oh man, i think i need a lathe

 

I bought one. It's pretty sweet, although the angle marks are only accurate for 1.5" pipe. I figured this out after some unsuccessful attempts at making a collector with 1.25" pipe and talking to Justin on FB about it. It should still be very useful in the long run.

 

Cutting anything on a chop saw sucks..... the clean up is horrible. I practiced once on some PCV and it came out great at 90degrees. Once i went to cut with the SS the blade deflection made it a difficult task. I plan to get a band saw one of these days and give it another shot.

 

Seeing that fixture Justin created makes me wonder if it would be possible to use one of these: Wilton Drill Press Vise, Angle, Cradle Style, 3 in 11753 | Zoro.com to accomplish the same thing.

It made me wonder so much that I bought one and am going to give it a whirl. Can be locked at any angle between 0 and 90 so I think with some minor modifications it has potential. With the coupon I had it was just north of $50 delivered so hell, why not. Lol. Even if it fails miserably for collectors I don't doubt I'll find another use for it.

 

That's a nice piece. Let us know how it works out for you. I'd buy one

 

something we slapped together with some scrap bits laying together. works very well. the belt sander is your friend when doing something like this to get the fitment perfect before welding though

 

What angle do you guys use?

 

I used 22.5 degrees on the twinscroll collector I just made yesterday. Since it's my first manifold, I wanted to make sure I would be able to weld it up.

 

Not bad for your first one...

 

Little update on my indexable drill press vise that seems to be just the ticket for doing collectors.

It showed up yesterday and I was able to play around with it a little bit today. We were pretty slow because it snowed most of the day.

Came to the conclusion that the vise will work as I originally thought, and I'm going to be able to make it really sweet with an angle gauge, step block, and v-jaws.

Unfortunately my cold saw doesn't quite have the vertical clearance for the setup to work as well as I'd like so I bought a second one that I'm going to modify. I'm planning to make a riser, possibly a modular riser system if I have time, but bare minimum one riser to move the saw head up off the table 3-4 inches to give me plenty of room to work.

I will update later and post some pictures when it's appropriately re-engineered and setup. Needless to say, I'm pretty excited. According to ups the saw is going to be here wednesday.

 

Depends on the situation. There's not really a one size fits all.

 

How would one make one of these collectors? I've always used normal straight ones, cut about 4 to 5 inches and used 18 Deg angles. This time my space is very restricted. I'm struggling to build a jig to cut these, can anyone help? Here's a couple of pictures of what I want to do:

 

There Are some good ideas here, I think I better get my jig built now.

 

This is not something you'd use a jig for. I'd do this with a 4.5" grinder and some time on the belt sander to make sure it's all fine tuned. Definitely not something you'd want to build en mass.

Thanks

Just to confirm something if I have it right in my head, that 0 degree reference, is that what they mean by the reference from a zero plane? Eg, if I marked a piece of pipe / tube and used that mark against that 0 degree marking - is that what I reference every cut from? Referencing and rotating from both those points?
Thanks

 

this is my first collector. turbo and flange is borg warner s200sx (little t4 size)
made on little bandsaw with 59° angle.



im waiting for my 2x precision wastegates to weld the 44mm flange on

welding is not my job. ive learned it from a friend. just learning by doing.
