So I'm assembling my new Powermatic PM2800B Drill Press and I notice that the cast iron base is about as flat as table at a diner. It will rock back and forth from one corner to another. Has anybody else had this problem with theirs and will it go away once I put the head on it?

At the base, it rocks about 1/16"-3/32", but at the top of the column, this equals out to about 1/2"-3/4".

I wasn't planning on mounting it to the floor right away and the manual says not to use a mobile base. Should I just not worry about the "suggestion" and mount it to the oversized base that I made for my previous Delta 18-900L that I previously had and returned or contact Powermatic first thing tomorrow and see what they say? I plan on calling PM, but wanted to see if anybody else had this problem or if it's something I shouldn't even be worried about, put the head on it and start making holes
