finished the auto annealer today

[rvpilot76]

Just a thought..........
How about using this same machine to heat treat boolits. Adjust flame, speed, etc and drop the boolits into a bucket of water. Hmmmmmmmmmm.....just a thought.

Don't think that would work. The flame heat is too focused and localized. The heat needs to "soak" and normalize thoughout the boolit for the heat treatment to be uniform.

that is great I see or read something new here all the time tanks.

[cajun shooter]

You would have a machine full of melted lead!

[Dale53]

Definitely a pretty piece of work!

Thanks for sharing with us.

Very well engineered Mr. Morris.

[jmorris]

I have a fresh batch of "blades" if anyone is interested in putting one together shoot me a pm.

[chuck...]

Have you considered a 4 second cycle instead of 8 seconds? Or did you use templaq ((700 deg or 750 deg) to decide on the cycle time?

cheers,
chuck...

[jmorris]

The cycle time depends on how the torches are adjusted and what brass is being annealed. It's always a little different.

[jonblack]

Boy, the ingenuity you see always amazes me. Great work! I may have to put one of these together "just cuz."

A router speed control from Harbor Freight would allow easy adjustment of the dwell time. Of course you would have to shorten the dwell time to begin with, then you could lengthen it by slowing down the motor.

I just so happen to have an extra mounting arm for my 650 case feeder. Hmm...thinking about doing this project just for fun...

I used a DC motor and a dimmer swtich for the dash lights on an old RX-7 for the speed control. If you are wanting to put one together I have about 10 of the blades left.

[saigafan2008]

Awesome job, Mr. Morris!

May I ask where you bought the motor?

Thanks,

Carl

From Granger. The link to all of the step by step photos is in the first post.

Jmorris,
AWESOME!!!!! I have a couple of questions, how did you find out how long the brass needs to have heat???
Also, I don't kmow anything about the properties of Brass, but if those were made out of steel they would harden when dropped in water. So brass doesn't get harded with fast cooling??
Your machine is as I stated AWESOME design, and thanks for sharing.

Templaq, is the best method for knowing what temperature you are reaching.

The only thing that hardens brass is working it. The dunking in water you often read about is to make sure the base doesn’t get annealed. I don’t use water in my process as it is not necessary and would just add another step in the process to dry them off.

[gcollins]

Thanks J,
Like I said I didn't know anything about brass. Thanks for the link, I am trying learn what I need to know, I have just put toghter a AR in 243WSSM and i am told the WSSM brass doesn't do well if you don't anneal it before resizing.
Thanks

I really need to make me one of these.

[jmorris]

I still have some of the blades left.

[DCM]

Very nicely done and "full auto" once adjusted!

[.30/30 Guy]

I just ordered a blade. There are still some available.

[WilNsc]

Very creative, might have to duplicate one this spring.
