had a visit from a mate today that was watching me check if my lathe was running true [centre to centre ] anyhows its a enco/grizzly 4003 an I was looking at the manual I have an it shows how to line up a centre point in the chuck [it recommended that I make my own dead centre for it so I did ] and to use the dead centre in my tailstock I put a piece of 40mm bar stock in a pre drilled both ends then mounted it in between the centres .I then ran the dial gauge along it an there was -002 runout which I got by adjusting the grub screws .
now heres my problem im unsure about
all the diagrams in book show top view only an no mention of side view which I found to be out -04
my mate said I have to get it back to close to zero or ill have a taper but to me id only have a taper if the cutting tool was on top
eg' my point is you will get a taer BUT it will depend where the cutting bit is
am I correct or totally wrong im unsure but my mate says even if the cutter is on the side ill still get a taper mmmmm im not that upto date like you fellas as ive said I only started working these machines in the last year or 2
thanks in advance for the answers
