PVC Drum Agitator for Harbor Freight Dual Drum Rock Tumbler
Description
NOTE: First test results: Make sure you install the agitator so the cups are pointed in the clockwise direction when looking down the open tube. If the agitator is oriented that the scoops work in the direction of rotation then you can get brass stuck in them and those brass pieces don't get fully worked. Good news is after 1 hrs tumbling the pipe full of 5.56 and 45acp brass came out cleaner then when in the rubber drums for 1.5 hours. I started tumbling my 45acp brass with a HF dual drum rotary tumbler and found the rubber drums rather annoying to take apart and reassemble. I was inspired by this youtuber's PVC pipe drum https://www.youtube.com/watch?v=roN67_oGpx8 I wanted to make an agitator that was 3d printable without supports and press fits into the 4" pipe so all you have to do is: 1) Cut the 4" foam core PVC pipe 9.25" long 2) Glue in the 4" knock out plug 3) Stuff the 3d Printed agitator in 4) get to tumbling.
