All MetalShaping - If only I had the time!

Hi I am Andy, I have always restored old cars as that is all I could afford. This was done using ready made panels where it showed and home made ones where it didn't. I would like to progress to being able to make my own panels for any repair that I am happy enough to put on show. I have bought a Nibbler Senior, ( like a Pullmax) and I am trying to learn how to use it to help shorten the time taken to make panels. I know some may not approve of machines but as my title suggests I never appear to have much time and if this helps me get panels made then it's got to be good. I also like turning and milling and I am learning CAD and hope to be able to build my own CNC machines. I also have a few old agricultural machines I keep running as best I can. Looking forward to learning from all you experienced guys. Thanks Andy.;)
