How much did it cost to make, total? How much time? Material?

Interested in selling copies of the plans?

x2!

That bender looks great! What size bolts did you use 1/2", 5/8", etc.? What size cross pins did you use?

I'm insterested as well. How much did you pay for the plans? If you don't want to sell them yourself, what seller lists those plans?

I just bought those plans off ebay. Looks great good job!

What size die did you buy? What degree die did you buy? 120* 180* 240*?

That is going to be my next project

If you would like to find them, just search ebay for tube bender. It is the heaver duty one listed.

If you can't find it. You can look here. tube bender

I don't think the guy sells dies.

Just the plans for the tube bender.

The plans use use a pro-tools die. square or round.

Seems like a whole lot of extra fab.

Why don't you guys just clone the protools 105 bender...thats what I did. It only cost $25 in surplus steel, arms are 5/8 thick.

The JD2 and Pro-Tools style only has to be bolted to the floor if you are using it manualy, if its hydro it doesnt need to be bolted to the floor...

I cut the arms out myself with a buddy, two benders were made. We did it using a gas hatchet, pedestal grinder and mill. It took about 18 man-hours, start to finish. So the total cost was $40 in surplus steel.

In the beginning I used the ratchet setup...but now it is manual hydro. The cylinder is something I got from gf's dad...it is hard to describe but imagine a 48" hydraulic hi-Lift jack. I'll try to find a pic.

I posted the arm plans a long time ago with the spacers and everything...do a search in Gen4x4 with my user name.

Are there any downsides to having it mounted that direction? It sure seems easier to get a long section of tube to rest vertical than it does when you are trying to get a long section to stay in plane mounted the regular way...

gents,

I just got my plans from www.gottrikes.com. They look first rate and very nice engineering job.

I've been looking for a bender to buy/build for a while now. Here's the reason I like this design the most:

1. not a "manual" bender. No bolting to the floor, or the room that it takes.

2. vertical design. with a pair of electronic levels, getting identical bends should be a snap.

3. uses common dies. Protools 105. any size up to 2." dia x .134" thick

4. portable - I'm adding wheels to mine so I can roll it anywhere!

5. $20 for a set of plans is a bargain!

The only down side (not for me) is you need a milling machine, fab skills, and welding skills. Or "friends with skills"

later,

Reflexx

milling machine? What needs to be "milled" ?

Looks like just holes drilled (I got a drill press) and welding (I got a welder)

So you know your holes are DNO, not just close enough....

Brandon,

I only said milling machine because some of the holes are near an edge and might drift. A drill press will work just fine, just make sure you use a center-drill and gradually step up the drill sizes.

I'm gonna bore the holes 'cuz I can.

Why not just go 3/4 and never look back. I have heard of poeple breaking the 5/8 ones right at the holes. All my steel was free and I got lucky and had mine milled for free also.

What tonnage ram is that? I like this idea, I can not afford full hydraulics right now but need the bender to not have be bolted to the ground. I have the Protools.

I just had another thought, on my protools the ram will be sitting horizontally instead of more up and down like in the pictures at the top of this thread. Will the HF ram have problems running in the horizontal postion?
