Please if anybody else would like to put in theie 10p worth then please
do so.

At Hobby Holidays, as a small company we try to do whatever we can to
help our customers. To that end we will make the spigot on the end of
the Mock (False) axles to any size possible.

About 90% of the 4mm jigs we have sold have been 1/8" axles with 1.5mm
ends, which is the size of the bush that fits over the 12BA screw which
passes through the wheel to act as a crankpin. This is the standard
size for Alan Gibson, Ultrascale and Mike Sharman. The old style
Romford, now Markits, where you solder a thick brass washer onto the
crankpin is 1mm. The new Markits one is I believe 1.67mm (can anyone
confirm?)

7mm is a little easier 3/16" with a 2.4mm end, as every crankpin I know
on the market is either 3/32" (2.38mm) or 2.40mm (Less than 1thou"
different.

I hope that Helps regards Phil
