Annealing Anyone?

just curious, has anyone built or thought about building a case annealing machine? I'm thinking about building one. been looking around and found a few ideas on what components that I will need.
I got a wiper motor,power supply and a 30 amp PWM to control the speed. with a couple of propane torch tips I believe i can make one.

I have been playing with the idea of making one - I need very high volumes and so the problem (for me) is a LOT of torch heads, cuz I figure I need to do about one a second with a 6 to 10 second flame dwell time (using propane).

I was hoping to use MAPP, and 5 or 6 flame heads, but MAPP has has been discontinued, and I don't want to go with compressed gas for cost and safety... so I think I'm looking at 9 or 10 flame heads (

) and that gets expensive, so I have stalled on the project for now.
 
thats a nice setup Reddog, i found a hunk of aluminum thats 12in x 12in x 1 in thick. I'm planning on taking it to a metal fabricator down by me to have him cut a circle out of it and drill the holes for the cases and a center bearing.

Catshooter, have you seen the machine Mike Bellm has?
Mike Bellm

it looks expensive though.
 
Isn't one of the tricks to annealing brass rifle cases to have sufficient heat to heat the neck and shoulder up to temp. with out over heating the rest of the body of the case???

That's interesting - but I need to do cases from 38 SP to 50-BMG. I will probably need a few machines... and the cases must spin fast when in the flames, so it is going to be a P.I.T.A. no matter how it is designed.

thats the reason i want to go with a aluminum disk thats 1 in thick, it will dissipate the heat from the case body while allowing the neck and shoulder to reach the temperature you want. if you have a PWM you can control the time the case stays in the flame. some templic and a few trash cases you should be able to set the timing just right for the case your annealing.
 
Catshooter you got your work cut out for you,hopefully you will find something that will work for you.

yes it does, but the price tag is a little out of my range.

I'm glad you mentioned the Giraud annealer. I didn't know that they made one.

It has a bunch of features that meet my needs... speed is not one of them, but - first off, to run unattended (well, be in the same room, but do other stuff). And be able to load a bunch of cases and walk away.

None of the rotary machines had an auto feed feature, and I had thought of rigging up a Dillon case feeder to one.

But I could get by with a Giraud for a while, and then if needs got heavier, get one or two more.

P.S... if you want an annealing machine, you have little choice price wise - they are all $300 to $500.

If money is tight, you can't beat the Hornady kit.

 
The Giraud is considerably cheaper than the Grizzlyworks annealer. One of these days I'll have one to keep my trimmer company.
