It took about an hour, but I am finally done, trammed it with a dial
indicator. 0.001" over about 4 inches. (diameter of the circle that
the indicator makes when attached to spindle).

Only .001?

Why did you bother? Thats pretty far out.

Mine is trammed at .0003 at 8" and its Almost ok

You should let Iggy know getting it this close is ten times the work
of getting within .001 over 4 inches.

I fiddled with my Large Super Max till it was --O--O-- (that's an
arrow through two balls, or "dead nuts", an official engineering term)
and then drilled and installed a taper pin to keep it there.

I will try using the mill, trammed as it is. This is a "many times"
improvement over what I had when it was untrammed.

Are you sweeping a tiltable head to zero, Ig? When I hear the term
"Tramming", I think zeroing the table to the head.

(Just clarifying my newbieness, too. What's the terminology, guys? It
wasn't covered in Briney's _The Home Machinist's Handbook_)

It's not a tiltable head as in a normal use axis like a regular
Bridgeport. It's a CNC with a fixed head, but that still needs to be
fine tuned to ensure its square to the table and as Iggy noted, it has
some eccentric cams in the head mount to allow that small amount of
adjustment.


And if its off, front to back...it may need some shims. Which is not all
that uncommon.
