I am trying to measure the crossfeed position on a lathe, with the
indicator on top of the magnet and pointed in line with the magnet.

On one end of the MM is a 1/4-20 tapped hole. Mine has a thumbscrew on it with a
red plastic head. This engages the lug on the back of standard dial indicators.
It is simple to remove the 4 screws and rotate the lug on your indicator 90° if
your indicator isn't inline. Here's a pic:

So I think all you need is a lug-back indicator and you're in business.

That help?
