Another guitar kit build

Postby blinddrew » Sat Apr 04, 2020 3:50 pm

I won't bore you all with the full build diary on here, but I thought I'd just share some of the key stages along the way.
So here's the initial take-it-all-out-and-check-it's-all-there-and-fits bit.

The pictures on the website show a very slab sided body, so part of my plan was to cut away at the shoulder and to make a belly cut.
However, on opening the box it seems the kit has been upgraded slightly.
Shoulder cut (I think I'll go a bit heavier on this though):
Image

Belly cut (I shall probably roll over the edges):
Image

Fitting it for a mock build shows lots of play in the pocket so some shimming* will be required here:
Image

Lining things up looks pretty good, neck pocket shimming notwithstanding.
Image

Typically, instead of thinking 'yay, less cutting and shaping' I have instead had an idea about how I could make it more complicated.


* It also occurs to me that I have no idea how long the scale should be and therefore whether any additional shimming or cutting will be required at the end of the neck pocket.

I suspect you already know this but for the benefit of anybody who finds this later, the scale length (nominal) will be twice the distance from the nut to 12th fret. The bridge saddles will be slightly further away to correct the intonation.

Looking very nice Drew will follow with interest. :thumbup:

Yep, I will measure and make sure I'm making sensible allowances for intonation etc, it just occured to me that, unlike with guitars, I have no idea of what a standard scale length is.
Google tells me 34" though, :)

34" is pretty typical.

Apparently Leo F stood up, stretched his left hand out and measured the furthest he could comfortably reach and arrived at 34" for the original electric bass scale length.

As good a way as any i suppose. :)
Though I probably would have started by looking at an upright and taking a couple of measurements there...

Yeah, but you'd struggle to get in under your chin then ;)

That explanation may be apocryphal TBH. Bear in mind Leo was not a player but had, presumably, worked out that you couldn't hold an upright sideways and still reach the top of the neck. I guess he knew he needed the longest scale that could be played like a guitar.

So it does. :)
The fun is going to be figuring out a wiring diagram, but that's one for the other site. :D

And twist the two non-sheath wires together?

Thanks Wonks. :thumbup:

Yes, the two coil linking wires per pickup (as they are humbuckers in the kit, rather than the single coils shown in the diagram. Though soldering and then some heat-shrink over the join would be a lot safer.

Or you could wire them in parallel rather than series, but you can always do that later. Or get a couple of DPDT on-on-on mini switches and have each pickup selectable for series, parallel and coil split operation.

Keep the unsheathed portion as short as possible and you won't need to.
I typically untwist a length of the sheathing and turn it into a pigtail, then fold it back and slip a short length of heatshrink over it, covering the point where it leaves the outer casing. Cut the core to about 10mm from this point and strip about 5mm off that for making the joint. The folded back sleeve tail can then be soldered to the top of the pot (although my preference is to take it direct to the adjacent tag on the pot).

Ah. Now you've confused me (easy to do I know). Exactly what wiring is coming from the pickups?

That looks really nice, Drew. A few questions come to mind:

    - The website says £136 - what is the total with postage and import duty?
    - I wonder what sort of value it will have when complete (compared to purchasing an equivalent quality bass)? Perhaps not easy to answer, but interesting.
    - Is it a good idea to shield the cavities, or unnecessary?
    - What sort of finish will you go for?
    - Won’t it keep falling off the wall when you put it into its guitar hanger?
