Was in the mindset I want it all and I want it now... had the funds so I bought it.
All that aside SWAG makes a set of brackets that center up the ram instead of swinging it offset... and the HF ram has a longer stroke than I have currently. But I haven't encountered any problems with my setup other than the size of my garage....
Thanks for the reply I'm to far into the build to start buying JD mounts etc I've got a pump which is man enough according to my figures to bend the tube providing I use a 3" ram at 55bar, I probably won't ever bend 2" × 1/4 wall tube though, I want to be able to transport the bender without taking a compressor etc.
The main reason I'm going hydraulic is I don't have the room to bolt the bender down anywhere so making it on wheels and jacking bolts to level up is the best option for me,
I also want to achieve a 90° bend without repinning etc,
I have done a few sums based on presuming that I mount the ram so it is right home when the arms are touching
I have allowed for 18" arm lengths but in reality may be shorter,
I have allowed 10° to take up pressure on pipe and 100° to be able to easily achieve 90° after spring back, so calculating it as a isosceles triangle it would be 18" arm length by 110° maximum angle which works out at approx
29.5" stroke length
Does this sound right to other people
