Attaching the precision leveling plate drawings for the SIEG SC4 footprint, in case someone else fancy giving his/her mini lathe a grinding overhaul. You'll obviously need a way to level this accurately and keep track of where it goes with time. The four leveling corners requires 0.5mm pitch thread (ball-end setscrews) for fine level-adjustment. Lastly I had mine precision ground but that's not a mandatory requirement, surface milling is sufficient.

30mm thick steel (27'ish kg), this ain't going anywhere. Farewell silly cheap and destructive wood bench.

All the best everyone.
