HELP lol

I am trying to remove the interior tv antenna arm from my vintage Argosy and I cant get what I believe to be a set screw loose. Tried WD40 anything else short of trying to drill it out?

With stubborn screws/bolts, I’ve had good luck with a penetrating oil called Kroil Oil. Soak the set screw overnight. If it’s on the side, try soaking a piece of cotton ball and taping it. Also, some stubborn screws need to be tightened a fraction then counterclockwise to loosen. I guess you could drill it out then tap the hole with a larger tap of you wanted to reuse it. Good luck

Kroll does have a smell that is quite disagreeable to me. As well I never noted performance significantly better than the average penetrating oil. I just use wd40
