The screw that clamps the upper blade guide unit on my bandsaw has an interesting problem: it's recessed in so far you might grab the identical screw that holds the blade guide itself.
So I made a 3" extension with a press fit bolt in one end and the original screw threads into the other end, where I will probably apply some locktite.

Now I'm less likely to throw off my blade guide adjustment by grabbing the wrong one.
