The real challenge here, I suppose, is that our OP has not been terribly specific in what kind of "
metal work" he would like to begin puttering around with.
My replies are based on
my perspective; I was a journeyman sheet metal worker, and I had daily access to brakes, shears, rolls, edge formers, welders, lock formers, uni-shears, double-cuts, Beverly shears, angle ironworkers, cutoff saws, etc, etc. Today, as a hobbyist, once in a while I want to make a metal box, bracket, install some rivets, or etc, and I miss having those big old industrial tools available to me. So my "must-have" list includes serious sheet metal tools. But to OTHER guys;
their perspective of "
metal work" might be as a body man who wants to putter around trying to make his own patches for a quarter panel which is not available any more, or even a new floor pan section for his 56 Studebaker. On the other hand, to my brother-in-law, "
metal work" requires a bridge port and a good lathe. And then, aircraft people
must be able to work with aluminum. This sometimes requires some different tools and equipment.
These disparate "
metal work" perspectives and related equipment needs could go on and on and on...
This post is not a critcism of the OP; rather it is my opinion of why our answers seem so different from each other...we just all have different perspectives. The OP
might be just wanting to be able to bend a piece of flat 1/8" X 1" steel stock into a bracket shape and then weld it, which would require as little as a good vise, hack saw, and welder. Or he might be wanting to learn to fashion his own body panels, etc. Different metal jobs require vastly different tools and equipment.
To the OP: I loved my years as a metal worker, and am very proud of whatever metal-working skills I may retain. You will likely enjoy it too. Let us know a bit more about specifically what you're planning to do in the near future with metal, and our answers will probably be more in synch with each other.
Good luck with learning metal work; whichever kind you choose!
