Wheres the tube bending 101 part 2?

Im looking for info that will help with the compound bends.All that math hurts my brain Is there an easy way to calculate and figure out what degree a compound bend is?And yes Ive searched ,and heard sombody was going to do a better write up on the compound bends.

I just look at it...rotate the tube where i want the new bend to point at, then mark my tube at the top for the bending plane....

I'm not sure I understand the question. Do you mean your say bending a main hoop with a trapazoid shape? Like a 75* followed by a 15* for an total angle of 90*, (one half of the hoop)? Or are you talking different directional planes, X, Y and Z axis'?

As far as I can see, the "Tube Bending 101" method cannot really be applied directly to bends in multiple planes, and it is not intended to do so either... You can always eyeball it, or step up and learn the calculations involved - which puts you into the Bending 300 and 400 series graduate level classes

i think he understands that 101 is for bending single plane parts. He is wondering how to do the multi-plane stuff..hoping someone will do a 102 and make x.y.z bends

I think Tin Bender mentioned he wasn;t going to do a 102 because there was already some guys in the industry that were upset he did 101...something along those lines. 101 is intended to get you started, everything else is up to you

Well, the more people that know how to bend tube, the less people there are for the shops to build cages, sliders, etc for...its already hard enough for most shops to stay alive as it is...

If he is ready for multi plane bends - perhaps it is time he take the extra steps and learn the math involved in calculating bends...

Bend-Tech will definitely handle this with ease. Place in your XYZ locations for each bend and it will automatically calculate the cut length, bend location and rotation amount. I am currently running special prices for Bend-Tech EZ and Bend-Tech. If anyone would like a quote please email me at sales@2020softwaresolutions.com

Thanks

Thanks for all the replies .I was talking about bending on a different plane xyz.After wasting allot of expensive tube I was hoping there was a easy way like the 101 method.I havent been bending for very long and Im not sure I can afford to try compounds yet.Im going to look into that computer program though thanks!!

For me (Keep It Simple Stupid) Works the best. I made a little clamp on jig with a level and angle finder. I can mark a refrence point find my angles, then reproduce them on the bender (usualy). I havent tried the sorftware, tempted, but to me its more like an art, I can do the calcs but most of te time I use scraps and jigs for mark up.

I think learning your dies is one of the mre important things figuring your realsitic CLR start of bends, spring back, How close and what kinda compunds can I fit in the bender kinda stuff.

I can understand why this may seem like art; however, it is a science and can easily be defined by software. This will reduce if not eliminate scrap and allow you to take the time trying to figure out bending tube towards other things like suspension, engine, beer drinking, etc.

I am working on an expansion program to Bend-Tech EZ that will blow your socks off for 3D parts. I hope to have to market in about 4 weeks. The price should fall into a range that should pay for it in less than 1 stick of DOM.

When it becomes available I am going to announce it on Offroad Fabrication Network. Email me if you would like to be put on a list for information at time of release. Anyone who has Bend-Tech EZ will receive an automatic rebate for the new product.

I use a long piece of .25 steel rod. Just bend it to the shape you need. Then take it with you to the bender.

Bend-Tech EZ-3D has been created because of demand from the 4x4 fabricator. Many of you have asked for a product to help with rotational calculations without the difficulty of using a complex system. We spent several months creating a product that everyone can understand and use and still give you the information you need in a short time. We have taken Bend-Tech EZ and added an extremely easy to use 3D interface.

EZ-3D is EZ with a serious twist.

Here is a list of the major additions to create EZ-3D:
1) 3D Custom part interface (revolutionary Tri-Star input window. Uses understandable terms; to front, to back, to left, to right, to floor and to ceiling. You put in the locations and we will give you the angles and rotations.)
2) Rotation output (EZ-3D calculates your rotations!!!)
3) Flip a part during mid production (EZ-3D automatically calculates the new locations, bend order and rotations.
4) Simulation (Watch your part manufactured prior to touching your machine)
5) Transitional Setup Sheet (a second setup sheet showing a graphical step process of every "push", "rotation", "bend" and "flip")
6) 60 Page Manual (60 page manual goes through installation, operations, tutorials and trouble shooting)


If you are tired of calculating rotations and creating scrap; EZ-3D is the answer.

Price: $149.00
Upgrade price for EZ customers: only $90.00

Phone Number: 651-257-8715


The interface for Bend-Tech EZ-3D


Tri-Star; uses terms like: to front, to back, to left and to right


Output rotation, flip the part in the middle of the bending process


Snap shot of the simulation process bending the part


1 slide of the new secondary setup sheet.

I agree, isn't that what most of us are here for..to get tips and learn how to do things ourselves? And who are these "industry" guys to tell the Tin Benders
anything. The Pirate board obviously thought is was worthy to give them the space to have the writeup.
I guess we better not post anything on how to fix our own engines, modify our suspensions, etc. or god forbid we might put all the shops out of business.

Rant over...have a nice day!

Those that are insecure in there abilitys should be leary of giving away secret's its the only livley hood they have. I have lost track of the amount of tube we have bent for customers and the amount of people we have helped bend tube.. As long as there is a need to fabricate something different or unique I will always make money. For those that are interested in learning my suggestion is 1) find a good shop and hang around ask questions and learn or take the plunge and by the bender you want and like fabcam has shown there is software out here that realy does work. I have used all 3 products ez ez 3d and 2.0 all of them work and work efficiantley with no waisted tube.
It is an investment, but if you can read a tape measure, no your true CLR anyone with 3/4 of a brain can pull the handle on a bender...

A little bit of high school trig, some graph paper, a scientific calculator and a centering head and it is not real difficult.
