Greetings, Anybody ever disassembled (and successfully reassembled) one of these? Google groups showed nothing apropos.
Just got a pre-Stanley North Bros 30A Yankee screwdriver off ebay. Not surprisingly the right-hand ratchet pawl is worn. Works ok as is, just have to hold the tip of the chuck on the return stroke. The guts appear to be held together by a split-slot nut which surrounds the shaft. There is a third notch on the outer circumference of the nut. I figure there's a special tool to wring it off. I tapped a bit with a tiny cold chisel, but it didn't budge. (Metal innards have been soaked, brushed and/or wiped with carburetor cleaner, penetrating oil, WD-40, and 3-in-1.) I left the wood handle and the exterior finish alone, BTW.
I successfully rebuilt the ratchet on my Defiance brace, so this shouldn't be too much of a challenge. Stanley even carries parts, in case I drop something in the sawdust. Just wanted to garner advice before I reach for a bigger hammer.
