3d Pantograph
I built my own carving copier to make rough outs of some of my finished carvings. Before there were copy machines and cameras, people made pantographs to copy their tracings of objects onto a flat surface. I keep one in my shop to enlarge outline drawings. It's pretty simple.
It turns out that people have been making 3D copiers or duplicators using routers for a long time. But, they are expensive. Some people have made their own designs, e.g. Copy Carver. They are good, but I had my own requirements.
Hand Made Tools
I made several carving tools to fit my needs. One, a "hooked skew" is very versatile and easy to use. I have made versions from a 1" spade bits and from portions of a sawmill bandsaw blade. The Woodmizer bandsaw blade is thinner and harder.
