In my opinion, heat treating/toasting bow bellys is an advanced technique best left until after you have mastered the basics. But heat treating has become the new "sinew backing", another advanced technique.
It seems we all came to bow making with the desire to make a great bow, not realizing we could make A LOT OF BOWS on the way to making that great bow, and we all seemed to want that first one to be as good as it could possibly be. I am dealing with a potential student that I believe has that innate "something", but I cannot get her to commit to starting the bow, just keeps recalculating what the penultimate most bestest is supposed to be. Three years and she has not touched a tool or a stave.
Perfect is the enemy of good. Robert Watson-Watt, who developed early warning radar in Britain to counter the Luftwaffe, argued for a "cult of the imperfect", which he stated as "Give them the third best to go on with; the second best comes too late, the best never comes."
