A different take on the Weissenborn neck joint

[Bob Connor]

I built a Weissenborn last month that ended up with a twist in the neck. One side of the nut was about 1/4 of an inch higher.

So I thought I'd strengthen up the neck joint from what I had been previously been doing.

The original joints were as shown below, with spruce stiffeners in the neck.

I decided to extend the stiffenners and incorporate them into the headstock to give it a bit more strength.

It seems to have worked. The last two weissys have been flat as a tack. I'm not really sure why the other one warped. Probably a cranky piece of timber that wanted to move but I thought I'd share what I consider to be an improvement in the original design.

I don't know anything about Weissenborns but your new solution makes perfect sense to me. Stronger, more stable and it seems to me that it's even easier to install and align.

I used cf bars in the last one I made (similar in principle to the flying buttress braces I use in my guitars):



I use this system in hollow arm harp guitars too:

This is funny timing Bob, I was talking to a young engineering student on Friday who was into building Weezy's & he wanted to have a look around my 'shop', he bought his rather nice teardrop shaped Weezy with him (it was the first Weezy I've seen 'in the flesh' & I was impressed, it was a beautiful all Sapele job), but I looked at that joint & enquired how it got it's strength. Now you post & show me!
Like Markus I can see the merit in your system over the original, funny how the original twisted though, as you say the wood must have been a little hinky for it to want to twist because from what I've seen, that's quite a 'boxy' area up in there.
