If you are doing a non-pyramid bridge, the first couple of jigs will still be handy. Here is a Brazilian Rosewood bridge I made for a 1933 Gibson L-00 that was shattered and that I rebuilt. The saddle wasn't cut to length in this picture, and I wish I had the pin hole and the saddle slot jig earlier for this one. There are many designs for both of these jigs and I did ones that made sense to me and the number of bridges I will ever make.

1) Time to locate the bridge. I made a fixture that lets me bump the installed saddle up against it, center and square it, and off you go. Here is the nut end - it just hooks over the nut slot

2) This is the business end - I made it for a 24.9" scale and am using the convention that is confirmed by the StewMac fret locator calcs. Confirm the scale by measuring first to twelfth frets on the actual fretboard, double to get scale length, add .1 inch to compensate the high e, then angle the saddle 3°, or 1/8" from e to E. Then subtract 1/2 the thickness of the saddle blank - 1/16" for an 1'8" saddle - to put the point of string contact in the center of the saddle - make the fixture that long. Now when I bump the saddle against it, the bridge is in the right place

3) Except that this time I am using a 25.4" scale. I added a .44 (if I recall) extension to the fixture and now it works for my new scale

1) Clamp it on and center it . . . .

2) Center the bridge side to side and begin to tape it down. . . .

3) Check for square against the center seam, tape the heck out of it. . . . .

1) and drill the outer two holes

2) Painful alert - we will never speak of this again. I positioned the bridge with the wrong side of the saddle against the jig. I found it when I shined a light down from the top and checked with a mirror inside to be sure I hit my bridge plate - I didn't

3) With a piece of sandpaper on the top, I arch the bottom of the bridge to match the top curvature. Ready for finish (except for patching 2 holes in the top!!!! GAHHH)

I have a top with 2 holes in almost the same place, for the life of me I don't know how it happened, needed 2 extra pegs for that guitar.
