Hi Gav,
I should also mention the depth is the rear of the existing route I had + what it needed to get to max depth, ie 4mm
this gave me a route depth of 18mm at the rear of the neck route, and 20mm at the front of the route.
I've done some fine filing and sanding on the route and it is pretty damn close to a perfect fit. just the tiny bit of force neded to push the neck home.
The front of the union is now quite flush with that little 1/4mm gap reduced to about.1mm almost thiner than the gap a secret fart can slip through.
Now working on a route template for some chrome mini Hums, the ones that were supposed to go on a Double cut. but didn't because the routes are too big.
On the subject of mini hums. I am thinking about a four pick up guitar along the lines of the one John Mayall is holding on the cover of Diary of a Band. Now that to me is a pretty cool Axe. #6 to the first one on this forum that build one..
#6 is rule Six in 4x4's and aptly applies almost any where
Rule #6 is every one gets a #6 or in easy terms a beer.
Cheers PK
