So, work progressed on the tumbler yesterday.
Trying to figure out the cheapest easiest way to mount the bearing (timing idler). For once in my life I lucked out. It matched a hole saw that I had laying in a bucket! So the mount was built with a 2x6 with a hole drilled in, slotted, and a big GRK screw to pinch it in place!

Which eventually allowed me to reconfigure the design completely. A few pieces of scrap 2x lumber and osb, and good to go. Took the old gear head motor case and rotated the gear head and end cap to 90 degrees. Then mounted that, and made a quick extension shaft to the drive bolt with a hex that drives the socket and lug nut. Pictures are worth a thousand words...

This thing isn't industrial, and probably won't last very long. It's nearly full of old chain and driveway gravel, which is beating the living daylights out of the bucket, bearing, and drive. If this fails I might switch over to a belt drive from the gearbox to the bucket pivot. But, it might live long enough to do the trick.
First time trying a video. Hopefully it uploads and displays properly.
