For some reason I find it more of a challenge to reverse engineer or come up with an alternative to fix something than just buying the replacement parts that are needed. In the U S Air Force they had what was called ABDR. Aircraft Battle Damage Repair. It was basically shade tree mechanicing at its best, and you were graded on your ingenuity on making a repair out of nothing, just to get one more mission out of the aircraft if need be. This same principal is what keeps a lot of old and out of production stuff running years down the road. I find that making or coming up with an alternative, and still having a decent item in the end that don't look all that thrown together and still be functional is a challenge. Most anything can be fixed if you gather up enough ideas and ask enough of folks, and put the ideas to work.
