Dirty banjo tube.
I met a great guy online by the name of Barry Jarrett.
He owns a shop named Riley's Coffee & Fudge (www.rileys-coffee.com).
He had a used banjo bolt from an old machine that he sent me.
Pressure test.
Before I mounted the steam boiler back in the chassis, I wanted to test it for leaks.
I hooked up all the pieces necessary to make it a closed system and pumped it full of air with a bicycle tire pump.
There was a leak at the boiler and the T-fitting that feeds the pressure switch and steam pressure gauge.
I ended up using a special food grade thread sealer from Loc-Tite to keep it from leaking.

PID modification.
I decided to do a PID modification to this machine.
I replaced the mechanical temperature controller with a thermocouple, Fuji temperature controller, and a solid state relay.
I mounted the relay in the bottom of the machine on a piece of aluminum angle stock that doubles as a heat sync.
