After selling my first instrument I earmarked that money for various things to offset the cost of building my instruments. I bought tuners, pickups, and tools and the biggest purchase I made was for more C clamps.
I had bought some really good quartersawn red oak and it had just been sitting there leaning up against the wall and I finally ripped it and made neck blanks out of it. I had some slab cut maple that I ripped and laminated to orient the grain on the quarter and placed a decorative cherry strip in the center just to get me to the width I wanted. I had noticed on build #5 with the Fender style bridge that the string spacing made my strings a little too close to the edge further down the neck.
I won't be trying to build 10 guitars at once, but I know a lot of times is consumed in the neck, so I just got a lot of necks set up for future builds and two of my next three instruments are going to be based on my fretless Punch.
