Thanks Tom for your suggestion “I place the base of the Veho scope on the WEPS clamp and put the scope right on the bevel.” That solved the problem for me.
I hold the base against the clamp with my right hand while using my left hand to GROSSLY focus and position the edge of the blade on the screen. Then I move my left hand to the mouse to be ready to click on the pull-down menu to take a photo. I discovered that I can do some fine focusing by lightly squeezing or releasing pressure on the scope base with my right hand. And when I’m satisfied, I click the photo. I don’t know if I explained this very well, but it’s working for me.
Now I’ve got to get a better light source set up from above – maybe a small goose-neck-type desk light.
