Thank you sir! My bender is a JD Squared Model 3. I have the 1 inch and 1.250 dies for it. It works good as it with no hydraulic power for doing small jobs. I use a 4 foot piece of rectangular tubing for a handle. I am in the process of making a plane of angle mounting clamp for the tube so I can attach an angle finder. I need that to do the bends for the lower tubes as they require rotating the tube a certain number of degrees before making the subsequent bend. I can buy on for $50, but on can be cut from 1/2" steel. I just need to get that done. I'll post a picture as soon as I do.

I got another part of the neck fixture done. See pic.

Welcome aboard!
I got this wheel; an 5.5x18, 80 spoke and AL hub. It was cheap, probably chinese components I guess? I think it's a DNA.

I found this idea out on the web: fab a plane of bend clamp out of angle iron. The large it 2 1/2" and smaller angle is 1". It's not pretty but it will work...better than paying 50 bones for one on ebay. I'm a po mofo! The money is better spent on chopper parts.

I do need to buy a new angle finder though as this one is crap and I've already glued the needle back on...!

Here is their website with pricing for the bender, dies and other stuff. I bought this one about 10 years ago. The model 3 is now $295 and the dies vary depending on size. http://www.jd2.com/

OK a little update. Unfortunately at this stage it doesn't look like much...I angled the neck fixture of the jig forward 20* and then adjusted the steering tube to 45* rake for this 43.5" long springer fork I want to use. I mocked it up with some yardsticks to check the height. I have the top frame tube stretched out another 3" from the plans that I am using, which are already 4" out from a '48 rigid pan frame. Looks like it should fit and look good at this angle...comments?

Looking at the third picture down, you can see that the wheel center is only 9.5 inches off the ground, the small silver sharpie line represents the ground, so that effectively raises my lower frame tubes up.
I know this means my lower rails will be about 4" higher than at the planned height of 5", but when all of the weight is put in, it should come down to it's planned ride height of around 4.5 - 5 inches. Maybe..I hope...
Also mocked up the handlebar riser height and looks like I will need a 12 - 14 inch tall bars to be able to reach them...The springer risers are 6" up from the top of the neck...

Today I printed a template for the miter on the top tube where it meets the head tube and set it back in the jig. The head angle came in at about 42 degrees after I got it all set and I think that will be good. It looks a bit better to my eye than all way out at 45, so i think I'll stick with this for now. I had to do a little filing on the jig and tweaking on the frame top tube to get it aligned perfectly with the head tube when installed in the jig. You need to that with steel after you weld it up as it moves around some.

"Quality . . . you know what it is, yet you don't know what it is. But that's self-contradictory. But some things are better than others, that is, they have more quality. But when you try to say what the quality is, apart from the things that have it, it all goes poof! There's nothing to talk about. But if you can't say what Quality is, how do you know what it is, or how do you know that it even exists? If no one knows what it is, then for all practical purposes it doesn't exist at all. But for all practical purposes it really does exist."
