    Follow along as I make a replica of the Original Old Boy. I'm going to try to replicate this as close as possible.
    I had a Burny SG body lying around so that didn't have to be made. The neck on the other hand will be scratch built.

    The neck is the first thing I started on.

    Here we go!

    Scratch Built Neck

    I made this neck blank several years ago for a LP shaped body I had lying around but I never got to it. So I decided to add a 2” piece of mahogany to the heel end and use for an SG body I have as this will become a replica of Tony Iommi’s worn Old Boy.
    The fingerboard will be a 24 fret and it will have the Zero Nut and the neck will join the body at the 22nd fret.

    After all the measurements were laid out the Truss Rod slot was routed out.
    The T/R being used is a Hot Rod from Stew-Mac.

    The headstock and neck taper templates were made of ¾” MDF.

    The neck tenon was made and cut the same way that Gibson does it.
    The tenon is machined at a 3-degree angle using a Drill Press, Machinist Protractor
    And a flush cutting routing bit.
    The neck is placed in a vise and the Protractor is set at 3 degrees. I than angle the neck back until the bubble is centered and lock the neck into place.

    Neck profile and headstock shape are routed out.

    Neck Profile being shaped.

    A replacement SG neck from Gibson is used as a Guide for shaping.

    I love the neck profile on my 61 RI SG so I got this idea on how I can duplicate it.
    I will use a 2-part Casting Resin to make sanding blocks.

    After wrapping a piece of plastic around the neck of the 61 RI, I built a clay damn around the area I wanted to copy.

    [​IMG]
    [​IMG]

    Pam Cooking spray was sprayed inside the area to act as a release agent.

    Than I mixed up 16 oz’s, 8 oz’s of both Part A & B and poured it into the clay enclosure.

    After 20 minutes the liquid hardened into a solid plastic chunk.

    [​IMG]
    [​IMG]

    Than I cut the block apart to use as a sanding caul.
    It worked perfectly.

    [​IMG]

    Being this neck tenon was a bit smaller than the pocket that was already cut into the body I had to shim each side approx. .020 “ with a Mahogany Veneer.

    Fine tuning the fit if the heel to the body.

    All that’s left to do now is inlay the fingerboard and I can glue it to the neck.
    I won’t glue the neck to the body until I have it fretted, bound and the tuner holes drilled.

    Looking good Lou. Are you going to make the cutaways a bit more pointy (as early 60s SGs)? Always think most SG replicas (Japanese/Far Eastern - and a lot of new Gibsons!) look too blunt. :-\

    Yup, It will be done. If you look closely, you'll notice the pots/switch layout is slightly different angle wise than Gibsons.

    Re: Tony Iommi's Old Boy Replica construction has begun !

    I talked to John Diggins a few weeks ago, and I just had to ask if he had ever offered to refinish the Old Boy. He told me "yes, several times", and the answer has always been "No way, never!"

    Then he told me that it needed a refret recently and Tony let him do that, and when Tony approved of the work when done, John said "whew!".

    The name Tony Iommi obviously still carrys a lot of weight with John, even after all these years. I'm sure TI is still responsible for a lot of his sales, as well as John Carlings.

    Lou, yer Killin' me here, LOL. You have a new Old Boy coming, now you're building a replica. Let us know when you start on your own John Birch :-)
