Finally have the augur put together for a test run. Here are some pictures of it in the explosion view and assembly.
I use stove rope soaked in oil for the packing on the shaft. Cut out a piece of cutting board for the inside plate.
Here it is all assembled and after the test run.
The charcoal that I’m using has pieces double the size of popcorn which might be a little to big. But after going through the augur it seems to be more the right size.
My thought is 2 of these augurs back to back tied together with a pully and hollow shaft with set screws and the a single drill motor with a belt pully to drive it. All controlled from the driver’s cab.
Videos will follow.
