I suspect part of your problem is that you are using the wrong tool(s)
for
the job. Again, it would help to know what it is you're trying to
accomplish, rather than simply what you are doing. Are you trying to set
up
a part in a machine (e.g., centering a round part in a lathe chuck)? Or
are
you trying to take dimensional measurements?

In any case, if you are using the pressure from the indicator on the part
to
help support and stabilize your magnetic base, then that is one of your
problems.

Are you suggesting there are several types of magnetic bases
an I am using the wrong one?

No, I am suggesting that a magnetic base is not intended to be used as a
surface gage (which, apparently, is what you are trying to do).


When I am measuring the part I don't notice that the indicator
pressure is keeping it upright because it is in place and
also I have my hand on it.

Wrong tool and wrong technique.


As far as what I am attempting to accomplish I am obviously
verifying the part is flat on the table or checking differential
heights on the workpiece.

Perhaps obvious to you. But there was absolutely no hint of what you were
trying to accomplish in your first post, and your second post was ambiguous:
there were several possibilities based on the meager information you
provided. For example, you could have been trying to ensure that a part is
parallel to a milling table. In any case, you'll find that people are more
willing to take the time to assist you if you are willing to take the time
to provide more information (and are not snotty in your responses).
