Deans book "Hunting the Osage bow" was a game changer for me, particularly on how to handle fresh cut osage properly. I started using his bow designs but didn't use the facet tillering he recommended in his book. I called to order one of his bowyer's edge tools, he answered the phone, we talked bows, bow making and hunting for quite a while.
When I first started out making bows I experimented with a lot of whacky ideas and posted my results on the Stickbow site. Dean saw my posts and said that I "was an insult to the true art of bow making", he wasn't trying to be humorous, he was dead serious. This rubbed me the wrong way at the time but looking back, he was probably right.
At the time Dean said this, I thought I could come up with some better bow making processes than the old masters, after ruining a lot of good osage I found out I was dead wrong. I did come up with the Tillering gizmo during this experimentation phase so it wasn't a complete waste of time.
