I have an old 7 1/2 inch ? ... standard size inch circular saw.

The metal cutting blades are more 'spensive than the cheap concrete cutting
blades, so I generally use the concrete cutting blades. Haven't seen much
difference on wear time.

I use hearing protection, eye protection and beware - lotsa hot sparkie
thingies.

Relatively wide kerf, and it works pretty fast.
Disc life is related to the amount of oomph you put into the cut.

YMMV

I have on old garden tractor that I took appart a couple months ago. I
wonder if there is a way to cut up the deck/frame etc in to 4" strips
for metal fabrication projects. I think it's 12 gauge steel. I have a
jig saw, air body saw, air cut-off saw, HF sawzall / portable bandsaw/
4x6 bandsaw / carbon arc torch / a few metal grinders from 4" to 9"
and a 7 1/4" circular saw with abrasive discs. I've used grinders
before and I think they are awkward, slow and would take forever,
I tried using carbon rod in a welder to melt steel and I though it was
too slow - I have a 140Amp AC/DC welder from Harbor Freight
Would I be ok with a bandsaw or is it too slow for cutting up thin
steel? I haven't used band saw before.
Would circular saw with abrasive disc work ok?

Basically I'm wonder how fast12 gauge metal can be cut (like feet per
minuter or hour) and if it's worthwhile given the cost of consumables.
Any info much appreciated

Thanks

Ross
