Snagged another Makita 9.6 v drill with battery. Tested it when I got home - ran fine. battery looks NOS and took a charge, so good there. Drill chuck is screwed up, and someone stripped the retaining screw inside, so we'll give cutting it off a try to remove it. If I can get the chuck off I have a spare I can pop on. So will have another working drill. If not, I've got all those spare parts. I'm invested in the 9.6v line.
Needs cleaning, too. Lots of pipe dope and paint globs on it.
