robertdo Posted October 28, 2010 Author Report Share Posted October 28, 2010 I would bet that some plant geneticists would love to answer that question if they were to get funding for that... but my guess is that the flame is more an organised phenomenon than these bear claw marks. If you've seen some sweet corn completely yellow, sometimes they bear some red spots or trails, that is the mark of a transposon (a small bit of DNa that "jump" from one location on the chromosome to he other) Quote Link to comment Share on other sites More sharing options...
Don Noon Posted October 28, 2010 Report Share Posted October 28, 2010 Nice clear photo showing the ripple in the grain. Case closed. Quote Link to comment Share on other sites More sharing options...
Bernhard Ritschard Posted October 28, 2010 Report Share Posted October 28, 2010 Thats how it looks on endgrain: I have been told it's genetic, no bears, no insects... I like it if there are only a few of these bear claws, but too many of them stiffen the wood too much in transverse direction.

robertdo Posted October 28, 2010 Author Report Share Posted October 28, 2010 Yes bearclaw, but there could still be a conspiracy and photo switch. I am not good enough with my camera to do that... Maybe I would like these marks if there were more and spread over the all top, but there is only one large and it doesn't really appeal to me like that. One of the tonewood suppliers whose link appeared in the bosnian maple thread is selling some bear claw tops, so I might give a try one of these days. From what I read here and there, bear claw spruce is heavily used and well considered by guitars makers. Quote Link to comment Share on other sites More sharing options...
Janito Posted October 28, 2010 Report Share Posted October 28, 2010 There is no problem with your wood - enjoy it. Recall that many old violins have a wear channel in the varnish along the right side of the fingerboard. In 100 years, the bearclaw mark will be disguised by heavy usage.

I have seen more of this in Guadagnini than in other makers and to such an extent that I used to call them "Guadagnini marks" before I knew the correct terminology. When I started we didn't have the luxury of internet! Great photograph on the end grain. Bruce Quote Link to comment Share on other sites More sharing options...
