Mike that's looking good! How will you cut out the neck, so that the body end is precision flat?

I will do that with a router and the neck template, since both sides are square to the fretboard face.
I rough cut both necks from the blank today with a bandsaw. Looks like I can get a Uke or Mando neck out of the left over piece.

Looking good Mike! Would you be able to take pics of the routing process? What size/type of router bit are you using for this?
The fretboards (1 slotted and 1 fretless), truss rods, CF rods, MOP dots are due in from LMI tomorrow.
I bought a used Squier for $70 to use for a pickup experiment.
I am going to throw together a test body to try out an under bridge "mystery pickup like the original Ampegs had before I route a pocket for it on the scroll basses.
I recieved the .018 spring steel and garolite bar stock from McMaster Carr today for the mystery pickup.
This is what the original Ampegs had under the bridge. (Thanks to TB member Rockelye)

Here is the second set of tops and backs was just resawn today from a 3/4 x 8" maple board that I bought on ebay.
I went over to a friend's house and borrowed some time on his mongo thickness sander and thickness sanded both center pieces and all four tops and backs.
Have you ever seen a jointer, a table saw or a router?
How is it frightening? You put wood in and stand back. The wood slowly comes out the other side. There are no saw blades or jointer knives spinning...
You put the wood in one side and it comes out the other side sanded.
The feed rollers that put downward pressure on the belt won't let the wood go in unless the height is within operating range
The belt that the wood rides on it fed at a constant rate by a second motor and the belt feed is height adjusted at all four corners by a chain drive adjustment.
Because of the chain drive feed belt and the upper rollers that you can not see the wood can not be sucked in or spit out by the sanding drum.
If the sanding drum is adjusted too low it just stops.
There is a spring loaded bar on the feed side with a switch under it and if you push the bar above the wood the machine shuts down and stops very quickly.
This machine is safer than a 4" belt sander.
Safety rules are pretty much the same as all shop machines.
Do not lean over the machine wearing a tie and do not stick your hands into a machine while it is running.
Thos machine works great and is accurate to .005" to .008"
You want a frightening shop tool, check out my table saw (held together by corroded 2x4s).

Yes, I've worked with all of the above but in a "DIY repair" capacity, not in a serious shop situation. I'm aware of tool safety, and I'm sure that you wouldn't do anything unsafe. I haven't been in that kind of a wood shop since high-school and that was a long time ago. Sometimes though you forget what the real serious tools of the trade look like.
I have been looking around for a "not too expensive" pickup to use for the under bridge pickup. It needs to be less than 3/4" tall and 1/2" or 5/8" would fit in the cavity better. I posted a question in the pickups and electronics section of TB yesterday but no responses so far.

I know a couple of guys that wind pickups and if I don't find a pickup that will fit in there pretty soon I will make some bobbins and send them out to be wound.
The "neck" (bass or middle?) pickup I was planning on some kind of soap bar pickup. I have a couple of the Mosrite P-90 looking bass pickups I might use... depends on funds at that point. I am sinking more money into these 2 scroll basses than I planned on but oh well... I'm having fun...
I started making a quick pine and birch plywood body to test the setup of the under bridge pickup. I am going to use the neck and most of the parts off of a Squier P-bass that I picked up for $70 on this body to test the mystery diaphram pickup. On this step I will also make the template for the material to be removed from the sides (or wings) of the body.
It is just bandsawed out in this pic.

Everything is starting to come together
I have the two maple center pieces and all four the tops and backs joined and thickness sanded to 120 grit.
I recieved the LMI order last week with the fretboards (one fretless fingerboard and one fretted) and the truss rods, CF rods, dots, fretwire and some other stuff.
Also I stopped by Industrial Metal Supply last week and picked up some aluminum bar stock for the tail block, bridge and saddles.
Today I recieved the stuff from Stewmac, Schaller tuners, nut slotting files for bass and a few other tools... I try to buy a few tools with each order.

if they are the eastwood 90's supposedly they are pretty good. they are single coil keep in mind. the original AMB (2nd type) had a humbucker.
I made some more progress on the test build to test the under bridge pickup. The center is pine and the top and back are birch plywood.
This is the "test build" the actual project will be all maple.
(it is not glued to the back in this pic)
