I'm new to CBN and on my first cbg build. I'm trying to build a 3 string cbg using a scarf joint with poplar 1x2 stock. I originally was going to have a longer headstock but do to trial and error with scarfing, I'm down to about 2 7/8" left of headstock. Ooops! The scarf angle is not much I think about 12 degrees. I am not sure how to thin the headstock down to fit the tuners. Should this be a tapered cut? Should the cut come off the back or the front? Where does the cut stop relative to the neck? How much distance needs to be between the first tuner and the nut? Here's a pic of what I'm working with. Any help and suggestions is greatly appreciated! Thanks.
Thanks very much Wayfinder. This is a big help.
Hi Dee Ann, like most of us, you are learning things the hard way, normally, the easiest way to thin the head is , just sand the top till it is ok, but , that is now going to alter your nut position due to your lack of length, so now you have to do it with a bit more involved, in your case i would remove from the bottom , as taking off the top will be more exposed to sight, just use a rasp to rough it out and smooth it with s/paper, at 5/8" you don't need to remove a lot for tuner fitting, you could also go to a single slotted headstock which you can do without the need to thin at all, whichever way you go, with that headstock length you will probably need to have 2 tuners 1 side and 1 the other as you need around 1 3/8" between tuners otherwise it gets a bit crowded for your fingers, so i'd probably go 3/4 from the top, then 1 3/8 or a bit less to the next tuner, and the one opposite in between those 2, you don't have a lot of fiddle room there.The 12 degrees will be fine, but i'd try to move those tuners as far forward as i can without making it look silly to get a good string angle to the first tuner post. i've added a couple of pics to give you some ideas.--- http://www.cigarboxnation.com/photo/decked-out-1?context=user
Thanks Darryl. Very good info. Love your pics. I'd like to try a slotted headstock on the next build. Too late for this build since I used a pin in the scarf joint to keep it from slipping when I clamped. I added 1/4" wings to the headstock to give myself a little more space to work with. Can't say its going to look pretty, but it will get the job done. I measured the tuner placement for 2 on one side and one on the other and it will work out well. Thanks again for your help.
Thank you Wayfinder. I love the visuals. You've definitely given me some things to think about and more decisions to make. I forgot to mention that I'm planning on using a fretboard! This will certainly add to the string break angle. Turns out the 5/8" thickness is ideal for the tuners I'm using. I was planning on using a bolt for the nut, but maybe I should cut the holes and see what the string height looks like before deciding on bolt or zero fret? Thanks again for your help.
If you are using a fretboard, then simply cut off the top face of the headstock with a handsaw and sand it flat,to about 1/2" overall thickness. It will move your nut position back a bit, and will expose the glue joint on the headstock, but you can cover that with a piece of veneer for the cosmetic appearance if you want.
This also give the advantage of leaving a slightly longer headstock with more space to arrange your machineheads. One thing to watch out is that the position of the nut will be shifted back , so you'll either need to move your bridge position back correspondingly, or make the scale length slightly shorter.
Either way, all you need is a handsaw, sandpaper and a sanding block.
Thank you Chickenbone John. I am such a visual person. Thanks for the drawings!! Love your idea. I think I could get away with the shorter head, but it looks so funky with the bigger Ashton box I'm using. I've got plenty of neck length to work with. I'm going to try your idea of cutting down the top to create a longer head and more angle for the string action. Thanks so much for your input.
My mistake Dee Ann, from your original post i thought you were running out of neck length, that is the only reason i suggested thinning the bottom, if you have plenty of wood , certainly thin the top, it helps everything, break angle h/stock length etc
No worries Darryl. I ended up going with Chickenbone John's suggestion of shaving off a little from the top, creating a longer headstock. It worked out well. I'm finally over that little road block and am on my way to the next step. I had added little wings, but now that the head is longer, the wings are...well...short. LOL. A vicious cycle! I'm moving on! I built a jig for fretting and that is a real game changer!! Plus, it was fun to build...anything to be involved with woodworking and being creative. Thanks for your replyl
I enjoyed this topic, it was a good refresher for me and I liked Chickenbone's idea. This shows me why next time I do a scarf joint to do that very first thing, sure will relieve the scale length headaches behind.
I have some Cherry veneer, but it really is very thin veneer. If I had a joiner, I might consider the thicker stuff. What kind of joiner do you have? I might need one. (Haha) Hubby bought me a combo belt/disc sander, but I'm not good with it yet and have created additional problems for myself. :) I have lots of machine tools to work with, but I'm enjoying the hand tools. Thanks for your reply.
