A simple plank replacement turned into a two day puzzle

Had a job last month where a homeowner wanted a single damaged laminate plank swapped out in the middle of their living room. Should have been an hour, tops. The locking system was an older style I hadn't seen in years, and the new plank just would not click in without lifting the boards around it. Ended up having to carefully unclick and lift a whole section of the floor back to the wall, which took about 5 hours. The next day I had to go back and re-lay that entire quarter of the room. Ever run into a locking mechanism that just refuses to play nice with a single replacement?

Ugh, those old locking systems are the worst! Did the new plank feel like it was the right size, or was it just the angle that was fighting you?

Yeah the angle is always the killer with those old locks, @jade517. I mean, the new piece can be cut perfect but if you don't get that exact tilt when it goes in, it just binds up. I had to sand down one edge just a tiny bit, like barely anything, and then it slid right in. Maybe it's just me but sometimes the old groove is worn in a weird way the new wood doesn't match.

Right, but here's the thing nobody's talking about - the grain direction on the old wood might have shifted over time from humidity changes. I had a similar fight with a 1920s window frame last year, and it turned out the whole piece had twisted just a hair from seasonal swelling. So even if you cut the new piece perfect, the old lock's resting spot has literally moved since it was installed. Did you check if your old groove has a slight warp when you hold a straight edge to it?

You said it, those old locking systems are the worst. It's like how anything made now just doesn't fit right with old stuff, even when the specs say it should. Makes you wonder if they build things to last anymore.

The grain direction thing is real, but here's something else I've noticed with old lock systems (and I've messed with way too many of these). Sometimes the actual wood around the lock has compressed from decades of the latch hitting it, so the hole isn't even round anymore. I had a door from 1910 where the strike plate hole was almost oval shaped from wear. You can cut the new piece perfect and the lock body still won't seat right because the wood has literally been crushed down over time. Might be worth checking with a caliper if the old hole is still the same size all the way around.
