This is my first lathe and I am just a beginner and have been playing with
the lathe for a while. I found that when taking a facing cut on my mini
lathe (Chester Conquest) the cut is concave by about 0.07 mm in 20 mm. I
have read that facing cuts should be slightly concave but this seems
excessive to me. I am fairly sure that the head stock alignment is OK as it
turns reasonably parallel. I have searched the internet and although there
is plenty stuff on tuning lathes but not much on this problem. It seems to
me that problem is that the carriage is out of alignment and either the V
groove that runs on the bed or the dovetail for the cross slide could me
attacked but which one and how? I thought that I could mount the carriage
on the Conquest Mini Mill and run a dovetail cutter along the carriage but I
am worried that I f**k it up completely. Any thoughts anyone?
