I've been retire fore 6 years now. And while my brain would find the pursuit interesting I doubt my back, and feet are in agreement. And then there is the "benevolent" junkyard. My "go to" Pick Your Part is anything but a friendly place.
For YEARS I'd see people in there on the 50% off sale day dismounting tires and buying them by the stack load. So, I figured why not. You can break the bead with a scissor jack and tire irons will remove the tire. Anyway, the guy at the check out window had no issue selling me the tires. But the guy at the gate was irate that I had pulled the tires as it was no longer allowed. Mind you that there is NOTHING on their website nor posted at the yard that you can't remove tires. I've had other gate guys insist that certain parts were not included with a "Complete" engine and threaten to send me back in a lengthy line if I didn't give them money. So, yea, finding that benevolent yard is 50% of the equation.
Speaking of windshields. My son (home for a time because of Covid 19) stored much of his stuff in his second car (his grandmothers old car). One thing was a number of cans of Dust-Off that he uses while 3D printing. The sun struck a can just the right way and the heat expansion sent the can projecting through the windshield. We never found the actual can. The nozzle, trigger and a circular chunk (picture 3) that had blown out was about 20 feet away. If anyone knows how hard it it to not just crack, much less break a hole though a piece of laminated glass can understand that to remove a 2" piece completely is quite a force. So, this summer be careful where you place any aerosol cans!!!
