Step 2: Top Board and Pod Loader piece
The two edges on the 9 1/2 inch side that get attached to the other board you will need to cut them both on a 45 degree angle.
The side that attaches to the long board, the hinge goes on the inside of the (2) 45 degree cuts. The side that attaches to the short board the hinge goes on the outside. You put the hinges this way so the whole thing will fold flat.
Attaching the Loader the top.
I took a sheet of scrap paper and placed it on the bottom of the pod load. I then took my finger and ran it over the edge of the lip where the pods slide against. Much like of you were doing a rubbing of a coin which crayon or chalk. You want the imprint of the edge of the lip on the paper so you can have a pretty close pattern to cut out. See pic. Cut the paper out following the edges of the imprint of the lip. Then trace that pattern on the front edge of the top board and cut that piece out. I used a scroll saw but you could use a coping saw or other fine bladed saw for this step.
Next you will need to bend the L shaped Brackets to hold the pod loader base to the top board. I put the bracket up to the base. Made a line where the top was. Then I put the bracket into the bench vice and bent the bracket down with my hand. I put a nice finishing bend on the bracket with a hammer. See Pics.
