naw, boiling works great, and it's pretty easy. if you use a blow torch or something really hot (i used a model airplane iron first), you risk burning the base or melting it. by boiling, it's just the perfect temp to bend nicely. just use a big ol pot, and set the tips up on some stools or a ladder so you don't have to hold them. boil them for like 10 min, then stick em in a vice and bend.
Word up to all the subie owners out there!
