I’ve got one that won’t budge. 36mm will grip, but has about 1/4 inch to turn and can’t get enough leverage to bust it loose. Spent a good 5 minutes with the chisel today. Soaked it in PB again, will try chisel again tomorrow.FYI. The easy way to remove the old globes is to take a hammer and sharp chisel to them. Just chisel them counter clockwise on the widest part of the globe and they will loosen up easily.
Even drilled a hole and jammed a screwdriver in there to try and crank for extra leverage. It’s just not budging yet.
