Bah, it was the wind. I have found that pin stock doesn't always match the advertised size, and I want to make sure I don't drill the scales too far of from that. I have drills in both Metric and SAE starting from 1/16" all the way up to 3/8", so whatever size they end up being, I programmed the holes in the blanks to .130", so as long as they are not ridiculously oversized then I should be able to use them.
I did get a huge pile of grinding belts delivered yesterday, though, and I will likely use most of them on these, in addition to the stash of 24 grit ceramics belts I have been hoarding just for these. Sparkling Smile is a total bear to grind. Didn't get started yesterday though because it was FedEx and errand day in town.
I tried to standardize to 1/4" pins a few years ago, but that seems to have been an idea of quite a few makers if I read knife supply inventories right. I would rather get these from actual knife supply places, but most of the time when I check the ones I am loyal too, they are out of stock of both 1/4" brass rods, and even more often 1/4" brass tubes.
But I am going to get back into the habit of buying the big three sizes, 1/4" (ish!) 3/16" (ish) and 1/8" (ish!), and work them into my designs going forward. Pin variation and placement has an art to it as well, that people appreciate.
