I totally wish these 2 alignment / scale tools were combined some way into one. Given a reasonable price I’d buy it today.

I have that tool, I work with just three scale lengths, so I measured from the end of the tool to where I would put the front edge of the 1 string for those scale lengths and marked the positions on the tool with a scribe. With a nut or nut blank installed in the neck I put the end of the tool against the nut and place the bridge with the scribed mark as a reference.

Yea that’s kinda what I did ... but man it would be cool if someone designed one that would be adjustable / be an all in one.

We know how important scale length is... and how important it is to get that bridge right in line with the neck line...

Btw I didn’t mean for this to be in the neck jig forum ha oops

The issue with the jig you are describing is it would have to accommodate various scale lengths. Also, how do you handle compensation? It gets complicated pretty quick. I designed a centering jig and that is straightforward because there is no need for variability on that part. I will go take a photo of what I came up with.

I’d assume the compensation would be handled by cutting the spot after the bridge was placed. Or maybe put some little spikes on it like the stew Mac doohickey

I have both of those jigs. Love the center finder when I'm setting a neck but don't feel that it is a great tool for setting bridges and I don't use it for that. I set the bridge based on a measurement from the the neck/body join or the 12th fret center. After the bridge is installed I use the StewMac jig to locate the leading edge of the saddle and cut the slot on the guitar. Combining the two would not be useful for me. Different strokes I suppose.

Here is my centering jig. I made it with hardware scavenged from a hand screw clamp. The two bolts are half right hand thread and half left hand so this keeps the posts centered. The jig is easy and quick to use, and I find it quite accurate.

I also made a small device that slides on the centering jig to locate bridges, but I don't use that very much.
