Your not turning steel blocks
my estimate is 50ibs for a circle of poplar(20% moisture content air dried and 31lbs a cubic foot) 30 inches in diameter and 4 inches thick and a total volume of 1.635 cubic feet, 6 inches would be 75lbs, 8 inches 100lbs...... and thats the high end... the block of wood itself would act as flywheel when turning, so the only thing you'd have to do in keep it turning at a suitable speed, it might be an idea to look up George Lailey a "green wood" turner and his techniques....Article on Pole Lathes and wood turning:

"And the four bare walls stand on the seashore. a wreck a skeleton a monument of that instability and vicissitude to which all things human are subject. Not a dwelling within sight, and the farm labourer, and curious traveller, are the only persons that ever visit the scene where once so many thousands were congregated." T.Lewin 1867
