This definitely was the most satisfying wooden model I’ve built so far. My clock can now easily run continuously for 12 hours, and the time is only off by less than 5 mins. Pretty impressive for this type of clock!
It only took me ~4 evenings to build it, but after that it took me a week to troubleshoot the issues. In this review I’ll mainly talk about my lessons learned. Hopefully they will be useful to some of you.
1. I used a thin putty knife to check if the frame is pressing against any gear (I think a long cutter blade will work, too). You want to reduce friction between all moving parts as much as you can. In my case, I had to loose up a couple pieces slightly so that all the gears can turn smoothly.
2. When my clock stopped running, I checked the gears one at a time to figure out which one was stuck and how. In my case, at the beginning of each hour, after the hot air balloon descended, sometimes gear #133 stopped at a bad position. A couple minutes later, gear #63 would got stuck with gear #133.
- I figured I need to move the fishing line connecting to the hot air balloon a bit to the left, so that gear #133 would stop at a better position after the hot air balloon descended. I added a paper clip wire to two existing holes, and that completely fixed the issue. See the attached picture.
3. At the beginning my clock could only run for ~ half an hour. I thought it would be a good idea to add wood lubricant (for drawers) to all the gears. BIG MISTAKE! The lubricant is a little bit sticky, which caused my clock to stopped completely within a few minutes. It took me days to remove most of the lubricant. Use candle wax instead to lubricate the gears.
4. I filled up the sandbag all the way to the top. A heavier sandbag helps to overcome friction between the moving parts.
