Blur and Cheffy,
Thanks for the tips. I will check those site and see what I can find there. I'm going home soon and will take measurments... The only thing that I measured was the outside diameter of the male ferrule (0.279 in) that is close to 18/64. I measured at the closest of the base as I could get before it gets thicker (away from the tip).
Cheffy, yes this is the worst split since a tiny piece of wood is missing. But on the other hand it is not deep. It seems more to be scratched and not a split. The rest of the splits are normal ones and they are small (the longest is not more than 2 in).
I will ask more question as the work progresses. I have some experience wrapping graphite, but this is my first boo project. Let see how does it go.
