Making a semi-hollow neck-through winter bass guitar

The second guitar in the four seasons series :) This time it’s a necktrough semi hollow design made from maple and smoked oak veneer. The theme is winter so we took a snowflake and white color as main motifs in this build. It took quite some time to get the design right but after couple of work days the 3d model was complete and we could start the production. The 5cm plank was first cut to desired smaller pieces. each piece was than planed 43mm thickness and glued together into a single block. Glue we used for this project was vinyl acetate based with short open time of 20 minutes. After the glue has cured, the block was left for a week to relieve some possible inner tensions and to achieve uniform moisture level troughout the cross section. The block and the fret board was milled on kuka kr 150 industrial robot. Tension rod is made from two 4mm round cold rolled steel rods, one 4mm inbus screw and eight 4mm nuts. Fret slots were marked with a blade over the paper with precisely printed fret positions a
