Before I bumped any other old theads forward, I asked the elders if anyone minded...only got positive responses, so here's another good one. This is the one where we explored the idea of boring vertically in under the front of the hinge to increase the hinge's ability to flex and thus function longer...in another thread wiley p identified the technique as a swizwell, or some such. And the whizzy as well, though we all missed the significance of it 'til these several years later when sotc brought that up in a thread of it's own.
