The fish feeder has a really neat clutch mechanism that allows you to modifiy the drum in 5 minute increments. This will also work well as a servo-saver, just incase somethig bad happens – I don’t want to strip out my servo or the gearing.
Here you can see half the clutch mechanism and a standard servo bracket.
A little too much time with a side-cutters and a dremel left me with a hole too big, and a servo-mount too small. They don’t seat well to each other. The servo-mount is only slightly larger then the hole, and there are no flat surfaces to match up. It just wobbles around in the hole like a bobblehead doll.
As Terry Hansford always used to say, “I’ve cut it 3 times and it’s STILL too short!” I chopped up another servo bracket a little less aggresivly this time. It is still slightly small, but with a little bit of Epoxy, it should work.
The finished product. The epoxy tube says 24 hours before it is done curing, so in 8 hours, I am going to be playing with it *grin*. I think this will work, I now have a clutch that can be mounted to a servo.
