Still not sanding.
When you start modifying guitars like this it's not just the gross problems like the stud position that catch you out it's also things like the shape of the tremolo route.
In the first photo you can see that the treble side of the bridge lines up perfectly with the edge but the bass side has loads of space. This isn't because I've put the bridge in the wrong place but because the bridge isn't symmetrical down the centre line of the guitar and the route is.
The route needs extending further 'south' so the baseplate doesn't hit the body and then deepening so I get more upward range on the tremolo.
My only attempt to do this kind of thing by eye with the RR2V went badly until I started to use a template and move it around. Clearing up the mess left me with a weird 'bathtub' route.
For the RS10V I want to try and keep it tidy and looking more like something a conventional guitar would have, but I have only got an asymmetric router template that is exactly the right shape and size for a Floyd Rose Original.
Flipping the template over, then moving it back slightly and doing so again looked like it would give me just what I need. Having tried this out on paper and done some measurements it checks out OK.
I've got a huge sheet of clear acrylic thick enough to make a new template using this method but I think I'm just going to cut it out of some old wood instead as I can't see me using this template more than once.
