Braces and Neck

This weekend I put the radius on the braces, when clamped to the back, these braces will pull the guitar back into a domed shape. Its a slight radius (about 25') but it helps the back adjust to changes in seasonal humidity which might otherwise put alot of strain on the back/sides join.

I did this by making a curved template and then I used a plane with a spacer on the back end of a block plane to create a radius. The spacer angles the plane such that it makes the bottom of the block plane tangent to the curve of the braces. As more and more is taken off, the braces take on the radiused shape.

For the neck, having glued the scarf joint and the blocks that make up the heel of the neck I cut the truss rod channel. I'm using the LMII standard truss rod that requires a 3/16" by 3/8" channel. I cut this with the table saw. I messed up though, as the blade cleared the fretboard area, I partially rocked it up so it made a nasty little cut down the headstock. I managed to sand this out but it left the headstock on the thin side.
