Tailstock alignment.

[tonyfoale]

Tony has a very rigid & compact assembly to hold the indicator. But just a word of caution if you were thinking to replicate the rotating indicator action with a typical mag stand. All bets are off as gravity can act on the extended arms & joints. The dial will read differently upright than inverted & depending on the extended arm, even laterally side to side.

Peter,

Thanks for pointing that out. I should have done that in my original post. I have always hated the typical methods for mounting gauges, it is rare to see any that come anywhere near being rigid enough. I have not watched the video yet but I need no convincing that those mounts are woefully inadequate despite their widespread use.

In the desire for rigidity I have even replaced the original clamping method with a welded on tab, as the pix show.
