I worked the handle and fades as close to finished as they will get for now. I floor tillered the bow as close to perfect as I could get it. I prefer to have my bows floor tillered, or even long string tillered prior to any sinew or heat treating being done. I feel your less likely to get a suprise off your caul that way. I then sanded the entire bow down with 60 grit and rounded the edges more. If you keep the surfaces you intned on heating up smooth wou are more likely to get a good, even temeper job and less burnt frays. I use a cheap Wagner two-stage gun for all my dry heat work. I start at the fades and work towards the tips, clamping as I go. In this case I moved my gun HALF its diameter every 90 seconds or so. This gave me the color I wanted and hopefully the temper I want. Every build is different so be sure to experiment some until the color you want comes around. I went 20" up the limb and stopped. I see no good reason to heat treat a portion of the limb not working much. You will notice a clamp on the opposing limb. I learned the hard way a while back that bows rock in that caul. The first limb I would do came off basically straight while the second would be highly reflexed.....hmmmm Einstein? I now place a clamp on that side to prevent the rocking and get a perfectly even reflex. I did one limb today and will finish the other tomorrow. Im whipped.
