Why do we use base 10 when we only have 8 fingers

Last year I built a bass that I have come to use it exclusively.
This year I am going to build a twin to it.

What they will both have in common
1 piece Black Limba Body.
1 piece Ziricote neck
African Blackwood Finger board
Gotoh 201 Bridge
Hip Shot Ultra lites
Bone Nut

Difference
Old build has EMG Geezers in it

New built will have a Nordy MM4.4, Might go to a MM4.3 instead
New build will have preamp that I got from fellow TBer Domdec314

Here it is mid-way thru routing off the edges

Here it is routed, planed, and rough sanded

As with the rounded edges, and wet for effect

I'm off to make the neck
 
I often wonder if I need to downsize the pics that I post. The camera in my new mobile device takes great pics, but at the price of higher download times.

Some one let me know if they are too large
 
Got a little more done today

Built up the base to my fingerboard radius jig
Also, finally got around to gluing down the FB.

Prolly wont get much done on this till next weekend

Cheers

Thanks for the comps on the wood. Nice thing is there is more where that came from.

Unfortunately when I took the clamps off the neck today, there was a gap between the fingerboard and the neck. It's about 2 inches long from the nut towards the heal. It's like this equally on both sides. I don't quite understand how this happened. When I clamped it down I made sure the glue oozed out. I used denatured alcohol to wipe the oils off.

I sure it can be fixed, but buggers, I'm not in the mood to do this right now.

I do have other options....... make a whole new neck out of
1) Flame maple?
2) Wenge?
3) Black Limba?

Decisions decisions.
 
If the new neck would also get a blackwood board, imo limba might look damn cool.
Might be heavy, though...

I looked up all the woods mentioned in wood database. Ziricote is by far the heaviest. Black Limba is the lightest.

I do have another Blackwood finger board. I'll probably go with the Black limba.

Made some progress, but not directly on my bass. I made myself a router rail.
I built it out of the cheapest aluminum stock I could find. I have a 1" L bracket gorilla glued and screwed to a .75" square piece of stock.
About 50 bux in raw materials and shipping.
The black piece of wood sticking out the far end of the rail is a wedge that I use to lock the rail in place

I have a couple other ideas I'll be using the rail on. More of that in the future

Currently it's sitting on top of neck jig that I built out of 6/4 cherry I had laying around.

I have it set to do 10" radius
My first test took me about 15 minutes to get it to a "full fingerboard" radiused, using a 1/2" bit. I think I may try a 1/4" bit to get it a little finer, but the time will go up.
For my first test, I'm pretty happy cuz I just eliminated ALOT fingerboard sanding. Now all I have to do is some light to moderate sanding

It rained all day yesterday and I had to go to my workshop and build stuff. This is what I was able to focus on.
1) Fixed the Ziricote neck.
2) Dialed in Radius Jig
3) Put a radius on the Blackwood Fingerboard (Ziricote neck)
4) Put a radius on the Ebony fingerboard Fingerboard (Black Limba neck)
5) Assembled the Bloodwood neck

As a whole, I'm pretty happy with the way the radius jig works. It's still got a little glitch in that I get about a 0.010 to 015 rise from the nut for about 4 inches towards the heal in the fingerboard. The rest is very straight and uniform. For the Ebony fingerboard neck it took me about 15 minutes to sand it down.

The bloodwood neck is an experiment that I'm doing on a whim. Never seen anything like this before. Hoping it will be stable enough. It is quartersawn. The wood itself has a very brilliant color to it. I currently don't have a body for it yet, but I have some Ash laying around that I think this would look good with


Thanks for looking!!!
