Looking into building, have a few questions.

[BenitoBassolini]

So I've been cought by the bug of eubs... and I decided it would be fun to build one. I like the look of the NS eubs and drew a rough sketch of what I want to do.

Now, the problem is I need a good resource for the dimensions such as scale length, board length, nut, bridge width/spacing, etc. The other thing is I need to find a place to buy a truss rod that would work in a bass like this.

Any information such as websites about building, parts resources, and measurements would be greatly appreciated!

If you want to emulate the playing techniques of an upright bass, you and your tape measure need to spend some time with one, measuring lengths & angles.
A key issue I played with was the angle the neck joins the body (unless they're the same piece of wood), and this comes down to the bridge you use - if you plan to use a traditional bridge, you need a significant break angle to get the height. If you go with a flatter angle, you use a lower bridge and you can anchor the strings direct to the body rather than using a tailpiece (see www.fittell.id.au/eub ).
For a truss rod, I bought a couple of carbon fibre rods, 12mm x 3mm, and set them on edge in saw cuts under the fingerboard. However in retrospect, I think they were totally redundant as the neck is a big solid lump of hardwood that's not likely to move, and the fingerboard also has substantial stability.
Bob Gollihur's site has a comprehensive listing of EUB makers and basses.

BenitoBassolini - I'm maybe a week or two in front of you on the learning curve. What I've discovered is that everybody has their own take on EUBs, just as there are a lot of takes on DBs. I've found good information on other custom builds at:
http://gregutter.com/EUB-1.htm
http://liutaiomottola.com/instruments/libellula.htm
http://www.cyrguitars.com/ElectricUp...ojectPage.html

And of course reading the specs from the OEMs who build them.

Lastly, I'll second what ToneRanger said about Bob Gollihur's site. Eventually I know I'll be ordering some stuff from Bob.
