Since the cancer diagnosis, I'm using an N95 for all grinding, and welding. Didn't use any protection for 20yrs. Not saying that these particular hazards caused the cancer, considering I also smoke..................but a combination of the welding hazards, and smoking, could have been the trigger. I'll never know, but I figure I'll try to cut out at least one hazard, and cut back very seriously on the other.

    The greatest effect I've seen..........no more hacking up crap, or blowing my nose, and having it come out black. That mask made a huge difference when grinding/welding

    Assuming you're still smoking:

    I'm being 100% serious - start vaping.

    You can get pretty much any type of "vape juice" you want, any kind of nicotine concentration you want (anything from 0% all the way up to dang near lethal), flavor, even the "throat feel" (how harsh it is).

    Hell, if you want you can vape THC and CBD.

    I'd ignore the ads on TV about vaping being super dangerous. It's a load of crap. Supposed to deter teens from starting.

    WHOLE lot better than smoking tobacco at any rate.
