When my brother-in-law used to work as a steel fabriactor, I used to sometimes visit the factory. I noticed they used some sort of hydraulic guillotine to cut sheet metal of various thickness. Maybe there's a similar buisiness near you, that could do it. I'm not sure how much metal is lost during cutting though.
Best regards.

I still don't know the difference between a nibbler and shears. Which one wastes the least amount of metal?

Hi PL,

28-Guage that’s 0.0149”
I have installed many windows and used that same stuff for capping.
All I use is a straight edge and a razor knife.

Clamp your straight edge into position, score the metal a few times with your knife, remove the straight edge, fold your metal and it should separate very easily.
Perfect cut every time.

The function of science is to make observations and measurements and to find correlations between the observed facts.

Take it to a sheet metal shop get them to cut it with a shear.

Seems the best way to me,  and something a workshop could do in 15 mins well , rather than you spending a whole saturday doing it getting blunt snips and sore hands
