Well, clearly we are pushing the limits of such a gauge, but you can do it - if there is enough negative bearing. Just look to see whether there is a gap under the middle point. You can even use it as a component bearing gauge by moving two points off the bridge and just putting one of the end points on top of the bridge - you can see the negative bearing a little better if you do it this way. You get creative when your good tools break (the foot of my Lowell gauge broke - gotta get another).
