In any other industry manufacturers and distributors of hardware components would make CAD drawings of those components available, so designers wouldn't have to waste their time drawing these things from scratch. For some reason this is not the way it works in the stringed musical instrument business. Maybe there just aren't enough designers using CAD software? Stewart MacDonald has been heading in the right direction, putting mechanical drawings of some of the components they sell in their catalog. In any case, here are the drawings for some of the components I have for you to download. All were drawn by me and could contain errors. All are in zipped files containing AutoCAD 2000 or 2004 .dwg and .dxf formatted files.
Check out the page containing tips on using the CAD drawings for more information. Let me take this opportunity to encourage hardware and component manufacturers to make CAD drawings of your parts available. If you don't want to make them available on your own website, email them to me and I'll put them up here. And if you are an instrument designer that uses CAD software please consider sharing whatever drawings of hardware you have with others. Again, if you email them to me I'll make them available here (and heap you with credit and thanks). Thanks.
Don't forget to check out my Instruments Page for complete downloadable instrument plans.

Double bass tuning machines, double bass end pin, bass bridge adjuster wheel, a scalable scroll spiral outline and a very nice Strad style ff-hole. The scroll spiral was copied from a violin using quarter turn arcs. It is not scaled to any particular instrument but can be scaled to suit any of the violin family instruments. The ff-hole is also not scaled to any particular instrument but can be scaled to suit. This was drawn from great instructions by Robert J. Spear which appeared in the second part of an exquisite three part article on drawing the violin in American Lutherie #94.
Various electronic guitar parts including pickups, jacks, control pots, selector switches and a Gotoh battery box.
Gotoh and Fender electric bass guitar machines and Gotoh guitar machines.
Manufactured bridges and tail pieces for guitar. Just a top mounted hardtail electric guitar bridge and a Danelectro intonable guitar bridge now.
Strap button, Fender neck plate and Stewart MacDonald Hot Rod trussrods.
This file contains top and side view fingerboard drawings for various standard guitars and basses. Each drawing contains 24 frets (remove what you don't need), dot markers, strings (top view), and a proportionally spaced nut. Please let me know if you'd like to see more of these. Also in this file is a simple 1" fret scale. What can you do with this? Using the Scale facility of your CAD program you can scale this up to whatever fret scale you need.
