Well, the pins were originally very crudely made, and I'm not so sure they (when the procedure was established) had rounded tops. Some time ago I restrung a European "Boutique Piano" (to borrow a term I heard used by Horace Greely years ago). The client opted for all OEM materials, so we ordered bass strings and bridge pins from the manufacturer. They invoiced me for bass strings and "bridge nails" (!!!), which turned out to be an accurate description (less the head of the nail, which had already been removed by some distinguished "guest worker," no doubt, thus elevating it from an ordinary nail to a pricey GERMAN nail!). Needed filing--or I guess I could have used little plastic caps :-)--to make the end result look anything other than downright funky.

Well, the pins were originally very crudely made, and I'm not so sure they (when the procedure was established) had rounded tops. The bridges were, and still are as far as I know, hand drilled. So, given nasty looking pins and holes of random depth, the obvious way to make them look neat is to drive the pins to the bottom of the hole and even them up with a file on top. I think it's a manufacturing expedient, lowering the skill level and time needed for installation. Ron N -------------- next part -------------- An HTML attachment was scrubbed...
