Projector Screen Tensioning

Does your manual projector screen not pull down easily? Will it not stay down after you jerk it downward a few times? If so, you might need to re-tension the spring in charge of maintaining the position of the screen! Today, I uninstall my screen, tear it down and re-tension the spring inside to make it work properly again. I'll show you my trial-and-error process so that you can attempt your own fix--before you trash your manual pull-down screen and buy a mechanized one! The crux of this process requires a unique tool, which can easily be made out of scrap angled metal (I used aluminum, but it could be iron or anything else strong and thin). Please leave your comments and questions below and I'll try to respond as quickly as possible!
