Thanks! I found some old “Liquid Wrench Powerful Penetrating Oil” in the toolbox. Looks like it has a spray nozzle. Do you think that would be good? I don’t mind buying a new oil, or even using something from the kitchen (coconut?) as long as it’s a good solution.
Thanks again!
Nope, I started to look as disassembling, but as another commented said, these are pretty different. That pin it turns out goes all the way through, and the holes on the bottom let me poke all the way through. That means the inside is hollow! Looks like I’ll avoid disassembling
