My bad in that I didn't notice the fret board is already slotted.  I am with Bizman62, a little up-bow will probably be countered with the compression from installing the frets.  Your rods look pretty tight so I doubt them slipping is a problem. 

Two things, measurements of how much of an up-bow would be helpful.  If the carbon fiber rods are two stiff, the string may not pull the neck into enough bow for suficiant relief.  In that case of the bow is fairly small it may be a good thing.  The second is that in my experience, carbon fiber rods are installed with epoxy which holds it in place.  CA glue may have left them too loose to stop the bowing.

That is one nice looking build.  Are you going to set it up for heavy strings to counter the floppy low B on the short scale or is it going with a high C fifth string?

I agree with Drak.  That is a plywood guitar.  It still could be a decent instrument.  You have lost the thickness of one ply which may or may not be a problem.  To fix this you need to clean off all the existing glue on the bottom of the bridge as well as on the guitar.  You also have to remove all of the wood sticking to the bottom of the bridge.  Then place the bridge on the guitar and use a straight edge along the string path to see if you can still get decent string height.  You may have to replace the saddle with a taller one but if much more than half the saddle height is above the slot you can have problems. 

There should be a reinforcing bridge pad under the top.  Use a mirror to make sure it is in good shape.  If all checks out I would glue it up with Titebond or other good wood glue.  Normally I like hide glue but Titebond has better gap filling for this one.

That is stunning!

Very cool build idea.  I confess the idea of planing that makes me shudder at all the tearout I would get.

This is very cool.  I am Facebook friends with Adrian Below (only met him once)  I would like to share pics of the finished product with him with your permission. 

If you can't get a clamp in place, I have used magnets with good results.

Would love to see some pictures of that

I will post some.  Not much to see right now.

I am very slowly restoring a Pfishner (sp?) aluminum upright bass.  Unlike the Alcoa ones this one has a real wood neck, bracing, etc.  Your approach looks similler, perhaps more conservative, so it should work.

Nice work.  I don't thin you have to worry that you stole the first one.  A pro would charge a minimum of $300 to repair it and it still would show.  The value of the work you are doing exceeds the re-sale price on the instrument.  So I think you and the seller did well.

Cool!

Surgical tubing can be used to clamp irregular surfaces. 

Nicely done.  I am in the process of working on a Stanley No. 4.

She looks great.  I think you may have to get them a dog next.

Congratulations on the well deserved GOTM win.

Tell him true love is worth waiting for.

Looking good.  Is Wally watching the progress or does he prefer to not know?

Don't drink and work.  Done't work when tired.  Know the hazards you are working with before you start and have a plan to protect you from them.  

You are doing the right thing asking.  There is a ton of experience here.  I worked for 25 years as a safety officer on hazmat sites.  if you or anyone else wants help, just ask.

It is done all the time.  

I look forward to the build thread

Speaking about physics, a doctor's ex has told me that modern medicine owes a great deal to the unethical Nazi Germany live human testing.

Back when I dealt with such stuff, toxicology and other safety data would sometimes have a note that some of the information was derived from nazi experiments and was thus suspect.  Given the horrors they did no one is going to do the tests again to confirm.  This was way less than 0.1% of the time but if you looked stuff up frequently over twenty-five years you did see it.  

I think talking about Wally and his girlfriend is a better subject to stick to.

Basically wood absorbs or transmits vibrations according to its size, shape, density and internal cellular structure.  How these things interact in a single piece of wood can be complicated.  How they interact in the multiple pieces of wood used in a musical instrument is incredibly complex.  There have been dozens if not hundreds of attempts to study what physical properties make for the best instruments.  They have been largely inconclusive.  To date the experience of a good instrument builder tends to produce the best instruments.  their have been collaborations between scientists and instrument builders that have yielded interesting results.  One of the. most successful has been the pianos by the Italian company Faziolli.  

I agree those pickups look pretty unique.  You may be able to get them repaired (rewound).  That would be the least intrusive way to go.

From the photo it looks like you have a pretty thick body at the neck joint. so I would be inclined to remove any wood from there.  I would take some measurements, some long paper and mock it up.  Then you would know precisely what to do.
