Bulldog & ForgeBlink
Hey Bulldog, I’ve been working on a new lock mechanism that’s meant to be fail‑proof—every tooth is ground to exact tolerances. Got any experience with building something that can’t give up?
You want a lock that never gives up? Most folks go for a good design and test it hard. Tell me what you’ve done and I’ll tell you if it’s solid.
I started with a 12‑tooth gear set, each tooth measured to 0.001 mm, all in the same orientation. I milled the housing with a 5‑micron repeatability laser, then hand‑finished the contact surfaces to a mirror finish. After that I ran 200,000 cycles on a custom test rig—each cycle was a complete lock‑and‑unlock at 5 rpm. The only failure was a 0.02‑mm wobble in the cam that I immediately re‑machined to a tighter radius. I’m still tweaking the spring preload, but everything else holds steady. Is that good enough?
Sounds solid. Tight tolerances, good surface finish, heavy testing – that’s what it takes. Just keep an eye on temperature changes and dirt, those can bite even the best gear. If the spring’s holding and the wobble’s gone, you’re on the right track. Keep testing until you’re sure it won’t fail in the field.
Thanks, I’ll keep a log of temperature spikes and run the dust‑insertion test tomorrow. If the gear still sings without a hitch, I’ll let the lock stay in its own shrine.
Good plan. Keep the log tight, watch the temp and dust. If it still runs smooth, you’ve earned that shrine. I’ll be watching.
Will do. I’ll post the logs after each run. Expect only the most pristine data.
