Here is a little trivia for you.
I have successfully cut .375 granite ( 3/8 )

Lets see who can get the closest to the correct wattage to cut this material.

Good Luck

100 watt light bulb and a rotary grinder

Of course done only at night.

Somewhere between 60 and 2200 would be correct . But let's see if we can narrow it down just a tad more...LOL

I maintain a PRC 1800w where I work. I'd guess about 875w.

I would guess 1650 watts with extreme air pressure.

Hmmmmm, You don't have a family named Watts working for you do you?:rolleyes:

In my quick internet search for answers I came across this sight, it's worth a glance.

Ok guys here's the answer.

It took 2100 watts at 50 IPS with 80 PSI of assist air using a 7.5" focal lens to cut the granite with a clean edge. The edge looks almost as good as when they use a saw to cut it.

Heres another thing we tried the other day:
Took a 2" x 2" x 10" block with a wood bolt centerd on both ends and attached it to a drill and laid it under the nozzle started the drill and fired the PRC up and cut a turned leg. Not real good at it yet but I think I might build a rotary attachment and give it a shot who knows.

Well I'm off to see what else I might throw under the nozzle.

Thanks for playing,

Will
