Yep. Still trying to coax the staff from the mount. I've used the torch on less prominent and less visible hardware but have some reservation about using it on the bow light. Not knowing whether there are plastic components, potential to melt wire sheathing, etc. On the other hand, if I don't make progress, those are mute points.
I'll continue with the penetrating oil, tapping with the hammer, etc. for a bit longer and will add some heat. I'll also try the wrench.... gently at this point. Agreed on the neanderthal point.
I just removed my shafts and couplings. It humors me that I removed them with relative ease and I'm stuck on a project trying to replace a light bulb. LOL. I'll keep you posted on progress.
