Crobots - Retrobot

I have finished Retrobot, which is also the last of the "easy" crobots to do.  (They are rated on a scale of one cogwheel to four, one being the easiest)  I didn't have the valves to put on for the arms, but I used some screws in place of them.  I am starting to find, the more I do of the crobots, the easier they seem to be.  I guess it is true, practice makes perfect!
