Picked up one of these 8mm shank (.315") noga-style indicator arms for a certain project but happened to find it fit perfectly in my Brown and Sharpe indicator stand. It doesn't quite fit in my Starrett surface gauge base, since 8mm is slightly larger than the 5/16" masts that are meant to be used on surface gauges.

Anyway, thought I'd share since I've never seen it done before. Turned out to be super handy today but I'm going to have to remove the fine adjustment mechanism on the arm, there is too much play in the hinge for a tenths indicator. The one on the Brown and Sharpe base works great so I'll only use that from now on when using this arm.

Sure looks nifty with that metallic red.

You might want to give the arm a tune-up to improve the locking;

Thanks for the video, I've been meaning to take it apart and put some good grease in it. The stuff in it is pretty nasty!

I noticed a gentle pressure on the arm resulted in a tenth or so flex, but when I push on the fine adjustment (at the tip of the arm, right next to the indicator) it flexed over a thousandth. It's definitely in the fine adjust.

Hi,

Those fine adjusters are junk even on real Nogas. Never seen one that didn't allow some flex. I just run the adjuster screw in and leave it locked up.

It happens that I just got a Noga knock-off and I'm definitely going to do a tune up. Thanks for the video.
