It's been a few months, just wondering about the Tungsten experiments. Are there any updates? Why not just put a real bearing on the shaft/connecting rod? Or is the Tungsten also adhering to the cast iron cylinder wall?From what I've gathered in my research the main enemy is heat, and YT videos indicate that most of it comes from the lower cylinder. I wonder if it could somehow be "misted" with a cooling mist, similar to how the second stage is cooled with a water jacket?
Well... The YH overheated today (motor, not the head) and stopped with only 3500psi in the tank. I took the housing plate off and discovered that the fan inside the YH was about useless for drawing off the heat so I am going to cut about 75% of the cover off, leaving what is needed to support the compressor/motor and use a highspeed fan (12,000 rpm) to cool the motor casing instead. The design is just silly and there are literally no air passages inside the unit to get air moving across the motor casing so it's bound to shorten the life of the compressor. If I had expanded metal and a brake, I would fab a cage and use two opposing fans on the sides. I'll post pix of what I come up with and no, I would not call it "safe" with no cover.
David - Is the fan still blowing air on the motor, or did you reverse it, so it pulls hot air away from the motor?
