Interesting solution! I had tried the long pins and found that the end I
wanted to stay stayed for the most part...but it wasn't reliable.
Increasing the friction of one end is a novel idea indeed. I may just use
it in the end. The option of making everything big enough to fit the
transmission assembly is, sadly, out of the question. I have a very limited
number of parts and no money to acquire more :) Thanks again for the
suggestion!
