I'm down to only asian batteries for my old Dewalt 12v drills. Got three or four of those, still my favorite model, damn near 30 years old now........But those batteries- what a **** shoot that is. They're so cheap you can buy two hoping for one good one. I've swapped out the battery guts...
I use the Caswell Copy Cad setup. But infrequently enough I hafta re-educate myself on it whenever it's pulled out. Power supply is kind of complicated. I'm impressed by how long the plating looks nice.
So the one larry g shows gets pushed thru, the one you show gets pulled out then inserted in the other side. How old is a ratchet like that? I've seen them, but never had one.
^^^ The one I'm talking about doesn't look like that at all. BOTH ends look just like a typical 1/2" drive extension. I guess I'll have to buy it to get a picture.
