    Stoked to see a new update on this! It's crazy how much that CNC machine can accomplish, even when its limits are exceeded. Was wondering the last week or so where you had gone, glad you finally accomplished this leg of the journey! Can't wait to see all the guys get together on this thing, even if it's just for troubleshooting lol

    A tip I have for cutting the circles, score it with the cnc and trace it with your plasma cutter

    Stainless steel work hardens very easily always keep it cool and move slowly (both speeds and feeds). Also the coolant not only acts to cool the bit and workpiece, but is used to flush millings away.
  • Not to be that guy, but after sanding you're feeler gauge was not 15 thousandths it was 15 ten thousandths or one and half thousandths. Anyways looking good.

    I spy a jetstream in the background. I too dable in the mini boats and im down in FTW. Maybe ill see ya out on the water come poker run wknd.

    Thats a real exhaust! But theres always a but - no vibration decoupling? Usually you do a part of the exhaust as a rubber or silicone joint so the engine vibrations dont transfer to the hull and wreak havoc there.

    Hopefully an expert stainless welder will chime in. Ive tried it a couple of times and I was far worse then you!!! so Kudos for what you got down. Im curious if you had fed purging gas inside the tubes if that would have helped. Experts????
