Hello All,
Here are some photos of the new tailstock I made for my 4th axis. Turning is very ridged with no deflection, as far as the mach up compression bolt I made. As usual, only time will tell with a new project. I plan to make a motor adaptor plate next, so I can mount a variable speed motor for better CNC lathe work. The best part of each component (4th Axis - Tail Stock - tooling plate) is that set up is a snap. Each, started upside down with a .260-W x .025-D channel that I mounted a guide block in. Then the base of each, was flipped over and the guide block seated into the center t-slot in the table. I located the center of the table (Y-axis) and the center of the base (X-axis) and completed the work. I drilled holes in the tooling plate for .125 pins. I can now load the plate, seat the taig vise up against two pins, and be within .0005 of square.
Thank you for viewing,
Ken Polley
