Thread: A few spare minutes this afternoon. Induction Annealing

Got a bit bored this arvo so made a very Rough induction annealing circuit out of stuff lying around my bench.
Built the coil from some scrap Coax cable

Works OK, draws 5 amps in "standby" and about 8 with 223 case in the coil.

Wanted to test it before buying a proper diy kit.



With case



Still needs work but 20 seconds in the coil will heat 223 case almost red hot.
Need more work but looks like will work OK

Cool Mikee .

Hook it up on the progressive press?

Yeah the station after dropping the powder😆

Dunno if I would have that sort of heat near any primer or powder.
Defeats the speed of a progressive as well.

You wouldnt want to get your ring finger in there. What frequency does it run at?

not sure I haven't hooked up the scope yet.
I can buy a kit that does the same thing but as its 150 euros I wanted to test the theory first.
Resonant frequency is a wee bit low in my circuit as its not heating quite fast enough yet. But then since I really built it out of odds and sods and ............................. didn't really do any calculations its working OK for now.

Coils on the kit are hollow and can be water cooled

I was thinking hook up a stepper motor and adustable timer to lift a case into the coil and out with and adjustable pause in the coil.

In a compleatly seperate operation to loading of course, just use it as a case feeder.
1000 cases in the hopper, turn on, go drink beer, come back when done and turn it off

A DIY version of this is what I am hoping to eventually end up with

Thats cool but turn it on and walk away is cooler.

I'm sure I could make a case feeder for it too So far parts for a proper water cooled on are going to run me about 400 so might be a while before further progress is made on the fully auto one

Also brought a cheap 24inch Cresent today for difficult jobs / customers
One of those days

I prefer the 36 inch pipe wrench or the 8lb Birmingham screwdriver from Supercheap.......Old school sizes but no one argues the point to your face....

very cool you didnt explain this spare time concept please tell me more

Well customers seem to be getting the message from management (manager and service coordinator that we don't actually want or need them. So it makes it sometimes a little quiet out the back in the Service Dept so we need to find stuff to do to prevent the boredom winning.
