The automata piece called "Fishing" that I completed earlier in the year requires a little rework! The mechanism in the centre left of the photo belowis the Geneva mechanism that causes a small fish to leap for the bait. The 1/4" thick plywood piece is the drive wheel and the 3/8" piece to the left of it is the star wheel. As you can see the drive wheel is not aligned correctly and binds on the pedestal (the stained 3/4" piece). The interference has gotten worse with this summer's humidity. It seems of a lack of clearance and the Geneva wheel not being installed squarely is the root of the problem.
The solution? Do some modest disassembly to gain access to the wheel and cut it off the drive shaft. Make a replacement, cut it in half with a fine saw, and splice it back together on the drive shaft. The original assembly was done with CA glue so removal of cams on either side to get the wheel is fairly involved.
Automata is a creative blend of my life interests , engineering, art and woodworking.
