In the process of inletting a lock mechanism, is it true that you may experience binding or "squeaking" even after it’s completely inletted?

The correct understanding regarding inletting a lock mechanism is that even after it seems fully inletted, binding or "squeaking" can indeed occur. This is because the surfaces of the lock mechanism may not be perfectly aligned with the inlet due to a variety of factors such as micro-level imperfections, variances in the wood, or slight misjudgments during the inletting process.

It's also possible for debris or wood fibers to cause interference, leading to binding. Additionally, humidity changes can affect the wood, causing it to swell or shrink, which might result in the lock not functioning smoothly even if it appears adequately inletted. This highlights the importance of meticulous fitting and test-fittings during installation, as any minor discrepancy can result in the lock not operating as intended, despite being fully seated in the wood.

Thus, the statement regarding experiencing binding or squeaking after inletting is indeed true, as it reflects the complexities involved in achieving a seamless fit for a lock mechanism.
