Here is what it looks like installed. I need to sort out a shaft coupling. I have no idea if the motors will be powerful enough though.
I also made some feet for my Darwin to stop it scratching the table: -
I stuck felt pads, that I happened to have, on them, but rubber would probably be better for non slip.
