This is my new toy and I had to make a mount for it because I got sick of it when it was mounted outside on the concrete slab.

I like this bender.
I did see a "hausfeld 4" that looked like it had its own racheting air cylinder for mucho $.
The handle and air hose? make this look air-hydrolic. I get the physics, but can't understand the air part that looks to be below the oil part? How do you keep the oil from bleeding with the air?
Last pix looked like threads on wear points, probably OK the way used here.
Bend On, Bend On

Yeah, the bender works pretty good for what it was designed for.
I was wondering about the positioning of the ram also. if you have more experience with such things would you recommend turning it the other way? And yes, it is air over hydraulic.
On the one pic with the mount you are correct about the threads. I was just testing different positions such as tilting the ram bottom down a little to see if it made any difference.

Bob,
The way the air-over-hydraulic system works is that the air goes into the top part of the cylinder (the one with square end plates) pushes a piston down which has hydraulic fluid under it. The hydraulic fluid gets pushed out a small opening and the fluid comes in under the piston if the larger cylinder. By forcing the hydraulic fluid out a small opening, the air pressure is multiplied and pushes the piston on the larger cylinder outward. The air and hydraulic fluid never meet each other so you never have a air bleeding.

looks good zach, I wish my ram would have come with a mount on the bottom of it like that. hopefully I'll get mine finished up this weekend and can post pics of how I mounted it.
my only concern about your ram mounting position is that it would seem you need more angle on the bender when the ram is pulled all the way in. this would require not mounting the ram hanging off the side of the tube but on top of the piece of tube. if you look on P4x4 a guy posted pics of how he mounted his. I'm pretty much duplicating what he did.
Edit: here's pics of the one I'm talking about:

Also, I just bought a garage door spring yesterday at HD and I will be mounting that on Saturday for the return activation. I feel that I have enough "feel" and control of the relieve valve to be able to feel the springback. I'll let you know how it comes out.

No, I was just using that end lowered to fill the ram. I am using it with the tabs of the ram on either side of the plate, if that makes sense. Basically, the ram is perfectly level.

Yeah, I was somewhat concerned about that, but it is 3/8" thick plate and after bending all day on Saturday both 1 1/4" and 1 3/4" .120 wall tube it did not show any deflection or bending AT ALL. I don't believe in major overkill when not warranted. To me, as long as something accomplishes what it was designed to do it can be as light as it can be.
