Do any of you have hands on experience with the top deflection gauge from Stew-Mac? I just saw it in their catalogue. For $69, it's tempting me. According to the instructions, you can also use it as a gauge for measuring neck relief. Feeler gauges are fine, but it would be nice to just dial it in.

The new SM neck relief guage is easier to use to measure neck relief with the strings on and under tension. Why not buy both? I did..... [:Y:]

Let's see,

dial indicator - $10 @ MSC
scrap aluminum - $5 at metal supplier.

Hmmm.......after my experience in making the cnc, I know that all this is cheap, and easy to machine. So for 10 minutes worth of work, and maybe $15 in materials, you can have the same thing.

It IS however a nice jig, and if you don't feel like making it, the price isn't too bad.

Don, I started thinking about that as soon as I saw it. How would you mount the dial indicator to the cross beam?

One idea I had was to drill out some baltic birch ply and hold the dial indicator in place with a set screw.

They do make plastic thumb screws that would work pretty well. Should be able to buy them from McMaster Carr or MSC. If you use a regular set screw you're better off if you can stick a small copper or brass plug between the set screw and the indicator housing.
