G'day gavin Andy, Steve et al.
There is some good advice here, but! I don't have a mill and am not
seriously looking at present. What I have seen is that the micro
mills and mini mills are quite limited when it comes to drilling.
Larger diameter drills have morse taper shanks, also they are
generally. A micro/mini may not have enough Zaxis to allow large
drills and the drive may not have enough grunt.
Regarding lathe attachments, the standard attachment is a large
fraction of the price of a micro mill, as Andy says it does not seem
a wise investment. The exception may be the Taig attachment which
appears quite flexible (use wise) and better value for the money.
For me, if I had twice the money to invest and twice the space I
would have purchased a much larger lathe with a decent milling
attachment rather than two limited machines.
As an alternative an erzats milling attachment could be made with a
piece of steel or aluminium angle (not my comments on not using
Aluminum). Here is Oz you can get 80 x 80 x 6 Ali angle. A cheapy
drill press vice, the type with mounting slots along the sides, could
be fixed to the angle. Adjustment would not be easy but what can you
expect for AUD$30. (63mm drill vice AUD14 + AUD10 for Ali angle +
nuts and bolts = AUD30). There are other options which use the
compound slide to provide the Y axis adjustment (see Varmint Al's
site). Some of these options may be rough eg MS or Ali angle may not
be exactly 90deg. but if this is important we have files or a cutter
can be put in a 4 jaw chuck and a pass take over the surface.
Building an adaption of the Varmint Al approach is my next major
lathe project, in the mean time I have a cross drilling atachment
which needs the finishing touches.
Summary of my opinions, The micro & mini mills are limited but a
better investment than the purchased milling attachment.
One good turn deserves another.

Ian

A milling slide vice for lathe means you are limited by the lathe
speed.
You will not be able to mill with the smaller bits which will need
higher
speeds.

I've got one of those vertical slides. It's fittted by removing
the
topslide and fastening it down to the "swivel disk" in the cross-
slide. It
would have been better if it had T-slots to fasten jobs (or a
vise) to the
front of it, rather than that big, overhanging, "toolpost"
arrangement.
Check if your cross-slide will wind far enough over to make full
use of its
2.7" (approx) width. To adjust the depth of cut with a milling
cutter in
the chuck (or collet), the carriage handwheel isn't nearly precise
enough;
you will need a handwheel and graduated dial on the outboard end
of the
leadscrew. As I've previously remarked, I wish I'd put the money
into a
mini-mill fund.

A friend has one, he is happy doing basic work, but he said it can
only handle small cuts or he has a chatter problem.

Hi, I too have a Seig 7x12 and have been wondering about
milling too,
The smaller lathe has a milling attachment one can buy - but it
won't fit
the 7x12 (I believe). Does anyone know of one that will fit? I
do
have a DVD
from Chronos UK that shows a Taig/Peatol attachment (with a few
minor mods)
being able to fit the 7x10/12. Has anyone any experience of
doing
this? If
so, what's the max capacity for milling?
I'm sure many will say - buy the Seig X-1/2/3 but Taig/Peatol
also do a
standalone milling machine for approx ?550 (UK Pounds). Is this
better than
the equivalent mill from Seig?
Thanks
