Two 4 string basses: 34" Maple-Ash-Buckeye burl "Traditional" model, 32" Wenge-Padauk "Mio" model

Hi there!
I'm a newbie in this forum, I'm an amateur bass builder based in Italy, I build 2-3 instrument per year, I started making Carl Thompson copies, but now I'm trying to find my own style.
I hope to learn a lot here, receive precious advices and share what I know.
Thanks

  • The first is for a Canadian guy, he want something that look like an Elrick, I proposed my model "Traditional" (like this), he want also a pair of Bartolini that will sounds good with slap technic, so I choose the new Singularity pickups: a single-coil jazz pickup in a soapbar shape. The Buckeye Burl top will be filled with photoluminescet epoxy, and i will place an Italian flag somewhere, because my customer is proud of his italian origins.
 
Spec:
 
Handmade custom bass model "Traditional" with tonal chamber and sound hole
34" scale
24 medium jumbo fret (21 on E and A string)
3 pieces Maple neck
Buckeye burl headstock with Ebony TR cover
Single action Stew-Mac truss rod
Indian Rosewood fretboard with Paua Abalone square "Gibson-style" inlay
Fretboard radius 12"
Ebony nut
Thin neck width 38mm thickness 19,5mm at nut
Set neck (glued in the body)
Ash body chamberd with Buckeye burl top and Maple back
Top filled with photoluminescent epoxy
Varnished with Danish oil
2 Bartolini Singularity pickups single coil in a soapbar shape
1 EMG BTS preamp (bass-treble) 18V with Active/Passive switch
Hipshot A style bridge black
Black strap lock
Strings DR Lo-rider nickel-plated medium

  • The second is for a Swedish guy, initially he ask me to build a Claypool replica, but with different wood: Wenge, Padauk and Rosewood. I propose to him one of mine model (I called it "Mio" that means "My" in italian) and he accepted. This model shape is a mix between a CT Claypool and  Ritter Roya, and with the body stripes, the tremolo bridge and this control panel it's very close to the Claypool bass mood. The customer immediately had very clear ideas about this bass, he want an EMG 35DC at the neck, a Bas-Mid-Tre preamp, a bolt-on Wenge-Padauk thin neck (I suggest a Ritter style multi-screws bolt), an inlay at 12° fret, no battery box in the back. He use to play in BEAD, so I choose a Kahler 2400f with forward saddle, in order to have more space to use D'Addario XL  long scale strings, because it's not easy to find low-B strings for 32" scale bass, and also the headstock is 1cm forward; I choose  .135/.100/.075/.055 strings gauges in order to have a light and balanced set.

In this mockups you can see my old "thompsonish" logo, but I will not use it anymore, I'm working on a new logo, as well as I'm working on my building style

This is the Buckeye burl  for the top:
attachFull2452639
 
My customer want to fill the burl with photoluminescent epoxy (it's my first time with epoxy...:
attachFull2452640
 
And I will try ro recreate the color of the Paua Abalone inlay, I will try with different pigment colors.

Some stuff

This is the wood for the second, the body:

The neck:

Fretboard and control panel:
attachFull2452645
 
This is the Kahler 2400f tremolo bridge, a beautiful piece of engineering:
attachFull2452646
 
I'm checking if the long strings scale will fit in this bass, they do!

About woodworking:
I cutted 3 pieces from a flat European Maple blank, in order to have a 3 pcs quartersawn neck
attachFull2452649
 
With an hand plane I planed one surface
attachFull2452650
 
Than I planed the other side with my neck-blank-router-jig, in order to have an angle on the blank itself
attachFull2452651
 
Here you can see the angle
attachFull2452652
 
I did the same with the Wenge-Padauk neck

Welcome. The mockups look great - they are going to be fantastic basses.

If you need any tips on using epoxy to fill your burl top there are some great ones on ProjectGuitar.com. Some of the builders on there have used mildly radioactive compounds to great effect, which sounds similar to what you are planning

Thank you all for the kind words of welcome!!

Slowly I'm working...
 
Today I glued the skunk stripes

Here you can see how I  work on the skunk stripe in order to let it fit the truss rod

The TR is glued with epoxy, skunk stripe with Titebond

I also start working an the MOP custom inlay for the "Mio": I glue the MOP on Rosewwod, I cut a circle with a hole saw and I filled with epoxy and Rosewood dust.

If you can produce builds close to your mockups... and you haven't hit any other snags or issues like resonance etc ..
I'd say you aren't an amateur..or will stay one for very long.

The proof is in the finished product of course, but I'd think you'd have to have...or may well have, serious furniture making skills.

Good luck

The plans look great, and so far things seem very promising. Keep at it, and if you can post loads of pics and details (or as much as you want to).
As you know, measure twice, then check everything again - then cut - and you should be grand. Wood if funny stuff so there's never a guarantee it'll work as
well as hoped - but given the progress so far I am confident you'll have a pair of very elegant musical tools at the end of all your hard work.

Thanks for sharing! :hi:

@JTUK I hope my builds will look better than mockups! Ahahah
Seriously I think to get enough close, but as I’m not building replicas I have some freedom...
I started to build instruments 5 years ago, I built 7 basses and 2 guitars, and all this instruments currently works
But honestly I didn't have any furniture making skills, and I'm still not able to make forniture! A friend ( an ex violin maker) taught me how to use hand planer, chisels, scraper and how to sand the wood (he also gave me the [/size][/font]carpenter's table and some chisels!) and a guitar maker taught me how to do fretjob. I learned all the other things watching Carl Thompson videos on YouTube (I spent entire nights watching..) and in various forums.
 

I did all the fretboard inlays, I was at the first attempt with inlays, the block was not so difficult, instead the custom inlay was a real PITA! and radiusing deleted a part of it attachFull2477019 so I had to replace the missing parts...

attachFull2477023
 
 
 
attachFull2477024
 
This Paua Abalone is really awesome! After this pic a glued the blocks with Epoxy and Rosewood dust, then I glued Ebony bindings on the fretboard and then I glued it on the neck.

attachFull2477030

attachFull2477032
 
attachFull2477033
 
This is how it looks like before radiusing... it was almost perfect!...
 
attachFull2477034
 
And here how I restored it:
 
attachFull2477035
 
This is the extension to allow the use of long scale strings in this medium scale bass. Now I need to remove some Padouk binding, because for my customer it's too thick, I will route away the side of the neck and apply a Wenge binding under the Padouk

And here both the necks with the fretboard on:

I have not posted updates here for many months. Both basses are finished.
 
I will show you some pics of the building, first the "Traditional".
 
This is the Ash body glued and routed, front and back
attachFull2533350
attachFull2533351
 
I glued a black veneer on the back and added the magnets for the back control plate
attachFull2533352
 
Here how I cut the back control plate from the Maple
attachFull2533353
 
Making space for the magnets
attachFull2533354
attachFull2533355
 
I glued the back Maple wing using the back control plate to find the exact position
attachFull2533356
 
Ready to route the extra long neck pocket

The bass with the neck on (not glued)
attachFull2533358
 
and the back too.
attachFull2533359
 
The back control plate is pretty good
attachFull2533360
 
As you can see I had to enlarge the holes for the magnets to find the exact alignment, it's not so beauty, but I will cover with copper foil.
