Anyone ever make an 8 string CBG? Im wondering do i need to put a truss rod in due to the tension?
Also it will be acoustic with a sound hole so dont want to have a through neck CBG which Ive never done before. How do people fix the tail/saddle to the box to ensure the tension doesnt break the box?
I haven't done an 8-string so I won't comment on that, but I will offer advice on what I have done. That is, when trying a new build technique, work at it incrementally. Try what you want with a 3 string or format that you're comfortable with first then go after the final product when you have confidence in the design. You might think this will take longer - building 2 or 3 additional instruments before the 8-string, but it may still save you a ton of time, materials, efforts, etc.
Cheers Eric. I have made a lot of CBGs and different types too. The thing thats throwing me is not having the neck all the way through the body - I am worried about the tension. So I am wondering how others anchor their neck and strings to ensure this doesnt happen? (dont know if my original question made that clear)!
On this 6-string resonator I put blocking on the back to retain the strings. The tension is carried in part by the runners on the outside of the box. However, I did have to add extra reinforcement to keep the neck from twisting upward a little bit. I simply sunk some lags or wood screws into the mahogany cross from the edge of the box.
Super eric thanks. A lovely looking CBG.
What sort of pickup are you using there?
Any problem with the 6 strings and tension? perhaps I dont need a truss rod.
