Thread: What did you weld today?

I gave up on buying collectors and started to build my own. It's nice to have a steeper angle or not so steep sometimes depending on the application. It's a nightmare to figure the first one out but after that you can knock them out pretty quick.

I'm a DIY guy who doesn't like to spend a dime more than I have to. I build all my manifolds out of sch 40 mild steel. I make collectors myself. First one I made was with an angle grinder and cutoff wheel. After that I made a jig to cut the slices on a cutoff chop saw. I agree with the above, making your own is better as you can make them longer or shorter as needed. I design the manifold in the computer to determine how many bends I'll need and I only order the quantity needed. I fit the pieces using an angle grinder and bench top belt sander. It's down and dirty, but does the job.

for the time it takes to make a collector one could be bought for a lot less.

as far as mild steel why would u bother making manifold out of mild. only way to do it it ss.

wats the difference between both? ive was always told that stainless is harder to bend, does the same goes for mild steel also I was looking at the extreme builders kit, do you think its enough pipe to make a simple manifold, I am not trying to make anything crazy.? something similar to a sidewinder, maybe not as long or simple down and over one

You need some good piping to make a turbo manifold. They get put under some pretty extreme stresses.

deff need some solid piping.

thick wall sch 10 ss

for most manifolds.

That's why I go with sch 40 mild. I'm not building manifolds for sale, I'm building them for my personal DIY builds. Why spend the extra money if I'm not making a profit anyways?

As for bending, I don't know about you guys, but I don't bend at all. I buy sch 40 90*s and 45*s, then cut and fit as needed.

Stainless does so much better under stress IMO

Whats mine made of matt?

So far its doing great

I'm not trying to get into which is better and which is worse. I said I use mild steel because it's cheaper. I don't make money off my manifolds, so the cheaper the better.

Stainless does better under stress due to it's ability to flex. I haven't had a mild manifold crack on me yet, but if it does I'll just bevel and weld it up.

Back to welding, my GA16DET setup has been done for a few weeks now.
