  On this one there is not Mark.  I have started putting as large a gap as possible on subsequent mandos, just need to make sure there is no gap at the bridge area.  I also stopped leaving them open, the sound is not as good, and the hinges wear out of you leave them open.

  Interesting. Is there no gap between the soundboard and neck/stick?

  Here are some additional pictures, hopefully you can see the details I described in my last post better.

  Hi Mark,

  I just felt like most CBMs I have seen had a really boring flat neck.  I wanted to replicate the way a curved top mando has the fretboard floating in the air.  Just felt right.  My first mando was the My Father the Judge dark brown box, the neck was flat, and it was missing something.  I loved the look of the second mando, the white mando, although the angle was really exaggerated.  The last 3 I built felt like they were the perfect balance.  The only structural support I use is a small 1/2 inch square corner brace in all 4 corners with whatever scrap wood I have.  All are neck through, but the wood I use in the through neck and the corner braces is always less than would be had I built the box up and used a bolt on neck.  I also designed a small L brace on the end of the tailpiece that prevents the string tension from crushing either the box or the neck.  I believe the sound is the best possible from a cigar box.  I have messed up a couple of mandos, so it has been trial and error.  But if I can give any advice, please let me know.

  Basically just think of the neck as the entire load bearing piece, and the box is just the sound board and reverb device.  Each neck has 2 scarf joints.  The first is the headstock, the second starts where the neck enters the box and allows the fingerboard to float off the box top.  Both are around 6-10 degrees.  I dont have a large tablesaw, so have had to adapt a not-so-perfect jig and sand away any errors.

  I cant carry a tune, but I will try to post some sound/video in the future.

  Hi Thomas!

  I noticed that several of your builds incorporate high bridges and generous neck set angles.

  I'd like to know more about your box bracing and general construction design, as far as managing the large string load. 

  Nice looking builds, love to know more and hear them.

  Have not seen any posts here for a while.  Thought I would show my 5, 8 string mandos.  By far my favorite thing to build, sound amazing.

  My first mandolin build- a four-string Punch box just like the previous post.  My goal was to build an angry-looking little mandolin just right for playing folky/Celtic punk (checkout Flatfoot 56's "Knuckles Up").

  My 1st Mandolin.  I used Aquila Soprano Fifths 30U strings tuned GDAE.  Thanks to Uncle John, I am only using two fingers for the chords.  The Rod Peizo/Pre-Amp works great, not that I play well enough to want anyone to hear me.  Play it almost every day.  I also have a concert size CBU (wider neck at the nut) with the same strings, that I like even better, because it gives me more finger room and I don't have as much buzz and dead strings.

  I just bought my first mandolin. An Ibanez A style. Now that I have my blueprint I'll be building shortly after my license plate doubled string resonator with mag pup is done. Do most usually go with a wider neck than a standard mando?

  Standard mando strings (GDAE) tuned GDGD- actually less pressure.
