Hi, great forum here, I actually found it as I was researching this project.
I got a good price on this neck recently, I was told that it's a ~1967-71-ish Jazzmaster neck (it's a 25.5" scale). Most of the neck stamp is gone, all you can make out is "MAR", no date/model codes. It looks to have had the headstock cut down from the larger CBS shape. Someone had removed the original fretboard and put on a slab rosewood board, which was poorly done and cracked. I'm assuming that it had a "curved" rosewood board, and someone crudely planed it flat (possibly belt sanded?), and put the slab board on. I was actually hesitant to take this project on, but I absolutely love the feel of the neck, it's a B width nut, with a big fat C shape like I've always wanted. It also had the original Fender "F" tuners in good shape so I'm going to try to resurrect it with a 12" radius, rosewood fretboard.
Following the "fretboard removal" tutorial here, I steamed the old rosewood off. It was on with hide glue, so it came off in probably 20 minutes. Under the fretboard the planing was noticably uneven, and you could see glue spots in the shape of the old block inlays. I removed the binding, it was cracked, and had been planed into. Some of the side inlays were planed or sanded in half, and some were untouched. Since it's never going to be a collector piece, I removed the binding, and plugged the holes for the side inlays with dowels.
I've planed it flat (neck was over 1" thick at 12th fret with the 1/4" rosewood, so I did have a little room to spare, all I did was true it, removing as little as possible), and I'm looking at fretboards. I want to get one that's already radiused and slotted, I don't have the tools or knowledge to slot one. Also this project is big enough for me as it is, previously all I've done is stuff like bolting necks/bodies together, replacing pickups, simple refinishing). But I've done enough non-guitar related woodworking that I'm comfortable in gluing a fretboard on and having it be true, and shaping it. I'll likely have it fretted somewhere though, I'm not ready for that.
Anyway, here's where I could use some input: I know that neck binding is typically done over the edge of the fretboard, but what I'm considering is getting some plain maple binding, gluing it on, then planing it flat with the surface of the fretboard and putting the fretboard over the top. #1 I don't want to lose any width, #2 I just think it's probably the easiest way to do something like this for the first time. I don't have a router, so I'm not comfortable trying to get a perfect fit with the fretboard to the inner edge of the route for the binding. It would be neat, but it's beyond my skill level, and honestly I don't have the funds to pay for it to be done right now (in the process of starting a business). Plus I just like doing stuff myself.
Any tips or advice? The route for the binding is now a pretty uniform .040" wide by .140" tall, if it makes any difference. It's pretty small, which is why I'm leaning towards just filling it.
I guess my main decision is if I want to:
1. get maple binding, fill in binding route, true it to top and edges and put fretboard over top.
2. white synthetic binding like original. I'm not sure the white would look right with the fretboard on top (it didn't really look right when I started, white binding, then big rosewood slab on top), and think the maple would be less noticable, but obviously it's going to be pretty visible either way.
3. maybe a rosewood binding, with a thinner rosewood board on top to blend it all together better, but I don't want to lose any of that fat C shape. Or maybe a 9.5" radius would keep the overall thick feel, while tapering the fretboard edges to the rosewood binding, without making it look like a big 1/2" slab, which is my concern with using a rosewood binding. I don't want to plane any deeper because of the truss rod, the wood covering it is pretty thin towards the nut and heel ends (maybe all the way, I don't know, I can only see the ends).
Thanks for any help.
