I would love to visit Prague some time. My son spent some time there and really enjoyed it. > Tim, I like your attitude very much - it would be good if it was more > widespread on internet discussion lists!

I make it a point not to stay in a thread I think is getting out of control and to exit as gracefully as possible. > Back to diaphragms - I see you have good knowledge in repair, what > have you found a best way to clean oiled blades?

I'm a hacker with modest abilities, not a skilled amateur and certainly not a professional. I work on some of my own equipment more out of interest in mechanisms and less because I'm good at it. I don't think there's an easy way out to cleaning an aperture diaphragm properly. IMHO, the best fix is to fully clean the blades the hard way, all the way to the source of the oil. An easy wipe down is probably only a temporary fix; but sometimes that might be appropriate. Like when I'm just too lazy. Ether is too volatile to be worth it. Isopropanol is okay, but I prefer to use naphtha as a solvent. Naphtha cleans better than alcohol and leaves no residue of it's own. It's flammable, but no where near as volatile as ether. In the US, naphtha is sold in tobacco shops and drug stores as lighter fluid for the old wick style cigarette lighters like "Zippo" (not disposable butane lighters). It's also sold in sporting goods or hardware stores as fuel for hand-warmers. Naphtha is also what dry cleaners use, so maybe you can talk the shop owner out of a small amount the next time you drop off a suit of clothes to be cleaned. So what is the best beer in Prague?
