Thanks Val, In high school, our punches were huge floor versions, one was hydraulic and one had a large lever.
I miss the corner punch/nipper. And the sheet metal edge bender was fun to use.

With my infrequent creation process, I haven't run into too many items needing commercial shop work. Not since I worked next to a hydraulics repair shop.
My trusty tools include a plug-in hand-drill with various bits, and not even a keyless chuck, and metal files.
Since my late father was a hobbyist woodworker (TV repair/electronics, photography, etc...) I had access to a variety of tools at too young of an age:
I developed all kinds of bad and dangerous shop habits that have taken me years to ween myself from, such as stripping wire with my teeth, refusing to wear safety goggles, using the stove to melt things, and working over a soldering iron in an enclosed space inhaling the lead-oxide enriched fumes as if it was second-hand cigarette smoke... ahhhh.

Of course, I'm beyond a many of those shop-iniquities at this age... eh..
No scratch all that, I do use wire-strippers now, at least. ;-)

I know what you mean by missing tools. I loved having a large shop. I miss having a mill and a lathe. sometimes what should take a minute or two to make a part takes a lot longer setting up jigs to use hand tools to do the same thing. I too have some pretty terrible habits. I still have all my fingers so they can't be too bad.

Mike,

If you are making holes in sheet metal and don't have access to a press, a step drill is a really cheap alternative. I use mine a lot but watch your fingers!!
