Re: Southbend 9" lathe table in CONCRETE?
A top limited to 3.5" will fail even with rebar. Your top should be at least 6" and would need a double matt of #4 rebar or else the top will sag and flex.toggle quoted messageShow quoted text
Youd also need corner bars with 18" tails to join the top and legs together on the end of each matt.
The legs should be 2/3 of the overall size of the top in width to provide sound bearing and support, though I would definitely recommend a rebar cage here also.
Sounds like overkill to ya? It's not.
Oh and you'll still have to shim/ level the machine.
Do bother placing your cast iron lathe on aluminum either.. they'll fuse together.
