What type of engine is this for by the way, It looks like a small mower/go kart carb, were you doing this for practice or actually trying to increase power? I'm curious what kind of power gains could be seen in small sub-10hp engines :)
To my knowledge like the author stated, it improves efficiency by making the surface the air goes through smoother, creating less turbulence from micro-pits in the metal.

Be careful with using non-vacuum oils in pumps. Vacuum pump oil is a specific type of oil, a low vapor pressure oil. https://en.wikipedia.org/wiki/Vapor_pressure Regular oils are formulated for operating at regular atmospheric pressures, but might outgas, or release vapor when the pressure drops too low. Vacuum pump oils are formulated to not outgas even at extremely low pressures. While conventional oils may "work" in vacuum pumps you may find it will not reach as high of a vacuum as it could with real low vapor pressure oil. Conventional oils can also become more flammable at low pressures, and can combust. In terms of cleaning water out of the oil, you may be able to get away with pouring the oil over a desiccant like silica gel, the silica gel will trap the moisture, and p...

Conventional oils can also become more flammable at low pressures, and can combust. In terms of cleaning water out of the oil, you may be able to get away with pouring the oil over a desiccant like silica gel, the silica gel will trap the moisture, and possibly you may have cleaner oil, I gues depending on what the operating temperature of the oil is, you could try to heat it a little and evaporate the water, but use this as a last resort, and don't boil the oil. Hot oil is dangerous to be around.
There is nothing I love more than neat wiring, reminds me of the 3d pipes screensaver :)
Yes, one pin goes to the cathode on the tube, but we are using it backwards, using the cathode as the anode. The anode of the tube is the big nib on the top of the tube, but we are using it as the cathode.
Indeed, I also recommend adding some oil to the inlet of the pump to provide some lubricant, since it will slowly spray oil mist out the discharge side.
I use pin 1 on the base, which is the cathode pin. In reality though, since this is a cold cathode x-ray generator you can use any pin that connects to internal metal structure, it's mostly about just having a large voltage potential across the tube with a gap in between. Any vacuum tube that has a large gap will emit x-rays at high enough voltages. The pins would only matter if you were using a hot cathode tube, where you have a low voltage high current that heats a filament, and a secondary high voltage to accelerate the electrons that come off the filament.
I tried to make one of these from a spoon I found at an antique store once, but when I attempted to anneal it, it just got brittle and broke. How do I tell what material they are on the go?
Awesome! Iv'e heard of people using propane tanks for charge air tanks before with good results, but you would need to install a drain at the bottom at the very least.
Sweet! be sure to post pictures here when you finish it! I recommend if you need high CFM that you use more than one pump, that way you can run air tools. :)
I didn't even think of that, the whole house units would have much higher CFM, I will have to keep my eye open for those.
Yea, I mostly just put that there as a disclaimer since it's so harmful to the environment. Where I live you can be fined up to $250,000 for intentional CFC releases. I believe you are correct also, most modern refrigerant loop appliances have a non-CFC refrigerant, but since this is a recycling project, most appliances you come across in the trash are probably charged with r12.ps. everyone needs large volumes of hair, that's why I use Garnier Fructis® for luscious, voluminous hair! ;3
It is an absolutley gorgeous design, where do you get spoons like that? Antique stores?
Could you include a link to your etsy page? I really like that design, what kind of spoon is it?
