Here's mine, I call her "Bertha". Built it myself with a little help from my Dad. 2 Hp w/ frequency drive. I went a bit overboard on the beefy side, probably could have used 2" square tubing instead of 4", but the thing is rock solid, and allows me to turn as small as pens, or swing a blank up to 32" diameter.
I'm working on a tailstock for it now. The riser block I fabbed up really works good, but the Delta tailstock is a bit weak for the bigger stuff.
