Hi,

Just upgraded a mini lathe to a 4" 4 jaw chuck and now looking for an indicator to help in centering with potential for more uses.
After reading a lot of reviews and forum conversations I concluded that Brown & Sharpe is the way to go.
Using Amazon as a search engine I found a couple that look like they should serve the purpose:
Brown & Sharpe TESA 0141760652 Roch Dial Gauge Indicator, 0-30mm Range, 0.01mm Graduation, +/-0.003mm Accuracy
Brown & Sharpe TESA 0141760663 Dial Gauge Indicator, 0-50mm Range, 0.01mm Graduation, +/-0.003mm Accuracy
Do these make sense for my purpose? Would it be possible to use the 50mm one as a substitute for DRO on a mini lathe too?
As I understand, they come with no holding bars or bases. How difficult is it to make one myself? (I don't have a milling machine yet)
The 'white on white' dial notches are taking me a bit aback - would they be visible under work light?

Appreciate all expert advise you can share.
