Here's another one. This place I'm renting was built in 1971 and nothing has ever been repaired in it. If it works it's because I got it back in working condition again. Anyway, the rollers/wheels/whatever you call them on the bottom of the sliding patio door were worn out and didn't spin on the metal track at the bottom of the door. So, the landlord looks at it, goes to the hardware store, comes back and tells me the wheels for the door are no longer made. I get online and find a place that sells replacement parts for sliding doors, windows, screens and all that kind of stuff and think to myself that they have the part. It's just a matter of figuring out which one it is. So, I take the sliding door out of the track to look at the wheels. I need about six dimension to figure out which one will work. I had to take the wheels out of the frame so I could measure it. I look at the bottom of the door to figure out who the frame comes apart, which was two screws holding a piece of what looked like aluminium at the bottom and the bottom. I had the door laying on two saw horses. After removing the screws and sliding the bottom piece off I noticed it was much heavier than aluminium should be. As I'm looking at the wheels to figure out how they come out of the bottom piece I notice the two vertical portions of the frame open up and slide away from the glass from my peripheral vision. This, in addition to removing the heavier bottom piece cause an uneven distribution of weight. As the bottom of the glass slowly starts to rise up I reach over to stop it, except the saw horse opposite my end of the glass starts to tilt because it was made of lightweight plastic. At this point I just figured to quit while I'm ahead because I wanted to avoid getting injured from the glass if it were to suddenly move my way. The saw horse tipped over and the glass slid back and the top part of the frame put a nasty gash in the drywall. It wasn't over yet. The glass then slid in a sideways circular motion toward the same wall, but this time without any part of the frame to protect it. Another gash at impact, but the glass didn't break. One side of the glass was leaning on the saw horse which started to slide on the carpet, which meant it was going to slide out from under the glass. The glass then lands flat on the carpet, but didn't break because the air between the glass and carpet cushioned the fall. All this and no broken glass. I found the correct parts, got it all back together and had the landlord reimburse me.
I guess the lesson learned from this is to avoid cheap plastic sawhorses.
