Test Indicator???

I have been using a .0005" Test indicator for the 6 years since I started machining and haven't needed anything more until recently (going to pick up a .0001"). I would highly recommend getting a "Swiss Type" one with the extended travel range (see http://www.fowlerprecision.com/Products/Test-Indicators/38mm-X-TEST-Test-Indicator-52-562-008.html) I have the inch version, but the extra tiny dial keeps track of how many times you've gone around. I own two other .0005" indicators and I wont touch them unless this one is on a setup.

Check out this site, they have awesome prices and good service: http://www.jtsmach.com/store-1/

If you can spare a little more, this is my exact model at a great price: 52-562-001

and the .0001" I will be picking up shortly: 1-818-215GA
 
Nobody has mentioned that you can interpolate between divisions on a 0.001" dial gauge to guess quarters, halves and three quarters just looking at the thickness of the needle.
 
When I wanted a good DTI, I got a .0005 Swiss Tasatast . When I check on the surface plate, it's one I use. The tool, in this case dial indicator or dial test indicator , for the job.
 
All new BestTest indicators are now assembled in China. Only the movement is Swiss made now. The new models do not have Swiss Made anywhere. Not even the case. Good indicator though. Very responsive.
 
I have and have needed .0001 indicators and .00005 indicators . In 41 years of machining , I can think of just a few jobs in which I really needed them . Working on the Deckel jig grinders and jig mills comes to mind when true position was .0001 TIR . I now use a Last Word or a Best test , what ever is on top of the heap . I don't build high precision machinery or work for DOD anymore . I would surely think a .0005 best test would be adequate for most anyone's needs , especially hobbyists . But hey , a Geo gets you around but they still sell Corvettes . :)
