Oh man, that stinks! I had the exact same thing happen with a softbox that said it fit any speedring.

Anybody ever think about how the whole "right height" thing changes depending on your sharpening? I was chasing the same problem with my dovetails for years, thought it was my technique or the wood. Then I switched to a steeper bevel on my chisels and suddenly the same blade height worked perfectly. The factory bevels are usually too shallow for dovetail work, so your blade sits too high just to get through the cut. Might be worth trying a 30 degree instead of 25 if you havent already.

Doesn't it seem like the best way to learn anything is when someone ties it back to a tree, a map, or something you see every day?

Doesn't this sound a lot like how we figure out our own past by looking back at what we actually did?

Did you have to decode the treasure map or did the color coding actually make sense? I swear half the time I find "organized" wiring it's just someone's idea of organized, like my sock drawer. At least you didn't have to play "follow the mystery wire" through three walls like I did last week.
