S907_Express CNC work...

Last night did the first run on a neck profile. Not a full neck profile carve but a neck blank that is flat on the back. This way I can still carve them by hand (my favorite part of building along with top carving).

The idea is to replace the thickness run using the neck monster and the profiling run using a template on the router table. The router table was always the most nerve racking as you never knew when you might get horrendous tear-out and when you are doing 20 necks in a row it was no longer fun.

The first run went pretty well. I have to fix some feedrates and DOC (Depth of Cut) but it was overall very accurate and pretty fast.

With the CNC I can easily produce a blank that is .512 in thick from the 1st fret to the 15th. If I am careful while carving and stay off the back of the neck (the trussrod slot is .387 in deep) I can easily produce necks that are .748 in (18.9992 millimeters) thick (without frets). This is going to save me a lot of time and headache.

The heel tenon is now always going to be the same depth. I always try to get them the same but sometimes I just had to wing it… not anymore. I think I am going to like my new level of accuracy.
