Tom, my advice is to make the tool and not use the other blank. I worked hard to take an f/3.5 up to an f/10. Lots of flatening required. In your case (question asked) you will take a convex curve, unstable in grinding, back to flat and on again to concave. Whew, it seems like more work than making a tool. Besides, if you don't use the second blank give it to your wife and she can make one with you and when you are both want to get a larger scope you can make them into bino's.
