Quick question about cutting tubing

[johnc]

Generally you do pie cuts for style or if you can't get a bend with the right CLR. They are a lot of work, with the most work on the inside trying to reduce turbulence.

love the pie cut look but you would think with all the flat angles inside would create turbulance that would inpede flow?

But as John stated above, you generally do this for style meaning you dont care about functionality/performance as much,

or you do it because you dont have a centerline radius die that will fit the tubing your working with.

Mark the steel tubing where you need it to be cut and lock it tightly in a vice. The tube should be immobile but not held so tightly as to dent the metal. Attach the torch's lines to its oxygen and acetylene tanks. Make sure the valves on the torch are shut tight, and then loosen the valves on the tanks to pressurize your torch's lines. The lines should fatten up and become more rigid when this happens. Loosen the valve on the torch to about half-way open. Hold the striker in your other hand and squeeze the wire handle. The piece of flint on the inside of the striker should kick up sparks and ignite the torch. Adjust the valve on the torch so that the flame narrows down and losses its smoky quality.

I don't think you want to be using cutting torches to cut the kind of tubing were talking about.

Yeah, not a good idea...
