I have a cuckoo clock that is about 20 years old. It has a simple wooden stick with a weight that is attached to it with a crimped piece of sheet metal. You adjust the speed by sliding the weight up or down the stick assuming that it stays in place. Well, it no longer does (stay in place). Not to mention that it is very finicky to adjust - I'd really like to know that 1/2 turn = 2 minutes per week or whatever it comes out to, rather than "slide it up a whisker to make it faster"...
I'd like to retrofit a mechanism that uses a screw, but maintain the look of the simple cuckoo clock design. Pics as follows:
