Awesome thread! This helped me win a contract yesterday. I used 3/8 x 1/2. The center tip cooled to quickly to forge alone and kept breaking the center off. I ended up using the hot cut technique that John describes, but only 2 cuts to separate the three points. I forged a taper with all three still together. Then I necked down just below the cuts as suggested(not enough). I had to upset the center to keep it from thinning out too much. Now that I've done this I have some ideas I'm going to put in the fire to see if I can make it look even better, since I'm not 100% satisfied with the results yet. (will I ever be? probably not.) Happy forging!
