About Club Builder Lab

Club Builder Lab is an independent English-language workshop for people who assemble, repair, and obsess over golf clubs. It is a visual bench with a first-moment physics engine: measure a club, model a build, simulate changes, match a set, print a sheet.

We do not maintain a global manufacturer spec database, we do not certify conforming clubs, and we do not recommend a shaft from a swing video. Data stays in your browser unless you export it.
