Guys,
This comes up once a while and whilst looking up making a sheet metal bending brake thingy i came across this. He reconmends using a lathe to make a
couple of bits, but gives details and suggestions on how the same parts can be made in a pillar drill.

Love to hear somones results making this.

Looks like fun, I think the only issue will be if you want to bend thick wall tube, for say wishbones (not sure how thick thick is though he may say)
you might need better formers, i.e. solid steel..

Im going to make a manual version using the hydraulic dies and rollers. Itll look exactly the same when its finished, but with proper formers.

Basically the author is going aagainst convention by describing it as a pipe bending machine. Pipe (usually) means material for carrying fluids, and is usually measured buy its inside diameter, whereas tube is measured by its outside diameter and is structural
Those instructions are no good for you lot, it shows pictures of proper welding, not MIG
Mmmm, I have doubts about using a pillar drill to make the formers
but for anyone contemplating making steel formers on a lathe then
the pic below may help.
Turning the allen key moves the cutting tip in an arc. It works well.

Paul a really good idea. Can you show a detail pic showing how the tool is gripped in the bolt.
Many thanks

An M8 grub screw down the centre of the M12 allen screw does the trick John.

All is now clear Paul, thank you,

For a tube/pipe bender also have a look here:
Instructions
Drawings
It is a similar bender to the JD2 model III bender or the
Pro-Tools model 105 bender.
I believe you can also use the forms of these benders but you can also make your own forms. You could use a ball turning attachment on a lathe to
make one of these, for example this one: Ball turning attachment
