Try to get the right angle cut

I made a tie station for a friends horses and I did not have to extra pipe to spare to keep trying to get the right angle for a saddle to have the top pipe to sit in... The pipe I was using was between 2 1/4 - 2 3/8 OD gas well pullout pipe.

I do plan on doing more and I would like to make it tighter so I do not have to fill in large gaps.

I did cut them down with my cheep HF band saw and set it at 22 deg. and off setting it leaving about 1/4" at the end. I hope you know what I am saying.

It worked to a point, just had a good size gap to fill.

When we were doing livestock pens we were using 3" gas well pipe and I know the cuts were at 22 deg. that is why I started there.

Is there a different angle for different size pipes?

Thanks for any input Don D.

Don,

If I understand you right, you're trying to have two pipes welded together in a "T" joint. And, the straight bandsaw cuts leave large gaps between the curved wall and the straight end of the cut pipe. If this is the case, the shape you need on the top of the vertical pipe is called a "fishmouth". There are two free computer programs out there, Winmiter and Tubemiter, that produce a paper template for creating a fishmouth on a pipe or tube. Enter the sizes of the two pipes, and the angle at which they meet. Print out the result and tape it around the pipe. Then cut the pipe along the template line. I work mostly with thin wall EMT, so usually just use a right-angle grinder to remuve all the metal up to the curved line on the template. There is almost no gap when the pipes are joined.

If this not the case.....never mind!

Don, I was going to suggest getting a pipe notcher from HF but I see that they only handle a max 2" OD pipe. That's not going to be big enough. There are various types of notchers that will handle the size pipe that you are using but they are quite expensive. The only other idea that I have is to cut the angle like you are doing and then grind a notch to make the joint tighter. It's a lot of work but the end result is worth it.

Good luck, Capt Ron

Thanks guys for responding. I think I will try Ken's idea with the software. Forget the grinding, this pipe is 3/16 - 1/4" thick. I will trace it on the pipe and line up the angle. By using the band saw it does leave a beveled cut so I do have to grind so much.

If I did not care about appearance I would torch it down and grind. Oh, how I wish I could justify a plasma cutter at this time... (give me time, more projects are coming up)

Thanks again guys. any other good Ideas still be sent in...
