I've cracked the mechanism for my valentine's model! It's a bit slow so I need to make a faster gearing system but it actually works!
Inspiration for this goes to Paul Spooner who gave me an idea for an escapement mechanism. Pics to follow tomorrow.
I now have to wait until February to try and sell it though.
Sorry for the long gap between posts. Now that I've got the hard part of this model out of the way, I can hopefully finish it soon and start on my Christmas model.
