@zander I will try and make a video on my next attempt. I just built a work bench 4ft x 8ft x 3/4 ply. I am hoping that will be a stable enough surface.
It may be a few weeks though.
Look forward to hearing any feed-back from my pics and/or video.

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.
