keeping DTIs perpendicular for runouot checks

[dsc]

Set up DTI with base and support block, etc, so plunger is horizontal.

That's the issue Neale, how do I know if plunger is horizontal? is it good enough to just set it by eye and assume it's horizontal? or is there some way to have it 100% horizontal, parallel to the surface on which the mag base is?

The other issue is that I have to points off which I can measure, one is a surface which is perpendicular to the shaft, the other surface is an unknown, it's definitely not perpendicular to the shaft as it's slightly off. If I measure off the first surface, all I need is the plunger to be parallel in relation to the surface, then it's perpendicular to the shaft. If I go with the second surface (much easier, more room), I need to set the plunger in relation to the shaft as I have no other point of reference.
