I keep getting a "page not found" for the link. I've tried putting plier handles, a screwdriver, etc in there. The plier handles won't fit in those bitty holes, and I can't hold it still with the screwdriver at all. I can't think of anything else with small prongs that would fit in there. lol
I think maybe I need to let it alone till tomorrow when I have more energy.
ETA: Okay now the link is coming up. Now I see the plumber's putty is not the problem, it's the gasket thingy right under the basin. Thanks for the info.
My tail piece doesnt have a nut to tighten it, you can see the little indentations in the photo about 3" down where I assume you're supposed to grip it, but my pipe wrench won't grip that.
