Your designs ideas are great. Since you are good at templating, could you have used a router to save yourself some sanding. Also if you can get a CNC like Xcarve etc... you could make toys with complex designs.
Thanks mate, you definitely said what I thought. It was a lot harder than I thought it would be. Some parts are too small to cut and I need to do a lot of sanding work as you said. How I wish I had a CNC. I would consider buying one if I have more projects like this to do.
