With no formal training, I am sure I must be making hard work of this. I am
trying to set up a swivelling vertical slide on the cross slide of my super
7. Whilst the reference mark on the vertical swivelling surface is a clear,
and hardly marked
'|' , and is therefore no problem to set up, the mark on the horizontal
base plate is a badly worn 'V', which seems to have been scratched wider and
wider before I acquired it. I have had a few passes with the piece I am
trying to mill and am running out of spare metal!
It's easy enough to hold a pencil in the chuck, and align the vertical slide
by trial and error, and I guess it would be possible to gently bring the
face of the slide up against the face of a chuck with jaws removed in an
attempt to align it.
What I am wondering though, is there an easier or better method, especially
one which saves me from having to remove and replace my machine vice from
the vertical face plate each time I locate the vertical slide onto the cross
Any suggestions gratefully received.
Use a Dial Test Indicator attached to the bed to indicate off the back of the
machine vice (if in good condition) or the front of a parallel clamped in the
vice and pushed as far in as it will go. This will get you lined up for the
horizontal base plate. For the vertical base plate, use the DTI on the bottom
jaw if the vice or on the top of the parallel that you may still have clamped
in the vice. If you haven't yet got a DTI, get one and a magnetic base. They
are useful for all sorts of alignment jobs. about 40 quid from the likes of
A quick and dirty method I have used on my ML10 is to wind the
vertical slide down such that the lower end is below the level of the
surface of the cross-slide, then push the underside of the vertical
slide against the side of the cross-slide and tighten up. On my ML10,
this gives pretty accurate results very quickly. If I want it very
accurate, then the vice comes off and the vertical slide is held
against the lathe faceplate - could be quicker changing faceplate for
chuck then winding your jaws out, and then back in again :-).
