    DIY Annealing

    So... DIY annealing.... anyone care to share their tips and tricks? Seems a fair bit of contradictory info on the web as to best method. Was thinking of doing the blow torch and drill method as I only have a small number to do. Really want to maximize the case life of my norma 280 brass as its expensive but obviously dont want to cook it! Dont have enough to justify sending it off to be done.

    For a cheap setup...
    - Deprime without resizing.
    - Stand up in a row in a longish tray of water (or in a circular tray on a lazy Susan) ~2/3 of case bodies submerged.
    - Move blowtorch along from neck to neck.
    -Only THEN resize.

    Only real danger is accidentally annealing cartridge bases and you are safe this way from doing that.
    As for annealing differences between cartridges (you know, those hypnotic machines on youtube that do it precisely the same way for each case), I understand the case necks are either annealed or they are not, and with the water method you can safely give them a good blast to the neck and shoulder.
    They will cool rapid-ish if standing in water, but speed of cooling does not affect annealing, either you got the neck hot enough to soften it (read: undo the work hardening from repeated re-sizings) or you didn't.

    I use the deep socket method, no dramas. different brass goes at different temps. You may need to sacrifice one to get the timing. I use about 10 secs for 308 type cases but only 6 secs for .222 and strangely 270 Win

    Best tip ... do it in a dull room so you can better see the colour change

    Socket method works well mounted in a drill in the vice
    Do it with the light off. You will notice the slight yellow/blue change in colour. That's when you need to stop.
    Angle the drill so you can flick them out while still turning with a screwdriver so that they land in a metal tin.
    You can then do it rapidly

    Great informative video, but he still went ahead and resized before annealing.

    Much as you dislike the option of spending too much money on the process, I would urge you (and everybody else who does not yet understand the process) to read this https://www.accurateshooter.com/tech...les/annealing/
    Then bookmark it so you can read it again!
    It is an exacting process and if done properly will achieve the desired outcome. If not, it will achieve nothing, in that no correction has taken place, or worse, destruction of the case, which can not be undone. And you have no way of knowing!

    I had a Ken Light machine but moved on to the NZ made AMP. No setting up, no naked flame/s, perfection every time.
    If the cost seems to be too much, get some of your buddies together and buy one as a co-operative. Each to use as they need, and only necessary to buy the collets that each person has need of. Above all, understand what the process is and the possible dangerous outcomes.

    I have pretty much finished building my DIY machine, based of Skips design on YouTube. It has cost me about $180 with almost $100 of that being the propane torch and hose. I initially planned on using those small disposable propane bottles they come with but have changed to LPG to get more consistent pressure from a larger bottle and way cheaper. I also ended up buying 750F Tempilaq which was about $70 on NZ (couldn’t be bothered dealing with shipping etc. from Brownells).

    I think this has turned out to be a consistent and hassle free method. There were are few teething problems whilst building it though!!!!
