Tubing roller

[dodgedifferent2]

I am always creating something for another project.
I am working on a 1931 model A hot rod.with a 331 chrysler hemi.
Nobody makes a trans adapter for the extended bell hemi to a chrysler a833 4 speed trans.
So I have to make my own adapter.
I need to roll 2 inch wide 1/4 thick bar in a 14" circle.

So I decided to build a tubing roller. I originally planned to drive it with a hydraulic motor and anticipated rolling 2" square tube 1/4 wall.
Slowly machining dies I want. Started with 2" square. I am working on 2.5" exhaust pipe dies (unlikely to work)
Need to make a few other dies but that will come with time.

That looks awesome

Be interesting to watch the final results as 1/4" tube is going to be pretty hard to bend. Might have to add some heat.
Keep us posted.

The hydraulic motor is a good idea, power demand goes up on thicker walled material.

Nice job. One of the fab tools I'd like to build at some point.

 

[BaitMaster]

Great job.

 

[Chris Cramer]

That makes sense, just the same idea as a hydraulic press with the use of three round dies.

Keep experimenting.
I wanted to develop roll forming for making corrugated HDPE pipe years ago.
The pipe mould shapes were to be made from extruded aluminum and fitted with roll formed sections to suit the corrugation profile.
Higginson Inc in Hamilton used to deal in lots of roll forming components.
Keep the updates coming.

Rolled some heavy wall 1.75 tube.
Also made two 1/2 square bar circles. Planning to make the Olympic rings.

See it works ;-)

Looks good.
You must have removed the ‘clamped‘ sections at the ends before you fused them together.

That's very cool. Great build!

Well done man.

What is the power tool for in this? feeding? and what kind of power tool is it ?

How did you make those dies? let's see some more details. Are there bearings in the dies? Great project.

It is a pipe threader. I got a cheap Amazon one. It drives the top roller instead of human power

I am a machinist by day so I created them on the lathe. Yes there are bearings in the dies

Maybe like this. That is a good idea. 22rpm. loads of torque I would assume.

looks good!

I'm always amazed at these impressive projects. Wow! Nice job.
