I wanna see the saw go!

It is relatively slow to cut, (perhaps 10 to 30 sq ft/ hour, depending on power and blade size) and requires patience to keep the applied loads at the right level...

• ##### that sounds fast to me?(3+ / 0-)

Am i missing something... sawing 10-30 sq/ft hour will zip through this thing in seconds?

figuring out what sq ft/hour means when it's cutting a straight line.

the way I do when cutting wood.

Imagine you're cutting a single pipe. After the cut is over, you would look down and see a circle with a given inside and outside diameter. The area of metal you just cut is that measure.

So lets say we have a single-walled pipe 20" in diameter which is 1" thick. The cross section area of the pipe about the outside diameter is 314 sq in. The cross section area of the pipe about the inside diameter (the hollow part) is 254 sq in. The cutting area is 314-254 = 60 sq in. or about 1/2 sq ft. At 10 sq ft/hr it would cut through in about 3 minutes.

Maybe my expectations are too high. This is like watching the minute hand on a clock.

a steel pipe. Keep in mind this wire is not as good as the one they will be using.

The rates given appear to be those achieved cutting limestone.
