- Provides a very quick way to indicate a part in a lathe.
- Can be used in both the X-axis and Z-axis directions.
-Provides <0.002" T.I.R.
- Black oxide coated 1/2"x1/2" tool shank
- R3 Bearing good to 43,000 RPM for long life.
1.) Mount stock in lathe only gripping lightly
2.) Start spindle at about 250RPM
3.) Slowly bring the Run-True torwards the desired surface to be indicated.
4.) As the Run-True makes contact with the surface of the part, it will start straightening the part in the chuck causing it to run true with the spindle of the lathe.
5.) Once the bearing is fully rotating, the part is then "indicated in"
6.) IMPORTANT!! Don't forget to tighten the chuck before making a cut.
That's all that's to it. If done properly, you should have less than 0.002" T.I.R. on the desired surface. See pictures below for
