Mick Miller Posted January 20, 2016 Report Share Posted January 20, 2016 Looks great, not sure if I'd want to be getting support from Poland if and when it went wrong though. Interestingly, whilst 'Googling' I also found this video on a more familiar technique - the comments below made for some thought provoking reading.... "Aaron Abbott The only thing I see done 'Correctly' is the temp paint,Which doing one case at a time is required with each case.Open flame changes chemical property of the brass,Which probably doesn't matter with extremely small batch processing since they will fail from other improper handling.Electrical induction heating, with brass sitting in a heat sink, water or tight fitting dies, will keep thermal transfer creep from happening and softening the case walls so they don't separate.Induction heating won't introduce hydrocarbons into the brass, or burn away metallic components in the brass.Induction also controls heat uniformly through out the brass, not overheating the exterior."

Mick Miller Posted January 21, 2016 Author Report Share Posted January 21, 2016 The point this commenter was making was that the time honoured method of using a flame actually destroys the brass as the zinc will reach vapor point in a direct flame and, I guess, gas off. Anyone else ever heard this? Link to comment Share on other sites More sharing options...
gbal Posted January 21, 2016 Report Share Posted January 21, 2016 Check out the "Annealing Made Perfect" approach and rationale (electromagnetic emmission control). This machine can be set up for specific cartridges,and brand of brass (they differ metalurgically-perhaps one flame/current does not fit all!) gbal Link to comment Share on other sites More sharing options...
Mick Miller Posted January 21, 2016 Author Report Share Posted January 21, 2016 Is that a you tube video gbal? Or a thread on UKV? By the way, the induction annealer I found being sold over in Germany (they have a version of 'eBay' just for shooting sales), it's a snip at a mere 1500euros.

gbal Posted January 21, 2016 Report Share Posted January 21, 2016 "Anealing Made Perfect" is the company-New Zealand from accents,just Google it.There is info and a demo video. I didn't see any independent validation of their point about brass differences,but it's the kind of detail some get excited about,and it may extend case life.....

The Gun Pimp Posted January 21, 2016 Report Share Posted January 21, 2016 There's one on show at the Shot Show - $995 Link to comment Share on other sites More sharing options...
Mick Miller Posted January 21, 2016 Author Report Share Posted January 21, 2016 Bargain! As every other man and his dog has been annealing by flame, without any obvious issues if sensible precautions are observed and adhered to, I think I'll do the same. At least until the price drops to a point whereby it actually becomes viable to use inductions without requiring that you shoot 2000 rounds every quarter.

Mick Miller Posted January 21, 2016 Author Report Share Posted January 21, 2016 In all honesty, that's a dogs dinner of an induction add-on; if I had the money or reason to spend that amount of money, I'd go for the Annealing Made Perfect unit every time (not that it matters as Giraud won't export to the UK anyway).

clivej Posted January 21, 2016 Report Share Posted January 21, 2016 I'm just getting all the parts together to make an induction coil annealing machine. Watch this space If I can make this www.minimcqueen.com I can surely make the annealing machine Link to comment Share on other sites More sharing options...
Chris-NZ Posted January 22, 2016 Report Share Posted January 22, 2016 I'm lucky enough to have access to a custom inductive system in the NZ Hunter workshop. It's based on an American commercial unit but the big difference is it's had a variable timer unit added by my now-deceased gunsmith who was originally an electrical fitter. The coil is mounted inverted above a reloading press ram so the brass is consistently positioned each time. The rather counter-intuitive thing is smaller brass takes a longer time to heat up that bigger cartridges, probably a proximity thing to the coil. I ran all my 6x47L brass through it recently and it does a great job. Gas obviously works but mains power is easier.. Link to comment Share on other sites More sharing options...
bewsh Posted January 30, 2016 Report Share Posted January 30, 2016 I bought Second hand mini ductor from the states http://www.amazon.com/Induction-Innovations-ICT-MD-700-Mini-Ductor-Magnetic/dp/B008XN9HO6/ref=pd_bxgy_263_img_2?ie=UTF8&refRID=0HXGB9NH5PEJ4J29FKD5 Cost me $90! Never got round to using it, not as simple to set up a case feeder for continuous use There is a video on YouTube showing it in use Simple Link to comment Share on other sites More sharing options...
Chris-NZ Posted January 30, 2016 Report Share Posted January 30, 2016 Do they have a 240V version?? I see that one is 120 Link to comment Share on other sites More sharing options...
bewsh Posted January 31, 2016 Report Share Posted January 31, 2016 Do they have a 240V version?? I see that one is 120 doubt it they seem predominately marketed in the US easy to run off a builder's inverter though they come up used now and then Link to comment Share on other sites More sharing options...
