Hi all, I am having trouble leveling my lathe, it is a (Knuth Basic 180 Super). I get a .1mm taper over a 150mm cut. When I check it with a Dial Indicator on the top of the turned shaft it showed a .1mm difference. I put a ground bar in the chuck alone, and checked it and it also gave me a .1mm difference on the top of the shaft. When I put a dead center in the head stock and one in the tail stock the tail stock is lower than the head stock. The machine is a 2004 model but did not work very hard, I cannot see any wear on the bed. The lathe has 6 x adjusting screws at the bottom, 4 x at the head stock and 2 x at the end of the bed. The head stock is also adjustable on the y axis, but I suspect that the bed just might be twisted, but why the difference in high? Looks like the head stock is not parallel to the bed. Will it get better if I turn the 2 x adjusters out at the rear?
