Tubing Roller question

[studysession]

Hi -

I am starting to build a tube frame for a go-cart and eventully want to also build motor cycle fromes etc.....

I bought this tubing roller - (without the stand)

Heavy duty tubing roller is designed for bending steel, copper, and aluminum tubing. Great for fabricating exhaust, roll bars, and more Bends tubing from 3/4" to 2" diameter Incrementally creates the bend for precise control Stand and square dies sold separately. Rollers diameter: 4"; Overall dimensions: 11-1/4" L x 24-1/2" W x 19-3/8" H Weight: 75.75 lbs.

I was playing with it and like it. But trying to figure out which is better - a roller or bender? Benders are much cheaper and it is tempting to return the rollwer for a bender instead.

Also - What tool is used for crimping the end of a tube so it can fit into another tube the same diameter? I do not want to use fittings. I want to crimp one end to fit into another tube and then weld them together. Not sure what tool is needed to crimp the ends like that.

Thanks -

Hi, If you're still wondering...It is called tube notching. To "notch" a tube. They sell some jigs where you can connect a hand drill and a hole saw (of the diameter of the tube you want to fit onto), clamp your tube and notch it at the desired angle. The cheapest I found go for about 150-200$
