The first issue I'm working on is making a complete set of change gears. The first was a copy of the 60 tooth gear to compare with the original gear. Everything seems to mesh well. I plan on printing the complete set.
The original change gears are hardened and ground steel with a precision bore and keyways. The Compact 10 is a change gear lathe and every single thread you have to cut that doesn't involve the original gear train will have to rely on the change gears. It will be interesting to see how long those nylon gears last. On the other hand, at least you have them, right?
I picked up the same machine and I'm stuck in sort of an "analysis paralysis" on the bench construction. The machine came with a 30" x 72" steel top workbench, but no support to speak of below the steel top. The manual recommends a heavy flat bar mounting, with jack screws to adjust the bed. I'm toying with the idea of some angle iron below the steel surface, but also wondering if some plain old 2x6s would be enough.
Can you share how yours is supported, and how it's working out for you?
