Acoustic Guitar Construction

Jim, it would be nice to be able to profile the whole pin at once with the file method, but you run into issues with that.

First issue would be you would need to hold your material either at one end while you scraped the pin and that leaves quite a bit hanging out of the holding device. Also your material for a single pin would need the extra length for you to grab it in the chuck i.e. say an inch for the pin itself and another inch or so just to chuck it solidly.

Secondly scraping the full length all at once will submit a lot of cutting pressure on the cutter and more importantly on the pin itself especially at the unsupported end. And the file you need to carve the profile onto would have to be that much wider as well.

I have attached a photo of a taper or peg cutter ( Making Musical Instruments , Strings and Keyboard - Edited by Charles Ford - Pantheon Books - 1979) that is used to shape the taper quite like a pencil sharpener. This method is ancient and violin and viol craftsmen make them using a device like this.

I hope this helps you a bit.

Best regards,
