Thanks Dave! I like the way its turning out so far. Yes I am puting the HF air/hydraulic jack on it. That will hopefully get done next weekend, along with the wheels and something to level it on any surface.

Almost done.

Well I have it all mocked up and ready for some test bends then final welds and paint.




I am still trying to figure out the best way to connect the ram to the bending arm. Right know I just have it bolted through the end of the ram. I need to get some tube and give her a trial run. Thanks for all the help and if I copied somones design I hope you dont mind.
I also still need to put the wheels on it and leveling bolts.

I took a piece of 1.5" tube and put a groove in it to push on the sleeved bolt... that way the cylinder can be pushed back independantly from the bender arms...i never did get a spring installed, but this worked trick




Nice stand, get it welded up and get to bending

Has anyone built a bender stand for the rachet arm set up that didn't require bolting to the
Concrete floor
I don't want studs sticking out of the ground and I only have a small space so need to be
Able to move stand out the way to get cars in/out I was thinking of mounting on a heavy truck brake drum if this wasn't heavy enough then fill with concrete
I will be bending 1 1/2in tube 0.120" wall thickness
Any thoughts please??

Big brake drum even filled with concrete will not be heavy enough to not move when you pull the lever.
When i had mine mounted to the shop floor, i installed drop in anchors and removed the bolts when not in use. The anchors did fill occasionally with debris that had to be blown out.

Mount it to a pallet, you stand on the pallet and pull the handle, it works. I saw this setup at the OffRoad Expo one year and tried it out.

I had mine set up to bolt to the bed of my trailer for a while. It wasn't the most convenient, but it worked until I went hydro.

I have seen hitch receiver mounts. Make sure the tube won't hit your truck as you are bending.

I suggest a drop-in concrete anchor rather than a stud. It will sit flush once installed, leaving the floor flat. Bolt the bender down when you need it and remove when you don't. You can install them in multiple locations to give options depending on where the tube will be swinging around. Use a hammer drill, proper concrete bit, and clean the hole well before installing.

This is allot of value to these anchors in the ground for other uses.

You can build a plate to use it to secure multiple tools to the ground, a pot for chaining frames to the ground etc.v

I will be going the drop in threaded sleeve anchor i think that will work well add the infinate8 mounting plate I should be right. Any suggestions on distances away from objects for the stand I wanna try place it so I can hang the tail of the tube out the roller door(shop opening) also looking at the bender stand plans for the ratchet arm set up it says to make 760mm high or 30" in your language at a quick mock up isn't this miles to low? I would be thinking more 1000mm high floor to Rachet arm (40")
Any feed back or experiences?
Cheers guys

Guys, its so obvious!

Remember that thread showing how to build an electro magnet like the ones in the mag-brake?

Build one and set it in the floor. Roll the bender (or other tool bases)over the mag, boom!

I agree 76cm is way way too low. 100cm is a pretty good working height IMO. There's some good discussion on that topic in the thread below.

Bender Height - http://www.offroadfabnet.com/forums/showthread.php?t=5646

I visited Scootek's place many years ago and watched him use his bender, which is setup pretty high (52" per that thread). It actually worked rather well for bending manually because it was roughly chest height and lended itself to a boat-rowing body position. There was also tons of clearance under the bender for multi-plane bends. It did seem high for installing dies and loading the tube, but that's just speculation on my part.

A magnetic bender holder, sure that would work with a large enough electromagnet.

Maybe build the magnet into the bender base and sink a steel plate in the floor?

Cool idea, but thinking hydraulics might be cheaper and easier...
