Always 3 teeth minimum engaged (for a quarter inch this would be around 12 tpi) Less (coarse blade) the blade will want to jump all around, too many more (fine blade) the chips won't be able to shed fast enough and you'll heat things up real fast...

Thanks guys that’s a big help

I’ll be back

That's going to be some rough noisy work. See if you can get a local fab shop to shear or burn your parts.

tsb I wasn’t going to get into it here cause I already have posts in another of my threads

But

I’m actually looking at adding load doors on both sides of the combustion chamber of my Frankenstove baseburner

So, looking to make openings in the side walls which are actually 3/16”

If the stove is not in a living area, I would use a hand grinder and a green wheel.

Good points + use cutting oil or, in a pinch, WD40 .. I'd cut with my band saw myself..maybe no have

In my opinion one of the best ways to cut 1/4 inch steel is with a cut off wheel. I wouldn't waste my time with a 4 inch grinder. Not that long ago I migrated to a 7" grinder and it makes all the difference in the world. If you want a straight line, clamp another piece of steel where you want to cut and use it as a guide. Reciprocating saw in my opinion is a terrible choice for cutting metal. I have a brother that has cut lots of steel with his Bosch jig saw.

Just use the 'score and snap' method.

Stove is in the living room

Already passed on the plasma cutter idea, to far from 220 and big air compressor, not to mention sparks near carpet

Tending toward the jig saw option, tooth count should be the same

Here’s a pic of the door and frame for reference

Will be making an opening on each of the sidewalls and bolting complete frames and doors on

Pretty easy project once the process is decided on
