    Monotube Flash Boiler Design

    Forget above windshield washer suggestion. I did some further research and think the following is closer to your requirement. I do not know how to post a link but Google Amazon.com and enter in Amazon search "12v car washer pump kit' . They claim 135 or more psi and 80 to 100 watts and 1 to 5...

    Monotube Flash Boiler Design

    Why not try an automotive windshield washer pump? They force a pretty good flow thru the washer jets so they might have enough pressure. Certainly suitable for water.

    The North Pole

    The answer is pbvious. You have a Tates compass. They marked their needles backward; which gave rise to the expression "He who has a Tates is lost".

    Today I went to buy a file---and---man---

    Does anyone have a comment on, or experience with, the old technique of sharpening files by soaking then in acid? I seem to recall it was phosphoric. I have never tried it myself. At today's prices, it might be worth looking into. Years ago I bought files from the Boeing surplus store. they...

    Nice coil and ignition

    Thanks dsage. I think I will just be able to use the transformer, board and transistor; and drive the base thru the points and a resistor with 4v battery voltage. Only the heavier primary coil will be used. this is exactly the Bill Schmidt circuit. I am travelling now and will not be home in...

    Nice coil and ignition

    I have just discovered this thread and have 5 of these kits coming in the mail. Would you believe 5 for under $10US delivered? I am not an electronics guy but it looks to me like the spark frequency is determined by the puncture and recovery of the UF4007 diode triggering the thryistor. This...

    Electronic glo-plug ignition?

    I am surprised no one has mentioned "idle bar" glo plugs that we used in the early days of throttled/exhaust restriced glo engines, when fuel/air mixtures were not well regulated, and engines riched out at idle. The concept was a platinum? bar across the bottom of the plug to retain combustion...

    Sight glass for fuel tanks etc

    Slightly off topic, but has anyone posted use of common household sink downers for tank main bodies? Nice thinwall brass 1.5" dia., various lengths, cheap and available. Nowadays unfortunately many of these are chrome plated.
