Craftsman 18V to PorterCable or BD Adapter

thingiverse

This is an adapter to let me utilize a Porter Cable 20v Li-Ion battery in my old Craftsman 18V NiCad drill. I'm too thrifty to discard the old Craftsman drill even though the batteries no longer function and they would be too costly to replace. I ended up with several "slide on" Porter Cable Li-Ion batteries so I came up with this adapter. It lets me use the old Craftsman drill without modifying the drill itself. You will need: 1. The printed adapter 2. One old Craftsman battery to give up for the contacts A. Contacts B. Top plastic shell C. Screws D. Retention Clips (locking/release tabs) 3. Two springs approximately 3/4" long 4. Two bolts of your choice approximately 1.25" maybe 10-24 thread or 1/4-20 5. Two short pieces of insulated wire 6. Two pieces of metal for flat contacts. I use Hillman 1/2" stock, 0.016" thick UPDATE: v15 has a slightly larger and deeper hole for the retention spring.
