Hi All,

Does anyone know a source to purchase some Tempilaq in the GTA, or Richmond Hill, Aurora area? I would like to try my hand at annealing, finding a source for tempilaq by searching google has been a challenge. I tried Acklands=Grainger, no luck searching... but maybe they carry it anyway... I find some sites search engines to be less than stellar.

Thanks for your help. :canadaFlag:

That said what I do is stand my cases up in a pan of water and just heat the necks with a propane torch. I use the water level to set the distance down the case that I wish to anneal. Since you're annealing and not tempering I don't know that tempilaq really will do much for you other than cost money and time as all you're doing is heating the necks till they glow and calling it a day(essentially). If you're that fussy than you can pay attention to the colors on the brass as well as they do show with heating.
 
Basically the procedure for annealing is: stand the cases in water to the annealing line, heat the brass with a propane torch till dull red, tip over the cases into the water. Before you try to track down Tempilaq, sacrifice a few cases & see if the above technique works for you. It's not rocket science. If you're not happy then go the Tempilaq route but it looks like a typical Occam's razor situation to me.
 
why clean brass will tell you when its done when you get a blue color on the neck into the water it go's I do this even with my .577-450 brass and that cost $5 a piece

a socket that holds the case while letting it slip out put that on a drill with a deep pan of water by your feet spin the case when it gets the blue color tip into water(ps it will only show blue in good light)

glowing red is not good BTW that's too hot
 
Appreciate the help. I have youtubed many videos, I would like to try and be a little more precise than just eyeballing it. After an hour or more on the phone, Tempilaq is not a stocked or easy to find item.
 
"...its done when you get a blue coloUr..." Nope. It's done when the brass changes colour. Blue hot is too hot too.
"...try and be a little more precise..." Isn't necessary. You do not need anything other than tap water, a metal pan and a propane torch.

Not in your area but Acklands-Grainger should have it. I find the temp sticks a bit more useful. I use a Bench-Source annealing machine and Markall temp pens. I use the 450-F for most cartridge conversions and the 550-F to anneal fired cases. I guess annealing setup would dictate what temp indicator works best.
 
When you use the pens, do you mark the case before heating and wait for the pen transfer to melt whereby you consider the case annealed, or do you heat the case and then mark with the pen to see if the pen transfer melts.

I am just wondering if the results of tempilak are valid if you end up exposing the pen to high flame heat as oppose to marking the brass after and seeing if it reached the appropriate temperature?

With Markall temp pens being a hard wax compound heat test out of flame is required. Tempilaq is messy and if used on cartridge exterior is exposed to flame, if used inside neck it would be out of flame but would cause other problems. The instruction manual that came with Bench-Source annealer suggests the use of Tempilaq only, but the sticks are easy to use and results are repeatable.
 
ive never used any of it and im playing with some expensive cases here unless you annealing some high dollar nitro express brass I don't see a point take some cheap and easy to find cases and practice
 
Yes its trial and error until you know required time in flame, but if you start low and don't exceed temp limits sacrificial brass may be zero. What are you using for annealing? The Bench-Source is a two torch rotary table system with a programmable timer that controls time in flame with a dial setting. I record the timer setting on load data sheets for cartridges that require annealing and that's about all there is to it. Just check a couple cases during the annealing process to confirm temp and its good to do 100 cases in 20-30 minutes.
 
I am making a machine similar to the one below. I will only be doing it on 308 brass. Its not that I am really concerned with the cost of wrecking a couple cases, just want to know the most effective way to know that my time spent in front of this machine payed off. I have seen alot of youtube videos of people WAY OVER annealing a piece of brass, and others that aren't heating the brass even close to long enough.

I use the socket and drill trick
Choose a long socket that fits the case properly, allowing it to turn but not tight.
turn the case above the flame with the drill, then dump in a pan, then start again.
Takes approx 8 seconds for a 300 winmag case neck.
you will see the line going down the neck, stop when the line is at the shoulder. You do not really see the case glowing.
I've seen numerous youtube videos of people completely toasting cases.

just read this and do it. no need to piss your pants really, just do it properly.
