Annealing ? where to put Tempilaq on brass

[Dubya]

New to annealing and have heard (read) to use tempilaq in different areas of brass.
Where should it be used?????

Thanks.

The area your annealing. Neck and shoulders.

Once you get a feel of how long it takes you wont use it anymore...

750 inside the neck and put some 450 outside 1/3 the way up from the base of the case.

Or 475º 3/8" below shoulder/case wall joint. I'm too nervous to allow that much heat too close the the case head. Been working for thousands of cases for me.

Thanks jet & watercam, at least you are on the same page.
How about residue from Tempilaq? What's the best way to remove it?

No need to remove it as you will want to use a donor case/cases to get the time down etc. Once you get the time down do the keepers.

Agree. I set aside a few donor cases for each lot/batch of brass used

if using a torch, inside the neck. you can put it on the outside if using induction.

That's the technique I use too. Saw it first in a YouTube video - think by the 6.5 Guys, but I may be mistaken. I started with Jet's method in post #3, but found it very difficult to judge when the green 750-deg Tempilaq had just melted (or even if it had melted).

I had the same issue with the 750 deg Tempilaq on the inside of the neck. I ended up using 400 deg Tempilaq painted in a stripe from the shoulder to the base. When the 400 deg melted to about 1/2 way down the case of my 6 BRX, I found the brass properties to be where I wanted them. I use an old case or two with only the Tempilaq on the outside to set up my annealing machine. It takes about 2 minutes.

Thanks guys. A lot of different opinions.
Guess I will have to work with a few to find out which is best with gear that I have.

I do the same way Jet does . 750* inside the neck . I do recommend using 400 or 450 on the case body until you get the hang of it . I did when I first started annealing , but I don't bother any more . I've never had a problem getting the lower case body hot, since the case is only in the flame about 6 seconds . I don't have any short case ammo , 308 family would be my shortest . the short cases are the ones I'd be worried about heating the case head to much , so I would watch the heat traveling down the case with tempilaq . I also use a few pieces of scrap brass to set up on .

Sounds like you need to dip the whole case on the first one! Lol
I do believe that clean cases will be the best for uniform annealing. When I heat steel I see this at my work. Dirt deflects the flame from the material.

 

[shoot4fun]

I always clean before annealing. I used Tempilaq in the very beginning but now I don't need it. BTW, I was putting the 750˚ outside and 450˚ above the case head.

I didn't think the 750 did melt, I thought it only turned colour green to black? Which is why I gave up using it. The 450 would melt and turn clear.

I keep the test cases for all calibers in one container in case I need them fro set up again. Throw them all in the tumbler to clean them sometimes.

If the tumbler can't remove it then spin and .0000 steel wool will clean them quick.
