All those fancy machines do is speed the process up. In the right hands it is a quick way to perfection and in inexperienced hands a quick way to junk. At the Dutch Meet I have to thank Marty for showing me how to tip an edge with just a hammer, modified cold chisel and a block of wood since that is all I have to work with at home. When I was getting my aircraft mechanics licenses we were only allowed to twist safety wire by hand, no fancy twisting pliers. I had lots of cuts then callouses. Learn the time consuming way so when you can afford the fancy tools you appreciate them more. Slow and steady gives a better perspective on whats happening. Tony
