As I said earlier this was started back at Christmas time, so there is a bit of progress to show.
Next came the part I was dreading most. The neck pocket.
Watched some YouTube clips for some inspiration and went to work. Made a template in MDF by clamping some straight boards right either side of the neck, and another inbetween them at the end of the neck and using that as the initial template.
Routed that out of the MDF, and that have a pretty good fit.
Access the template into the body (screws into the soon to be pickup cavities) and routed away with the pattern bit.
Couldn't get the full depth with the template on, so had to take it off and use the initial rout as the template.
Not quite as tight a joint as I'd like, but not bad for my first effort.
