Our model engineering club has a saying, "One project at a time". Don't think any of us stick to it as there always seems to be a hiatus between operations. SO, what to do with the glue set time" or silver solder pickle time? Why, "Just start on this little project" and the rot sets in.
Nice aim though?
Good luck with the carousel, they really look good when finished and running. Saw one at an almost, local (87km up the freeway), model exhibition a few years back..
