Okay, so this isn't my first cigar box guitar, but I need some ideas for headstocks. I would like to make something simple but nice. It's a 3 string with Alaskan birch wood.
You need to be a member of Cigar Box Nation to add comments!
gorilla glue? gods above no! Gorilla glue is only good for furniture with sloppy joints... it expands as it dries. Any good wood glue, slightly contracts pulling the joint together. gorilla glue will push joints apart, misaligning them...

Thanks a lot, Sam! You have definitely upgraded my understanding of these things. So the" wings" will hold with appropriate glue. Like Gorilla glue? Or Elmer's Carpenter's? I'll definitely look up scarf joints; thanks again.

Well, yes, mostly, sorta..... If you're building a headstock design that is wider than the neck, you generally just glue "wings" onto the side, and then cut out the shape you what. Assuming you use good wood glue, between smooth surfaces, that is more than strong enough to hold up to the strain of tuners.
In necks that angle away from the plane of the top of the neck there are two options. First, start with a thicker than necessary neck stock, cut away from the bottom of the neck for the actual "neck' part and angle cut the head stock portion. But... mostly, people doing angled headstocks are making "scarf" joints. These are secured with glue joints. and if done right are plenty strong.
search "scarf joint" and you should get a lot of info including pics.....
hope this helps,

Probably a dumb question, but I'll ask it anyway: When the headstock is broader or thicker or slanted back from the neck, it has to be a separate piece of wood, right? And if so, it would have to have a truss rod or some such strengthening to prevent it from collapsing. Please correct me or clarify. Thank you.

Use a PVA glue (Titebond is very popular over there in the US - Evo-Stik here in the UK), and clamped properly, your joint will generally be stronger than the wood itself. (Try breaking one apart and you'll see).
I wouldn't use Gorilla Glue as the glue expands while setting. Ok, this will fill tiny gaps but is a weak joint as the expanded glue contains entrapped air bubbles.

The last one was actually done for me by ron marr, "Blind Doughboy" in SW Missouri.... it's a scarf jointed oak neck with "wings" of canary and blood wood that is then bandsaw'd into an abstract pattern.... Not that hard to do once you're comfortable with working scarf joints and bandsaws.
I still have one that he build for me on the shelf... If you need design help, let me know....
sit down with a piece of paper and just start schetching....
fretted, frettless, slide, picked, scarf neck, not, slotted, padddle, fender style modern art..... where would you like to start?
how are you equipped for tools?
There's a few thousand pics in the photo file that should give you some great ideas.... After that, we can give you some more ideas... You're also welcome to roam around my photobucket account... over 1000 pics, mostly CBGs...
