Have a friend drive down a smooth road with you on the passenger side. You open your car door, lean out and use the road as a grinding surface. Simple and foolproof.
Don’t hold the nut in your bare hands, the metal will get hot.
And make sure you are going at least 120mph.
:rolleyes:
Had to tell my tale of furniture booboos here. Back in 1962, just several years after marriage, we bought a really nice solid cherry dining room set from a St. Louis furniture store, IIRC Famous Barr. A piece of this was a dining room table, with two removable top leafs. This table was and is used quite a bit, with much installing and removing of the removable parts, depending on the number of folks expected.
And it has gone thru several moves, one from St. Louis to Bellevue, and another one of several miles within Bellevue.
Well, about a year ago we had just finished a Thanksgiving dinner with eight guests. Afterward, after all the dishes, etc., had been moved into the kitchen, my wife and I were tugging on the table to get it to move apart enough to remove the leafs, when one of the legs suddenly collapsed, dropping one corner of the table to the floor. Had this happened with the table loaded with the Thanksgiving feast a spectacular disaster would have ensued.
Inspection showed that, while the three intact legs were fastened with heavy bolts (and glue), the one that had collapsed was attached only with glue. The bolt holes had all been drilled, but the bolts had never been installed. So this table had lasted for almost fifty years with one leg held on only by glue.
Luckily the bolts were perfectly standard, and my local Ace Hardware was able to furnish these on the spot. So our beautiful cherry table is whole once again. My wife is still sort of shaken about what might have happened on countless occasions. I would have written a nasty letter to the manufacture, but likely all involved are probably dead.
