Acoustic Guitar Construction

I really like the way RR looks and also there's much less of a chance for chip out when not notching for the brace ends -- and there is no denying the rim holds its shape once the RR is installed to the sides

I used reversed rounded lining on the Ditson Kit I received from you. I like it and have added it to my must use list. The little extra step of misting and clamping is worth it.

I really like reversed linings. Easier to make,easier to glue,no blow outs when notching,looks cleaner even if less traditional. The only type I use now. I will share a light bulb moment I had last winter using reverse lining. I glued a top on a dread,I glue the top on first so one can work on the braces if need be, after drying I gave the top a nice rap to test the sound. Nice tone but very clearly in the sound was a rattle like a cracked rough top that you tap. I looked every where in that top to find something that was loose or cracked. Four and a half hours later I finally discovered what the problem was. The linings were made from Spanish Cedar and when I made them the slots were cut a bit deeper than normal. Somewhere along the way one of small bits holding the individual blocks together broke and left a small crack across the lining. Through all the close lookin I just happened to notice it. A quick shot of CA glue,another rap on the top and the rattle was gone. Next time I'm kerfing linings the slots will not be so deep.

Tom is correct regarding the inletting of the braces -- even when using a router the traditional triangular kerfing can shatter in an instant. And his "light bulb moment does make that point as well that with RR kerfing, much deeper channels can be machined without the fear of the top or back plate becoming unattached -- yes, I've not done that myself but indeed read horror stories of such an incident.

One more benefit of reverse kerfed linings. When I made my Manzer wedge OM, I really needed to sand the rim on a radius dish to get it so the back would mount easily. I foolishly glued in the linings before I contoured the rim in the dish so I had a lot of work to do to get the whole rim to sit flush in the radius dish. With reverse round linings, it was a non issue. Even taking the linings down by 50% of their height does not result in a loss of gluing surface and you still have enough meat on them to put on traditional height bindings. With traditional linings, there would not have been enough glue surface left for the back plate to mount on. Saved my bacon for sure.
I hope that makes sense. Reading it back, I am not so sure!
Whatever. RR linings are the bomb. The bees knees. The shizzle. They are good.
