Tin snips have definite limitations, then you graduate to the hacksaw,
fret saw and bandsaw. As your finances and inclination dictate you can
devolve to the cutting torch and plasma gun driven by CNC.
I had an Indian jeweler friend who could carry on a conversation, chew
gum, and cut the most intricate patterns with a fretsaw all at the same
time. Learn to use the hand tools, then appreciate the labor saving of
power tools.
