Thanks for those pics.
Fretboard will be epoxied and I'll be drilling out the neck on this prototype. if it all works out, I'd likely machine some sort of chambering into the neck.
Another lunch hour spent cutting and grinding.
Re: A Few New Projects
22Just an fyi, and I'm sure you've already considered this but I'd be very very conservative w/ how much chambering you end up doing. Obviously neck-dive is a thing w/ these guitars but based on our mutual friend The Duke, you can see where they lose some of their ability to resist bowing if there's not enough material there to hold strength.c jury wrote: Thanks for those pics.

23the chambering in a TB:
The chambering drastically reduces the surface area for the fingerboard to bond to the neck. As as I understand it, in the later years of the original Bean run the necks were made thinner by about 1/8", then they sandwiched a solid strip of aluminum between the neck and fingerboard in order to have a greater surface area to glue to.
Garth -- have you seen the Gletty aluminum necks that have truss rods, over on instagram? Pretty cool:

Re: A Few New Projects
24Nope, sure haven't and it's interesting, but I thought one of the big selling points to an aluminum neck was never having to mess w/ a truss rod? Although I guess since the aluminum would not be subject to changes in humidity and temperature to the same degree as a wood neck, it'd be more of a "set it and forget it" situation?pastlives wrote: Fri Jan 14, 2022 2:39 pm Garth -- have you seen the Gletty aluminum necks that have truss rods, over on instagram?
Re: A Few New Projects
25Yeah, I chatted with Marc McElwee (the guy who designed all of the TB shapes minus the Wedge) about this a few years back. Travis's idea was that with an aluminum neck, it would be a 100% "set it and forget it." He saw that Marc was working on guitars and always fussing with the necks and thought, "Well, let's just make it out of metal to avoid all of these issues moving forward."Garth wrote: Fri Jan 14, 2022 3:35 pmNope, sure haven't and it's interesting, but I thought one of the big selling points to an aluminum neck was never having to mess w/ a truss rod?

Of course, there are the rare stories about Beans developing a bow over the years, but it seems pretty few and far between.
There's an entirely different school of thought re: guitar building where folks argue that the neck absolutely needs a truss rod (hence when Ian from Specimen never actually made an aluminum neck, just aluminum bodies over the years.) These Gletty ones seem to be bridging that gap, though I'm not 100% if it's a gap that needs a bridge.

Re: A Few New Projects
26Just so much to learn. Thanks everyone for everything you're posting. I'm aiming for just taking a central channel, maybe 1/2" wide, 1/4" deep at nut, maybe 3/4" x 3/8" at the base.
Today I drilled a line of holes down the middle of the neck. I also worked up the nerve to use a standard wood router and bit, used a chamfer to take the corners off the back of the neck. Weight in now down to 6lbs 4 oz. Settled on a bridge and pickup config. Will take all sort of pics this weekend.

Re: A Few New Projects
27Given that I was working remote all week, and had today more-or-less free, got a lot done.
-cut headstock to rough shape
-cut neck to rough shape
-ground angle into headstock (about 8 degrees, similar to a ric)
Drilled a center channel into the neck to relieve weight

28Built a fixture to hold the unit, machined depth from the front body portion and the distal taper of the neck

Re: A Few New Projects
30Holy cannoli, that's just a bog-standard router? I would've never thought those would be suitable for using on metal...are you having to use special bits? or is aluminum soft enough to mill w/ normal box-store wood bits?
Also, the work area doesn't look wet, but any metal cutting I ever did in a factory had coolant or oil applied...although that was all steel-cutting. Huh. Learnin' shit - thanks for sharing!
