Super-lightweight P bass build

Finished sanding the fretboard and wiped a coat of oil on it. Just need to cut the slots a bit deeper then I can get some frets in.

I got the side dots glued in today.

Here's a question for anyone who's still listening. After radiusing the fretboard, obviously the slots are not deep enough at the edges where it gets thinner. Do you guys cut them deep enough at the edges and have them over depth in the middle? Previously I've just used a hand saw to deepen the edges so that the slot is more of a curve, but I could just put it back on the slotting saw and cut them all straight.

Yes, I saw them over depth in the middle and have a for a long time. I think ideally if you have a curved slot that matches your board curvature, then you are getting a little more thickness of your fretboard under the fret which improves the strength a bit, but no idea on how critical that is (or not). There may be more engineering reasons to have the slot match the curve of which I'm not aware. :)
 
I think I'd be more comfortable if I had a router with the larger 1/2" shank. But my janky little router table uses a Craftsman router with a 1/4" collet and it doesn't seem to be removable to insert a 1/2" collet. It just kinda freaks me out every time I use a tall router bit with a 1/4" shank.
I’ve got a couple of 1/4” Craftsman routers from the 1970s (made by Ryobi, I think) and they’re good machines but you definitely have to respect their limitations.

Given their limited power and 1/4” chuck, I consider them to be about equal to modern trim routers in capacity. Little bites with little bits is the way to go. For big bits and/or big cuts I use a 1/2” chuck because, like you, I get nervous using big cutters with small shafts.

The nice thing about those old Craftsman routers is that they occupy a nice space between modern trim routers and bigger 1/2” routers; heavier and more stable than a trim router and not as torquey as a bigger machine. For smaller cuts, as long as the wide base isn’t a problem, they’re pretty comfortable to use. …and you can find them all day long for $10 at yard sales.

I use Stew-Mac’s fret slot saw which has the depth stop on it so my fret slots are of uniform depth around the radius of the board.

You certainly don’t need that tool, though; you can cut a strip of plexi to sit on the side of the blade of your slotting saw and attach it with spring clamps.

A dull couple of half-hours checking, endeepening, and cleaning the fret slots and it's now ready for fretting, although it will have to wait until I go back to work next week.
The depth guide on the saw kind of worked, but I put it on the wrong side so it was blocking my view, and also I should've sanded it smooth and rounded it over, as it started leaving marks on the fretboard. So I pulled it off and just did them by eye checking as I went.

To be honest,a simple line scribed on the saw to show the cutting depth would be fine.
