"Esstern" wrote in message ... I've been offered some spruce for spars that's pretty much perfect in every way except there's 21 rings per inch instead of the recommended 12-15. Good stuff or no? I don't really see the problem with finer grain spruce and in fact, can't even remember where iread it's advisable to use 12=15 rings per inch. The more rings per inch the slower the growth. The slower the growth the better. 12 to 15 rings per inch is the minimum recommended in ANC14. Highflyer
