Annie annealer time settings

[loneranger04]

I use my Annie for three cases, 6BRX, 284 WIN and 7X57.

I have experimented with both core spacings and various times while monitoring with 750 Tempilaq as well as brass glow with subdued lighting.
i found that while a bit slower, the wide spaced core seems to have a bigger flux concentration area so I get the tip all the way to a bit below the shoulder area pretty evenly heated. The 6BRX of course is only 1.8 sec or so, the 7X57 about 2.5 sec and the 284 Win about 2.8 sec.
The narrower core spacing makes for a tighter flux concentration with higher flux density so it heats faster, but it heats a smaller area.

Thanks for the info. I'll try that.

Mike you mentioned you are not turning the necks, then the next time you anneal them the time will be different, Thinner brass. I always turn my necks first then Anneal! If you anneal then turn the necks, they will have a different feel when cutting them.

I set mine up this week.

I am only doing .223 and found the best setting for Lapua brass is 1.8. Best for RWS and General Dynamics is 1.6. All necks were turned before purchase of the Annie. Tempelaq 750 for narrowing down the setting.

One tip on the Annie water reservoir system. It needs to be primed. After monumental consternation, the way I solve the problem was to fill up the jar to the top, carefully turned it over with all electric disconnected (obviously) until the tubes were filled, refilled the jar and turned it on. No more problems.

2.6 seconds for my 308 lapua thick neck brass.
I hold the shoulder in the middle of the coe, if i dont the neck gets too hot and glowing red while the shoulder doesnt get enough heat.

Here are my Annie times, checked with 750 Tempilac.

223 1.8 sec
22-250 2.7
30-06 1.8
7mm Mag 1.9
6mmBR 2.5

I have no explanation for the time variation, nor do I have any concern. The case in coil location is fixed by pins in the platform height mechanism. The 223 and the 22-250 use the same height, so the shoulder junction is not in the coil center for both. The same is true of the 30-06 and 7mmMag. The 6mmBR is at it's own location. In every case the annealing goes to just below the shoulder, and is extremely repeatable.

This is with the water cooled coil.

I find it interesting that there is a variation of up to .5 seconds for a particular case, i.e. .223.

I imagine it has to do with manufacturing variations in the particular coil that is being used when compared to other same coils, or variations in the inside diameter of the helical coil itself. My inside diameter is way longer than the minimum clearance of 1/16" in the manual.

 

[Mr Underbridge]

The annealer is shipped with 2 different ferrite cores and some are using the water cooled coil..
So big differences

 

[Fotheringill]

To avoid misinterpretation of my data, I have the Helical water cooled coil.

I was wondering what others are seeing for anneal times for the Annie? I have only done about 50 cases so far and was wondering what settings others are using for various cases. I have annealed thousands of cases with a benchsource but the results are a little different with the annie since there is no flame leaving much if any coloration.

The picture is of some cull blue box 6br brass from various stages of forming dasher cases and annealed with the annie and 650 tempilac. necks are not turned. In a completely dark room I see the necks just start to glow about 3.2 seconds. anything less than 2.0 and I don't see the tempilac consistantly turn color on all of the neck.

I did some 260 lapua at 2.3 seconds and the neck tension was cut from about 50-60 lb to 18-24 seating force on my hydro seater and seated very nice.

If you see red I am sure you are stress releaving. Why 650F TempLac? No annealing takes place even at 800F for a couple seconds. Templac is not intended to be used with a 2000F flame on it. From my experience, hardness testing and real data I would says your doing OK at the time and temp your doing.

Look at Erick Cortina's video on flame annealing and seating pressure measurements.

According to The University of Illinois annealing study 30 seconds at 450C (= 842F) gave a slight hardness change. I believe these were 1/8" thick plates cold rolled to different degrees of cold work and annealed in a furnace. Again if your seeing red you are annealing to the temp almost everyone agrees on. If you anneal much longer beyond first seeing red you are approaching getting to hot.
