    I am confused.

    If you look at the original Maton brochure for this style of guitar:

    http://matonmuseum.com.au/data/pdfs/...rbyrd%2070.pdf

    It talks about a "Double Thrust" truss rod (very '60's marketing right there). Does this mean you adjusted it from both ends, and that it was designed to distort (bow) in length?

    Also, what is the bit sticking out at the back of the truss rod drawing?

    Hey Paul,

    Just a thought, and a not fully thought through one at that, but are you going to do a solid colour on the headstock?

    If so could you do a fibreglass/resin layer as a reinforcement to get you the extra thickness you need? A couple of mm should be doable and "hide-able".

    Hi Rabbitz,
    I think they called it a double thrust truss rod as it seems to bend in two places. For some reason they have drawn it on an acoustic neck with a big heal.
    I probably will be using solid colours on it the body blank is a three part basswood blank. So if I do that I may as well put a piece of laminated Maple on the headstock.

    Cheers PK

    Where does one source basswood from?

    I've been looking but no luck.

    Hi Rabbitz,

    I got this bit from 'Guitar Makers Emporium' in Maleny Qld. it was on ebay reduced to $60 so I bought it. He did say he had some Mahogany but it was $115 and 2-3 glues pieces. I've built some stylised Wedgtails out of mahogany, and they weigh an absolute ton.
    The idea of using Basswood is to reduce weight.

    http://www.ebay.com.au/itm/Guitar-Bo...item3ab2e60421

    I've had a minor win on getting a headstock template, I leached a jpg copy of a tech drawing off the Net, and have shrunk it on the copier to get the right size.

    Cheers PK

    From building my accoustics I know I have to put a veneer on the headstock otherwise the tuner plartes would stick out above the surface of the standard sized neck...this is also to create additional strength in the headstock.

    Tks Gav, I've bought some maple headstock veneers, so I'll see how they turn up.
    Meanwhile today I started on the Templete.
    First I created a paper tracing, now I have traced that onto a sheet of patchwork plastic. this stuff is about .75mm thick and comes in an A3 sheet size, so it takes two sheets to make a the first level tracing. I do this as it creates a nice solid template to work from. Much better than trying to draw around a piece of paper.
    Next I will make an MDF template of the body shape. I usually make up three. 1, overall body shape, 2. with the pick ups and neck slots, 3. is the rear route.
    These guitars have a monster control cavity as they need to join up the 3 pos switch to the pickups and controls.

    Somthing very intersting with this shape is most of the curves fit nicely to my French curve.

    The French curve has a lot to answer for in many 60s designs

    I like where this is going PK, keep up the good work.

    There is always a workaround for glitches, mistakes and other Guitar building gremlins.....
