I have been able to get in a 1/2 hour here and 1 hour there, so I made a little progress on my armor.
I decided to start on the knees and elbows because they have a defined shape and do not connect to any other pieces. I did not take any pictures of me trimming plastic or sanding the edges, since that is boring

, so here are the trimmed pieces.
Foam knees in the back and ABS knees up front.
Foam knees inserted into the ABS knees.

Foam elbows in the back and ABS elbows up front.

I have some final trimming and fitting, but that will wait till I get the other armor pieces put togther. Now that I have a feel for the thickness of the armor and how to work with this kit, I am going to move onto the torso pieces.
