Tube bender
I am building a tube bender, according to the plans there is 3/4 inch gap each side of the die, with a 1 1/4" pivot pin not worried about bending but what about side to side movement? Should I tighten it up so less of a gap?

Re: Tube bender
This is a upright using a Hyd jack. I don't expect it to have a lot of side to side movement but with a gap it could be possible, Just want to know before welding it up.

Re: Tube bender
Are different dies different thicknesses?
Spacers maybe?
Pics might help

YEAH...PIcs.
I just got an email from Photobucket last night saying their site is all back up and working.
The bigger the space, the more likely to bend the shaft in between.
Whose plans are you using?

Re: Tube bender
I can get a tape and take some pics of my bender if that will help.

Re: Tube bender
IF you could, I have a total of 4" space with the Die leaves about 1 1/2 on each side. Here are some pics, don't want to weld it though I can put spacers on it later as the pivot bar is removable.cbeck wrote:I can get a tape and take some pics of my bender if that will help.

Re: Tube bender
I think you are good to go with the space between die and frame. The backing die is stationary and that will keep things lined up. It seems in this design that you would want the main die to be able to move a bit from side to side, this will allow it to line up with the stationary backing die. Just my 2 cents.

Re: Tube bender
You'll want to leave some space so that if you want to bend a larger diameter tube at a later time the die will fit in the bender.

Re: old member checking in.
Hope these help. The large part of the die has about 1/8" per side clearance between the arms and the small block is free floating with lots of pin exposed.

Re: Tube bender
I moved it over here, thanks for the info, I am probably going to put some spacers in it to keep side to side movement down. Thanks!

Re: Tube bender
a 1 inch pin can easily bend 1.5x.120 DOM with an inch or more unsupported on both sides. Mine has been doing it for years, although 90% of what I bend is .09 erw.
give a man a watch and he'll allways know what time it is. give him two and he can never be sure again.
Things are rarely just crazy enough to work, but they're frequently just crazy enough to fail hilariously.

Re: Tube bender
i did sleeve mine tho so it dosn't take as much force, but I don't always use the sleeves, they just slide on and more help avoid the die rocking than actually support it

Re: Tube bender
My pin is 1 1/4 but I will put a sleeve on like you did just to keep it centered. Thanks!
