Craftsman 18V to PorterCable or BD Adapter

This is an adapter to allow me to use a Porter Cable 20v Li-Ion battery in my old Craftsman 18V NiCad drill. I am too cheap to throw away the old Craftsman drill even though the batteries no longer work and they would be too expensive to replace.
I ended up with several "slide on" Porter Cable Li-Ion batteries so I designed this adapter. It allows me to use the old Craftsman drill without modifying the drill itself.

You will need:
1. The printed adapter
2. One old Craftsman battery to sac
