Makes you wonder how many basic repair skills have just vanished. Someone's grandpa knew how to fix that desk, now it's just... skilled work nobody does.
My old chair was wobbly last month and I almost threw it out. Watched a few youtube videos and fixed it with wood glue and clamps from the hardware store. It's still holding up great now. You're right @nancylee, that desk fix would have been common knowledge once. Sometimes you just have to try it yourself, the info is out there if you look.
