When you weld the main pivot tabs onto the uprights; I would suggest going light on the welding until you see how the tube sets in the follower and die.

I had my tabs a little low or high (I forget) and the tube was no where near level. I had welded the piss out of the tabs and had to do a shit load of grinding to get them back off.

Thx for the pointer! I was going to weld the base, brace, and tack the uprights and check for function. Sound good?

Yes, it seems that the pivot tab location is very critical. If you get them a hair high or low, the straight piece of tube will tilt up or down when you put it in the bender. It doesn't have to be perfectly level, but mine was 15 or 20 degrees out of level.

You might want to put more than a "tack" on those tabs because they are holding a lot of weight. But just don't weld the shit out of them until you know that everything aligns up.

One other thing I did was to stick 5 or 6 pieces of 7/8" (I think that was the size) in the upright holes before I welded the up rights to the base.

There's a 25% off coupon that puts the air/ram at $68



There's also a 8/sheet 25% and a bunch of freebies on slickdeals:
Harbor Freight Coupon Thread 04-02-2009 - Slickdeals.net
Scroll down almost to the 3rd post.

This works out to a better deal than next month's ITC coupon:

I bought Franks plans, which were awesome. Then bought the harbor freight jack. Then things snow-balled and I ended up with this....only took me two years. Good thing I had another bender to use! Lol!

I bought the plans a while back, but now have forgot my password. I have the file saved on my computer. Can anyone give me a hint as to what the password should be, or is it just random?

Just Finished Mine

Just finished up my build of the gottrikes bender, I built style B.

I am using 1 and 5/8" and 1 and 1/4" die sets.

In the video and pics below, it is set up with the 1 and 5/8" die set and the tubing is .165" wall.

Very happy with it so far. Thank you to all who have contributed to this thread.

Here is a short video of the bender in action:

Just finished mine. Did not want to bend over to mess with tube/dies so I built mine on legs with locking casters.

For those of you using return springs...how are they working out. Do you have a part number for the springs you used?

For those of you who have built this, I am considering starting this build soon, likely the gottrikes model. Can anyone think of a reason to drill all holes if I only intend to run one die? I figure it will only serve to weaken the bender, dull more bits, and kill my drill press, and I only need one set on the base for slide block and one set on the swing arms for die, really. (Of course, still plenty of holes to mount ram, pivot point, etc etc)

Thanks for any input.

Once its all welded together it'd be a bitch to drill any more holes if you ever wanted a different die. Why only the one die size?

Slow rpm and use lube. Your drill should last a long while. Also learn to sharpen your own drills.

Honestly, because I'm cheap/broke, so won't likely spend the cash on additional dies. Really, it should be that it's for different radius bends, not different tubing sizes. The arms would be easy enough to redrill later, so maybe I should suck it up and drill the frame now. Not too bad going through " walls anyway, and can just drill the pilots for the "future expansion" holes.
And yeah, I'm just complaining. I'm sure my drill will be okay, and do know how to resharpen bits.

I just bought the plans. Can anyone tell me the advantage of the holes in the verticals (A) being off center?
Also, I see other benders with aluminum dies. Anyone use aluminum dies in this bender? I could make cast aluminum dies.
Thanks!

Having built one, I can't imagine going through all the work that it took to build one of these, and then (for lack of drilling a few more holes) not being able to use a standard protools die set of a different size and radius, that you may buy/encounter in the future.

The arms and uprights are hardly "easy to redrill later". Would be an absolute bitch to do, compared to just drilling before everything is welded up.

Building one of these as a "one trick pony" would be plain crazy, but hey, it's your project.

There is no "advantage", its simply the way that the geometry works out, based on the location of the arm pivot.

Ditto on that. It would probably be easier to just cut the bitch back apart, drill the remaining holes on a drill press and then weld the SOB back together.

It's kinda like the sign that my old bossman had hanging on his office wall. It said, "If you ain't got time to do it right the first time, how are you going to have time to do it over?"
