Morning folks,

The discussion about the peculiarities of Whitworth 17/64" X 25 chainring bolts/screws for Chater Lea chainsets got me thinking about the need to find a good gauge or set of gauges to determine such things. Any suggestions?

BTW I lost out on the bidding for the bolts on EBay - guess I am now going to have to turn to my mate Derek. Just out of interest does anyone know of a supplier of Whitworth dies - a quick Google search showed that a 17/64 X 25 die can be obtained (borrowed?) from the London Douglas Motorcycle Club! Maybe worth a membership???

Boy do I miss having Sheldon around!
