Cutting 2 inch plate

[mader656]

I've got some 2 inch plate to cut. About 10 feet of total cut. Torch or rent a demo saw and a bunch of cutting wheels?

I think you’d burn through a 14” or whatever they are blade in about 1-2” of cut.  I couldn’t torch 2”, but a guy who knows how, could right? I think I’d try the torch.

I use cutting wheel much less than I used to. That thick I would hate to use cutting wheel . Our demo saw is rarely used . Is this to scrap or make a snow plow for the Michigan ?

Any chance that a diamond edge cutting wheel would do. I have cut 2" hardened shaft with one and they wear really well but to be clear I don't know about using one for what you are doing. I used a 4" diamond to cut up a 10' steel flatbed last year along with a lot of other projects and that wheel is still alive it cost around 22 dollars the 14 " was 140 I think

Torch. And a pre-heater.  Check your tip size and think it through 

[bitty]

Clamp or tack on a piece of angle iron to use as a guide to cut straight. Extremely smooth movement and the correct tip size and pressure and it can look suprisingly good with a torch

Torch

No 3 tip and 70 psi oxygen, 10psi acet. and have at it. Preheat helps but I have cut it cold.

I bought a parts genie boom ($700) for the slew pump and a few other parts for my post driver 2.0 and the 5'x5' x2" plate I'll get pictures tomorrow It all rides on needs to loose weight and size.

If your gas axing off parts to lighten her up, and can dress up afterwards (you don’t need to weld to the cut) definitely use a torch.
There is a reason that after all these years and so many new processes and inventions it’s still in every shop

Upon further Googling I might be able to pull the whole 2 inch plate and bolt a one inch plate in its place that is shaped like a really need it.

Time will tell tomorrow

I have cut up to 7inch thick by hand,  it can be done with a steady hand and the right equipment.

I have a 6 X 12 X 2 steel block that I use as a bench block. It was obviously cut by a torch of some type. My guess is laser/plasma but ships armor was cut by gas torch.

i would use a straight edge. good no. 3 tip in torch set gauges at 50 psi oxy. 3 psi. acy.  keep the cone flame just off of steel plate. used to cut a lot of thick plate for motor bases. with a little practice and patience will be little to no slag to chip off and very little grinding to clean

Torch. Don't try to rush this, 2 inch plate cuts about a foot a minute, maybe a little less.

 use a big tip, and plenty of pressure. Starving a torch makes it easy to flash-back.

What in the world was that? Naval armor plating?

Correct tip size, correct pressure for said tip, and correct preheat.  It is just steel.  Thicker steel cuts easier than thinner steel once you get started.  There is just more “thermal mass” to it.

[mader656]

Upon further review I should not need to cut it, just cut the one inch plates off the 2 inch. 

 

Might as well save weight whenever i can

[mader656]

The 2 inch plate will make a nice work bench.

On a lime kiln the steel rings (tires) that the drum rotates on need to be replaced every 10 years or so we cut them into three parts and lift them off with a crane
