@nvdome Fascinating idea. I don't currently have a bender to try it myself, but I've used them before and what you are saying seems quite possible and quite intriguing.
Are the currant Bender tools you offer capable of bending 1 inch od square tubeing?
There's also: https://www.harborfreight.com/tubing-roller-99736.html
though I have some doubts on the quality.
One turn on the tension screw produces about a 12' diameter circle with 3/4" EMT
2 turns produces about 5' diameter.
You can produce a very small radius, less then 6" if need be.
It would but we dont' have 1" square dies. Now we only have 3/4" EMT (.93" round)
We'll have 1 3/8" round dies before too long.
