Doing Things Wrong

Radiatabacker Part I

This is the Ric body template I made earlier. What's the point of making a template if you only use it once? Underneath are the sections for the new body. I used about 13 feet of 2x2" lumber, under $20 at Home Depot. I arranged the pieces so the stripier faces show. I'm also extending the tongue on the template. I had a brain fart and cut it too short when I made it.

Now gluing the pieces together. I'm trying something a little different - I aligned all the back sides flush, so all the mismatches in thickness will be on the front. On previous builds, I collected all the differences on the back, this is easier. Ten pieces become four, then two, and then one. Then belt- and block-sand both sides flat and smooth and re-trace the outline. The blocks are arranged so that there are no small orphans at the top and bottom. This makes a much nicer edge if I leave the grain showing.

This will come out a little thicker than a real 4001, but the pine is lighter than maple, so it will be a wash on weight. You can also see the nice bridge I got at the lower-left, and one of the tuners. The string geometry will be 32", Fender spacing. Obviously, the neck will be a bolt-on. Finishing a separate neck and body is easy. Finishing almost four feet of neck-through is bigger than the facilities I have, unless I go with a lousy oil-rubbed finish like everyone in the talk_ass "build-offs". If I'm going to do something, I'm going to do it right.

And here is the final assembly, upside-down. It is clamped vertically to the workbench. I never did it this way before; it seems easier. The blank has a bit of cup on the back side, maybe 1/16", and a corresponding bulge on the front. On previous builds I flipped the pieces around to minimize that; I didn't bother on this build, I just trusted that the parts were pretty square and let the random universe take care of the rest. It will all sand out when I dress the faces. This can sit overnight.

I used about an inch of glue from that bottle. You really don't need a lot of glue, just a thin layer on both sides of the joint and then lots of clamps and a damp rag to clean up the squeeze-out. Don't over-tighten the clamps and squeeze all the glue out. They need to be just tight enough to close up the gaps. With just those four two-foot Harbor Freight clamps and a hand saw, you could do all this in your kitchen. What I really love about this is the beautiful result you get without resorting to over-priced "luthier grade" materials; just a couple of sticks from Home Depot. Search this site for "radiata" to see.


The skunk stripe is the walnut strip down the back of many 'classic' guitar necks. It is an indication of the type of truss rod within: A single steel bar in a curved channel. To create a perpendicular force, a truss rod needs two members: one in tension and one in compression. The skunk stripe rod uses the neck itself as the compression member. This was originated on a guitar neck and then extended to the bass. The problem is, a bass neck is much longer and less stiff than a guitar neck and is under much greater compression. The last thing you want to do is add more compression. Also, using two dissimilar materials for the two members inserts a host of issues, and using steel against wood, that's just hideous. The wonder of the skunk stripe is that most of the time you get away with it, despite how awful the design is. Of course, it is very cheap and easy to manufacture, in a factory setting.
