I am also a woodworker and do not like the 21 in 1 tools (PUN). Yes, the 9C will thread left or right. The spindle hole is 3/4 inch. This machine also has back gears. I believe that the slowest speed is around 45 or 50 RPM. Top speed is up around 600 RPM. As I mentioned earlier, this is a great starter lathe as long as it is in decent shape.
