Can you laser cut square tube?
I've made a chassis brace for my car, which works nicely, but there's lots of fiddly cutting and welding. Members of the owners club want
me to make some for them, so I was thinking, can you get RHS tube laser cut? It would save me a job, since someone else is paying.

pretty sure waterjet can, andyw7de's got a little cabinet in his place full of stuff he's cut in half. mobile phones and their chargers
for example, a perfect clean cut the whole way through.
laser might be able to, but i don't know how it would do when it gets to the vertical side of the tube

You certainly can but you need one of these or something similiar, I've seen tube done on a conventional laser by accurate placement on a guide
plate which is then cut normally, only works in one plane really and if the cutting stays away from edges

You have no idea how much I want that machine. Given how that one worked, I guess the laser wouldn't cut through top and bottom in one sweep.

laser disperses after the cut , ive cut t45 tube for malcolm wilson in past life .
im pretty sure you can do square tube , but the torch head would need to move up and down with the workpiece as it rotates , which would probably
mean a dedicated tube laser , not just a laser with a tube cutting attatchment .

No kidding! You could make some very intricate joints with something like that. Being a diabetic I wonder if I could sell my pancreas for one of
those, it doesn't work anyway....
I'm not scared!!! I'm just marking my territory.

square tube now...simples

Road Runner Racing's SR2 has it's chassis and wishbone tubes laser cut just like this. It's is quite expensive for a single
chassis/wishbone set so you have to order in batches to reduce the cost per set. The chassis build time time is reduced significantly as each tube
just drops into the jig straight out of the box from the laser cutters
