I used the $80 HF air over oil ram as well and fabbed up my own swivel mount using scrap around the shop. Works great. Maybe an hour to fab up.

New member here. I don't currently have a bender, but I do have a design. This is a simple tool to bend 30mm X 2mm wall 4130 Chromoly.

Great site, thanks.

How well is i holding up? I plan on doing the same with a foot control but am still skeptical on HF rams. What material are you usually bending?

My setup is working great, don't have allot of miles on it yet but I don't for see any problems. There is some stuff from HF that is pure junk and some that is decent, I think the jacks fall in the latter category.

Just bending 1.75" .120 hrew at the moment. It doesn't load the jack much though seems there allot more power left.

That is a nice set up. I have teenage kids therefore can't afford anything like that right now. Like mentioned above I took the HF 8 ton air over oil route. Here is how I did it using scrap tube layting around from a tube fender build.

I may have to change that :/ Injured my knee pretty good earlier this year and when building a bumper the other day, I could hardly walk later after just 4 bends.

Manual over hydraulic power - ala 12 ton bottle jack... Its slow, mind-numbingly boring, but it gets the job done.

I paid quite a bit for mine but it didn't come with a steering wheel, is this the shifter?
