Rorty Bender Build Thread

Post by N*A*M »

I have most of the bender pieces. Still waiting for dies to be machined (cost $560). I won't get much change out of $1000 by the time I finish but that's okay.

Not much tech for now. Just pics of some of the parts.

Firstly, the plates that form the main arms.

Secondly, the spigot for breaker bar.

NAM,
What material are you using for the dies?

Are they being done on CNC equip?

Are you making the bigger rorty 2?

The plans say the bender can't be used for pipe, did the vendor give you any idea of the wall thickness tube this gear can handle? I emailed him but no reply.... :roll:


Cheers
Daryl

daryl

the dies will be made from D2 tool steel

http://www.timken.com/products/specialt ... lympic.htm

yes, CNC'd

correct, rorty model 2 bender. it is very beefy!

pipe is not dimensionally accurate hence the reason this would not work well with it. this should have no issues bending 0.120 wall tube.

strange you mention that cos bob was pretty prompt with his replies to me. maybe he's on holidays?

NAM,
Is that all the dies for $560?
If possible could you get a price for a complete second set. If its cheaper now thats he's programmed I might be interested in splitting the difference with you if you could do the footwork/freight thing.

Cheers

unfortunately that is $560 for a set of 1.5" structural tube dies

it can get very expensive as you can see

you would save about $150 by going mild steel instead of d2

if i were you, i would "borrow" a jd2 bender and have a shop make you one just like it so that you can also use jd2 dies

pm if you still wanna get a copy, but maybe wait till i finish first - in case it doesn't work!

why do you have to go D2 instead of mild steel?

from link above:

D2 tool steel is a versatile high-carbon, high-chromium, air-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium-rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials. Although other steels with improved toughness or improved wear resistance are available, D2 provides an effective combination of wear resistance and toughness, tool performance, price, and a wide variety of product forms.

i didn't want to spend $$$ having the dies machined only to have them open up with use. since it's a big money project, i might as well do it right.
