Here's something interesting. There's probably been hundreds of Shopsmith owners who tighten their machine in drill-press mode and notice that the Arm Lock Knob (part # 2) isn't dead-center over the "dimple" in the Base Arm (part #24). Then the folks on the forum explain the exact benefits of that design.

Here is a blog mentioning a similar technique on a high-end handplane:

Cool stuff! BTW I am expecting to receive a nice new block plane any day now. I'll keep the type secret until I get it.
