I am getting ready to form an exhaust system for a Landrover project of
mine, I have taught myself TIG to a standard that should stop the thing
falling apart, but I am facing some nasty bending problems.
Are there any relatively simple bending methods for 2-3" thin walled
(1/16) tube that can be used in a small shop ? I figure that sand
filling won't work on tubes of this scale.
I suppose I could cut and shut the tube, but its not as neat as radiused
bends.
Any advice gratefully received, and apologies if this is too OT for the
group.

Bending thin wall tube to a sharp radius is an art form even with top
grade production equipment. For a one off project, I'd suggest using a
vendor of stock bends. Cut and weld. My local supplier of these is
https://www.headersbyed.com/ There are quite few others, especially in
NASCAR country.

I am in the UK ! Where IS NASCAR country, out of interest ?
Sources of header parts are a lot thinner on the ground here.

Actually, the source I mentioned is a distributor, buys bends made to
his specs in quantities of a hundred or so, sell them by the one or two.
I used to supply to him when I was active in that industry. Your best
bet is to find a small bending shop using "draw benders with mandrels"
Checking around for "tube fabricators" is another search term.
See if you can design your headers using a single diameter tube with a
common bend radius.
I think of NASCAR country as centered in Georgia, US. There are
literally dozens of shops building NASCAR machines, dragsters, etc as
well as the supplier base like the tubing benders.

Please log in for more thread options The center of NASCAR is Mooresville, North Carolina. The majority of the
teams and suppliers have their shops there. It is a great place to visit as
most of the shops invite visitors, and it is a real thrill to hear the
engines being dyno-tested as you drive by the beautiful, huge facilities.
NASCAR country is the whole USA, in my opinion. And I am not really much of
a fan!
