Minibass: cutting the neck pocket and drilling the string anchors

We’ve had intermittent heavy showers today so I haven’t made as much progress as I had hoped. First job was to cut the neck pocket, so I made myself a routing template. I clamp the neck to the MDF and draw lines along each side, extending out onto the board so that I can draw on a centre line. This means that when I match it up to the centre line of the body everything matches up.

I then sticking a couple of guide pieces either side. At this point I unclamp the neck and tap it down into those two guides to make sure it is really snug. I then stick down the end guide.

A few passes with the top bearing cutter to follow those guides, cutting into the MDF sheet below and I’ve got a template that matches the neck dimensions.

The neck pocket needs to get routed in at an angle, so I set up a pair of guide rails, and chock up the back egdes to get the angle I want (a rise of 30mm over a distance of 600mm). The neck pocket template gets secured to the rails and the body flat to the bench below. Rout the pocket to 13mm deep at the front edge and we’re done.

While it was still off the body I trimmed the back of the neck to start the job of carving the profile. The real work on this won’t start until it is glued to the body, so I can shape the neck heel at the same time.

Last job of the day was to drill the holes for the string anchors. I drilled 2mm holes all the way through the body in the positions where I wanted them.

From the back I drilled 10mm holes to for the ball-ends to sit in. These are much bigger and longer than a traditional ball end so these holes are 18mm deep.

Back to the front and I drilled holes for the strings to pass through – these are matched to the individual sting gauges. Sizes are 5mm, 4.5mm, 4mm and 3.5mm.

And this final shot shows the yellow ball-ends seated in their “pockets”.

Next job is to rout the control cavity and then glue the neck on. Once that has been done I can do an initial assembly and rough setup to correctly intonate the bridge. I’ll disassemble, glue the bridge into position and then it is onto shaping the neck, sanding and application of finish.
