I will leave the neck alone.
Hmm. I work in a tool shop so getting the tools is not an issue. I could use the larger router trimmer base that Makita make. I think that may just work. The more I think about it, the more I realize that it's not a huge task really. It's just scary thinking about what could go wrong LOL.
I was probably going to take the neck off again anyway to set it up.
All good
