I usually try and get the tips to 1 ring on the belly side if possible, my form for flipping the tips are single so I do 1 at a time, I put the form in the vice and then mount the tip in it, I add a weight to the opposite end of the bow and heat the tip I want to flip slowly and let gravity and the weight pull it down, rarely boil, sometimes get a little check but not usually, I leave the tip a little thick and can most times scrap it out. I will try and put up some pictures when I get home to maybe make it clearer. Pappy
