Back reinforcing strip
- Glue reinforcing strip made from cross cut strip taken from guitar top/front.
- Burr side up and overlap top and bottom ends on back and glue down. Won’t necessarily be a strip the whole length of back so glue a shorter strip if necessary. Hold down with masking tape.
- Clamp down using the clamping/joining jig for 5 minutes. Cover with paper to prevent wood from sticking to clamp bar
- Remove clamps and wipe off excess glue and re-clamp for 1 hour
Cutting circles for centre sound hole decoration and rosette
- 1.5mm router bit and special jig on router rotating round a 1/4″ pin. Set depth of bit to 1.5mm
- Drill 1/4″ hole into sound board according to centre hole in pattern. Used a bullet nail to put hole through pattern into sound board.
- Place piece of backing board (MDF) under sound board to uses to insert pin into.
- Drill through sound board and into backing board. Drill was too sloppy for pin so has to re-drill backing with new drill. Sound board hole was also a bit sloppy so had to account for that when routing
- Practiced routing concentric circles round sound hole on piece of MDF to make sure radius was set correctly
- Block planed edge of laminated white/black/white/black decoration for circle material
- Scribed 2mm side with a marking gauge set appropriately. Keep scribing from both sides until almost through to centre material then cut with a knife. Scribe kept going off line so need to do with care
- Put material into channels to make sure it bends. If it’s too dry it will break
- Put glue into circle channel and then press in beading material one circle at a time.
- Wipe off excess glue
- Get a piece of off cut that fits over the inserted inlays and clamp down on bench. Leave for an hour and a half to dry
Block planed and joined two pieces left from back and held together with masking tape in order to make rosette inlay next week.
