We're d-18's scalloped or straight braced? Is the layout anything much different than found on the stewmac 'Herringbone' plans? Thanks... |

Depends on the year, but if Martin was scalloping D-28's, D-18 were pretty much the same |

For the back and sides, tops were about the same possibly lower grade for the D-18 If you want a really accurate print of a forward shifted, scalloped braced Martin, John Arnold has an excellent tracing of his 1937 Herringbone D-28. Its also an outstanding guide for a killer D-18. |

D-18: B&S mahogany Fretboard and bridge E Indian RW, Brazilian on earlier models Binding Black ABS or tortoise celluloid on earlier models D-28: B&S E Indian RW, Brazilian on earlier models FB & bridge ebony Binding white ABS or Ivoroid on earlier models Bracing was pretty much the same between the 18 and 28.

So how does one get a hold of the John Arnold tracing?? I understand that John is an expert concerning " red spruce " and he's considered one of the best guitar makers on a par with Wayne Henderson. Ed |

I have been helping with spec corrections on our 'prewar' model dreadnought - there are a lot of subtle differences between years of production. I would suggest getting a good tracing from Mr. John Arnold, which will accurately represent a specific 1930's instrument, while the Stewart MacDonald plans are a loose interpretation closer in specs to a 1985 HD-28 than a vintage D-28 (the D-18 differs in materials and trim...mahogany back and sides, red spruce top through about 1946, and sitka thereafter). Other changes include: - Bracing was scalloped thru the late 1930's, then scalloped and rearward shifted though the mid-1940's, then tapered for a time, prior to going to straight bracing by the early 1950's. - Nut width (1-3/4" thru late 1930's then 1-11/16") - Bridge pin spacing (2-5/16" narrowing to 2-1/8 when nut was narrowed) - Fretboard and bridge were originally ebony, then Brazilian, then East Indian. - Bridge changes included contours, moving pins rearward - Rosette changes, tuner changes, etc. If replicating an instrument, pick a year and do some research. |

Ed, I have one of the '70's D-18's from the "over built" era that has had the large rosewood bridgeplate replaced with a smaller maple one and some "after market" scalloping was done thru the sound hole. We did not remove the popsicle brace as is sometimes done. While I do not have before and after sound clips the subjective feeling is that the guitar did change - my wife's comment was "you are playing louder". At a local bluegrass jam it was played along side a D18GE and a 1937 D-18 (yeah, a real one) and the feeling was that it held its own. |

I think the popsicle braces should stay there... |
