Using a True Bar

post #1 of 5
Thread Starter 

Long time lurking / first time posting.......

 

Started tuning our own gear this season and thoroughly enjoying it. My question involves the use of a true bar (or some reasonable facsimile).  If I slide this so called straight edge down the bases, checking for anomolies (convex, concave, etc.) will the results not be affected by the base edge bevels that the bar is riding down?  Am I looking for a uniform gap in that case, between the bar and the base?

 With a light/lamp behind the bar, you should see slits of light between the bar and the two edges (and you'll see the bevel angle too).  Ideally, you don't want to see any light between the bar and the base itself.

Depends on how thin the bar is or whether it's on edge or not (from the True Bar Wiki):

 

 

 

 

The base edges should down and out from the bases so the bar doesn't ride the edges unless the bases are concave:

Yep, good point, I always tip mine onto the corner when looking with a lamp.

Great visual, thanks! Other than "they came that way from the factory", what causes bases to become concave or convex?
