A number of weeks ago I posted a preview of this Canadian made rotary annealer. We now have a final version in production so I am making this post again for those who are interested.
The annealer now comes with movable, multiposition torch supports, and a gear drive that runs at 1.3 rpm. The standard unit can fit 4 different case sizes (223, .308, 6.5-264 and Magnum, but any specific size can be made as a special order
You can also specify only one size case if you desire.
For long cases we recommend the use of extension bushings as shown in the last video.
The first 3 photos are of the prototype, the last picture on the green background is of the final version
PM me for details or interest.

Price is $450 + HST and Shipping
Torches are not included

My only question would be how do you know the brass has been heated enough to anneal? As I understand it, it needs to hit a specific temp (700 degrees IIRC) without heating too far down the case; the timing is less important than the temperature. There's supposed to be a product called (I think) Tempilac that is put on the case that will turn color when the brass hits the right temp.

Has this been checked with brass out of this annealer? If so, I'd look at purchasing one...

You are correct, you need to do your set up with tempilaq, I use 750 on the shoulder and set up until it melts. You can either use scrap cases for this or just clean the tempilaq off after. Once you have set up the system you do not need anymore tempilaq, you just feed the cases in until you are done.

You need to set it up initially with tempilaq for each session.

Generally this takes me about 15 minutes.

Lots more info here....

That is why the annealer has either a way to adjust the speed of rotation and/or adj the flame so that the case experience the correct amount and duration of heat.

It does take some set up and that is for ANY mechanical annealer. However, when done, it's well....DONE.

I check on each session as the propane torches are not exactly precision devices and the pressure in those propane canisters do drop.

I have a batch of 'dead' brass that I throw some tempilac on (750F) to confirm thing are running as they should. I will on occasion check during a long run as pressure to the torches can drop.

Beyond that, these mechanical annealers are a god send for both speed and repeatability.

The unit pictured looks very well made and robust to last a lifetime of useage.
