Building a Penelope v3 for not the first time. However I destroyed all my brain cells in my teens, 20, and ok a lot of my 30s. Anyway, can somone tell me if the long post (I guess it's the positive?) is supposed to have a normal screw top like the other which can be unscrewed from the post tube and perhaps mine is jammed. If so, I guess I have to go get wd40 or something. Tried hot water already....
