Surprised with how thick you went for the material. Good welds. Permanent marker is not a good reference for S.S. on temperature range. You don't want to reach, or go beyond 316C, as that's where carbon precipitate will start to become a problem. If you have a temp gun, using that to check around the Heat Affected Zone will let you know if you're putting in too much heat. Your chill block idea is great, and you did a great job spread the heat around with little weld sections at a time. The only thing I saw that would have me concerned about, is when you used your air hammer to shape the end. If that punch was carbon steel, that can imbed carbon into the S.S and cause corrosion in time. Regardless, thank you for a great video. Especially the still motion!!! That was great. A great job!

Cross contamination from carbon steel is from soft steel. 0.401 shank air chisels are tool steel at minimum so risk is minimal. Remember, wrought weld butt fittings and pipe are formed in tool steel dies. And bandsaw blades.

@@ThrottleStopGarage no no no. Im talking the merge collector. The amount of time to set up the angles for the 5 tubes can literally be done in 2 minutes. In Fusion360 (which has a free version) you would make a single tube, set an initial angle and then make it a circular pattern of 5. It would set them each at 72 degs and you can then adjust the angles to where youre happy. After that, you can use the merge command to cut away each pipe where they intersect and even make a flat pattern of a pipe that you can print on paper and wrap around the real tubing. While having a 3d scan and cad model of the engine would be cool, most stuff can be done in small chunks that you iterate from real life back to the computer and back again. Think of the program as a piece of paper youre writing dimension in and it draws for you.

Like a log manifold? They package really well and can be made to work just fine. The guys over at Skid Factory use logs all the time. While a log style manifold represents a bit of a compromise for flow and scavenging, they've even been used in F1 lately. So if space is at a premium, size it up and it will work. The tube style where we're feeding individual runners into a merge collector are more efficient/flow better but are harder to package and harder to make. I wanted the challenge.

It's a 5 cylinder. 5/360=72. The rest is for the compound angle. The tubes splay.

Back purge prevents oxidation of the chromium, that and nickel make the black sugaring. This junk that forms is easily corroded, it isn't carbide precipitation . Most 300 series stainless is low carbon, dual certified. Carbon can add strength but makes heat affected zones sensitive. This is most important in dissimilar joining to carbon steel.

Thanks. The orientation of the cutting should not matter - but they do all work a little differently. 13º is a very narrow splay angle. This leads to a lot of welding, a long merge, and may be difficult to weld the runners into the merge. So the marking cap would have to be redone to reflect this splay angle difference. So yes - 114.5º is your angle.

@@ThrottleStopGarage, I would be glad to. I have already performed some calculations. I tried to attach them using a link to image hosting service, but the comment was deleted. But I will try to share what I've got in this comment: So, we have two angles that are known. 72 degree angle is located on transverse plane. 20 degree is located on longitudinal plane. And one angle that is needed to be found. This angle lays between two neighbour pipes. It also lays on the plane that is different from first two. This plane is inclined to longitudinal plane by 20 degrees and to transverse plane by 70 degrees (90 - 20). Let's call this plane A. So, the cut angle is half of the angle between the pipes. To find it, we will use the law of cosines. Okay. Let's say we have base radius R (from 4:44). We also have a right-angled triangle with lesser cathetus R and opposite to it angle equal 20 degrees. hypotenuse is our one pipe. We can find the length of the pipe by dividing R by sin20. Now let's lee another triangle in plane A. Two edges are equal R/sin20 as they are pipes. Now to find the angle between them we need to know the third edge. We are going to transverse plane (where 72 degrees angle is). Third edge also lays on this plane. And we have the third triangle. Two sides of which are R, the angle between them is 72, and the third edge is found by the law of cosine. This edge squared equals to 2R^2 (1 - cos72). Okay, now we can find the angle between pipes. We have all three edges of triangle on the plane A. Using the law of cosine again to find the angle: R is cancelled out as it should, target angle does not depend on the R if the proportion is preserved. cos a = 1 - (1 - cos72) sin^2 20 = 0.919 a = 23 degrees. And half angle of 23 is 11.5. Which is a little different from 10. Anyway, I just wanted you to explain the math that stands behind your division of 20 by 2.

It was about 1150 frames - some was cut - it took one evening to build the machine and shoot the frames.

I just got LPS CCF V3 and I need to make a 6 to one collector. I did the 360\6= 60. My cutting angle is at 12 degrees. 5” long schedule 10 stainless My rotation base on the math. 60-12= 48 Than 180 - 48= 132 is this correct ? Thank you so much I’m savage and for all The amazing content you put.

I can say that the math seems right - buy some 1.5" ABS pipe and cut it and test before you cut any steel. Then when you're confident, make sparks.

Why does this seem far more "collide-y" than your typical aftermarket header collector? Like, those (incl turbo ones) seem far more parallel than this. Is it just due to your chosen angle? Are there downsides to this type/advantages to the more parallel type?

The angle is all about packaging. You'd like to keep the angle as shallow as possible to help flow. No loss at this angle.

Was the stop motion a nod to Soup Classic Motoring? Also, why won't Certiflat sell to you?

Of course - George makes the best content on YT. CertiFlat won't sell to Canada. I got the positioner kit through Eastwood...drop shipped from CF - then they closed the loop-hole.

Very nice, but a little disappointed with the lack of funk music. But the tea was a good touch.

LOL - maybe in the next episode we'll get the funk out.

Will this work for a 4 to 1 merge collector?

If you use the same process, it will work for any number of tubes.

I've only made this 5:1 and 2:1 merge collectors. 3:1 is 120 degrees not including the merge angle. My advice is to get some plastic pipe and experiment until you get it to work.

Why did you have your cup on a metal surface it sucks the heat out of it and no one likes cold tea. As always great content and thanks for sharing

I drink it so fast, it doesn't have time to get cold!

That's the first time something remains unclear: WTF is a purge block? Does it blow argon or what?

Yes - it serves two functions. 1. A pathway for shielding gas to evacuate the air from the back side of the part and 2. it's a heat sink to keep warping at bay.

Level making noise? I wonder who is he referring to... BOM
