Looking for an adjustable internal pipe wrench.
Hello! I read Darryl1953's excellent post about a broken off pipe, and have one further complication. My pipe is a 1/2" size, and about 1/2" of it broke off inside the pipe that is in the wall. I tried a 1/2" internal pipe wrench, first spraying with Silicone lubricant, but from the efforts so far, I think the pipe has been ground away a little and the 1/2" internal wrench isn't grabbing any more.
Any idea where I can find an adjustable internal pipe wrench like the one Darryl1953 shows in the picture? So far, I've had no luck on line. Or, maybe I could wrap something rough around the outside of the 1/2" to make it slightly larger, yet still have traction or "grab" in that pipe. I'd like to find one that expands to 5/8 or so. I have a 3/4 and that won't work--too big.
Thanks very much!
