Technical 3/8 Aluminum Tubing

Looking for some ideas on how to straighten a coil of tubing...3/16 1/4 3/8...I know you can get some tools for a few hundred dollars...maybe 150...Any homemade ideas out there...Any tips.

Thank You

 

drill a hole the appropriate size in a block of wood and pull it through

 

I roll it on a flat surface

 

Yup.

If you are doing this often, you can do what I did. I got a block of Delrin scrap, and drilled it slightly oversized for all of the diameters of tubing I use.

$5+time.

 

Short pieces roll em out in a piece of angle iron, long pieces stretch em just till they straighten with a come-a-long you will only lose about 6" if you clamp both flattened ends with locking pliers.

 

They make these in several sizes. Got mine at Eastwoods, works pretty slick!

Seal up one end and attach the other to about 300 lbs of air pressure.....

 

One of those things on the list to fab up.

 

That is awesome...where did you find the rollers...or pulleys....?

 

Sorry, didn't mean to impress anyone! Pic grabbed from the web. A design I intend to copy for myself. Steel rollers like that are often used in industrial/commercial machines.
