I do some hobby metal working as a complement to my woodworking and finally saved up to indulge in a bench top lathe. These machines are pretty capable, but lack somewhat in rigidity and mass. As I set about to design a bench for the lathe I came across some discussions on metal working forums about bolting smaller lathes very tightly to concrete tops to increase rigidity, dampen vibration and provide a stable platform to resist the effects of temp. and humidity changes. And as it turns out, it is actually very economical to do make.
Wood frame is Fir posts and stretchers and a pine 1×10 form. Lap joints assembled with glue and screws made for a speedy build….
Mixing Quickcrete isn’t exactly fun, but it isn’t so hard either. Floating the surface well is a skill acquired with lot’s of practice, which I don’t have.
So I wound up needing to do a skim coat with a product meant for prepping concrete floors for tile. This gave me a Smooth flat surface flush to the top of the form.
The top alone weighs over 320 lbs and the mill weighs about the same, with another 100 lbs of tooling on the bottom shelf. It shows no indications of going any where, but I’m going to attach it to the wall with ‘L’ brackets since it is so top heavy.
No chisel or hand plane work on this top :^o
Thanks for looking.
