I just tried Sam's plastic bag/heat gun technique out on a prop I have been struggling to complete. I must say it is much easier (and better looking) than the burlap fabric and latex glue I have been using..
I would also like to thank Sam for the plastic bag / heat gun technique. I have a my first corps thanks to him and it's looking very nice..... Decayed.... Yucky?
People if you choose to follow in his foot steps then Work in a well ventilated area.
Actually go outside!
A fan and an open basement door DOES NOT CUT IT!
Any chance we could get a better shot or a line drawing of the mechanism? I like the way you got a fast, non-linear motion from a wiper motor - almost pneumatic in speed. Not quite getting it from your description. Great job!
