First thing I need to do is clean the brass before I de-prime it.
Here is a before shot:
Added 30 rounds to each drum, added water and 1 TSP Lemi Shine powder:
Started them spinning for about an hour:
I have the ultrasonic cleaner as well so I thought I would give it a shot same recipe as above, 30 rounds, 2 sets of 8 minutes with heat.
Here we have the results:
Left = Ultrasonic
Center = Before cleaning
Right = Tumbler
All with only Lemi Shine. They both look good to me.
Then I bake them at 150 for 5 minutes
Another shot after the first cleaning. Bottom ultrasonic, top tumbler:
I followed the below:
IN each tumbler drum I put:
1 ½ lb of stainless steel media (at the most)
About 1 lb of brass
Water up to the lip or just below
Lemi-shine (1/4 teaspoon)
Squirt of Dawn (enough that when you open the drum you see soap suds)
Tumble for 2 hours.
Here is a shot of the brass from above:
After using the updated method:
