We are having a discussion on another forum on cutting tube miters ( Birds Mouth) for joining/welding tube. I wanted to post this info here as it really works great.

There is a program called Tubemiter.exe that when you input your tube size, it will print out a template. You tape the template around the pipe and then cut the pipe to the template. Perfect fit, ready to weld.

Go to the following link and near the bottom is a program description with page print outs so you can see what its doing. You can also down load the program there. The program is FREE and will fit on a floppy so a old laptop in the shop or road would work well to have this with you.

Thanks very much, Paul and Bob! If there's one thing I love it's fabricating steel, but there's sure nothing wrong with making it easier!!!

Thanks for posting this Paul. I just used the program over the weekend to help in making a new exhaust system. I went from a too loud, out-the-back dual setup to a single 3" out behind the rear passenger wheel with a new muffler that's thankfully much quieter. Tubemiter was used to lay out the miter in the primary tubing into the three inch 'collector' at a 45 deg angle just fore of the muffler.

Thanks again,

Ken

Ken, your welcome. I am happy it worked so well for you. I use it a lot. In fact when I get time, I am going to make a bunch of different patterns out of FRG Glass board so they are handy. I use FRG Glass board for many templates that I cut with plasma. Works great. Now, my problem is getting the time ha ha

FRG Board is a fiber glass board 1/16" thick. Pebble finish on one side, mat finish on the reverse. Comes in 4x8 sheets for about $16 last time I bought it. Very good for templates you want to keep. Plasma Torch will not mess up the template edge.............if you use the Plasma right ha ha
