Dial Indicator Rod
On the right side of the head of my manual knee mill there is a rod
that sets in clamp in the casting. A simple thumb screw holds it at
whatever height you set it. Its pretty short. In fact its kind of
in the way. If it was any longer I would have already removed it and
tossed it in a tool box.
I'm not really sure what its good for. Not really suitable for a
tapping head arm if you use the quill. I can't imagine tapping with
the knee. Maybe it might be okay with a coaxial indicator, but that
seems a bit of overkill to build a stop rod into the machine. I'm
also not sure it would reach down far enough to engage the arm on my
coaxial indicator.
Generally I think its an "anything you can use it for" feature at best.
I made a bar to act as a guide for letter and number punches and the
main support rod is held in a collet in the spindle but another
smaller rod goes into that hole to align it with the axis and stop it
rotating.
That's a clever use.
I've also seen it used for holding chuck guards.
Now that seems to be an obvious use now that somebody said it. I keep telling myself I'm going to make some mag base spray shields, but
bending a piece of polycarbonate and clamping it to that rod might be
really useful for keeping chips and coolant out of my face.
I made a couple of mag base safety shields some years back and put them
between the operation and me if I have any concern. Just about 12"x12"
square polycarbonate and flat, the mag bases are cheap these days and
sit out of the way on the back of the BP when not in use, handy having a
mag base as they'll stick anywhere there's iron.
