Hi Ned, Yes - End pins are good. Normally a lute bowl is built with an end cap on the outside - so the end cap plus rib behind it is probably the best part of 3mm thick. In addition, though, there usually a similar piece of wood glued INSIDE the ribs, so assuming that's of the same thickness as the rib material, you should have 4 or 5 mm of thickness. The good thing is that the rib grain and that of the end cap and liner are at right angles to each other - like plywood - so there's not much likelihood of splitting it by accident.
Have you any way of contacting the maker? If so - ask him or her. I normally drill an undersized hole for the pin and then ream it out gradually until I get a good friction fit for it. Hope that helps.

One of my 8 c instruments came missing the end pin, but with a hole where one obviously was. Using wood from the handle of a small oil painting brush, I was able to fashion an end pin that has worked very well being held in by friction only. A second 8 c instrument was built without an end pin, and I would like to install one. I will have to drill a hole. My concern is that this instrument is of extremely light construction and I don't know if the thickness at the bottom of the bowl will hold a pin either by friction, or if there's thickness enough to hold a glue joint. Any suggestions would be appreciated.
