I would like suggestions for using Tempil

I want to anneal some brass necks. I would appreciate if experienced individuals could share their helpful experiences

Thanks in advance odavid

750 in the necks 425 halfway down the body

What annealler are you using?

I use the Giraud Cartridge Case Annealer

never tried hand annealing

 
I use junk brass of the same type for setting up . I paint the inside of the case neck with 750* and let it dry . if you paint the outside it will catch fire right away . aim the tourch at the neck shoulder junction . just as the tempalac melts my machine advances to the next case . my case is in the flame 4 or 5 seconds . after I get set up, I run my good brass . I don't use the 400* or 450* anymore . I never had a problem with heat traveling down the case that fast .
 
Thanks again guys.
I have heard this before. I have the 750* and was told to do the inside of the neck .
"I paint the inside of the case neck with 750* and let it dry . if you paint the outside it will catch fire right away . aim the tourch at the neck shoulder junction ".

I was told best to drop in water and be sure and change the water frequently to not let the water heat up changing the brass composition from getting into hot water but consistent cool water????

What are your thoughts on the water dunk obviously you both probably don't use water since you are probably air cooling from machine rotation.

Also does all of the tempil just burn off.... I really don't want to scrub it unless I have to.

Do you prep your cases afterwards or before???? case trimming before or after????

I do not drop them in water . the annealing stops when the brass moves away from the torch . I feel water dunking only adds another step in the process , drying the brass . I could put a try of water under my machines table but it's not needed . my machine holds the brass one spot after it leaves the flame . then it drops through a hole in the table . it's still very hot to touch , but brass cools quickly .

I saved a bunch of old brass , loose primer pockets , etc . I use this junk brass to get set up on , this way I don't have to clean the tempilac off my good brass .

I think it could be a pain to clean it off of good brass .

I tumble my brass first , then I anneal , then I size , trim , etc . I like to anneal clean brass , I can watch a heat line work down the case .

He is what I have done for years that you might consider. I take an old hand towel, wet in very thoroughly, wring out excess water, lay it out flat on my annealing table and drop fresh annealed hot brass onto the wet towel. It cools the brass down immediately and brass is dry in seconds.
 
Many thanks to all for sharing your actual experiences. I am hopeful others will follow and read these posting and move forward with clarity.

Thanks

I spin my cases with a battery operated drill in the flame of a single propane torch. Used Tempil to figure out how many seconds to spin case shoulder in the flame. Then I just place a clock with a second hand in the background and leave case shoulder in flame for the predetermined amount of time. The case head is held in the drill bit securely with a Lee case head holder w/adapter. When I remove the shoulder from the propane flame I continue to rotate the casing and touch the shoulder area down on top of a wet sponge that's situated in a convenient location for several seconds. The case will hiss like a hot iron and then cool very quickly to the point I can remove it from the Lee case head holder and place in on the table. Just keep the sponge well wetted with water. Whoever told you it's important to dunk the cases in water of the same temperature is full of it. The rate of cooling has little to no affect on the annealing of the brass. The time at your flame temperature is the critical part, which is what the Tempil helps determine. Too cool / too little time in the heat = no annealing. Too hot / too long in the flame = overannealed. There's some forgiveness in the proper heat/time zone.

In my propane torch with the flame set about 5/8" to 3/4" long, it requires about 5 1/2 - 5 3/4 seconds for .300 Win Mag size cases. Less time for .223. A little more for .375 Weatherby. Across all cartridge extremes the time in the flame varies from 5 - 6.5 seconds. I only used the Tempil to figure out the proper length of time in my propane torch flame. I basically never use the Tempil any more, as I now know about how many seconds in the flame is required for the various case sizes I anneal.

I've never thought it was all that easy to observe the Tempil melt. Others must have more calibrated eyes than I do. I've always found it tough to ID the very moment it melts / changes color. I'm probably spinning my case necks faster than the automated annealing machines, which makes it more difficult to observe the instant the Tempil melts. Good luck with it.

I just checked my Tempil and I purchased the 650F.

I only use Tempil on the first case and thereafter I count the time off on all cases thereafter. The reason is that if you put the Tempil on each case it is a problem to get it off all the cases afterwards. I have also found that larger cases requires longer time under the flame to have the Tempil melting. Smaller cases anneal much quicker. Then I also sort the brass by brand for the reason that some brands requires longer annealing than others. It has something to do with the brass composition.
