Instead of using the washers when you have just two gear bits, could you simply add another red gear to the structure? Seems to me it would add extra friction and so, would serve the same purpose. I tried it a couple of times and it seemed to work. What do you all think?

Yeah, but it takes space… But still, if you have lots of space, It might work!
The only space a gear would take up is an unslotted post, and most of them are never used. The issue in my mind is whether the gear would provide enough friction so that the washers would not be needed,

@DonV You are exactly right on that. A simple way to add friction without needing to put on the washers!
