Making electric Roller Bender Part part 3/3

If you didn't see how I built this machine, you can do it here: https://www.youtube.com/playlist?list=PLtp0qX2WkOnWPX41pclLIcl4Sg3kbcE1b
After doing this test I deduced a couple of conclusions which can be helpful for you.
9RPM It's definitely too slow. I suppose 15 or 20RPM would be a better solution. If I find time someday, I'll change pulley's. It causes that bender will bend a material faster than now.
Wheels which hold material have to be tempered. I thought this process pass me by but I was wrong.
I'm going to give all axes to temper. It won't damage them moreover It'll give them a positive effect.

Advantages of this project:
A cylinder and a hydraulic pump: I'm content with this system and I suppose It's much better solution than a screw and nut.
Replacement of bearings in the middle part was accurate. A roller is much stiff than before.
A switch R-0-L holding in the hand turned out to be better option than mounted directly to the bender.

As you have seen, the largest material I bend is 30x30x2mm. Behind the camera I tried 30x30x3 and it worked, although it took a bit longer. I think that the 40x40x2mm profile is the maximum size that this machine can bear.

Some tools I used in this construction:
