I have another question. I put this here because if I can, I'd like to build a compressor with a tank and everything with this. I have an Eaton compressor off a 77 Ford 351M for the air conditioning. I can turn it over with a wrench and put my thumb on the end of the discharge hose and build pressure so I'm assuming that its still in good working order. My question is can anybody tell me anything about it? I tried searching for what was stamped on the little tag on it but got nowhere. Would this work good for a compressor to run tools, fill tires, and such? Could I use a lawn mower engine or would I have to get a smaller electric motor? And any ideas for a tank. All I have at the moment is a 680 liter oxygen cylinder which I think might be a bit small for this thing . It would be nice to have it gas powered then I would have to worry about having a place to plug in it at. Hear's a couple pics of it.
