Hey,
Just started a new build for a good friend of mine. Will be an OM 28 style steel string, but with a few differences, the main one being my own body design which is slightly smaller than Martin's OM shape.
Engelmann Spruce top - a really creamy, tight grained piece
Indian Rosewood back and sides
Honduras Mahogany neck
Indian Rosewood fretboard and bridge
Herringbone purfling & rosette
Ivoroid bindings
Trying to get everything perfect on this build. The last 14th fret spruce model I made in this shape came out a bit stiff, so I am going to take the bracing down more at the edges, and I have also used normal kerfing (rather than stiffer, reversed kerfing)
At about 2.8mm. Sounds 'floppy' now it is down to thickness, but once it is braced it will come alive again.
Can't even count the grain lines.
Prepping braces.
15 foot radius for the back. Only 3 back braces as the size is smaller than a typical OM.
I am eager to try a go bar deck, but for now I glue one or two braces at a time, and really clamp the hell out of it.
The spruce for the X brace is super dense and straight grained. Will remove a lot more material.
For the headstock veneer and end graft I have done book matched rosewood pieces.
Routing the saddle slot with a cobbled together jig. I go for a 3mm wide saddle slot. I have done wider but not convinced on the intonation benefits.
Marking out bridge pin holes (55mm string spacing). I need to make a template for this ... The holes follow the slant of the saddle slot.
Next weekend I should be closing the box and getting the neck in rough shape.
Cheers and hope you're all well !
