How I Built a Steam Box to Bend Wood (Without Losing My Mind)

Steam bending is a process that uses heat and moisture to make wood pliable. When wood is exposed to steam, typically at around 212°F, the heat softens the lignin, which is the natural glue that holds wood fibers together. Once the lignin is softened, the wood can be carefully bent into curved shapes without cracking or breaking.
This project kicked off with a pretty straightforward goal: build a box that could reliably steam wood blanks for bending. I wanted something simple, solid, and reusable. I also wanted to avoid overbuilding it because, well, it’s literally a hot wooden box.
