Advice on what radius for new die set? - Pirate4x4.Com : 4x4 and Off-Road Forum

DRM · 06-23-2004, 07:06 PM

Looking to get a second die set for my JD2 bender, 1" tube die this time. I see a variety of radius options for the 180* dies...

To make this a bit more universally applicable - what should be the criteria or determining factor to choosing the raidus of die sets for purchase and use?

Thanks

I would think it might be a benefet to get dies with the same radius in case you want to piggy back a tube over another

like a 1" tube piggy backed on a chassie tube to help protect the chassie tube

Mark Berger has tube like this to help protect the body panels on his buggy

just a thought

general rule of thumb,

for the kind of tubing work done on race cars you will find that the smallest radius available will be of the most use. unless you have a specific need for a larger radius i would buy the smallest radius availabe for the diameter tube you are getting.

basically a smaller radius bend will always fit in a larger area but a larger radius bend will not fit in a smaller area

Camo - that was the line of thinking I came to on my own, but was looking for input from others if there was something I was missing.

I know the only other issue with too tight of a radius is the wall limitations - basically forcing you to use heavier tube than you might want for a project because the lighter wall would kink on the tight bend...

bignissan · 06-23-2004, 09:14 PM

the wall thickness is still pretty thin for the min wall though. How thin do you want to go?

BadDog · 06-24-2004, 08:49 AM

I agree, get the minimum radius possible for the thinnest tube wall you expect to bend. That's what I've done with all my dies and I've not had cause to second guess that decision...

66CJdean · 06-24-2004, 09:21 AM

Most of the dies will state what wall they will bend. I went with the thinnest wall I would want to bend so for me it was the larger radious of the 2 they offered. I really don't care how tight of a radious it will bend for the most part.

I just bought a 2" last week and went with the bigger radius 7" over the 6" as the 7" is spec'd to do .095 wall which is somthing i may likly use.

That said i do have small radius on the smaller tubes. 4.5" on my 1" and i forget what the 1.5" is...

-mike
And my official responce still is... NO i do NOT have a tubing bender.

DRM · 06-24-2004, 11:34 AM

Well, the 1" dies I saw were 3" or 3.5" radius, and they may have had larger...

THURENfab. · 06-24-2004, 12:11 PM

I'd go small on the radius also.... With smaller tubes it seem that it would be nice to get into tight spots and having less "bent" area for welding tabs to and whatnot......

I'm nabbing a 3" radius, 1" round die next week. I wish I would have gone smallest radius possible on the other three dies I have.

Rudezuk · 06-25-2004, 02:00 PM

I have the 3.5" radius and works awesome for what we need.....And it allows you to go with a little thinner walled tubing too

heavytlc · 06-26-2004, 09:27 AM

I have all dies from 3/4-2inch with my tube shark, I bought the smallest radius sold in most cases. I have 4 and 6inch in 1.5, and 5and 7inch in1.75. I always use the 4 and the 5, they make much sexier bends IMO, and you know sex sells

For what most of us build the smaller radius works better, but I do not want to start an argument over the strength of the larger radius. You were asking about 1inch, I will assume that strength is not a top priority, you will be using this for gussets, grab handles, racks and such.

SHERPA · 06-27-2004, 02:01 PM

I have a 3" RADII die in 1" tube that works killer for .120 tube, but when I try
to do fairly thinwall DOM tube with it, it can kink easily........ sometimes it does, sometimes not.......... bummer to ruin a peice by kinking though....

Specifically - I would be getting it to make a roof-rack for a co-worker's Rover, and would end later using it for glab handles, gussets, light guards, and other small non-structural pieces...

What radius would you guys use for making a rear seat cradle to add to a rollcage? I am probably going to make it out of 1" tubing.

Reflexx · 01-20-2007, 08:02 PM

I have:

1.00 x 3.0
1.25 x 4.5
1.50 x 6.0

Why? I dunno, but it works great for 99.99% of waht I'm doing.
