I might only add that when I did mine, I did NOT get it hot enough, and I did crack the lens. No loss for me though, because I wanted it to go in a CTC-9 with external glass anyway. The hardest part, in my experience (one experience only to date), is that those "fingers" of air go away fast! The whole project took me about an hour steady. I had not used the halogen lamp preheat, so I'll do that next time. I have a 1 Kw halogen dual-head lamp, so I bet that'll be even better.
AND A SAFETY NOTE 
ABSOLUTELY, POSITIVELY, USE SAFETY GLASSES AND FACE PROTECTION! I WORE A FULL-FACE MOTORCYCLE HELMET, MOTOCROSS CHEST PROTECTOR AND NECK WRAP. I KNOW IT SOUNDS NERDISH, BUT BELIEVE ME IF THAT TUBE FAILS WITH THE GLASS NOT ATTACHED, THERE WILL BE SHARDS OF GLASS THE SIZE OF SAMURAI SWORDS HITTING YOU IN THE FACE, FRONT OF BODY AND THROAT.
There must have been some kind of official tool for this purpose, and there were CRT rebuilders all over the place. I can think of a half dozen in the West Los Angeles area. Some of them were just one oven and lathe in the back of a regular TV repair shop (such as West Coast TV repair on Sepulveda Bl in Culver City). So we should all keep an eye for articles, and for any stuff like that on eBay.
