Early 1900's Style Flatback Mandolin Plan

I’ve not started building yet but the plans look sufficient.

It is a little premature to review dreadnought plans. I have some Cocobolo and killer soundboard wood sized for a dreadnought These plans look pretty spot on from what I've used via Stewmac's herringbone plans (basically same plans), but are $11 less expensive. I just need the bracing layout as a starting point. I have good side bending forms and the molds for a dreadnought. I will vary bridge, brace shape/scallop, headstock shape, etc. I will go with a Martin scale neck/fingerboard fret slotting. I have some other guitars in progress and haven't got to this guitar yet. It's been a while since I've built a dreadnought styled guitar.

Not quite for me. Not considerable for actually building a violin to specifics, but it does have measurements. Great for a conversation piece or enthusiast to frame and hang in your library. The notes can be vague and surely could have included helpful information. If you're rebuilding after an apocalypse, it would get you in the ball park, but much like a dinosaur, there's just information missing from know exactly what is what.
