    I used to see lots of that when working for a fab shop, that is caused from weld stress, you could bolt it to a flat surface and put it in an oven for heat treatment to remove the stresses.

    Jim Scott and I 50 years ago made very sophisticated 180° headers many of them for many cars. A lot of engineering when it came to equal length and keeping the runners the exact square inch in any part of the sections and limiting the number of welds and keeping the penetration low and so many other things. I’ll have to say watching these headers being made is the very best work I’ve seen yet. Congratulations.

    Yo Rob, what was the paste that you applied onto the flange at end of the video? I assume its similar to anti seize but the color is throwing me off. Thanks!

    • Alex Stover
      Alex Stover

      taking a second look, is it a paste form of the copper spray? What would be the reason for applying it? Is this setup gasketless?

    Hey Rob i remember your turbo blanket video, now that Isaiah made the bad ass manifold you should do a video on heat output on the exhaust again, 1st test regular exhaust with turbo, 2nd test ceramic cote the exhaust header and turbine housing, 3rd test turbo blanket and header wrap on the manifold. I would love to see the 3 results how much less underhood temps you get. DO IT FOR SCIENCE ROB!!

    rob you need to get a honing and surface grinding table it makes sure things you machine are perfect and flat

    Why hasn't Isaiah started a FIshows channel called "Welding Prawn" yet?

    If you have issues with flatness, it’s a setup issue. When you clamp it down, you need to check for flatness and shim as needed. Otherwise, buy yourself a surface grinder. Setup is 95% of the machining process

    I was apart of a project where we did a CFD of high volume water flow with many 90s and it was more about the turbulence that it causes at the 90 and you have low pressure water that can make it's way back down the bend and reflow up. That will also contribute to the extra heating at the bends with air flow in this case

    Wish you would show more of Isaiah working, he is a Hell of a fabricator. Your lucky to have found him. Is THAT what you wanted me to write Isaiah? No I'm NOT related in any way to him😉😉.
