[:o)]YES I’ve burnt my fingers, how do you stretch sprue nice and even?. Thanks for any help[:(]…Kenny
Hehe…First thing to understand, sprue is limitless, so you have plenty to practice with. Use a small candle, rotate the sprue (hold with both hands while doing this, otherwise when it droops, one end will fall into the flame) slowly waiting for the area over the flame to turn waxy then slowly…SLOWLY…pull the two ends in opposite direction until desired length is achieved. If you screw up and pull too fast or something else unfortold happens you can start again. Just takes a couple of minutes of messing around to become a pro. Enjoy. [;)]
Wolfp is correct.
By turning the sprue, you are trying to get a uniform temperature to the plastic. If the sprue doesnt stretch, you need to keep it over the flame longer. It needs to be more of a liquid than a solid to stretch.
I hope this helps.

And after you’ve stretced the stuff, still holding the ENDS of the piece you started with, let it cool for about 5 minutes, just to be safe.
