Yep. We used to tell the friend beginning to rush his bow along, to go get a bucket of water. When asked what he was to do with that bucket of water, we'd reply for him to stick his head in it. The idea of course, was to slow down. Another saying was, "It does not matter to the wood, how long it takes to make the bow."
I liked Gstoneberg's reply. He's right. Sometimes with a bunch of wood on the pile, we take it a bit for granted. If we only had one or two pieces, we might be more cautious as you are being. Nice bow so far. Keep up the good work and keep us updated with pics.
