  1. Re: Is the position of the braces on a mandolin important?

    I strongly believe they should be attached to the top of the mandolin.

  3. Re: How Do You Play Angeline the Baker and Why?

    Try it as a medley with Jolly Beggerman, Handsome Molly, and Down the Old Plank Road. They are all so similar, I do get mixed up sometimes...

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

    2020 was pretty much lutherie-free for me, as I had to re-learn how to do my day job. I had to redesign a 3-credit hour required class while in the middle of teaching it, and designed and ran three...
  6. Re: Rigel Mandolins not responding emails - tailpiece question

    That, too. Don't even need a CNC. Fair point, if all you have is a hammer, everything looks like a nail. :-)

    Superglue is a great fixture method for metal 2mm or thinner. In my machine shop we...
  7. Re: Rigel Mandolins not responding emails - tailpiece question

    This is a very easy part to make. Anyone with a CNC mill or router, a $20 set of digital calipers, and a fresh bottle of superglue can make these. Just use the broken one as a pattern, and you can...

    Re: Atlanta Mandolin Luthiers

    Yeah, it's a '64 Corvair. It was my daily driver for a couple years, my brother has it now. It needs some custom sheet metal work to get it right, and he's a sheet metal pro who sets up fancy German...

    Re: A vs. F

    It comes from confirmation bias, basically. It's not made up or imagined, but it's not a repeatable observation. The old "correlation does not imply causation".
    Test out a room full of mandolins,...

    Re: Kelley A-V-5 advice needed

    Looking at the pictures, it clearly got hot. As the OP knows, it's hot right now in Australia!

    It is irrelevant what glue joint was used. If it got this hot, it was going to fail, if not in the...

    Re: Equipment advice please

    16/32 is a great size. 10/20 is not worth it IMHO, my dual drum sander is 16" and that's just slightly narrow a lot of times. If you're doing any furniture, 10" is just not going to do it. Time is...
  13. Re: Building a new double-top mandolin by Yaron Naor

    Beautiful, Yaron. I may have asked this before, but do your instruments have the Kerman "chimneys" connecting the side sound holes to the back chamber? Would love to know your thoughts.

    Re: How to achieve a "warmer" sound?

    There is no one factor you should be worrying about. Or, the corollary: nobody can tell you one, or a few things you can do that will magically make this happen.
    Part of that is that none of us...

    Yep Tom, all good points. I was trying to give a sense of the relative difference in thicknesses I've arrived at between Sitka vs. Redwood, the numbers themselves are meaningless for Spencer's...

    Re: Flattop Top Thickness?

    Not necessarily. But you don't know anything about the wood you've got on hand, other than that it's lighter than what you used before. And the side depth and the soundhole area are easy to measure,...

    Re: Flattop Top Thickness?

    Ok, what does "darker tone" mean? To me it means, as a gross over-simplification, "Set the EQ to Bass Boost".
    So if you want it to really have those properties, consider reducing the size of the...

    Re: Flattop Top Thickness?

    The results from my redwood builds compared to spruce builds generalizes to redwood specs being about 25% thicker, glancing through ~20 instruments that I have the best notes on.

    I start out with...

    Re: Truss Rods vs Carbon Fiber?

    FWIW, a 1/16" diameter rod of 1144 steel would yield at over 300lb of tension (which would go up to over 1200lb yield strength for an 1/8" rod). So all of our truss rods are way overdesigned, by...
  21. Re: RIP: John Morton. Metal luthier master

    Aww, man. Always an inspiration to me, as a machinist and luthier myself (but never yet both at the same time). His instruments all look very timeless and original at the same time. A real master.

    Re: Truss Rods vs Carbon Fiber?

    I've only ever had to adjust truss rods on customer's mandolins if the customer (or someone in the past) messed with it or broke it.
    So I build mine with carbon fiber. Same reason I use a zero fret...

    Re: looking for Luthier near Atlanta, GA

    Thanks guys. Spencer, I think Tom's point was that he's a good half hour closer to the OP than I am... and I know his work is always set up as nicely as any instruments I've ever played!

    Re: Tailpiece busted - is this normal?

    Not very common! Just replace it, anything can fail. Shouldn't cost more than $30, but of course you can spend as much as you like on a replacement. Just don't expect a more expensive model to impact...
