JD2 Model3, Pro-tools 105, and JMR Benders Compared
JD2 Model3, Pro-tools 105, and JMR Benders Compared
Published by KeithXtreme

Arrow Dies



The dies we will use in the second part of this comparison will all be 1.75 tubing dies.

I will go ahead of show some photos and specs of these dies. The photos show exactly what is delivered to you when you purchase a die from any of the three companies.

You will notice that JD2 does not provide any other pins, your drive pin, and strap pin are included with the purchase of the bender.

Pro-tools provides a new strap pin, backing block pin, and a tension tab pin if your requested a tab be installed on your die with the purchase of every die.

JMR provides an additional strap pin with the purchase of every die.

Here is a photo of the Tube straps for each company just to show you the different approaches each company has to their dies. All the straps are .250" thick

JD2 1.75 Die;

1-3/4" OD Tubing, .095" minimum wall thickness and a 5.5" CLR. I could not find what the maximum wall thickness was for this die. JD2 dies are 210 degrees which enable you to bend 180 degrees. The tension tab on the back of the die is 1.5" wide and 1.250" thick and uses a .75" tension bolt. This is also where the bolt is to wrap your tig rod pointer around is.

JD2 dies are solid steel billets and carry a lifetime guarantee against breakage. The material in their replaceable inserts in their backing blocks seems to be a secret.

Pro-tools 1.75 x 6 x 240

Pro-tools dies are available in either a 120 or 240 version. the 120 dies enable you to bend 110 degrees, while the 240 versions enable you to bend 180 degrees.

Pro-tools uses Steel Billet for their Main Dies and Backing Blocks, Steel Pin, Steel Strap and provide a Lifetime Warranty against Breakage. the main die is also covered in their two part epoxy.

The strap tab is 1.50" wide and 1" thick and uses a .375 tension bolt.

JMR dies are available in either a 120 or 240 version. JMR uses Cold Rolled Alloy Bar Stock for their Main Dies and follower blocks are case hardened. You can see this in the finish on the backing blocks. Lifetime guarantee against breakage on dies

The strap tab is 2" Wide and 1" Thick and uses a .375" tension bolt.

Keith, good job with this review so far, I'm looking forward to the rest.

At some point in this review could you demonstrate the proper use of the adjustable stop on the PT105STD? I haven't taken much time to figure mine out, but then again I haven't asked anyone either. I'm pretty sure I know how it works, but I haven't used it yet. I just thought it might be nice to show so everyone can see. Thanks for taking the time to do this review.

all 3 side by side

First time I have heard of someone getting a chance to break down the nuts and bolts of each bender and seeing what they look like side by side.

Thanks for the review.

That's a nice set of photos outlining the few differences among the benders. One thing that's been rumored is that the JMR and Pro Tools dies are interchangeable. Is this true?

Yes

Quoted from the reveiw:
Backing block pin holes on the Pro-tools 105 and JMR Benders are .125” apart and .375” apart on the Model3, combine this with different drive pin locations on the dies and this means that dies are not interchangeable between JD and either Pro-Tools or JMR. But the dies from Pro-tools and JMR are interchangeable.

Keith the write up is very informative. I do have one question. Every die I have purchaced (all 240 for Pro-Tools) have had the tension block already welded to it. When I purchaced new follow dies They sent me ones with no block welded so I enquired. They Pro-Tools told me that on the 240 deg you get the block pre-welded, but it was not used on the 120 deg units although they are the same follow die, and if I had speified which die I had the new ones would have come with them. 2 days later the parts showed up for me to weld on. Great customer service..

That is news to me, Jim my sales person there had always told me they do not put them on unless 4130 was specified as a material you would be bending.

But over the years, Jim had just grown accustomed to adding it to all my die orders. So that is good info to have and just goes to show you the great customer service they have. I could not have the kind of customer service I have unless they backed me the way that they do.

I also try to keep a few of those tabs in stock for just such occasions.....

I just got off the phone with Jim, the owner of JMR and there are a few corrections to some of the statements in the comparison. I have changed them in the comparison, but I also wanted to post them here for a quick reference.

I originally said the dies from JMR where Steel Billet, they are in fact made from Cold Rolled Alloy Bar Stock and CNC Machined.

The finish of the JMR bender was quoted as being Hard Anodized, they are in fact Black Zinc Hard Coated.

I had a few questions today on those issues and JMR cleared them up for me.

Excellent writeup! Definately makes it easier for first-time buyers.

The only question I have relates to the listed capacities...they're stated as max OD, but not material or wall thickness. It appears from just the listed specs that the JMR can handle a 2.5" OD round tube, but is that HREW, DOM, 4130, and in what wall thickness?

Thanks very much,
Sean

**Found it with some web wheeling...JMR states 0.25 wall 4130, I'm having trouble finding a max capacity for the 105HD...anyone know offhand? Thanks!

I could not get any specs on the JD stuff for tubing, they always say call.....Pro-tools is .134 4130 and The JMR is .250 wall 4130 because it has the heat treated backing block......

So if I get this right (new at this stuff!), the difference in capacity is the die set, not the arms or pins, correct? So the 105HD could do a 2.0 OD .134 4130 if it were running hydro, or I had a herd of gorillas handy?

Thanks,
Sean

Its a combination of both....you need nice thick arms to do 2" and the benders have to be made with enough clearance to fit a two inch die....

But yes you could do 2" on the 105hd .134 4130 with the breaker par they sell...it is not easy but you can do it....

The Pro-tools and JMR are very easy to bend manually with, because the swing arms are longer than the JD arms. As far as bend quality, they are all about the same, which is inherent on proper setup and the use lube....

What I wanted to test was the claims of .250 wall bending and just have not got to it.....As soon as I can get to it I will, thanks for your patience....Keith

Whoa I just found out that I bought the (according to this article) best bender on the market. Wheww, I'm glad I did one thing right when I was just stareting out. Now I finally know that the grand I dropped on the bender and all the differant dies was woth it.

Which one did you buy? for the record.....

I bought the m-tech bender, but I think its a knock off of the others. No special tooling on the pins, no laser on the degree wheel just a plain old bender that works everytime I use it.
