Tips for cutting round pipe/tubing square?

[Hoggslayer]

Try and cut it crooked and then it will cut straightish.

If you have to use a porta band mark the four sides and place in vise. Cut the line only. Rotate piece in vise to next line and repeat. A chop saw is best. Don’t force it through the cut cause the blade will flex and cut crooked.

well if you can buy either a chop saw or a smaller real band saw if you don’t want to and you have a miter saw for wood you could get a diablo metal blade and go slow with lots of wd40 spraying on it to cut quite a few pieces before it dulls
you could maybe do that in a regular skil saw too
now i’d only do that if it’s fairly thin wall
or take some thin cardboard cut a nice parallel strip and then wrap it around your pipe line it up square and mark your pipe then use the portaband to slowly cut around the pipe carefully to stay on line then grind it would be the cheapest way

If you want to saddle the round tubing where one piece will but up against another, buy you a whole saw the same size as the tubing. You drill a hole through the middle of the tubing and then use the hole saw to cut through the tubing and you will end up with a saddle that will fit nicely against another piece of tubing. I did this with aluminum pipe to build the stand offs for the T Top for my boat, it turned out good.

Mark your square tubing all the way around all 4 sides with a square. Cut a line all the way around all 4 sides with a cut off blade. Your portaband blade will follow this and not walk out of square. For pipe the same thing. Mark it with a wrap a round and cut a line with a cut off wheel. The blade of the portaband will stay in the groove and cut straight.

Duct tape /or blue painters tape work great for Mark....A piece of cardboard or Poster board with a straight edge wrapped around and squared up will give you a good making spot just add to HS78

The way I cut a piece of tubing so it is square on the end, is to get masking tape or duct tape and wrap it around the tubing where I want to cut. Then cut along the edge of the tape. I have done it a lot so I am pretty good at getting the tape on the tubing so it's square on the pipe. Then I used a angle grinder, with a cut off wheel to cut the tubing. On the tape, use a wide roll of tape, it's a lot easier to get square on the tubing, than the narrow masking tape. The wide rolls of tape it will be obvious when you start getting out of square with the tubing, and or if you bend the tape, left or right, it will wrinkle.

Another thing I have done on many occasions, when building intercooler tubing, I will often use a piece of precut silicone hose coupler, slid over the tubing I am cutting at a guide. That idea has resulted in me using more rigid, harder hose, as a guide at times. Not knowing what size tubing you are using, I would guess around 1 1/4" to 1 1/2". You might be able to find some hose in that size, but it has to be cut perfectly square on at least one end.

Now making a notched joint to but two pieces of round tubing together, which I would think you would need to do. I have a tubing notcher. It's basically a jig, that you can change the angle of. They you put a bi metal hole saw blade in, then use a drill and cut through the tubing. There are cheap tubing notchers, that work ok, and there are better ones that definitely work better. I would really think you would be using a tubing notcher to notch the tubing so you can butt the end of one piece of tubing up to the side of another, at whatever angle.

Evolution chop saw will do everything you need.

This is the correct answer!

Metabo. End discussion!!!

[roguefab30]

But why can't you make the square cut? That model of tool should be able to make a square cut if you know how to use it well

Dewalt or makita chop-saw for square tubing, with a quality blade. Metabo, dewalt xp ect.

Tubing notcher and a good set of metal hole saws for round tubing and a 1/2 drill.

You should look at tubing notchers. They work great, when you are cutting round tubing to weld to round tubing.

Most of the time I cut square tubing, I just use a angle grinder, with cut off wheels. I mark the cuts, then follow the lines. Also to cut a very square cut on round tubing and probably work on square tubing, is get some 2" wide masking tape and wrap it around the tubing, making sure, you do not bend the tape, so no wrinkles. The wider the tape, the easier it is to make sure it's square with the tubing. The use a angle grinder and follow along the edge of the tape, with the cut off wheel.

Said above, use a wrap around to mark pipe.
