Some progress has been made. The carriage has been made to .003 tolerances, which is about the thickness of a piece of typing paper. The reason it is being built to high precision is that unlike a bowl turner, we work with very small pieces of wood. I want to be able to use router and engraving bits in sizes from 1/64" and up.
The driving screw is ACME 1/2" X 10 TPI. The carriage length, from bracket to bracket is 12". Longitudinal movement will be about 8". The wood parts that you see in the pic are only temporary for testing. They are being replaced with metal.
I am working on the first tool holder and in/out mechanism, which will hold a regular Dremel (current model available at most stores). The plate that will sit on top of the sliders can be customized to hold different rotary tools.
The first prototype should be ready in about 2 weeks. If all goes well, I will probably have a few ready in about 4 weeks.
