My bit must have been too worn. I was giving thought to sharpening it using a grindstone.
Well, it just got worse. I got a new bit and drilled a 1/8 pilot hole. The guy at HD talked me into getting a screw extractor. Well, shit, the screw extractor snapped off the tip and is now lodged in my pilot hole!!
I guess I am going to have to drill 3 holes around the extractor bit in order to pull it out.
One of my friends was doing the same thing, and said that even after he got the flange bolts out, the metals had rusted together. Apparently this is a big problem with pool water pumps.
The back housing that I am trying to salvage sells for about $100. Almost wondering if it is worth trying.
Never thought that this would be as difficult.
