I wouldn't describe the Sherline as a "medium sized mill" which was
the original requirement - this is a small desktop machine.
Actually better off with the Taig in this size of machine IMHO -
slightly more capacity and altogether a more robust machine. Very easy
to CNC convert too.

Tony

Seig X series mills would be the most appropriate, I think. As well,
there is a solid knowledge base for doing exactly that.
The Taig/Peatol mill might suffice, but I suspect to be too small for
what you are looking for.
Search online for "seig X3" or "seig super X3".
Used. Look around for one of the RF25 or RF30 mill drills with the
round column.
Much maligned for the lack of indexing of the head to the column, they
are still a very useful tool, and have been available for quite a while,
at reasonable prices.
Cheers

Trevor,
Thanks for the suggestion.
The Sieg X3 looks exactly the size I was after. I looked at a few user
sites,
and from the detail photographs it does look a bit like something
of Machine
Mart quality. Not that this necessaritly makes it totally
unacceptable, but, are
there any British makes of that size or at least
something more comparable to my
ML7 in build quality? Obviously this
would be second hand. I have just bought an
old British Bench Drill to
replace my crappy NuTool item, and I promised myself
not to buy nasty
stuff in future.
Regards,
Garth.

There may well be, but likely, not one that is as well suited to a CNC
conversion. The X3 is doubly qualified, as you can order it as a ready
to convert model as well as a straight manual machine, IIRC.
They only qualify as nasty, if you start comparing them to industrial
equipment that is very much older, and cost very many times what these
cost now, when they were new.
Take a look at the mills on the lathes.co.uk site and you will see a
representation of milling machines of sizes suitable for a Model Engineer.
Most of them are not really good candidates for a CNC conversion.
Cheers

I would agree. The significant thing about the X3 is that it has a
divetail Z axis. Round column mills are a nightmare for CNC conversion
- generally the only workable solution is to drive the quill, which is
not as straightforward.
