I'd expect most to get it trammed, tighten the bolts extra, and leave it alone.
Some companies doing Bridgeport or clone CNC builds made rigid rams without any
ability for the head to tilt or nod. A few went so far as to make even the head
custom, without any capability of having manual operation, sometimes as part of
the ram casting.
A simplified Bridgeport compatible head casting, without all the holes etc for
the manual operating parts, and the lumps and bumps that go with them, would be
a nice thing. Should cost less too, due to the simpler casting and much less
amount of machining. All it'd need is the back face for mounting to the
knuckle, the bore for the quill, the top for the drive to mount, and a slot for
whatever the machine builder wants to use to drive the quill up and down.
Putting that on one side, with cast in mounting bosses for the quill drive,
would be a slicker setup than what's always done stuck on the front.

Most of the Knee type mills have heads that can pivot up to 45 degrees left
and right. Bridgeports can also pitch forward and back. For those who have
done a CNC conversion on these machines, are those features every used anymore?
Or is the head trammed in as close as possible and then left there forever?
