FW folks: help is needed. I am the proud owner of an original penguin walking foot. Today, I decided to try to see about using it (I've been too intimidated to touch the thing since I saw how much they are worth ...mentioned to DH today they had gone up to $ 650-he said sell it, I said what are you crazy????, I'll never find another).
From info I found on line, and from holding the penguin up to the shaft, it looks like the thread cutter must come off. I tried pulling it down with my fingers and a screwdriver. It will turn around the shaft but is not moving down and I don't want to score the shaft too badly. Any suggestions? Thanks, I know one of you will have the perfect solution! :)
