I found this picture on a VW board..

How do you cut and bend tubing like that?

 

you might want to do a search first. there is alot of posts about it

 

I'm wondering, if the difference would be noticeable when comparing tube-style collectors with box-like collectors like the one below:




besides it being ugly, for do-it-yourselfers.. it's really easy.

Tried that buddy, just help me out if you can find it .


I dont think transition like that are ideal when making a manifold.

 

Defintley a large difference if the header behind it is designed correctly

not sure if im understanding your cuqestion right but to do have a bend in the collector you usually fabricate with pre bent tubing

 

Yeah basically I would like to know how to make one.

I've asked one manifold builder and he got all butt raped about ppl stealing designs from him...

I thought I was asking a general question? Oh well nevermind him.

So basically in this picture the tubing was actually a bend basically with a bunch half cuts?

 

yep

In that pic I'm not see this bend you guy's are talking about, that collector is cut from straight sch.40 pipe.

Yah, there is at LEAST one post i remember with someone doing a walkthrough on DIY collectors. He made a simple jig to cut the straight pieces 2x at the desired location/angle. do that 8x (2x per piece) and then fit up and weld. If the measurements/cuts were accurate, it'll line up nicely.

 

Good luck finding any answers. People like to keep these things secret.

 

Just make some kind of jig all you have to do is take 4 equal length pieces of pipe and cut them on 2 sides 90 degrees apart from each other at the same angle

everybody is still making a big deal outa this? I will have to look around for that DIY

 

buy some pvc pipe 1.5 inch sched 40 and expermint with jigs and when you figure it out cut steel its not that hard

 

 

I would've thought casey would know ? Looks sure to me :-\ .

 

ya there are several posts about it. I even MS painted a pic of my collecter jig for a band saw.

A box style collector versus a merge

?? im confused we dont use a fixture to cut our tubes

 

There are no bends, its just two cuts on a straight piece of pipe. The angle and spacing I do not know.

 

mmmm what exactly to you use to make those fancy pants collectors ?

Pretty sure Casey is not going to take pictures of the jigs they use, or how they do things.

 

Hands a band saw and lots of time....... can't say much more
