So these work with half inch chain enganging every second link?
I just got a little nostalgic looking at my old Woolloongabba digs 
I miss Bender !!
Did that laundry area ever flood or catch fire or anything else untoward?
It came close to flooding in 2011. That downstairs area served as a useful party spot and bicycle workshop for 3 years, but my most salient memory was that the trough on the left is where we used to bath our first girl.
