drawings for tubing benders...

[dsergison]

Morpheus, if it wouldn't be too much trouble I would still like the jd2 bender dimensions.

the protools calls for a 5 1/2" wide outer arms, and I have 3" x 3/4"material.

My die is starting to really shape up too!

is there a place on the hobart board to host pics so I can share them with ya?

I did not do the drawings I posted, so I have no idea what software they were originally done in. I did build a model in Inventor that i used to practice using the software some. I'm learning it in my spare time.

[dsergison]

ah. a pro/e drawing.

don't happen to have a model?

I'm a pro-e guy too. In fact that's my day job. well it was until about a month ago. now I'm a photoshop guy for a little while.

I do what i can like I said, no guarnatees on the dims. I built a computer model of it based on those dims. only issue i found was possible interfence where the one bar is notched out to go around the pins. Might need a just a tad more notching then what is shown.

[dsergison]

you da man!

sure do appreciate it.



I got my first die roughed out this weekend. I'll try to post a pic of the process soon.

I got these from a fellow on Pirate4x4. No guarantees on the accuracy. He said he's made one or 2 with these dimensions though. These are for Protools dies I believe.

I have not gotten a chance to make one of my own.

I can get you dimensions from my JD2 (www.jd2.com) bender ...

I can believe the cost of the dies now!

well I set out to make my first die last night. :P

I acquired a 1 1/2" thick slab of steel, roughly lunch tray size but with a corner cut out. It was drop from some huge unknown Cat equipment fabrication operation.

so I drill a 3/4" hole in it at the pivot point. That went surprisingly well, and I put it then on my 10" rotary table and I figured I'd swing it under a 1/2" endmill and rough out a 210 degree 5" radius arc.

(I had planned that after I roughed it out, I'd tur the table vertical and start spinning it inder a fly cutter.)


Well, I got through about a 1/4" of the plate and I've decided that I'll have expended nearly $200 in electricity, and many more time that amount in sweat before it's done.


On the other hand, my progress on making the bender it's self is almost encouraging. I'm planning on using 3/4" pins through my 5/8" arms. I drilled the pivot holea, I just need to lay out the pin holes. I could use a few dimensions for that if anyone is willing to share.

At least with standard dimensions I could buy dies to fit, and just make the frame and guive up on the dies.

I was reading up on the Hossfeld bender and man do they have a TON of different odd ball dies for that thing...square tube dies set at a diagonal, dies for angle iron bending, etc. Too bad all their stuff is rediculously priced as well. That would be cool to have a do-all bender...but you would have $2000 in it with a few sets of dies and angle benders! I'd rather spend it on a TIG welder.

yep, a Hossfeld is The Bender of All Benders. It can do it all if you have the right pieces. All that ability comes at a price though.

I personally like the style of the JD2 a little better too. What we need to do is form a "share the die" program and just swap out the odd dies we need from time to time.

I've seen that bender on eBay. $680 + $50 shipping ... they've come down alot. Back before I bought my JD2, they were selling for about $850 + shipping ... I've heard of problems with other benders with aluminum dies so beware ...

There is a guy on ebay making/selling a bender, much like the Protools, comes with 4 sets of dies (1" - 1 1/2") 90 degree, for $680...for everything. Do a search for "tubing bender". Not too bad a price if you need all those dies. My plan is to use the compact HF bender and some of the cheap dies for 3/4-1" stuff and get the JD2 with a 1 1/2 round tube die for the bigger stuff.

Those dies are a bite in the rear, I can't believe they cost that much....well, yes I can. But still.

Good luck making some, that would be great if it works out!
