I'm sure I used a Sugino spider with single pinch in the past.Think I had to grind down the top hat washer. Using a Tuff neck disc at the moment. But cant get to one of the bolts without moving the crank arm

Just looked through my bucket account and it was a one piece crank when I used the spider on my Robby.
