I drilled the neck holes by cutting some small stubs of sharpened welding rod to fit in the screw holes with only a small point sticking out (be sure it sticks out far enough you can get a grip to remove it though). I then held it tightly in the neck pocket and pushed down to put some nice accurate dents in the wood. I drilled them through with a tiny bit, then bought a 14mm forstner bit, and drilled down to the right depth for the flush neck washers. Drilled the holes out to the screw diameter and mounted the neck.
The pocket wasn't quite deep enough, and there were some imperfections where I had rocked the router and cut slightly deeper than the rest of the face. I used a forstner bit to drill it down flat, all except for the exposed edge, and some tiny chunks that I couldn't get at along the edges. A couple minutes with a sharp knife and a good file to trim the parts I couldn't do with the drillbit, and I had a very flat surface. The neck fits really well now.
The next job was to mount the bridges. Hipshot triple lockdown bridges are too expensive, and kind of a pain to mount. I really don't believe in stringing a bass through body, and wasn't at all impressed with the kink the string would have to go through if I did want to. On the next one I'll either build my own bridge, or buy the cheap ebay knock-offs. They're about 1/4 the price and just mount with 2 screws instead of bolting through the body and requiring a bunch of extra routing.
I marked out the holes, and then went to drill them only to realize that my drill press wasn't big enough to reach the D or G positions. I bought a ryobi 12" varialble speed drillpress (to replace my old 8" 5 speed with a broken top and bottom gear) It was a huge piece of crap which was way too noisy, had knobs that break off very easily and had way too much runout. I made the standard mistake of being too eager to keep working on the bass, rather than waiting until I could return it and buy something better. I drilled the holes, and then noticed that they were actually very crooked. :( (No pics here. I was a little pissed off at the time and didn't feel like taking any)
I took it back, and for only a few bucks more I bought a much better 14" press. It's got less features, but is better built and actially drills straight. It's 12 speed instead of constantly variable, and it doesn't have lasers, but it's better in pretty much every way.
So, at this point I had some badly drilled holes. Fortunately they were only about 1/2 of the final size. I figured that trying to drill an overlapping accurate hole with a standard twist drill wouldn't work (the bit would just follow the old/incorrect hole.
I took a piece of aluminum bar and drilled some small pilot holes at the right distances. I then attached it to the bass with some 2 sided tape, and drilled it out 1 size at a time until they were all the right size. It worked. They all ended up nice and accurate.
I didn't like the idea of trying to route all those little oval holes for the bottom of the stupid bridges, and since the bolts hold them in place anyways, I just drilled 3 overlapping holes with a forstner bit, just big enough that the bridges would fit in place.
Next I sanded the body. I did a pretty bad job of the sanding. It's alright, but I should have spent more time on it and gotten it perfect.
I used a large forstner bit and cut a recess behind the bridge bolts. I figured I could reuse the allignment plate on the back. I'll both act as a washer, and as a common ground location for all the strings if I choose to ground them. I also cut another template and did a 1/8 inch deep cutout for the cavity cover. Sorry no pics of me doing that. My camera batteries were dead.
