Slowly moving forward. After straightening the neck I realised I did have to shim the neck as all the other RC-4 builds have done when fitted the Rick bridge. It's a few mm higher than the bridge that comes with the kit and the action is way too high. I don't have any wood working tools as such, a few chisels, clamps etc, but found some hardwood axe wedges that I thought I could use. They were pretty much the size I was looking for and fitted in the neck pocket, it was just a bit thicker. I bought 2 just in case, made a bit of a jig out of some old wood so it would hold the wedge while I sanded, and after about 10 minutes had a wedge 1.2mm thick. Pretty amazed as was expecting it to be a bit harder than it was and fully expected to use them both. I decided to glue to wedge to the neck first and then if needed I can make some minor adjustments, and when it comes to setting the neck I'll only have one glue joint to worry about.
