Just bought a new 9x40 mill/drill from Bolton Hardware to replace my old round column Grizzly. I never was happy with the base on the Grizzly. Wobbled too much when cranking on the table or headstock. Just set my new mill up on it's stand and have the same problem. I put adjustable feet in an effort to be sure things were level but now I am thinking that that was a mistake.. Seems the base flexes at the mounting point of the feet. On the Grizzly, the mounting points eventually failed because of this. So here's my question-what is the most reasonably simple way to support a 900# mill drill on cement. I would like to be able to move it in the future but I am starting to think that a pad of epoxy grout or cement is the only way that I will get things stable. I'm thinking a bolt through each mounting hole with a nut and washer top and bottom then a couple inches of grout/cement poured under the base. Then level with shims between the mill/drill and it's base? What does the collective wisdom of the group suggest? Thanks in advance!
