Hey Everybody.
I'm a long time reader, and just decided to join the discussion. I followed many others as they discussed the thumbs on a Terramite. I finally decided on my path, and now the thumb is installed and fully operational. It is very cool. I can pick up massive cactus, really big stumps, and all sorts of other cool things. It will pluck bushes right out of the dirt....roots and all.

I realized the thumb placement is very important, so I needed to move it closer to the hinge point.
