Just like MSC to not list the diameter of the post. My only purchase from MSC had incorrect dimensions listed, and they would not pay return freight. Done with them...
The Amazon unit is 1/4", which is not a size on Glenn's Noga base. Might be able to force it into the 6 mm (.236")hole, my guess is 'not likely'.
I am surprised that Noga does not make one.
Glenn, I usually use DTI indicators with my Noga base using the back dovetail mount. It gives a narrow "finger" sort of probe that gets into tight areas easily, and the indicator can be set up to read easily. I can well understand that as a beginner you do not want to purchase a bunch of tools, just an idea to consider for the future.
