Chuck'd Asunder
Pictured, the three-jaw chuck I mentioned in last night's post, disassembled as far as I can at this juncture: I haven't figured out access to the inside of the body of the thing, even though I've removed the obvious fixings in the form of the three, smaller machine screws seen here. I suspect that it will crack open at the back within the slight annular depression at the rear of the body. The tapped holes that would normally attach the chuck to the lathe's backplate lie in the outer, raised rim, so I think that I'm quite safe in this assumption. Everything needs a good clean, but considering it's probably sixty-plus years since the internals of this thing were exposed, it's in pretty damned good shape. A good soak in some solvent followed by an application of light oil should see it OK. The mating surfaces of the jaws look in pretty good condition too, so despite one of them [number 1 jaw] having lost a small chunk of its outer edge, it should work fine when reassembled. Still want to figure out how to get into the body of the thing, though: keep you posted...
It's probably screwwed together Kel: LARGE Stilsons (I have some) Although it has survived with just ordinary lubricants STP is SO MUCH better (I have some)!! And thanks again for the hammers. You'll be glad to know that I haven't used the ball-pein YET!!
