Cutaway Fitted and Back Kerfing Done

Posted by Brian Goode on June 3rd, 2007

I got the florentine cutaway joint fitted and joined (with a structural epoxy fillet), and the reverse kerfing glued in on the back. Next I’ll do the front side kerfing and neck and tail blocks - then the sides and rim should be a pretty stiff structural unit.

Sides are in the Mold!

Acoustic Bass Guitar sides in the mold

I got the mold glued up last night, and today I got the ABG’s sides trimmed and in place. It sure is nice to see that asymmetric taper in person - it looks just like the CAD model! Next will be to fit the sides together at the cutaway and install the kerfing. I got reverse kerfing for this project, which should add some nice stiffness to the sides.

Gluing the Mold

Posted by Brian Goode on May 27th, 2007

The picture says it all here. My initial idea had been to bolt all the layers together so it could accommodate instruments of different side depths, but it turns out my drill press doesn’t have enough throw to make a straight hole that deep. After several frustrating attempts to drill holes for the bolts, I decided to glue all the inner layers together and screw the last top and bottom slices om. That way I can still access the edges to clamp the kerfing.

Home-Made Router Table

Home-made router table with acoustic bass guitar mold pattern

I built this extra-large router table to trim my mold slices flush with the master pattern. It’s basically just a board with a hole in it and a router mounted to the bottom. The whole mess sits on a couple of custom sawhorses that my father-in-law made for me - they fold up flat when not in use but will hold a full 4 x 8 sheet of plywood.

Update: Everything’s routed…

Mold Progress

Plywood acoustic bass guitar mold slices.

I got all the new acoustic bass’ mold slices bandsawed out today - it’s finally starting to look like a body! Now to trim them clean on the router table and put them all together.
