Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

DIY brass case annealing machine

#1 Post by Rapidrob » Tue Apr 02, 2019 7:55 pm

I built a machine following the instructions on Youtube under " DIY Case annealing machine for 100 bucks"
I changed a few things:
Made a case holder/spinner from a emergency car radio antenna.
Added a DC voltage display
used a power supply from an old computer ( more current)
Added a water resistant ON/OFF Switch
Use his part numbers as most of the parts are the same or cheaper to buy EXCEPT the case. Mauser site is gone. Amazon has the case for 49 bucks sans his for 35 bucks.
Stop his vidio and get the complete part numbers and names. Easy to do and no part took longer than two days to get to me.
I had to make my own case holder as plated and galvanized parts give off nasty fumes when heated. The antenna is S-Steel.
The cake pans are first rate and are not the El-Cheapo ones you find at W-World. They absorb heat like noting I've seen before.
Timing is controlled by drum speed. Cases spin in the drum and are evenly heated. Case bases are not heated to become soft.
No hopper for me. I will not leave an unattended open flame. A case is done ever 5-7 seconds depending on size. As soon as a case is fed,plop on another one to wait it's turn.
I did one over sized case so you can see the annealing area/lines
My cost was right around 85 bucks.Shipping was free for all parts.

case in drum against holder. This is the correct position to spin and drop. About 5 o'clock in the drum.

To old to fight and to old to run, a Jar head will just shoot and be done with you.
