View Full Version : plate thickness

11-25-2011, 02:51 AM
I'm getting ready for my first build, probably a tenor or concert.
And I am wondering about a starting point for top/back thickness.
I am going to use the siminoff tap tuning method that I have been happy with for guitar building. It will be an all koa, unfigured build except I have the option of a sitka, adi, or WR cedar top.
as much as I love the look of the koa tops, I assumber it would not be as bright a sound.

Start at about 2.25 mm... .090". Also consider your bracing pattern.

Would that thickness apply whether it is koa or the softwoods?

Yes, cedar is not as strong or dense so it needs to be a bit thicker. My plates are in the .070's". and like Rick said... consider your bracing pattern.

I go with Eric. I have a sign on my drum thickness sander..."It's stiffness, not thickness". Two trees growing right next to each other of the same specie can have quite different stiffness.

Wood from the same tree does not necessarily have the same stiffness.
