The last few days I worked on the cavities to convert this body into a semi-hollow one: designing, sawing and smoothing the template and routing them.

I did it with a router and a template guide, layer by layer (about 1 mm each time). Then, I used my template bit with ball bearing to do the edges (since my template is 1:1 size).

It came out very nice and the weight dropped like alot! Also, the sound changed remarkably when I tap on it. Much more percussive and acoustic. I’m very curious how it’s going to sound.

When I finished the body and picked it up I immediately thought I should do another cavity in the upper horn to get better weight distribution… So the next day I routed the extra cavity and it feels much better now!
