SW Florida is a different beast from Utah in the humidity department'. It'll be interesting to see how it does.
Russell, I do coat the whole limb in Crisco before I heat it.
My heat gun has a temperature dial and I set it medium and slowly work in the heat all around the limb so it penetrates. Certainly, I don't concentrate the heat too much on the back of the bow but I do glance over it and the sides, but the belly gets the lion's share. Make sure the limbs aren't too thick, as stated. That was my biggest mistake when I was starting out. Sand everything perfectly SMOOTH and go!
Did a little more scraping last night to get the blank closer to ground tiller now that the recurves have changed everything.
Here are some pictures. Also, you can see how the whoop-dee-doo influenced the recurve, but it looks pretty good to me.
Check out my neon pink and chartreuse arrows with tamarack shafting. Should match up well.
