    That's going to be a fine looking guitar, Julie. I'm betting it will sound very nice, too.

    That's one thing that has me most curious. And, of course, how will it play? The fixed bridge really changes things compared to all the adjustability you have with an electric bridge.

    It has really come together nicely. Beautiful instrument. I have a sense of how much thought you put into wood tones and combinations (remembering the kitchen build!), and your choices here work very well together. By the way, nice color match on the bridge. Look forward to the next update.

    Looks nice overall.

    About voicing/bracing, my understanding (from talking to different luthiers) is that the top is shaved until the tone is gone and the top is "neutral."
    At this point, the top won't have a noticable tap tone of "bong" but more of an empty "thud" as alluded to on the Cumpiano book.
    After the bracing is done, braces are carved to the desired tone.

    After the box is closed, final shaping can be done by sanding the top (particularly around the rims).

    As for purfling, I don't think it affects tone as much as the voicing, top, liners, side thicknesses, etc.
    However, I'm an arm-chair guitar builder...

    Thank you, guys. I'm closing in on the finish but another project has taken precedent (orders from headquarters) so I'm not sure when I'll get back to the fine details of making the nut and setting the bridge.

    Not really having any experience with carving the heel of the neck, I sort of inched away at it and measured along the way.

    This is just awesome! I really like the look of it. I can't wait to hear how it sounds. (We WILL get recordings, right? )

    Only if I can record someone who knows how to actually play. 55 years after first picking up a guitar, I still only know three chords, the chords to Gloria... G-L-O-R-I-A. Oh wait! There's another cord I learned from my brother but I can't remember what it's called.

    Julie, you don't need to know a whole lot of "chords" to be able to enjoy the guitar. I'm a keyboard player, but have had some fun "just playing around" with my guitars. It's more of a feel thing as you get into it and you'll be surprised at what you start to hear.

    Hi,Julie. I haven't been here for months,so just now saw your guitar making thread. You have been doing some nice work. Very fine craftsmanship. However,I am concerned that the ends of several of the top's struts are not inlet under the liner . Many years ago,Gibson made some low end guitars that were like that. They were problematic because the un end tucked struts would come loose.

    I always tuck the ends of all my struts,and have also been cutting little pieces of linen (not cotton as it rots!) I saturate these pieces with glue and fit them over the X that the 2 longest top struts have. I also fit the linen where the short struts are tucked under the long X braces. I make longer strips of linen about 3/8" wide,and glue them at the edges of the bridge plate on both sides. Half way on the plate and half way on the top. I also glue the linen down the center line where the halves of the top are glued together. I do this because over the years I have seen several guitars where the top seam has opened.

    Does all this "insurance" hurt the tone? No. The last guitar I made and posted pictures here was a real "cannon". That's what they call loud violins.I can apply it to guitars too.

    Having reinforced the weak areas of the strut ends,I can be assured that they will not come loose and buzz,or cause other trouble. BTW,I was appointed a factory authorized Gibson repair man back in the 60's.
