    Re: I want to build a mandolin

    I was fortunate to have friends who let my borrow tools, or borrow the use of large power tools when I was in your position of just wanting to go through the process. I wasn't looking for a career in...

    Re: Was just gifted a 1906 mandolin

    Check the brace (there's only one, running crosswise just inside the sound hole) to be sure that both ends are securely glued, check for loose seams everywhere, check the frets and the bow in the...

    Re: Tell me why not: Carbon fiber bracing.

    Might be able to release epoxy joints by heating the CF brace.
    Many years ago, I epoxied oversize bone point protectors onto an F5-style mandolin. When the epoxy fully cured I started grinding the...

    Re: Tell me why not: Carbon fiber bracing.

    Many people simply carve the braces off rather than release the glue joint.

    Re: Post a picture of what's on your bench?

    Reaction wood (also called compression grain) comes from a stressed, off-balance tree. Often, a spruce tree will grow on a steep mountainside. Each year of the trees youth, it will lean a little down...

    I see the forum software didn't like my attachments again. I'll try once more to see if they will work.

    Re: Post a picture of what's on your bench?

    We're using the snakehead shape for the peghead, but it will have a custom inlay when I get it done. As of now I have the logo ready to inlay and I'm slowly working on the main inlay design. We chose...

    Rather than using mahogany for the head and tail blocks we went with a much lighter head block wood (paulownia) and a heavier tail block wood (hard maple) to help with the balance of the instrument....

    Re: question on restoring an old gibson

    Not enough info to answer the question.
    Are you thinking of replacing with an arched top?
    The neck angle should be very different for a flat top as opposed to an arched top, so depending upon the...

    Re: Tell me why not: Carbon fiber bracing.

    While the fundamental mode of motion of a top or back is sort of like a speaker cone, there are more modes of motion as well, and all are involved in the mandolin making sound. In other words, the...

    Re: Tell me why not: Carbon fiber bracing.

    Nasty dust, difficult to glue. Other than that, the main thing is getting a wide enough brace to have enough surface at the glue joint for a good joint, while keeping the brace light in weight. ...

    In the $1000 and down price ranges there is little or no consistency. Playing and choosing is the only sensible thing to do IMO if better sound is what you are looking for. I've found Kentucky...

    I don't know how many slotted pegheads you've done, but I would assume the builder went solid to save work and time! :cool:
