I began the restoration of my machine. Dismantled it, polished all the brass parts and it looks great. However there are a few problems with the unit. Bought this item on ebay and never received something with this many problems, I guess I paid for a home project.
1. The piston assembly is a mess!
I am not sure whether I should try and repair this one or get a machinist to lathe a new one in brass or bronze.
2. When I opened the base I found that the thermostat switch was rusted and will not function anymore.
I am going to try and find some kind of temperature switch that will stay on until the boiler reaches a certain temperature/pressure and then cut power, and another switch that will override this and heat to a higher temperature/pressure for steam. I am not sure at what temperature the power to the boiler should be shut down for brewing, and at what temperature it should be shut down for steam. Also I would like to create a safety temperature relay in case the power is left on. Seems there was none on this machine and I imagine that this could be a fire hazard. I guess this was fine back in the day.
Any suggestions will help as I am a sculptor and not an electrician. lol. Actually I also have a degree in building engineering/civil but have worked as a sculptor for the past 15 years.
3. I am going to need new piston gaskets.
Anyone know where I can buy these gaskets? Does some company sell them when you specify the size, shape, material, etc.
