My first thoughts were machining a steel lathe dog on the MAHO, but the 3D printer provides a way faster solution, for a one off problem.

| RotarySMP:
Glad you are enjoying the series. I have attached the STL of the 20mm dog. The forum does not accept the extension .stl, so I renamed it to .txt, just save it and rename it back. The extra drive tab broke off when I used it. Mark |

Why don't you add a third leg between the base plate and the lathe bed to improve stiffness? |
| RotarySMP:
Thanks for watching the video. It would still need a stiff base plate. Making and fitting a third leg would be a lot of work. If I was going to do a lot more work on bed stiffness I would be more likely to bury it in a big block of epoxy granite. |
| nrml:
I was thinking on the lines of a simple block of steel or cast iron of suitable height bolted to the base plate and the gap between the bottom of the bed and the new leg filled with JB-weld or similar. A bit crude, but there will be some additional support to that thin span of bed without increasing the weight of the bed itself. Epoxy granite would be good but you might be venturing into the zone where the minilathe is compromising your design rather than being a convenient skeleton for re-fleshing. |
