Hello again! And next little project, a travel bass of sorts

Post by Jarno Verhoeven »

Hello all,

I was here 19 years ago, when I started a project which was way too ambitious, and obviously, that did not go anywhere (a 6-string fretless headless semiacoustic like the Leduc Ubass). In the years that followed, I did a few assemblies (A jazzbass and precision), and a few basses of my own design (shortscale 5 strings, same shape, but one in neckthrough with two soapbar pickups, and one bolt-on with a musicman stingray pickup).
Recently, I've been intrigued by the Maurizio Miezo basses, but I did wonder about usability. And then we had some discussions on the dutch bassists forum about the Mayones Cali, which I liked but also had some comments on, so I thought, "why not built my own?".
I am more into building furniture these days, and I actually bought mahogany to make a dovetailed (houndstooth dovetails) whisky cabinet. But I did wonder where to put it when it was done, and the wife found the mahogany too "old-people-esque", so I figured to use it in a bass instead :D

I am still using the same 3d mechanical CAD program I was 20 years ago, so I did a little modeling and figuring outing:

So here is where I am right now:
20231107_172639.jpg
A 5-string travel bass, tuned E-A-D-G-C (as my other 5-strings), but an octave higher, through neck, 530mm scale length.

Will also be my first bass I will fret myself, earlier I've asked other people to do this, but I really should put on my big boy pants now :)

That's going to be a nice bass, 530mm sounds ultra short. Only comment is - would smaller locking nut heads be better with a travel bass?

Thanks! Yeah, it is short for a bass, but note that it is tuned an octave higher, so E-string tuned to the same pitch as a guitar (still about 4" shorter scale, but still).
Good comment about the locking tuners, hadn't thought about that, need to think about it a bit, it's still wood so detuning will also be caused by temperature and humidity changes. Probably need to tune it always (but a built in tuner would be nice, do they still make the ones fitted to the end of the fingerboard?).

A headless bridge would give you the ability to travel without the knocks or environmental change changing the intonation or tuning but you loose space unless you loop back the strings on the underside but that's a whole world of issues.

My first inspiration were the Maurizio Miezo basses, and those are indeed headless. But even though there's a headless bridge design I did ages ago in the old library here on MIMF, I didn't feel like going through all that trouble, and I also am not going to fork out 250+ euros for an ABM bridge so regular tuners it is.
Made some progress too, there was a tip on the dutch woodworking forum on a little bandsaw for 50 euros, it was located on the other end of our (admittedly tiny) country, but luckily I have family in the region. Took receipt of it last saturday, fully expecting it to need major work (given the low cost) but it is actually in very good condition. The blade tensioner was assembled wrong, so that was easily corrected, but it runs great, plows through 100mm of ebony and 130mm of maple with no problems.
20231111_211702.jpg
So I cut the scarf joint on the bandsaw, rough cut the headstock to thickness, cleaned it up and glued it.
20231112_152026.jpg
I bought two types of blade, one wide 16mm 4tpi blade, and a narrower 10mm 10tpi blade, so I fitted the fine toothed one and cutout the body wings. I've never used a narrow blade like that on a bandsaw, but it works really well with cutting the curved pieces.

Had a chunk of ebony laying around, so I cut the fingerboard from that, and the maple I bought was birdseye maple, so I cut a back and headstock veneer, and planed all of those.

Made a fret slotting jig and fret slots sawn. My stewmac saw was a bit blunt, so I used my Dozuki for most of each slot, and cleaned it up with the dedicated fret saw.
I only had a depth stop on the StewMac saw, so I still ended up with a few slots really deep on one end, hopefully they don't crack, will fit frets only after glueing it to the neck.
Hopefully route trussrod channel later today.

Refined body wings, routed trussrod channel, planed top for neck angle, drilled holes for positioning dowels, rear contour sawn, headstock broadened slightly (really only needed 5mm each side).

Had some sidetracking because of secret santa woodworking, and an old tablesaw I bought which needed some work (and turned out to need EVEN MORE work, so I put that one to the side, might even need to have the motor rewound.....).
But day off yesterday, so visited a lumber yard for veneer and furniture wood, and bought some Madrone burl veneer, because I felt that the birdseye maple headstock veneer was a bit on the light side compared to body and fretboard.

20231220_080232.jpg
Added veneer to front and back of headstock, glued yesterday, was still pretty containing quite a bit of humidity this morning, hopefully that clears up today.

Also, used regular woodglue, will need to see how well that works, those burl veneers can be a bit finicky.

Veneer is on pretty good, no gaps or bumps.
20231220_204726.jpg
Did a lot today, glued on bodywings, routed headstock outline, pickup cavity.
Two of the tuning machine holes feel closer to the edge than I'd like.
Did some rough shaping of the rear of the neck. Still debating whether or not to fit a bookmatched back.

Managed to pretty badly mess things up to day, luckily without getting hurt. Palm routed grabbed, and slipped out of my hands.....
Leaving a few marks :(

Spent a major part of the day repairing

It's looking great!

Sorry to see the marks from the slip up, but from what I can see, you've got this.

Did some work on this bassulele this weekend, routed battery box and control cavity, radiused the fretboard, put the front dots in, started sanding.
Currently pondering finishing options, and whether or not to apply grain filler. Was thinking of using the Rustins Plastic Coating finish, and first do some grain filling, but given that it has a maple back and laminates, I would need to do two colours of grain fillers and associated masking. Also, I do have some tearout on the birdseye maple, so some filling required.
The other option would be to do a bunch of layers of nitro from a rattle can and be done with it, decisions decisions. I have the rustins on my neck through DIY build, but I didn't do that myself, looks really nice, but that is a process.....
Will add some pictures in a minute (they are on my phone).

Added a hole in the neck block to connect the battery cavity with the control cavity and a groove to connect the pickup cavity with the control cavity.
Works really well, was afraid of it getting drenched in glue, but not too bad actually.

Also, used dowels to position the wings on the neck block.
To place them, I needed to plane the neck angle on the top of the neck block, and I decided to plane the bottom as well, don't do that, leave it proud and plane it flush with the wings instead. I went to far and had to glue in veneer to fill the gap to make sure I could glue the back on.

Hey Jarno,

I'm psyched about your project, as I was/am in the same boat.
I'm building a bass for myself, since I could find a bass I liked (too heavy) at what I'm willing to pay (under $2k).

Please continue to post pics! I'm sure it'll be great!

Thanks Matthew, yeah, keen on stringing this up and trying it out. Judging from the fret slots, it'll require fine motor skills to play it :D
I taped of the maple parts and have put on mahogany tinted grain filler earlier today, do some sanding tomorrow and maybe put on a first coat of nitro.

Thought about Rustins Plastic Coating, but that is too much of a process, especially since it smells really bad, and I have to do it indoors because of the temperature outside right now.
Also order some strings, honestly should have put a bit more thought into that upfront, but there we are :)
Ordered the 5-string set for an Ibanez Mikro 5-string bass, and I'll tune that E1 to C2, I think that'll get me in the ballpark (low-end) of string tension. The commercially available ones are tuned from E2, that's also still an option, with a regular 4 string set and a high C.

Did grain filling, but hated the fine dust all over the maple, so did fine sanding and the first layers of nitro.
Looks good not perfect, but there are oopsies in there anyway.... :D

Marginally better lighting, some tearout visible in both top and back, next one will be better (adds thickness sander to wishlist :) ).

Fitting the frets went well, drilling sidedots less so, another oopsie. I am using relatively large sidedots (3.2mm) and had a drillbit that wandered a little bit. Next time, I'll drill those holes after tapering of the fretboard, and before glueing it on.
20240121_170347.jpg
Wrt fretting and fret finishing. My takeaway was that it makes sense to have a dedicated tool to clean fret slots, I hit the finished top with the regular saw, so that area needs a touch up.
Also, the adhesive of extra strength painters tape bites into the nitro finish, another area to touch up.
