Janus Bifrons (Bass commission) Finished!

Yeah, I take it out into the sunlight also.
I hate to sand...hate...hate ...hate .:spit:
 So I rarely will do it all at one sitting.
I typically will do all the easy stuff that can be done with my pneumatic orbital. Then take on one hard area at a time, like the heel to body transition, then do something else. Then all the inside radiums of the edge.Then do something else... then the endgrain at the tail...etc... Sometimes might use alcohol to wet...& find scratches. The 70% stuff has a bit of water so it will raise the grain a bit. Then sand some more. Yuck boo piss poo waaah... :thumbsdown:
So.....Are you saying that sanding isn't among your favorite things to do?....:confused:
 
I think he dislikes sanding, that's the impression I'm getting, so let's chat more about sanding. Any point in raising the grain more than once? I put a nice gouge in the raised part of the neck beam on mine when I wandered too close with my random orbit. More bondo and filthy curses. Now I'm hand-sander Boy.
 
So, I tried to draw up a program to mill a top load tailpiece with the "Tormach" CNC mill. But that proved to be too much for my limited computing skills.
The first time I made a top loader...I did it with an angle grinder, drill & die grinder. It came out ok...but was kinda pillowy and organic...which was ok for the rounded edge body it was going on...

But for THIS build...with its more precisely beveled thing going on...I wanted a bit more ...um...sharpness?
I have not used a manual (Bridgeport) end mill since high school....but that is what I used for most of this sucker. I think it came out ok :

Anyone familiar with the Hipshot D bridge...knows they use crummy little Philips head 4-40 screws for intonation adjustment. I like to replace them with socket head cap screws.
The front of my tailpiece is beveled to grant adjustment using a ball end allen wrench...coming in at an angle.

I am going to kidnap a crew of Oompa Loompas...or Keebler Elves .... maybe...Smurfs! Yeah Smurfs.
They will do all my future sanding!
Or they will feel the wrath of the Rockhewer!

Apparently, your version of "OK" is most people's "bass jewelry". That's effing gorgeous. If Bruce Wayne played bass, it would have that tailpiece.
Haha...thanks!
But I continue to refute the idea that it is Batman-esque....!! His sigil is completely different! :sour: really it is....isn't it?:cautious::meh:
Don't make me copy & paste the entire catalog of Batman logos for comparison...again....:woot:
Cause I will ....if I must :wacky:

Revisiting the idea of fabricating adjustable nutz.
Just for fun...


But then I regained my sanity.
Sorry... didn't like it....not one bit.
Too much like a bridge saddle on set-screw stilts.
Not good contact.

Thanks for the nice compliments guys...
Makes my day! :)

So, I have some stupid expensive eyeglasses from the optometrist....
They don't work.
A guy at my shop loaned me some Walgreens readers...hey I can see *** I am doing cutting this new nut!
;)

Just a clean...well cut nut...
No need for adjustability. (Dumb Alembic option)

I love the idea of an adjustable nut but can't for the life of me believe that they could transfer string vibrations to the neck nearly as good as non-adjustable nuts.

Love the tailpiece too. Lovely work.
Yes, I am sure you are correct.
And honestly...the more I think about the idea, I don't find it nessesary really.
If the nut slot depth is cut right, so that a setup can be performed properly... I'm not sure why you would even want to change it.
The option surely isn't worth giving up a nice solid contact point for...

And thank you for your kind words.
 
So...backing up a bit... I wanted to share a little point of procedure I used to set the body/neck angle that works really well.

Since this was to be an exposed neck top...
And because I didn't want the fingerboard sitting totally flat on the neck, where it meets the body....but only a very minimal gap under the very end.
(It makes it easier to get a clean transition when final sanding & finish is applied)
But neither did I want the, well over 1/16 gap it would take to grant proper elevation... and remain a "flat plane neck" to the bridge.

So .... prior to gluing the fb on, I routed the body area of the neck down a tiny bit....about 1/32"
You can kinda see the gap here:
20170407_201821.jpg

Not the best pic...
It starts back maybe 1/4" under the board.

BUT... I knew that would not be enough depth to have the bridge be in the correct adjustability range after the frets & strings were on.
Sure I drew it out before hand, but a secondary physical double check insures success.
So, after the frets were on....I could then lay a straight edge atop the frets and very accurately visualize exactly what I needed for proper bridge elevation.
And exactly how much body - neck angle I needed.
Creating that angle was easy.... on the boards I typically clamp on to keep the wings flush with the neck during glue up. I just glued a couple shims the appropriate thickness to the one I used at the lower bout area.

I made sure I left the neck blank at the body...thick enough to take the angle.
Then after the wing joints were cured up...
I sanded the neck flush to the wings with a belt sander. Being super careful not to gouge the cocobolo top & back in the process.
Taking this extra step (vs leaving it a "flat" plane instrument) and a couple other things done differently, had the result of this bass having killer action and playability.
So....There's that....:D:bassist:
Onward & upward....;):thumbsup:

Anybody else procrastinate doing their taxes until the last week possible?
Yup...so there's a couple days off work I didn't need...:banghead:

Got this one all sanded up nice & into the booth it goes for some of that sweet caustic catalyzed toxicity, that is: SW Conversion Varnish :rolleyes:....yummy!

Yes, one day soon... I shall invest in a decent gun ...so I don't have to work quite as hard sanding down all this orange peel.

The drop light reveals a sneak peek at the gloriously chatoyant edge figure I'm going to get for using quilted maple in the core...

Sanded out flat....awaiting a final coat:

I don't do anything after sanding to reveal the tiny scratches. What I do is just finish it, and then lament the fact that I didn't do anything after sanding to reveal the tiny scratches left by sanding and the gouges left by not sanding thoroughly.

It's only after you stop sneezing, and the muscles in your hands recover, that you finally reach the zenith of the Zen experience :p

Oh hell yes! Read my mind. :)
 
Pretty much done here...

Thank you all for looking... and the nice comments along the way.
This was a pretty special/important build for me for a couple of different reasons.

I ordered a flight case to ship this in...
It was from "Bestincase" cases.
I am doing a custom foam cutout & aphoulstry ...I will share pics when I get that done.
CHEERS! :)
