=================================================================

I have finished building my milling machine. I tried the foundry 
method but found it too much trouble and dangerous. It is more art 
than science and I am not a artist.

I build the mill from 1"x4" cold roll and purchased a milling table 
from Enco. It works ok but I could have built something better myself. 

I fitted the mill with a R-8 taper which I will have to buy more 
collets for as now I only have a 1/2" collect. Most of my endmills 
are 3/8". I am using a treadmill motor I purchased from the Surplus 
Center for the power and it works great.

I will post pictures in the dropbox as soon as I can take pictures 
that come out light enough. 

I have about 16" from spindle to table but I lose two inches for the 
tool and about three for the vise but that is still more than enough. 

Head doesn't tilt but I can move it up and down without having to 
relocate the part. I also don't have a quill. I used taper roller 
bearings for the spindle and a cog belt and pulleys for the drive.
The mill is mostly welded together and the table is bolted to a frame 
of 2"x2" tubing and at first and taking it slow. I was using a 1/2" 
endmill in steel and I took off about .020" at first and than increased 
it to about .050". I than switched to aluminum and took off  .080" 
without aproblem. The biggest problem that I did have was with the 
Enco milling table the screws for the gibs would loosen. I finally 
torqued the sh*t out of them and I think they will stay put. I started 
to buy one of the mini mills from Grizzly but heard that the plastic 
gears get striped easy so I designed my own of about the same size 
for less money.
