evening All,
just a quick question about the pros and cons of a mill with a quill vs
ones with a fixed vertical head and moving knee. Obviously the quill is
more conveinant for drilling or plunging, but presumably the moving
knee is more accurate? The Knee is more 'solid' when milling, but do
you mill with the quill extended at all?

given Im not in a production enviroment, and that I have a drill press
for drilling most holes is there any major disadvantage to not having a
quill?

thanks

Dave

I suppose it is horses for courses.
I can't imagine having to work without either to be honest
You need the quill for co-ordinate drilling as you will loose all feel on
fine holes just using the knee.
Tapping under power needs the quill too.

As for milling with the quill extended? I avoid it as much as possible. As a
guide, perhaps extending the quill by 1/3 of max travel and always locking
it in whatever position when milling.
Depending on the design of the machine, rigidity may be maintained at
greater extensions.
Some test cuts in steel will tell all about the relative rigidity of the
machine.
