I had the pretty much the same issue when I built my first iceman and it ended up being a little similar to the raise which is evident on the treble side of the neck a few photos up. what raised my fretboard was the treble side inner corner sort of tapered in like / to the bottom of the corner. So when bolted it felt well seated and secure but was held off the bottom a couple of mm.
A little bit of material removal from the bottom to bring the sidewall straight and the bottom of the corner and the neck sat nicely down. May not be the same issue but worth a look.
Thanks mate. I'll rip the neck off and get some deeper gauges in there to figure out what's going on. Just when you thought you'd had a productive weekend, cleared the guitar, wet sand, polish, assembly in 2 days and your about to plug her in. Ahhhh the fun of it all. Wouldn't have it any other way.
Fixed! I did a thing! I'm the most unhandy person and I fixed it with beer, swearing, a screw driver and a file. Before you ask, no you can't seen the pocket now haha. Strung her up, first impressions. The 3 way needs to do a 180 and the 2nd fret buzzes so I'll sort them out next day off. Now I can break out my new fret files and fret board protectors!
Andrew good result and sometimes its just the tools you use to get the job done. Looking forward to seeing the finished product.
Beer is an underated building tool, makes an excellant sanding aid, can cool a brow when things start getting difficult and great northern bottles wrapped with sandpaper are exceptionally good for shaping headstocks and body cutouts.
