Red Rimshot Posted April 11, 2020 Share Posted April 11, 2020 Hello all, can someone please tell me the thread size for the screw that holds the points cam to the crank please. The one I thought it was is a bit tight in there and I don't want to force it. Thanks all, Kings Quote Link to comment Share on other sites More sharing options...
wdbikemad Posted April 11, 2020 Share Posted April 11, 2020 I can't remember the thread Kings, sorry. But I can remember that I had to try umpteen screws from my spares stock before finding one that fitted ! Hitchcock's should be able to help as they are still open..... Other alternative may be to have a fiddle around with a spare crank assembly and see what fits ? Quote Link to comment Share on other sites More sharing options...
Red Rimshot Posted April 11, 2020 Author Share Posted April 11, 2020 Hello, it measures out at 7/32 bsw, but that's an odd size. You can buy taps n dies but no screws. I've never got my head around the whitworth sizes so I'm wondering if it's 3/16bsw - I'll check tomorrow as I have some bsw taps. Hitchcocks - it's not available. The annoying thing is I had one, yes got to check my spare cranks. Took a pic of the 'Airborne collection' today. Thanks Quote Link to comment Share on other sites More sharing options...
