That looks like a nice machine. Did you get any additional gears with it?
I have a very early model Legacy Mill. It was built out of all steel. I upgraded it several years ago with 80/20 top rails & a Legacy router support. I made a few projects with it. Tables & lamps with a rope design. It was in storage for several years. I got it out over the winter with hopes of doing some more projects with it, but work got in the way. I am going to semi retire later this year. I plan to learn how to use it again.
There are a few videos on youtube on the older mills. Do a search for them.
I will try to help if I can, as I said, it has been a few years since I have used it.
