Screen Printing Press Set Up

I've been getting some inquires as to my screen printing set-up. It's a cobbled together simple set-up. The whole thing is mounted to a chunk of 1/2" scrap ply wood (for portability) and made to use 20"x24" screens. The "platform" was made to take t-shirts as well as small posters. The "platform" is mounted to the base on 2x4's and is 1/2" thick cabinet grade piece of wood.  There is a shoe lace clamped to the side that goes through a eye hook and a 20 oz. Plumb hammer through a loop on the other end as a counter weight. I haven't done anything with registration; so I'm not sure how effective it is at multi-color projects.
