After making the holes large enough I needed to hammer in the ferrules. I got a piece of towel and put it over the headstock so the hammer wouldn't scratch anything. I then hammered the ferule in.
A little piece of blue thread got in the way though, and is now stuck on the headstock. The ferrule won't shift, so I guess it's now a part of the bass.
I then lined up the machineheads using a ruler, and I used a little pin to mark the areas I needed to drill. I widened the hole with a knife so the drill pit would work there properly.
The drill bit I used was very small. It was so small that I had to wrap tape around it for the drill to grip it.
Once the holes were drilled I put the machine heads on and screwed them in.
I'm happy with them. Nice and beefy.
Here's a lovely picture of the bass before I moved onto the next stage.
I was about to start sanding a roundover, but I knew the sander to be very loud, so I went looking for the earmuff which I knew were in dads chainsaw box.
Do you see the little steel box in the lower left hand corner of that picture? That's the chainsaw box
I wanted have a slight roundover at the top of the bass, but I didn't want to have a huge chunk out of the guitar, as I like it's slab design.
So I got my orbital sander and made a slight angle over the area so it was more comfortable, but still retained more if it's slab look.
I wanted to be really careful with the sander because my sister got half the skin on her face taken of by a hand held belt sander. They really shouldn't have trigger locks on them.
The next thing I had to do was drill a hole for the ground wire, so I started taking off the bridge.
I have never liked the normal screws that come with a bridge. I always think that they won't support it.
So I get these big wood screws that go deep into the body, that way I know that the bridge is not going to be moving anywhere.
I have a feeling that the bridge has just been painted black sadly, it seems to be coming off on the bass.
You can also see the little notch in the wood. I could of flipped it over and hidden it, but I liked it.
So I started to drill the hole for the ground wire, using some measurements to line it up with two drill holes. But I messed up the measurements, and in my frustration this happened.
That's the other side of the bass. Whoops.
I also took a bit of wood from around the cavity off by accident as well. I really shouldn't use drills.
Most of it is hidden by the pickguard, but a little bit is visible. It's pretty shallow, so it shouldn't be too hard to fix.
I also burnt a little bit of the wood and the drill in my frustration. Whoops.
Well you live and learn.
For now there is just some tape covering the hole in the back, but it will be fixed.
I now had to solder the ground wire onto the rest of the electronics. I didn't get pictures of it, but I did get a picture of my soldering iron holder.

I don't smoke, but I found it amusing.
After coming back inside and restringing the bass, I found the cat were it was when I started. On the bed. Asleep.
I'll record some sound files soon. If anyone want to ask questions/see more pics, just let me know.
So. What does everyone think of my day project?
