    Tony Iommi's SG Build

    Well I have gotten far enough along with this that I can finally post for all to see.

    Templates for neck profile, body, headstock shape and the raw materials.
    I had already inlayed the dots in the fingerboard when I took this "group shot.

    Logs to Lumber supplied the ¼ sawn 3 3/4” x 3 3/4” x 36” neck billet
    eBay My World - logstolumber0

    North Ridge Hardwoods supplied the 14” x 19” x 1 ½” body blank
    Luthier Tonewood Supplier, Guitar Tops, Body Blanks, Acoustic Sets, Neck Blanks


    [​IMG]

    Lets start with the Fingerboard.
    It's an ebony pre slotted Gibson scale from Stew-Mac
    Found the center of the board, intersected a center line at each position marker and drilled them out

    [​IMG]
    [​IMG]

    A drop of Crazy Glue into each hole and in went the 1/4" pearloid dots

    [​IMG]

    Drawing the Neck outline of the template

    [​IMG]

    Marking the 22nd fret ( where neck will join the body ) and the end of the fingerboard so I can mill off the "Drop off" area just past the end of the FB

    [​IMG]
    [​IMG]

    Milling the 3 degree angle into the tenon

    [​IMG]
    [​IMG]

    Flip the neck over and mill the -3 degree angle onto the bottom of the tenon.

    [​IMG]
    [​IMG]

    Here you can see the angle in the neck tenon with the "drop off" and the bottom of the tenon parallel with each other.

    Body blank rough cut on the bandsaw.
    I busted my last 1/4" blade so I had to use a 3/8" blade instead. What a BITCH to cut tight curves with it !

    [​IMG]

    Body template that was accurately Cad drawn off of a early 60's SG Jr.
    THANKS MAGNUS !
    ( Note the reminder : THIS SIDE UP LEFT HAND )
    I had to write that on all of the templates so I don't mess up ! LOL

    [​IMG]

    Routed to shape with a 1/2" bearing guided template bit.

    [​IMG]

    Holes drilled

    [​IMG]

    Control cavity's excess was drilled out with a Forstner Bit and routed to final shape and depth. Cover lip was routed out along wuth the cover it's self.

    Stew-Mac Hot Rod Truss Rod slot cut and T/R set into place

    [​IMG]
    [​IMG]

    FB profile cut - 1 11/16th" at the nut and 2 1/4" at the end.
    using this jig I made. It's set exactly 4 1/2" between the blade and the fence. Line up my marks at both ends with the edge of the board and the angle is cut.

    [​IMG]
    [​IMG]

    Don't "Fret"...Just do it ! LOL
    I also run the wire through my home made fret wire radii thingamajig !

    [​IMG]
    [​IMG]

    Smear a little Titebond into the slot, wipe excess with a damp cloth and hammer in the fret.

    So after 4 days this is where I'm at. I'll shape the back of the neck maybe tomorrow and i'll route the mortise into the body. If all looks good I'll glue up the neck and the bulk of the build is done !

    Yea, It's a great book. read it cover to cover in 3 days.
    I was at the NJ book signing that Tony did so I got it autograped as well.
    Thats where we sealed the deal for me to build him an SG

    [​IMG]



    I have no clue as to where to even begin making plans. :lol:


    Nope, He has plenty of SG's with cross inlays.
    I'm building him a replica of his 64 SG Special aka Monkey SG

    [​IMG]
    [​IMG]



    I don't think he really even knows I started the build...unless his tech. Mike already told him about it :hmm:


    Thank you all for the kind words Guys...........Coming from "Master Builders" like your selves it means a lot ! :applause:

    Had some time off so I worked on Tony’s SG a little more.



    I used a Laser Level to align the neck center to the center line of the body.

    [​IMG]

    Using Carpet tape I taped these laminate faced guides around the tenon of the neck.
    I also added a piece of vinyl tape to each side of the guide to make the size just a hair smaller then the actual tenon size.

    [​IMG]

    Then routed the tenon.

    [​IMG]

    Perfect fit !

    [​IMG]
    [​IMG]
    [​IMG]

    Now comes the “Acid test” - hanging by the neck with no glue in the joint ,
    SUCCESS !

    [​IMG]
    [​IMG]

    Marked the center line for the bridge right at 24.75”

    [​IMG]

    P-90 Sized cavities drilled and routed out.

    [​IMG]
    [​IMG]

    Aligning and drilling the wire channel….You can’t imagine how much I prayed the bit doesn’t wonder and come out the top or bottom of the body.

    [​IMG]

    Perfect !

    [​IMG]

    Bridge Stud anchors drilled and pressed in…but not before running the ground wire !

    [​IMG]

    Starting to look like an SG !

    [​IMG]

    That’s all that I had time for. Will probably contour the back of the neck and glue it up next week.

    We’re getting there, slow but sure !

    Grain filled and shot with 4 coats of Cherry dyed Sanding Sealer.
    I'll sand it and shoot the Cherry tinted Clear on this weekend.
    Hopefully if all goes well I should have it done by the end of this month !

    As of yesterday ( Tuesday ) the last 6 coats of clear have been sprayed.
    The body and back of the headstock are done. I'm still spraying the face of the headstock with a spray can of clear until I build it up enough so I can bury the decals !

    Won't be long now ! :applause:

    Well here it polished out after being "force cured" after 2 weeks.
    Force cured equates to hanging in a very warm room here at work !

    I think I'm going to let it continue curing for another 2 weeks and wet sand it again with 2000 grit paper then buff it out again !

    It's ALMOST finished.

    In between doing the LP headstock restoration I was able to:
    Wet sand and polish out the SG, wire it, fit the tuners and bridge.

    Still left to do: Cut the nut and final adjustments.

    Awesome!

    Thanks for posting. What an honor!

    It would seem weird building something like that & not being able to play it (because it's l/h) & setting it up for someone like Tony.

    What an unreal build! The video you posted of Iommi playing the end result is the Auckland gig that everyone here in New Zealand is raving about..

    God it must be a great feeling seeing something like that, your work in his hands.

    That is amazing o.O , I love SGs... even though I play bass (I think the SG basses look goofy compared to the guitar). Dang, that is absolutely beautiful though.
