We have an outdoor lamppost that is controlled by a switch from inside. Originally the light was burnt out, so we replaced it, and it started working again, but it blew out the light again. So I'm trying to look at the socket to tighten up and/or replace it, but it's impossible to get at unless I undo a couple of screws at the interface between the post and the 'fixture'. They're all rusted and painted over, and I'm having limited success. Things I've tried with varying amounts of goodness:
- Naval Jelly rust dissolver
- A screw extractor bit
- metal drill bits to drill out the screw
None of them has really done the trick, but I'll keep trying. The fixture is probably stuck on the post as well - but it does appear to actually have a collar, so once I get these screws out I may have better luck with a mallet to dislodge it. Any other suggestions?
