Building myself a 12x16 storage building

I guess once the cut length and angles are the same, it will be pretty easy to duplicate 18 pieces and stay within specs

Finding a flat suitable surface so as not to grovel on the floor for assembly is the hard part of constructing them. If you can set up a miter saw with length stops you can blow right through the cutting pieces to proper angles and lengths. Tell Rock you have a project for him. He likes working with wood.

I wanted to but lifting the section was way too heavy by myself. I probably could’ve but didn’t want to hurt my back more than it already was.

Yeah, I hear you. If you can't get help lifting them and don't have equipment, building in place is all you can do.

I was thinking about making a jig from the first one on a sacrifice piece of osb or plywood.

You can build a jig on the floor. Place blocks around the first one for locating and tack them down with screws or long trim nails.

I’ve got enough scraps that I can use some screws to mount blocks.
see the attached. It shows the length and on the right it shows the angles to cut the ends

It’s not very complicated but back breaking at 61 with severe arthritis. I’m gonna get it done though, I would love to have it dried in tomorrow but that’s a wish. We're expecting some
Storms late in the day so I’m gonna try to start earlier than normal. Will be cooler as well

Assuming those are gussets at connections in the rafter drawing. You may want to use some structural adhesive in addition to screws or nailing. I actually used a heavy pneumatic wide-crown stapler (with adhesive) on last shed that I built and it worked out great.
