These are some great DIY tips! Reminds me a bit of AvE on YouTube when you called the bearings, "industrial lego." People.don't seen to realize that bearings, bolts, springs, and other bits and bobs are so standardized and universal.
And yes, there is little more frustrating than realizing an expensive purchase has one cheap component that seems value-engineered to fail. The solution is posts like this pointing out those failures to less-informed consumers.
Yeah AvE cracks me up. A good natured, foul mouthed technical dude with a healthy dose of irreverence for authority. I think I picked that ism up from his videos. I also remember Matt Farrah referring to the Fox Body Mustangs as auto sports Lego so that probably contributed.
I remember being a kid working on bicycles and noticing how standardized all of the components are. When I transitioned to cars I realized the opposite was true. I'm of the opinion that if the Big 3 hadn't been bailed out so many times and been subsidized by IP laws we probably would have ended up with a similar standardization of components eventually due to more players entering the market to fill the niches. I can only dream.
