Smithy CNC

IF you are seeing this more then once--I'm sorry-- But I'm new and
will lear my way around

I currently have both a Sherline 5400 mill and Sherline 4400 lathe.
These have been converted to CNC by Backtrack CNC. I an trying to do
milling on Alum paintball gun bodies. this is basicly "engraving"
using a ball mill. I have tried different feed rates (slow to ultra
slow) faster speeds, light cuts, different mills, drowning it in
lube--in short everything I can think of and still get mill marks in
the cuts (whick will later be anodized and look like shit)

I've decided that the Sherline is just not ridgid enought to get good
results on this type of work (I can SEE the head delflecting at the
start of a cut)

At any rate- I'm thinking real hard of getting a Smithy. I've seen
the machies in person and they loog good to me--of course they weigh
about 10X as much as the Sherline too. I'm thinking of the Midus
with
the CNC conversion. Does anyone have any expericence or coments on
this? Thanks in advance
