A helm, if you're skilled, can take possibly three hours to cut, another two to fold up, and two to three to glue. That's eight hours for a helm, at a generous timespan. We'll give you an hour per arm/leg piece, assuming it's low-detail. That's eight hours. And we're not even taking into account the shoulder pieces here.
Torso is going to take you three to four hours. Crotch, probably one or two. Handplates, probably 30mins each. Boots... an hour each.
That's one day completely gone, assuming you don't stop AT ALL. And we'll assume that you do at least the vitals: you take half an hour for breakfast, an hour for lunch, another for dinner, 30mins for a teatime snack, and 30mins total of toilet breaks. That's another three-and-a-half hours gone.
Assuming after THIS you take a very generous 30min break inbetween pieces to clear your table up for the next part, clean up, have a short break and a walk to prevent cramps. That's seven and a half hours gone.
So far you're clocking up 36 hours, given my quite strict timeslots. Low-detail stuff... yes, it's possible. But extremely physically demanding, and to be honest, nobody on this entire forum as the skill needed to pull this off with a decent suit.
