I needed my 7" fan for something else (They don't seem to sell 7" AC fans these days.) so I got out one of my father's fans for use at the computer. It's a Bersted 1250R "Zero" model, made by McGraw Hill in the 50's they say.
1) I couldn't find my regular oil, so is there any reason not to use 10W-30? It never gets that cold in the house, especially in the summer when I use a fan, so I figure that's 30 weight. Good enough, right?2) So that leaves the detergents. They're not something that actually has any effect at room temperature, are they? I figure they work when the oil in the car is hot. (How hot is that?)
3) Then the fan made some noise, and it was clearly from the metal blades, not the armature. Is there any way I can stop the noise from the blades? Could I tie them to the protective screen, for example?Mine looks a lot better than this one, and has the original cord.
