Extra thin neck on old bass

Discussion in 'Setup & Repair [DB]' started by Doug D, Apr 18, 2012.

  1. I've been asking a lot of questions lately about my latest project; an older flatback upright.

    this time its about the neck width at the nut.

    this one measures 37.5 mm give or take....and the reference material I have states that normal is around 42mm (which is only 5 or so mm different..... but this old bass seems A LOT thinner than standard).

    Has anyone heard of adding material to the side of the neck and carving it into the neck profile (I'm adding a new FB too which should help)

    Only other option would be to do a scroll graft?

    Where are you in the southeast?

    If you are already putting a new fingerboard on, you could flare the edges so that the profile is wider and sneak the 2.5 mm on each side.

    Are you measuring the neck width or the fingerboard width? Was the previous board shaped like james said, flaring outwards to a more standard width at the board surface? If so, it probably wasn't built like that, more likely someone "thinned" it from the sides. You could always start by adding 1/8" maple shim on top of the neck, to reinforce the neck and build it up a little, start the flare into the shim and continue into the ebony.
  4. measuring at the fingerboard width. the previous board has a small bit of flair and yes, definately was planning on including more on the new board but didn't want it to feel drastically different.

    I worked on an old Kay factory 5 string and it was basically a wide board on a standard 4 string neck. Felt like about a quarter inch overhang on each edge of the board. not exactly what I'm looking for.

    and I'm fairly sure this board/neck was reshaped because when siting down the edges, they curve in towards the nut.

    including a reference picture....
