PM1236 lathe Compound Slide Dial.

Hey guys,

I have a new PM1236 in metric, with DRO.

I've also noticed the dials gradiations are off. I think the problem is the screw pitch not being precise. I'll recheck tonight how much the DRO shows for one full revolution (actully, I'll probably do 10 revolution for the sake of precision).
 
Thanks for letting members know about your difficulty. Please post, and let us know how you getting along.</SPAN>
 
Ok I checked my Y axis : over the course of 30 full dial rotation, I get a linear error of 0.035mm (0.0013") as per my DRO. Thats 0.07mm error in diameter.

Error in diameter is 0.002mm per 1 full dial turn. I don't worry about that as I'm relying on the DRO anyway.
