Cello fixin’

Here’s a Chinese cello I got off Craig’s List for a song. It had been de-strung before a cross-country move. The soundpost shifted, and then an impact split the cheesy, but solid and hand-carved spruce top in a few places. Looked like a straightforward repair, and I’ve been wanting a cello, so I picked it […]

c1915 Weymann Keystone State Mandolute – Restored

Here’s a Weymann I just finished cleaning up. It had a major top seam separation, several top and back plate seam separations. It got a new nut, fret work, the usual. This was my first real vintage restoration on a real instrument. I haven’t done a lot of repair or restoration, but I received this […]

Revisiting the 5-string electric mandolin / mandola…

That extra C string is getting a lot of interest lately. And this post from last year is getting a lot of visits from people looking for 5-string electric instruments. So I thought it might be time to dust off the ideas for a 5-string electric. Here’s where they are headed… with a splittable Alumitones […]

New neck machining process

So I’ve spent most of this week developing an improved neck machining process, refining the design of the necks to correct a couple little things which have bothered me about them, and developing a new “long neck” neck variant that results in bridge position more like the “Ms. Griffith” Loar A-5. I don’t know if […]

Summer 2013 Batch underway, and sold out

The summer 2013 batch is well underway. All the instruments are also spoken for. No pressure! Laminated necks — #22 on the left/upper, the other one is probably going to be used on a personal instrument due to the inconsistency in the coloring.     Highly figured Makore for block inlays and headstocks on #24 […]

#17 mark II… Now tell me that ain’t cool.

#17 mark II is finally delivered! Mark did a nice write-up of the process in this MandolinCafe thread. Thanks to Mark for his patience as I built him one instrument (#17 mark I), then scrapped that one, and built another (#17 mark II), encountering numerous delays along the way. I made four fretboards, carved four […]

British Isles tunes on #21 from David Mold (OldSausage)

Some awesome renditions of Irish and Scottish tunes courtesy of David Mold and the MandolinCafe Song of the Week group. David’s playing Jacobson Nautilus #21, one of the two Black Tie mandolins, and making it sound great!

Atlanta MandolinCafe Mando Tasting at the shop

Partly to show off some recently completed instruments, I invited several mandolin enthusiasts and MandolinCafe members from the Atlanta area. The gents generously brought several of their mandolins, some of them very valuable, some of them very rare, but all of them very interesting – and put them out for everyone to experience. I believe […]

Toy nylon-string mandolin for my kids

So… this is a toy mandolin / ukelele thing I made for my kids. It’s got a solid cherry top, solid cherry back and sides, and a curly maple neck. Shaped like an archtop Telecaster, obviously. The frets are machined right into the fretboard. It sounds like a shoe box with some rubber bands on […]

Spraying nitrocellulose lacquer on #17mkII and #18. #17mkII will also have a french polished top. The depth of the bubinga, maple, and mahogany are really starting to sparkle.

Nautilus Mandolin side bending fixture, Version 13

This fixture is the 13th version I have built over the past year. In this case, thirteen is a very lucky number! It is repeatable, controllable, easy to use, quick, and does not consume air or power in order to operate. I can finally move on to gearing up for my octave mandolin and mandola […]

Latent projects: GBOM

A friend reminded me of this project, a Guitar Bodied Octave Mandolin (could also be an Irish Bouzouki or Mandocello). Started it last year, got distracted building my CNC machine, and then I realized I would do a lot of things differently now that I have the CNC machine. So I may, or may not […]
