Nice work Jerry! Just plz make sure that the small end is close in size to the T3 inlet size and not alot bigger. But looks really good!

Can you post up the jig you used to cut that? How many degrees are those cuts? I'm trying to make one for my cut off saw right now, and it's pissing me off. I want it where I can still do 90deg cuts on the saw without having to change all kinds of shit.
the cuts have to be between 11-15 degrees,11deg cuts are pain to weld but they can be done.
my jig wont help you with a cutoff saw,its spifically made for a bandsaw.
I can guide you through making one for your cut off saw though.
it took me 2 day's to figure out how to make the jig so i feel you'r pain.
once you set it up and cut one,you have to cut all 4 there is no going back. make sure you have a square,to check all you'r cut's.
also get some plastic 1.5" pipe to pratice on. It's cheaper than steel.
when you make the cuts dont force the saw,let it cut slowly.
this is a genaric drawing. I hope this helps....
I was just giving you shit about the apostrophe thing..
As far as my jig, it'll be just a plate with a drill press vise on it. The whole thing will sit on top of the cut off saw in place of its (hey, where's the apostrophe..lol..is that a possessive or contraction or both..? wtf..) original clamping mechanism. The plate will just swivel on the axis of the original clamp, (horizontal) except the new clamp will be a lot farther out on the axis of the swivel point, allowing it to get a lot closer to parallel with the saw blade before it gets in the way of the blade. It's actually really simple, I'd already have it done, but the local guy who I'd buy the metal from was closed today.
After I do that, I'll build a twin scroll collector and post it up on here. I need to get a turbo so I can build the rest of the manifold, but for now I'll just do the collector. I can do some nice shit with my tig welder. It makes my old mig welds look like they were done by a stoned monkey.
are we going to have to change your name to "English teacher" or "stoned monkey" lol....
anyway i see where you are going with vice and i like it. My question is are you going to be able to replicate 8 cuts, and make them as exact as the first. straight cuts are not as critical as angle cuts. That being said if you are off by a 1/16 of an inch in any of the cuts it will throw off the entire collector and cause you to spend hours grinding or re-cutting. I am sure you are aware of the power of the saw. so let's say your pipe length is 5" (you can cut them longer but you will have more waste) and in order to cut the pipe without cutting into the vice you'll only get about 1" to 1.5" of bite on the pipe. Is that going to be enough to hold the pipe perfectly level and keep it in place? The vice it self would have to be mounted in a way that there would be absolutely no movement.
i know you have spent alot of time thinking about this so I am just trying to point out some of the things i can think of that can make a difference in the final product. I tend to over think things sometimes, but without questions there are no answers.Think of this as R&D.
there is only like 3 maybe 4 of us willing or have the ability to take on building a manifold from scratch so if we can help each other out all the better.
I wonder if you really could train a monkey to weld. That'd be pretty tight. I mean, there are birds that have the vocabulary and comprehension of 4 year olds, so..
I wish I had a camera and the metal piece so I could just stfu, build it, test it, and post it up. I know what you're saying about keeping the pipe in the same location relative to the blade, I looked at your illustration and I think it's a good idea how you have the pipe bottom out against the flat stock to keep the cuts lined up. It would be nice to have that be adjustable. I'll probably incorporate something similiar into my design.
Another thing about the collector is once it's made, you're going to have to cut it off at the end so it fits flat on the flange. I might have a couple ideas, but I haven't figured out a good way to hold it for that yet. How did you plan on doing that?
Another thing that I've discovered, annoyingly enough, is that for the tubes to fit a rectangular flange, like a t3, each tube has to have 2 different angle cuts, so the collector comes out rectangular. Now my jig is fucked, because I just welded the clamp onto the plate at the angle I wanted. Maybe I can just hammer/press the collector into that stupid rectangle, if I want to make a t3 single scroll setup. I was planning on making a twin scroll manifold, so it won't matter for that.
So how did you get the collector to end up rectangular? Did you do the 2 different angle cuts on each tube, or just hammer it into shape?
Can you post a pic of the inside of the collector?
in order to get the rectangular shape you have the option of :
cutting the pipe with 2 different lenths but you use the same angle.
cut them all the same weld(or tack) them into 2 halves then recut or trim 1/8" to 1/4" off each.
or you can use a tabletop belt/disk sander.

damn that's all i get for all my blood sweat and beers....lol
2 pat's on the back and see ya!
you guy's know this thread isn't just for me, accordepicenter and accordtheory to post in right! right!
thanks bitesize and labeledskater you guy's rock! (as "Iron man" plays in the background)
i am a little old to be rocking out like that but what hell i was a stoner back in the day and that was my era!
damn!my neck hurts!
(as i collect myself)back on topic.
that came out really nice jerry. I still have a load of work to do on mine. I bet yours will still look better than mine even when im finished. Grinding welds down is too baller for me

When you get it all ready to go, you should post up pics of the inside of the turbine housing and collector, so we can see how you made them match. I finally bought a turbo, hopefully it'll arrive soon so I can start figuring this shit out again too.
