AlphaFlyte,
Hopefully this will make some sense of part of the sketches. This is the start of the "fist" of the bot. The idea is to use set driven keys so that as it spins counter clockwise the chisel moves forward for use and when its spin clockwise the opposite tool would move forward for use, while the chisel returns to the home position. This shows both in the home position, which would occur when the fist rotates 90 degrees and both tools are parrallel to the ground. Okay, maybe this won't make sense of the sketches...

Metallicjet66, thanks for the support.
