Im not sure on the rpm, but i would guess over 20k rpm. Plenty fast enougth to light an led lol.
A few suppliers make model drain cocks, decent price one here..
I buy the fittings for my boilers from 'cleavdon steam' he has a nice range of fittings at reasonable prices.
these little items are always quite pricey. im eventually going to convert a little lathe into a turret lathe and knock out batches all my own valves, water guages and safty valves. But thats on the ever growing list of corse.

That speed sounds about right, maybe a little faster, I estimate mine at about 30,000. Yes they should be able to drive A LED (ROTFL) ! more like a dozen or so.

Mine is at present lighting 16 100mW white LEDS in groups of four and could easily light 30 or more if I wanted to.

I expect yours will be not far off that, your problem will probably not be getting enough power but getting too much and blowing the LEDs. If you find this is a problem I have a simple regulator circuit that can cure it.

Best Regards Mark

Hi mark yes its easy to blow the leds, i use 10mm leds with a built in resistor for protection. They are about the best quallity leds ive found anywere. They run on 5v-12v
They have a diffused lense and come in a realy nice warm white color more like a classic incandecent bulb.
Pic here, the resistor is just visable inside the heat shrink.
