Acoustic Guitar Construction

Why the plywood? Availability and economy. I don't own the hardwood, and I do own the nice plywood. Same stuff I made the neck and end blocks out of. I also think the ply tenon insert won't be as wont to split as a hardwood block when I install the threaded inserts or hangar bolts, but the operative word is 'think'. A materials engineer I ain't.

A lot I know, but it makes some kind of sense to me right now. Not like there is an acoustic component to whatever wood is used in the tenon.

A builder in my position, building for pleasure alone, can add complexity that would be unprofitable for a factory to do. I think, with no evidence at all, that the sainted dovetail persists in factories because of its low parts count, and if the geometry and trigonometry is built into jigs, very few shop operations are needed to make one. I suspect less scrappage occurs when there are fewer steps involving machines. A win for the 'traditional' factory, tout a cheaper part as an advantage and charge a premium for it.

Here is a link to a pretty good example although Mike Doolin's version is for an adjustable neck. It has pictures, which is good for me.

Doolin's presentation is worlds more professional and clear than anything I could offer. Looks like somebody smarter and more skilled (by a lot!) than me has worked this idea out very nicely.

Sometimes, it becomes apparent to me that there are people that are far more talented and intelligent than I...... And it really pisses me off!
