    Re: Cutting wheels.

    Who here uses a resparater while grinding with a cut off wheel, flapper disk or grinding disk?

    I wear a 3m pink one whenever I grind. I rarely do much cutting other than breaking a weld here and there.

    Breathing stuff in is NOT good for you. And it’s definitey the last thing I need.

    I usually gauge the effectiveness of my respiratory protection by how much black garbage comes out of my nose in the shower afterwards.

    I wear a 3M green, had it for years. Have replaced filters twice. I don't use it all the time when I grind, about half the time. Maybe this post will remind me to use it more often.

    BTW, I'm especially careful to wear safety glasses, I find that to be the most dangerous when grinding...chips can even get under the lenses if you're not careful. Slag from stick welding is the worst for me when using a wire wheel. That slag flies everywhere when using the wire wheel.

    I have a couple of respirators but rarely use them. I should use them when using rattle can paint.

    Re: Cutting wheels.

    I'd rather be dipped in kerosene and thrown into a live volcano than cut metal for a project with a Sawzall. I have one and lotsa lotsa blades. I hope they rust away before I reach for it again. It's an OK thing for wood butchers and demo I suppose.
    When I wear a respirator , I normally wear a Resp-O-Rator (brand) I have the 3M pancake too with the 2091 pinks.Wear it a little for galvanized......something else I avoid like scorpions in my shoes.
    I'm blessed to be basically outside every day of the year.

    64-68 at night and 74-78 in the day. Every day.
    An occasional front comes in and I've seen 57 in the night or an odd hot August day when it gets to 85 or so
    This is with 1000 % humidity.
    Even plastic rusts

    I wear a respirator while welding and just leave it on when cutting or grinding.

    So not very hot bug gets pretty muggy like when I lived in Spring just north of Houston TX.

    Re: Cutting wheels.

    Delurking again...

    I use a regular circular saw and the Diablo blades. The dedicated steel saw would be much nicer since the guard completely covers the cut and contains almost all of the chips. I just suit up with a long sleeve shirt, welding cap, gloves, and full face shield. Don't push it too hard, and give the saw some cooling time for thicker cuts. I made a 48" cut on a 1/2" plate like this, where I learned the hard way about giving the saw some cooling time... Made 36" and it let the smoke out. (but I just need to get the armature turned smooth, to go with the new brushes)

    This is where a Harbor Freight circular saw would be handy too, so you don't take a chance on your good woodworking saw...

    When I use my saw to make longer cuts I use a straight edge and smear a light coat of cutting paste along the cut line.

    Re: Cutting wheels.

    I have had the best service from 3M Green Corps and Cubitron ceramic (2nd choice) wheels. Roughly $7.50 ea in small qty, but each outlasts 5 Norton Gemini/3M general purpose $2 wheels easily. I use maybe 2-300 per year on a 4" pneumatic right angle cutoff tool cutting about everything imaginable including titanium rebar(nasty tough). The 1/16th thick wheels have the best cut life to kerf ratio IMHO at that size.

    Quite a few recommendations for these slicers, I’ll pick some up on my next LWS trip. Been using 3/32” E6011 @ 150A after some practice it’s kind-of Ok. Lol requires some grinding but gets the job done.

    It's a beast. I'm trying to think of a complaint I have with it and honestly I can't come up with one.

    I use the smaller slack belt sander on the floor for deburring but the grizzly gets used to bevel tubing and flat stock all the time and with a fresh belt it absolutely eats metal.

    It is more than double the welding amperage of that rod, lol. I have been using them to cut steel plate with.

    Note:Only for practice steel, not anything project related.

    Re: Cutting wheels.

    I would buy my metal for the size coupons I wanted. Like 3/8" x 2" x 20ft and then cut off whatever length I desired.
    Doing it that way makes those coupons the cost of super expensive metal. Plus the time as well. Unless you would rather cut than weld.
    There is no good reason to waste a decent piece of plate by chopping it into little pieces....it's too hard to get to use for that IMO

    I would agree, but this is scrap steel plate, and it was free. Most of it has some spots that have been welded on, the pieces are around 8x8” or so. I’d rather be doing more welding than cutting, but like I said it was free, I just need an efficient and low budget way to cut it. Maybe this is one of those cases where it’s pick one, can’t have both. In other news, I’m becoming more proficient with my angle grinder.

    Re: Cutting wheels.

    Sometimes it cost you just as much to buy new metal for coupons than it does to burn through cut off disks and blades to end up with not as nice coupons.

    Yeah I need to head over to the local metal outlet store. I actually priced some 1/4” flat stock at the big box stores, and they really upcharge you. Very pricey.

    Re: Cutting wheels.

    I get most of my hobby steel at a ornamental iron supply. They have most of the flats and angles I normally use and some tubing. Only downside to the decent prices is they close noon on Saturday and closed on Sunday. So if I need steel after those times and I did not plan it out then I get ripped by the big box stores for less material
