    Hi Martin,

    Mark - yes, you can apply tremendous downward pressure before twisting the clamp...
    Not with the vintage one Mark (Dingdong) has bought, you can't. It ain't hollow underneath

    Martin, I wasn't planning to apply huge downward pressure. There is a teflon pad on the bottom of the bearing. I'll keep an eye on it to make sure it doesn't get damaged.

    I was thinking that I'd need a tungsten lamp, that flickers at 50Hz, to see it properly. I guess there would have to be 50 and 60Hz ones depending on country, but maybe I'm wrong about the lamp thing.

    Could someone with the felt washer please measure its approximate thickness and diameter? I've been using a modern Michell clamp for a few weeks bought cheaply off ebay - but it didn't come with the washer.

    Any bulb running off the mains will provide the 50 Hz 'flicker' you need to read the strobe and yes, there are versions of the strobe for 60 Hz.

    Do those modern energy saver bulbs flicker? I guess I'll find out.

    Another thing you might need to be aware of if you're considering one of these, is that you need a 'special' if you want to put it on a Rega - different spindle length y'see. They're available freely enough, but don't think about trying a standard one.




    PS Mark - don't worry about forgetting my name mate, I'm crap with names & I'd forget mine if it wasn't on my driving licence!

    Yes, but it can't be guaranteed to be 50Hz from the mains as it alters during the day & night according to demand. Admittedly over a 24Hr period it has legally got to be 50Hz to keep syncronous motors accurate in clocks, but on a smaller timescale it can vary from lower than 49 to over 51 Hz
