AL960B level and alignment
G'day All,
I'm a new forum member and I'm also new to the hobby machinist world.
I apologise in advance. I know this threads been done to death and I have been reading some older threads. I'd feel better if I proceeded carefully with good advice from people with experience.
I bought my AL960B lathe early last year. I'm trying to set it up as perfectly as possible to cut parallel.
I've fitted some decent feet and using a 0.02mm/m precision level, I've levelled Across the ways and the saddle with very close results. Having done the 2 collar test over approximately 9", I'm getting a .006" difference. Larger at the tail stock end.
I tried adjusting the feet to twist the bed and bring the cutter closer at the tailstock collar, but the best I can get is a .0015 difference, larger at the t/s end. At that the R/H rear foot is being lifted off the ground.
I reset the bed level again and bought a 5M parallel test bar for the head stock spindle. Sweeping the bar with dial indicator proves that the spindle isnt parallel to the ways.
What would you guys recommend as the next step?
Any advice is really appreciated.
Thanks, Denis.
