The project looks great... But I must be missing something. Wasn't your ram hard mounted in your main drawing? As it is now in the finished pics, it is floating just like if you were to buy the hydro set up for that bender. If I missed interpreted the main drawing I am sorry, still a bad ass build up. As for I bought the enerpac ram and treadle, I am lazy

at first I thought it was hard mounted too, but it floats like the conversion does. This is a nice setup and I like how it's laid out.

Na it was drawn with the ram floating and the main arms fixed. It's just more difficult to see in the drawings because I changed the view angle and there's no stand drawn in.

Thanks for the complements!

What exactly is a trunnion mounted cylinder, and what would the benifits be. Thanks .

Trunnions are two round pivot points welded to the outside of the cylinder, 180 degress apart. So forces act about the centroid of the ram, and are not offset (eccentric) creating bending of the ram and cylinder (not good).

ok i know this is a very old thread but im in the process of doing this with my bender. the cylinder is quite short so my question is what would give more stroke the op design that pivots as it bends or the style on post 9 where the cylinder mount is bolted to the bender? i tend to think the OP's design would allow for the bender to travel move with less cylinder stroke?

is there any advantage or disadvantage to either design?
