To make your own Timing Disc to suit your bike Vincent or other bikes it has adjustable settings go to: https://www.blocklayer.com/degree-wheel.aspx you can pick your own size disc- valve opening and closings degrees then you can glue it to a CD or an old record depending on size: I took this from the FB Velocette page put on there by Rob Morris but I am sure they will not mind us borrowing it can make setting/checking your Ignition and checking the valve cleances a bit easier .... sorry boys and girls if this has been posted before

I suppose all most of us need is a 1/4 of a disc 45 deg BTDC to TDC thats certainly all I need nowadays

Except, you need ~90 deg total to be able to use a hard stop in the spark plug hole to accurately zero it. However, since with a hard stop you'll have to swing the engine through almost 360 degree anyway, there has to be sufficient clearance for a full disc even though ~270 degrees of the disc is wasted.
