While doing this, I've been testing the scoring jig and looking at how best to notch the natural key tops near the second score line. You can see in the photo below where Mr. Miller has notched to the second line.

The African Blackwood I'm using for the natural key tops is extremely hard. So hard, in fact, I feel like I'm notching a piece of stone. The key (pun intended) to success here, as Mr. Miller states in his eBook Most Excellent, is to take it slowly. And by "slowly," I mean a fraction of a millimeter at a time; otherwise, you stand the chance of driving the blade of the X-Acto knife completely through end of the wood. I'm not saying I've actually done this multiple times, I'm just saying it could happen...again and again and again.
I should have the final two coats on the sharps in the next couple of days. Then, it's touching up with the steel wool and knocking out the natural key tops. Easy peasy, right?
Until next time...
