Finished Pics! Single Cut 5-string Short Scale


Andyjr1515

Recommended Posts

And today was chamber day :)

KpXsT3Ml.jpg

Weight relief top left; shallow weight relief top horn due to cutaway the other side; battery slot in control chamber; access from the Superquad chamber to the control chamber for the SimS 140-wire (or that's what it feels like) wiring loom and connector; no weight relief at the lower horn because we are going to have a deep cutaway cutaway there (a particularly nice feature on @Matt P's design); no weight relief in the central area to maximise the stiffness and density between the neck and bridge (although, of course, there will be an enormous Superquad chamber in the middle.

This little lot...

...now weighs  around 7.3lbs, so, adding Superquad, pots, tuners but less wood still to be carved, I think we are on target for 7.5lbs maximum, with some remaining options up my sleeve if I'm wrong :)

Time to ponder and take and record measurements so I don't inadvertently carve into the chambers once they are hidden...but we're almost ready to get that top on! :)

While I'm still not decided whether there will be any further major carving at the back, it always pays to know where the hidden chambers are and how deep they are.  I simply take a paper template to keep in the file:

And write the respective depths of those chambers:

I also pre-drilled the bridge earth wire holes in the top and the matching one in the back - it's a lot easier (and less scary) than once it's fully assembled.

Then, after a final 'have I forgotten anything important' pause, the top is now gluing.  And no, you can't have too many clamps :D

Very soon and it really IS going to start looking like a bass :)

Yes it does, @Jakester , yes it does.  xD

 

And it's glued and it's trimmed and the cut out carve is started and it's dampened and the bridge isn't straight and there's a drop of water on the fretboard...

 

...but it IS starting to look like a bass :)

And i thought i was excited before!

 

the 24th fret access was definitely something i thought about at the start, it's partially based on my current 5 string and partially on my first guitar (an Aria Magna superstrat)  why have 24 frets if you can't get to all of them!

Oooh! Oooh! I will buy all the little Ukes!

I did a number of passes, ending up with a 4mm deep slot:

Then, from the other side, cut the chamber as I do my pickup chambers nowadays...starting with a Forstner to part-depth:

Then chiselled the periphery to act as a guide for the bearing on a top-bearing router bit:

DkFIkIDl.jpg

 

So now, and only now, when it is captive and can't go anywhere because of the bearing, out can come the horrible hand router... :

...to tidy up the sides and gradually deepen the body until breakthrough!  :

And, with a mm adjustment of my chisel line eventually release.  And we have a grain matching, 3mm thick back cover :party:

I think the phrase, 'Well, you could knock me down with a feather!' springs to mind.  I wasn't expecting that!!!

Time for a cup of tea, I reckon....:D

 

 

That's really clever! I have a bass that has a matched grain cover, and it had me beat how that was achieved, now I know ;)

The other way, if the builder is working off a thicker blank is to take a thin slice off - over a few mm, the grain pattern wouldn't be that different - and that would then mean that the gap could be quite a bit tighter than mine.  But it does mean having an industrial size and quality of band-saw.

With the Superquad on its way, it's time to start the back carve.  While there is a broad plan, this will 'morph' as the carve happens.  First, I carved the back of the lower cutout, extending the sweep of the heel cutaway.  Then I started scooping bulk out to take some more weight out and also provide a bit of 'too many biscuits' relief ;) . 

It won't be a @TheGreek 'contact lens' symmetry at the back - I am preserving the depth of the control chamber until I can be sure the SimS multi-wire loom will fit without the need for a screwed back plate - but that same vibe.  So out comes my beloved Veritas Pullshave :) :

JwFbvFAl.jpg

The pullshave is designed to scoop the shape of wooden chair seats...so after a hard gig, @Matt P will be able to flip the bass upside down on top a tripod and sit on it! :D

Because I have actual chambers and potential chambers and fixing screws to accommodate, I'm doing this a bit at a time, with plenty of pauses, measurements and ponderings.  This is where it's at so far:

That would probably already sort the effect of too many custard creams - but I'll be aiming for a full jaffa cake depth :)

When that's done, I'll then go back to the heel and reshape that.  And by the time that's done, the SuperQuad will be here and I can start thinking about the top carve :D

Softly, softly catchee monkey...

Creeping up on the back carve.  I've checked once again all of the carve vs chamber depths and am fairly certain I'm safe from any unexpected breakthoughs ;) 

Rough carve not quite finished but probably one more session will do it ready for scraping - and by then, the Superquad will be here and I can start on the top :) .  As I predicted, the carve has morphed and I've added some extra modest waist carves which I think will suit the look :

Another discussion @Matt P have had is the best position for the Super Quad.

I 'borrowed' this very useful photo off a Google Search (and many thanks to whoever originally posted it ;) )

The actual distances, of course, have no relevance, but the proportion of the saddle to mid point of the pickups to the full scale does, to an extent.  We've plumbed for the standard 'P' position which should sit in a decent vibration point pretty much all the way up the fret positions.  Happily, that's also pretty much bang on where Matt's 'it looks right here' original sketch had it :)

So it will be here:

And THAT means I could then forstner, chisel and rout out the chamber for the  pickup.  Note the additional rout for the connector block to sit:

And THAT means that tomorrow I can start the top and edges carve tomorrow and - if the day goes to plan - glue on the fretboard too :D

And to the carve.  Again, in the background there is a fair bit of backwards and forwards PM'ing between me and @Matt P as the carve creeps up towards final.  I don't know if other builders are the same, but the final carve contour emerges during the process.  I would say, 'the wood talks to you' except most folks would assume I'd been on the whacky baccy.

We'd got to this stage:

clYqo0el.jpg

But the walnut was singing like a siren at me.  MrsAndyjr1515 helpfully tied me to a mast and threw buckets of salt water over me, but it was no good (other than she, hurtfully, seemed to enjoy the process) - I had to leap into the stormy waves and answer the call. 

Well, what I actually had to do was PM Matt. :D

What about following the skewed oval... (top tip: school chalk should be handy at every builder's workbench)     :

dvL1qNjl.jpg

 

...and do this:

yyXsvJCl.jpg

Now, personally, I think that looks flippin' gorgeous :)

 

AND it means I won't get a reminder from @TheGreek to do exactly that because, almost certainly, he will have been ahead of me ;)   - he has an eye for such things and I hope that he takes some pride in the fact that I do, sometimes, take notice xD
