I do wonder about my bender and dies being up to doing a nice job on .058" 4130. I have to pull out my bender and check, but I believe the 1.5" die I have is for 5.5" centerline radius bends. I don't know if it is too tight (no inside mandrel) to bend without kinks or ripples. I guess the only way I'll know is to get some tube and try it out.
The bender I have is a JD2, and if I recall from conversation with dreracecar on another website (the HAMB) that it isn't exactly the preferred bender to use anyway. I guess I'll just have to get some 4130 of a couple sizes and do some test bends to answer that uncertainty for myself. I do recall from previous use that my 1 3/4", 6.5" centerline radius die created an unacceptable, rippled inside radius on 16 Ga. HREW tube. I don't recall ever bending anything under .083" with the 1.5" die, but I fear the tighter radius on it will have the same problem when bending 4130.
I know I keep saying it, but I do appreciate the suggestions and advice from everyone.

Your JD2 will be just fine with the right die set.

I have another suggestion ! Why not look into a chassis kit ! It would come with all of the major bends you need and you build it the way you want it ! As far as the rear end an 8 3/4 mopar rear would be just fine for what you are doing and they still make a lot of good parts for them ! Stay away from an open rear and use a spool ! Use a nice small tire ! For something like you are running a 9 inch tire would be good ! Just do it and don't let your age get in the way ! I just tuned 69 this year and have no plans on stopping !

I have a Pro Tools bender which is just a clone of the JD2 and it sometimes has problems with 1.5" x .058" with a 6" CLR die. I either use .065" and splice it to the .058" with the sleeve in the front cage hoop area or I go to Force's shop and bend it on their $100K mandrel bender (which obviously is not an option for you ;D)

I made a call yesterday to a friend of mine who builds dirt circle track modifieds and has a Mittler Bros. bender. It's the type that has a shoe to support the tube on the outer radius of the bend as it's drawn around the die. So, I believe I have tube bending covered.
Now, if my projects would just sell! I have a "barn find" '48 Ford coupe that I've lost interest in. The other is a fiberglass '33 Willys. The Willys is a "stretch" version by Dennis Taylor. I bought it as a body and bare chassis. It now has a Moser 9" and triangulated 4-link and Mustang II front suspension under it, so it's in bare "roller" state. It's a blank canvas now and could either go the direction of street rod or drag race. My phone number and e-mail are below if someone is interested. I do have photos that I could send via text or e-mail. Location is Southeast Missouri.

You will not get any good bends with 16ga mils steel tubing without a mandrel to support the ID at the start of the bend. To start any bend, the tubing has to crush first and mild that thin never recovers. Lots of people use the JD bender, , I prefer the Hossfeld as It produces a better bend for me.
