over torqued always rounds the small ones .and or inexpensive Allen keysThings have been crazy/busy around here this past week. My wife organized a "Walk for Parkinsons" charity walk on Saturday. Weather was great, over 100 folks showed up and she raised over $32,000 for Parkinsons research. I've been working on a robotic work station for one of the big 3 automakers and this morning they changed everything that I've done in the past two weeks, but I still get paid for what I've done. Today I made a new piston for the cylinder which was leaking pressure into the crankcase, because I couldn't stop it leaking past the rings. I think the previous piston had it's bottom ring too close to the wrist pin hole. Tomorrow I will pressure test that cylinder again, and hopefully the leak is fixed. I also learned the nasty truth about socket head capscrews today.---I love the look of them, but after you've tightened and loosened them about 5 times, the socket rounds off and then they can't be tightened any more, and even worse, the tight ones can't be loosened. Of course, I'm always an optimist, thinking they will only have to be tightened once.---HAH!!!
