Dual Exhaust Modes

[Kaptain Krunch]

I checked out mcmastercarr and couldnt find anything affordable in steel ball valves, there were ones that could hold up to 450* + but they were $55 for a 1 inch one.

To build mine I looked at every picture of electronic exhaust cutouts that I could find, then made it out of aluminium. If I was to do it again I'd made the central pivot out of stainless rather than brass (I had some... it wasn't a good choice of materials).

I used a milling machine with dividing head to produce the housing so it would seal, and I used a lathe to make the rest of the parts. The motor is a 24V DC Gearmotor from a coffee machine, lol.
