    Guys/Girls......

    Curious as to how much fret board material one will lose from a re-radius 9.5 neck down to a 7.25. Wanna make sure I'm not going to run the risk of sanding down to the position markers......My gut tell me I'll hit the markers, but figured I'd shoot out a quick thread to see if anybody knows of the top of their head how much material one can expect to loose. Thanks!
     
  2. Depends on dimensions of the current neck and where the position markers are. No one size fits all answer.

    Youre right, I guess width plays a factor. Lemme get some width measurents.

    Exactly why do you want to re-radius your neck?
    To answer your question, you will loos a minimum of .55" off of the edge of the fretboard. This is assuming its a 4 string Fender neck with a 2.5" heel.

    Here is a diagram I drew out

    Re-radius due to preference. However, .55 is quite a bit. Prob need to shop around for a new neck properly radiused from the get go. Thx.

    0.055 is a little less than 1/16".

    Thx for all the help guys....I'll check over the neck and see if it'll work. If not, a new neck might be in the cards.

    Easy typo to make. Worried the OP might have been scared off by the loss of 1/2". Hell I was scared by a 1/2" loss.

    There wouldn't be any fingerboard left after radiusing :D

    4 string or 5?
    Neck Taper width at nut and width at last fret...bridge.
    How thick is the fretboard?

    I wouldn't do it. What kind of a neck is it? You may end up sanding through the outer parts of the dots on the 12th fret, or blocks all across the neck. You will sand through the fret slots on the edges and properly slotting depth would likely go into the maple...Depending on how accurately that is done you may start hitting your truss-rod...and you are destabilizing the neck...a lot. If you remove material its like having 22 pieces of fretboard glued to your neck that are not connected.

    I think you will have plenty of room to take the radius down to 7.25" Just from measuring my instruments there should be plenty of room. You should double check before you start just to make sure.

    1/2 is quite a bit indeed!!!!

    But even 50 thousandths is quite a bit in the grand scheme of things [when dot markers come into play). Seriously reconsidering a new neck being built.
