It seems to me, that long term curing does seem to have an affect. I've managed to make white wood bows in about a week. However, they were only so-so shooters, and followed the string slightly more than I would have wanted on average- even though they were at an acceptable MC. I have also made bows from other bows, or roughed out staves, that have been sitting around from six to twelve months, or more. These seemed to work better (the wood responded to the tools in a better manner) and stabilize (especially during tillering) more quickly- like Pappy said. Up until now, I just thought it was me though
.
However, the variation between woods seems quite dramatic. Red oak seems to have reached this "stage"
much more quickly than hickory or white oak- red oak reached it in about six months or so, where as hickory can take uo to and over a year to reach it. It also seems to be affected by the size of the stave, and the size of tree that it came from (smaller trees seem to reach it more quickly).
I've got several sister staves, two of which are being "quick cured" in slightly over a month or two, the rest will be set aside for much longer. I'll see if there is any big difference. I'd also like to check how "Indian" bows (small trees roughed out quickly into whitewood bows) age.
