I have apropriated an old belt-fed lathe, 40mm bore, aprox 36" centres. Legs and bed cast as one piece.
I need to raise it aprox 200mm (8") off concrete shed floor.
My questions are three:
1) Could I use end-grain (butcher block) sleepers to do this? - the advantage (to my mind) would be that the wood would absorb some vibration, however it may allow the bed to develop an harmonic at certain speeds/feeds?
2) I can concrete in H blocks and bolt it down to that, as I would if the floor was level and the correct height. - There's no real disadvantage to this that I can see
3) For levelling, would it be OK to use M14 bolts through the holes, with 3-4" washers underneath and level using the threads? An "adjustable feet" setup.
OR is it better to shim the entire length or the casting, and use bolts to clamp it down?
Bonus question: There's no manufacturers stamp in the casting that I've found, I will post pictures when I get to a PC, it has a brass? plaque with:
"W R
7 3 4 9"
Google doesn't turn up any information. I'm New Zealand based, and wonder if could have been made for "Wellington Railways" or something. Any help on ID is appreciated.
