Abalone purfling is in, and all I need is one back binding to go on do some scraping sanding and its ready to finish!
Once again, the semi double top made a huge difference in the way to top rings.... deeper bass and sustain.
I'm very happy with it!

Tremendous work, Peter. But I wouldn't expect anything less from you.

Peter, Theoretically, will the double top be more resistant to changes brought about from RH extremes? Also, is there more of the redwood or more of the other?

Very nice, Peter.    I understand "double top", explain semi-double top, please.

The beautiful work continues.  Keep it up Peter.  That really looks great.  Your work inspires me.  Thanks for keeping us up on the progress.


Ron:

He had a pretty good explanation of the semi-double top in his last thread on this guitar, last week.

From my expirience with double tops, changes in humidity will affect these tops equally (unfortunately!)

Normally on Semi doubles, I leave more of the top layer unless real unstable or weak wood.

[QUOTE=peterm] [QUOTE=joe white] From my experience with double tops, changes in humidity will affect these tops equally (unfortunately!)[/QUOTE]It would be interesting to run the grain perpendicular on the inner layer. That could help, or make it worse.   It would be interesting to see what it would do to tone/sustain/bass etc.

Steve, after all the research I have done on double tops plus the few I wasted trying, running the grain perpendicular stiffens the too much and actually dampens a lot of the sound. No good....

Keep in mind, my semi-doubles inner layers are not solid but empty in areas that I believe help loosen the top and still keep is strength.
