Thanks for the advice. I cut a holly log into 3/4" planks years ago straight after felling (for model building - holly has a lovely, almost microscopic grain), and they warped quite a bit. So it might have been a good idea to have left them in the log for a bit.
My concern over the half log is that it will dry from the outside inwards and when it is split into quarters one side of the quarter will be dryer (and hence will have contracted) compared with the side that was on the inside. This would then cause the 1/4 log to bend towards the dryer side?
Does that make sense?
Is there any way to combat that?
One thought was to make a saw cut into the back, say half way through, to allow air to get at the inside of the log, while holding the two quarters in place while they dry. That way, when I complete the cut, the quarters might be a bit more evenly dried around their circumference and less likely to warp.
Does that seem sensible?
