    Neck joint needs to be very tight and void free for best tone and jointing strength.
    I make sure the tenon is sitting tight in the mortise and that all surfaces are flat and gap free all around by carefully and slowly chiseling the area

    Neck should be snug even without gluing

    cutaway edges are marked for sanding

    and most of the excess material is sanded off

    [​IMG]



    Once everything is checked including fit and neck angle for bridge clearance the board is ready to be glued.
    I'll be using hide glue

    nut slot is wiped clean

    and necks are set aside overnight

    Reminds me a bit of this, which happens to be one of my favourite designs:

    One of my dream guitars as a kid.
    Designed in the 70's by Fujigen Gakki who also built guitars for Ibanez, Greco, Roland (GR-303) and others...
    I admit I had this in the back of my mind when deciding to go for both a double cut arched top and the round-over edges.
    Killer design except for the "so so" tone and boat anchor weight unfortunately... so I hope I'm doing some kind of justice by making the Lyra sound great (emphasizing "hope") (-;

    Knowing your experience in building first - class guitars, do you think that "so so' tone is due to bad wood choice or a pickup option?

    Usually wood. A great guitar with a bad PU sounds good, a bad guitar with the best PU still sounds bad

    Some guitars just ring without being plugged in. Good wood and solid joints do that. Beautiful work preeb.

    It is easier to tune the top before the neck is glued to the body but I need the neck for tuning.. so here's what I do

    tops are sanded
    [​IMG]


    I will use a thick scraper to thin the re-curve perimeter

    [​IMG]


    and deepen the recurve a little at a time

    [​IMG]


    before tapping I insert the neck to get a true tapping tone of the assembled instrument

    [​IMG]



    I try to do it little by little because it is very easy to miss the sweet spot and overdo this..
    Once I get a rich big bell tone I stop and measure the recurve all around to make sure it is more or less even

    [​IMG]

    [​IMG]



    If all is OK I rough sand the scraping marks and blend the new recurve surface to the top

    [​IMG]


    done

    [​IMG]




    The maple top build ended up with slightly deeper recurve for its sweet spot

    [​IMG]



    Both will get the neck glued once the necks are shaped and ready to be glued in a couple of days since I have to let the necks completely acclimate after the board hide gluing.
    If any of the necks warp due to the introducing of water (in the hide glue) they will be discarded and it is better to catch this before gluing the necks to the bodies... (-;


    [​IMG]




    Here are the final tap tones. Very good level and timbre for both but note the difference..

    Thank you.

    Yep.. but wood matching is above all.
    Most wood blanks sound ok and the main reason for failing to fulfill the full potential is the mismatch

    Not trying to tease.. it is still in development and testing.
    Waiting for Teoni to finish the winding so I can test them... it will take a while and I may not like it so I'd rather shut up about it for now until I get some satisfactory results from a very wild design idea I have in mind.

    Some last body drills left to be done.
    Template is used to mark the input jack and strap buttons locations

    [​IMG]

    [​IMG]

    [​IMG]


    With special attention to the top horn drill. It is always a pain to put a strap button on a non flat surface not to mention a pointy horn edge...
    I opted to install it against the bottom flat of the horn. It is nicely angled and sits flat.
    The large strap locking system I'm using will look nice this way too

    [​IMG]


    5/16" from the edge to have enough room for the button

    [​IMG]


    since the body is hollow in that area I will drill through the wall as shown

    [​IMG]


    done..

    [​IMG]



    rear strap button drill is centered

    [​IMG]



    input jack drill is done with a leveled drill

    48 after gluing the board the neck is checked for any movement or warping..

    [​IMG]

    [​IMG]

    [​IMG]



    Using a flat steel straight edge on the flat back of the neck is a great way to verify there is no warpage

    [​IMG]



    All is good! I will check it again after shaping the back of the neck and before gluing to the body tomorrow
