This garage door work is comparable to working on a vehicle suspension. Similar springs, similar preloading force, etc. And similar threat of death if you fuck up or do something stupid. Nothing wrong with doing things yourself, but make sure you're following basic safety standards and procedures. And don't do stupid hacks cause the actual tools are expensive. This is how you get injured or killed.
