    Going over tomorrow to join the sides and install the blocks. That will be about all we get done. He is going out of town. I will take some measurements and better pictures, so I/we can figure out what I am building.

    As stated above I only cut the sides down and installed the blocks this morning. DA27FDBE-2382-4D0B-B859-00B69726DA70.jpeg EF5C3A78-672E-4F36-8D76-6BD750E3151E.jpeg

    The model mystery is solved. It is a J-45. He was not 100% sure last timed so we checked. Love that slope shouldered look. I am attempting to follow the look of the all mahogany J 45. White binding and dot neck.

    Finally able to work on this. The top is at the correct thickness now. We cut the sound hole and made the groove for the rosette. Then started cutting the top braces. I will now start scalloping the braces. 91CB2E46-E8AD-41FC-B433-7E8A248B24BE.jpeg 7B3422FC-4255-4EAC-9356-13C701C1911B.jpeg 247C7028-BB44-4FAB-B26D-78098FCCE97B.jpeg 25CD9297-958A-4BE9-83F6-282137516805.jpeg

    How thick did you go with the top? I've only built one all mahogany guitar but I absolutely love it - its just an incredible little blues box. Smaller air volume than yours will have and I was pretty aggressive with my scalloping but I'm really happy with the results

    .110 I am just now researching bracing and what scalloping changes can make. I take it that not taking the cross brace to the edge generates more volume/depth?

    I follow very traditional bracing patterns and I try to selectively weaken the braces where it seems to do the most good. I do a certain amount of tapping and flexing, which gives me good feeligs, but frankly I don't really know what I am doing. I have sat in seminars by several of the people I highly respect - they see to do things differently but towards the same goals. I try to emulate and learn with each guitar that I build.

    Tucking the ends of the X braces into the kerfing dramatically stiffens the top - most people do that. I also tuck the tone bars and the UTB but not the finger braces or popsicle - again, that is pretty standard. I do have a really nice set of plans for a J45 (it was on my list to build one) - they show 5/16 braces tucked and fairly heavily scalloped. Its interesting to me how much they are forward shifted. I'm sure you are either working from some plan or your luthier friend has developed something that works.

    Mahogany as a top wood is a little less stiff than spruce - that implies that maybe it should be a bit thicker and/or the braces a bit taller (stiffness goes up with the cube of height and only proportionally with width). For what it is worth, here is the insides of mine (it looks like I'm applying glue to the back kerfing ready to close the box)

    And the finished guitar - it is a tribute to those wonderful cheap Depression era guitars that so many of the old blues guys played. Several people have tried to buy it but it is just so much fun to play that I can't let it go

    There are differing schools of though concerning tucking the bracing under the top and not . Some will tuck the bridge plate under the X brace .
    Welcome to the bottomless pit .
    My first solo acoustic build was Mahogany topped .

    If you keep the tap tone frequency 1/2 tone apart when comparing top to back , it will help to prevent wolf tones . Whatever you do , you don't want them the same .
