Under the neck plates of pre-CBS Strats

Discussion in 'Pre-CBS Strats (before 1966)' started by dueducs, Mar 20, 2017.

  1. Hi All,
    I recall seeing this pattern on several pre-CBS Strats under the neck plate (image stolen from @Tyger). Can someone tell me how or why this pattern is formed? Is this a common pattern formation or just an anomaly?

    If I had to venture a guess, I would say that is where the screws caused the most pressure.
    Or oxidation from the screws themselves. Not sure if those were stainless back then.

    Yep, the plate is pulled harder against the wood at the four screw points, causing this diamond effect.

    Particularly noticeable when the lacquer has not fully hardened (which is generally the case when these are first assembled)

    I tend to agree with this theory, sounds reasonable and makes lot of sense.
     
  7. So, by this hypothesis (which does seem feasible), we should also see more modern guitars finished in nitro have the same pattern. Do we see that?

    I also wonder, due to the uniformity of the pattern if torque wrenches were being used for the neck screws. Thoughts???

    Popeye must have tightened the neck plate on the used Tele I bought, the corners of the plate are inside the body.

    If you see the plate distorting and the screwdriver bending you should have stopped a half a turn or more ago.

    Yeah when you start to strip the grooves on the Philips head screws, I think it's time to stop turning it.:D

    Just imagine how deep they would drive them if the screw head slots did not strip first!

    I don't think you'd want to measure the force needed on the neck screws in foot pounds.

    More likely to use a torque screwdriver that measures inch pounds.

    And even if you'd control the force, you'd still have the phenomenon of the screws on the corners of the rectangle pulling more, so the plate would still deform and you'd see the diamond pattern.

    Every piece of wood is different, so torquing to a spec would be inconsistent at best. Sometimes it would be too much, other not enough.

    My !995 MIA Standard has a very similar pattern. however, It is poly, (exceptionally thick poly) The process was different, but the outcome can still be seen.
    Thanks BTW, I needed motivation to change her strings and clean her up a bit.

    I've always thought it was from the grease they used on the screws.
