Minor update. Since I am waiting on some parts for the front, I decided to build the ring feeder. Still a work in progress. I need to put more thought into how the pin will work, manual, or servo etc...
It's a little bit over sized, but it will do for now.
Sorry, that's all the photos I got, the battery in the phone went flat.
I also started on dismantling an old bike to harvest the sprockets and chains for a slew system for the crane I want to mount on the back.
