My atlas 12 suffered from much vibration and a small motor that bogged down at a cut deeper than 10-15 thou. So I poured a 3 piece foundation mortaring them together with precision grout sold at HD. Adding up the 15 bags I added over 1000 lbs. At each step I was careful at squaring and leveling all parts. My method was to first pour 2 bases. When dry I leveled/shimmed and lined up in place and packed grout aroud shims. When shims were dry I removed and fill with more grout. Each piece was leveled 3 point. When base was dry and in place I set upper mould on base and poured that in place. After dry I flipped slab over, leveled/shimmed 3 point and again filled with grout. I drilled and epoxied all thread at 3 locations to secure lathe. Concrete always creeps while drying so I still had to level and shim lathe on base despite careful construction.

I then bought 2 hp dayton 1 phase motor from my local scrap yard for 19 bucks. What a deal. Mounted that on the wall behind lathe to isolate vibration.

Also bought wedge tool post from cdco which I really like. With these upgrades my lathe performs much better. I dont know what is normal for other lathes but I can take a 25 thou cut in annealed rod with a feed of .002 per rev at about 200 rpm, reducing diameter by .05 each pass. At more than .025 belt slips. Little vibration and no chatter so far.
