Thread: Annealing questions

oh and it looks like Skips making them for sale.

So log onto the website and access the page if you want to buy rather than make one.

Cheers

Good info Pete . Cheers for posting.

I might have a go at one of those. I'd use one motor linked to both shafts as you ideally want them spinning at the same speed to keep in sync. Just rotate one shaft relative to the other to get the relative timing as you want. Wouldn't need to buy anything.

Just be careful and watch a few YouTube clips one I watched the guy was getting the brass way to hot compared to the other clips I watched

How can u tell? Most of the YouTube ones show guys not using Tempilaq to indicate. I use a high temp (shoulder area/inside neck) and low temp (base) to set up and then once I have the timing right away I go. Personally know of a guy who overcooked the base - result, a dramatically expanded base and primer pocket and lots of gas trying to escape backwards/jammed bolt.

They were really glowing like in one clip where they domoed a couple of times what colour a case goes when its to hot

Yeh, crazy. YouTube is bloody dangerous.

I did a test to destruction on my annealer. Using 308 CAC brass I increased the heating time from 4 secs in 1/4 sec intervals up to 8 secs. The best result was at 4 1/4secs. At that point the Tempilaq was indicating all good and when viewing down the neck (room darkened) there was a momentary dull glow as the annealer indexed. You had to look hard to see it. The 8 secs ones had the neck glowing red for around 3 secs and the low temp Tempilac melted right down to the rim.
Interestingly I then did some ADI brass with similar neck thickness to the CAC and I had to change the 4 1/4 secs time by 1/4sec to get a result the same as the CAC.

@P38, roughly what size is the pan you use as a drum?

Thanks Pete. Though I'm from the 60's and prefer SI units.

Yeah where do you get the pan?
