OK cast, but the base plate could be an inch larger in diameter - the ram lands on the edge (see pic).There are some rack/pinion alignment issues - sometimes it drives down smooth, sometimes it jams. I tried to adjust the front bolts several ways, but cannot avoid.I did the "minus-two-teeth" upgrade to allow for handle adjustment at top of stroke (see pic).
