Visual inspection will be fine...no splits, checks, delamination or warping. I have worked on violins that were in excess of 200 years old, the spruce tops, which take a lot of abuse, are generally as good as the day they were built. An ocassional slight check or crack on the spar might be repaired simply by glueing on plywood webs as on the opposite side of the spar. If the spar has been varnished, you will have to sand that off before glueing webs on... but being sure to varnish the inside before attaching plywood. Any enclosed spaces should have 1/8 holes drilled in the new web to provide breathing room. ----- Original Message ----- From: <clarkma1...@wmconnect.com> To: <kr...@mylist.net> Sent: Saturday, January 22, 2005 9:38 PM Subject: KR> Wood Spars
