I mean - after you broke one... didn't a clue rake at least try to hit you over the head about the rest of them? Not to jump on the jump-on-Jay bandwagon (he's got enough trouble with his broken bolts already), but wasn't he the guy who asked what the difference is between foot pounds and inch pounds a while back? Yes. Excellent question. However, I also agree with Frogwatch. You just have to develop a feel for how much force things are able to take, and where the gotchas are hiding. Try telling a 17 year old "With some screws, you want to gently turn them in backwards until you feel or hear a click, or you'll strip the threads". Mine said "Well, how do you know which screws?" I really couldn't tell him, except to say that the higher the price of the thing you're trying to fix, the more likely it is that you'll have a problem. :-) True story. In high school autoshop, yes we used to have those, the grounds keepers for the sports field had their tractor in and were replacing a muffler. The gardener asked how tight to make the nuts. Someone in the class yelled out, "run it down until you hear a crack and then back of a 1/2 turn.". Everybody in the shop heard the crack as the U clamp broke. Class went in to hysterics. Now *that* was funny!! |
