One of the challenges of building a guitar from the
ground up is that there are many, many opportunities to make one small mistake
that turns many hour s of work on an instrument into many hours of work on firewood. Building and shaping the outline of the body
has been an exciting and enjoyable process, but it’s also the one part with a
HUGE margin of error. I could cut one of the horns off and bore a 2” hole n
ear the tail and it wouldn’t make a bit of difference in how it sounds through the amp when it’s done. But if the neck pocket is too big, the neck joint will be sloppy. If I carve too much of the neck, it may not hold up to the tension of being strung. There are some things like this where there is literally one shot to get it right and I really don’t want my first time doing some of these things to be with the wood that SHOULD be the final piece.

This project started out on a recommendation from
one of my mentors to NOT use top-quality lumber for the first pass, but to take
my first run using a cheaper hardwood, such as Poplar (which I did). Taking
that to the next step, even though my $13 Poplar body isn’t made from Walnut or
Mahogany or something ridiculously expensive, I have quite a few hours into
taking it from a slab to a guitar body and I’d rather play it around a bonfire
this summer than fuel the bonfire with it.
So I made a decision to hack together some pine boards and make an
initial pass as constructing the neck and machining the pockets for the
pickups, control cavity, and neck pocket.

Rough outline, half-shaped. |
But what do I actually DO with this? I can’t chop the headstock and heel off to trace the profile and I can’t make a sanding jig since the profile changes as you move down the neck. About all you can do is mark the depth of the vertical from the fretboard (basically the bottom of word “Reissue” in the images, above), cut the neck to a its depth (taking into account the fretboard thickness), and just start hacking away at the edges with rough wood working tools to get down to the point where finer & finer tools can be used to smooth the neck to a general profile. The nice thing about working with pine is that this went very quickly. The lousy thing about working with pine is that it’s SO soft that it rips and tears easily, but it does offer a lesson in taking the time to do the work at the pace the wood wants to work at and not try to force the pace.
Drawn outlines of cavities. |
I
definitely went into the Pine Neck project with a lot of questions and came out
with a quite a few answers, or at least directions. The Pine Body project was
more straight-forward and there was less figuring out to do. Coming out of this exercise, the key pieces
of learning is that the neck is likely going to be the part of the project
where I can’t realistically get a quality product with the tools at my
disposal, so I’ll be spending time down with my mentors making the neck. I’ll also need to do the bulk of the body
routing/drilling work there as well.
Although I could easily do the cavity drilling with the Ryobi, getting
the neck pocket right is going to be a critical part of the construction and
something that would be unwise to attempt myself.
Well on your way to discovering the joys, intricacies, art and disappointments of instrument building. Forstners, yep but that's just the tip of the iceberg. Joiners, planers sanders decent chisels, routers, hand saws, rasps, hans planes and the the new shop to safely house them all in.....or, you could do the shop and get a CNC, but that would be no fun????
