To complete the picture I would like to say that obviously I also use steel pins for plates positioning, made from the cylindrical part of drill bits of the same diameter as the one I use to make the holes (1.75 mm) for a perfect match.

The diameter of the toothpick is a little bigger (1.85 mm) so I reduce it with a scraper to adapt it to the hole and of course  I cut the pointed ends making it cylindrical.

Thanks for posting this photo. Guess what I will be doing this weekend? B)

+1 for toothpicks, the cheesier the better. Ebony is just gilding the lily...

Like others, I use sharp metal pins at first (read Hargrave's "The working methods of Guarneri del Gesu") but replace with toothpicks during assembly. As for cracks caused thereby, haven't had that issue, but someone has to keep the repairers/restorers in business, no?:
