What can I use to hold an iron rod Torchiere lamp section to the pre-wired lower iron rod threaded bolt that won't tighten securely?
I solved this by using a pipe repair clamp from the plumbing department. It is meant to seal pinhole leaks in pipe. It looks like a 3-4&quot; long bracket that clamps to the pipe --not in this case the floor lamp tubing-- and has a rubber, inner liner. Get one in the 1&quot; or greater size. It has two parallel bolts that tighten to clamp it all together.
It's not the prettiest solution but it works. I salvaged a perfectly good floor lamp with bad threads this way.
