Would anyone be interested in an affordable, UK made induction annealing machine?

[Bavarianbrit]

The Annie has open coils, and as Aris pointed out, it looks like something that Wallace made (as in Grommet), so is unlikely to appear in the UK anytime soon.
You say you don't want an open coil but if the coils are water cooled, what is the problem?
Even the Quick Anneal and AMP dispense hot brass, so this is never going to be child safe. Reloading in general is not child safe. In fact, nothing much in a workshop is child safe: not just grinders, lathes and mills but even things that look safe like presses are lethal if used inappropriately. Even a hand file can kill someone (use a big file as a crowbar, or use it without a handle then slip).

BTW: this afternoon I spent 15 minutes making a mumetal jacket for the outside of the water cooled coil to try out when the cooler arrives, as that should intensify the field within the coil by shortening the magnetic path. Ferrites can do the same job. Will see how much it heats up from the losses from its magnetic hysteresis.

The thread is becoming a bit of a PM 1:2 chat, so I will go quiet until my cooler arrives and I post some pictures for anyone else who wants to build an annealer.

Ref the safety aspect in a reloading room, after 50 years in engineering this small danger point struck me last week so before I stumble and poke an eye out here is a use for an old whisky cork for the sizing spuds threaded rod.

For those that already do annealing can I ask two questions.
How many reloads do you get from new brass if not annealing on average?
How many reloads do you get from new brass if you are annealing on average?

( Or I should of said how many extra times can you reload brass if you anneal?)

Here is a modified basic gas annealing tip for using in a drill.

Or here is a smaller gas annealer machine from Serbia. I have bought mine (bigger) from the Bulgarian chappie but this might be of interest to someone.

Back to gas methinks

There is also a Scottish bloke named Bruce who has adapted a PC cabinet to make a pretty nice annealer. But again I don't trust myself to fiddle around with these things and not get electrocuted:

Nice to put a face to the name

Thanks Steve, yes I am pleased to report that my engineering pal is progressing well with his development work on the induction annealing machine. At the moment he is testing out different induction coil geometries and has decided to make the machine with a top mounted auto feed carousel big enough automatically to process a batch of 30 cartridge cases in one go. The holes in the carousel will be sized to accommodate cases up to and including .308 and similar sized diameter case heads (such as .243, 6.5 Creedmoor and so on). He is also thinking about making a carousel with magnum sized holes available to buy as an optional extra if anyone wants to anneal large cases like .338 Lapua Magnum. So if anyone interested in annealing magnum cases in the machine please do let me know in this thread and I will do my best to encourage him to offer this large sized carousel.

Happy New Year!

Hi HandB, and a rather late “Happy New Year” to you too Sir!! .
Whenever your friend gets to finalising a test model or some such I’d be happy to give it a run from a very interested party’s side. My main cartridges are 6.5Swede and .223Rem though I have a couple of other small case rifle cartridges that I load for. FYI the Swede is approx the size as a slightly stretched .308 case with - as near as damn it - the same size case-head diameter.

I look forward to hearing more regarding this so please do keep me in the loop here Mr. Hand.!?
“Speak to the Hand”….??

Special Regards,

One of the previous posts states that he anneals after resizing.
Surely the brass does most of its ‘stretching’ during the resizing process ? Therefore I thought you needed to anneal before resizing. I’m willing to be educated on this if people know better.

Just had 100 cleaned and annealed by Spud.
A bargain, Ken.

When do you temper a blade?

Hiya Klench, good to be back yapping with you again! Been a while eh?
The thing is with that blade making analogy you put forward is that you aren’t tempering a whole batch of blades at one time that have each had a potentially different life of use - unless one is a large Commercial concern - to then do stuff to them afterwards.
Where brass is concerned there is a possibility that it might be from different previous loadings and batches etc and yet the idea of our reloading process is to at least attempt to get every case as close to identical each other as possible. I am certain that to this point you and I are in 100% agreement (I hope?).

But if the cases are from different, previous load batches etc it is entirely possible that the actual levels of work hardness of each could and will be a little different to one another. This may be due to having been loaded more often or with much different & stiffer loads (read internal working pressures etc).. If the cases are all then sized first and THEN annealed the actual “spring-back” in the cases - necks in particular- could potentially be different, yes??
The subsequent annealing process in your suggested methodology would then hopefully align all the case brass for hardness, BUT that won’t address the potential for cases to be in a slightly differing range of measurement where the neck SIZE is concerned due to my previous suggestion..???

I would (and do) anneal first and THEN resize the cases (necks in particular) when they are ALL at the same level of temper and therefore more likely to come back to near identical measurement subsequent to the NEXT STEP - of SIZING..

Anyway, that’s how my mind works and how I manage those couple of tasks Dear Sir….

Happy to be converted given as of writing I’ve yet to anneal a single case.

I am however in the process of prepping some Sako PPC brass prior to shipping for just such treatment as after seating a bullet, with plenty of neck resistance, the bullets can be removed with finger pressure. With some the process of simply removing a loaded round from the box leaves you with bullet in hand and spilled powder everywhere!

Upon your guidance I’ll leave applying neck tension c/o a bushing die until the cases are returned from Satan’s workshop in a suitably compliant state.

Why pm?. surely Spud advertises his prices???

 

[aris]

Stumbled upon this which looks interesting if you want to try and DIY it

Some people eh 243ack. Spud wants his services advertised as much as possible. https://1967spud.com/case-prep/annealing?brand=4

He definitely DIY'd it - not sure anyone would want to copy it though

Cheers

Why not? If you have the skills - looks doable.

Sorry, late to the party but I am interested. Currently looking to buy an annealer, how is the project coming along?

Yes however the case will be somewhat work hardened some when annealed . Think of is as a reset . Can work either way though its all about degree , good brass can take a fair bit of re-sizing without the process. Pre - annealing good brass was and still is good for say ten sizings
