Wait, isn't that final turn to get the bolt into its stretch range? Honestly, skipping it seems like you're just clamping with the bolt threads, not the bolt itself. That's a huge difference in clamping force.

Tell me about it. My margin for error is so small I can trip over a power cord and ruin my whole week's work. That 15% feels like the universe just deciding to play hardball.

Ugh, seeded eucalyptus at the beach is such a specific pain. It gets all limp and tangled in the wind, and those little pods end up in the sand. I usually point out how silver dollar eucalyptus holds up better, or even some local grasses that actually look coastal. Showing them a photo of the wilted mess from a past event can really help.

Check out @reed.ray's point, but stacking that many still needs decent alignment or you'll lose the edges.

Actually, that whole magnetic headlamp idea seems like a hassle waiting to happen. You're just asking to leave it stuck somewhere and forget it, or have it fall off at the worst time. A good old handheld light is simple and reliable, you always know where it is. Plus, now you have to remember to keep another thing charged up, which is just one more chore. Strapping something to your head for hours gets really uncomfortable too. Sometimes the basic tool is still the best one for the job.
