or small bolt and wing nut.
For the bracket that goes up and down the pole, possibly something like
the arrangement on a TV aerial with a threaded U-bolt and a plate at the back.
For the articulated arm, a couple of pieces of narrow and thin
rectangular bracket is all you would need. Something along the lines of what
one use to find in a Mechano set. The two pieces of bracket could be
fastened together with a screw and wing nut so you can adjust the elbow to
move the dial up and down.
The first component with the bracket should provide for course adjustment in height
and the articulated arm should give you find adjustment.
Make sure to treat the indicator with care as it is a precision device.
Just allow the probe to touch the job gently and try and avoid the dial
being allowed to take a sudden very large deflection, both when making contact
with the job and when removing it.

Roger, Gary,
Gary has just described exactly the bracket typical of a dial indicator
when used on a lathe. You can buy this type of bracket with a magnetic
base. I have one. I will try to dig out a pic of it or a link to one
on the net. Edit: This is one:

You can even make a right angle transfer arm for doing what you describe.
These are used for fine measurements too close to a lathe
chuck which would normally foul with the dial indicator itself.
