[QUOTE="Pdvdh, post: 316991, member: 4191"] There are some historical threads on annealing case necks on this Forum. Run a search. The last one I saw was getting the necks hotter than I do. With a propane torch held at the junction of the neck and shoulder, I twist my cases in a battery powered drill for about 5 1/2 seconds. Then dip the case neck quickly in ice water. I've use a Lee case holder to hold the case head and chuck it up in my 14.4 volt battery powered drill. Then spin the case/shoulder in the propane flame for 5 1/2 seconds. I keep a clock with a second hand on the table for purposes of timing the heating cycle. 5 1/2 seconds is about right with the hottest tip of the flame adjusted to be about 3/4" out from the torch head. Then quickly dunk in the ice water to prevent heating up the case head area. Deprime the cases before annealing so you don't have any pressure or suction formed inside the case when you dunk the case mouth into the ice water. Simple as that. I determined the 5 1/2 seconds based on the use of the temperature crayons, plus the shade of the case necks after the annealing process. Also talked with Ken Markle of K&M Services and he told me on his propane torch he'd found about 5 to 5 1/2 second to be correct. That basically matched my findings also. The case should not be glowing red hot at all or you've overcooked the brass way too much. And the case neck will always be mushy soft after that. Practice on some throw away brass cases a little before you anneal your keeper cases. It's really not that difficult. But to do it the way I do it, you need the case to be held securely in the case holder that gets chucked into the battery operated drill. Good luck. [/QUOTE]
