Wondering if we have any document binding equipment? I have a small printing paper samples project I want to do with the 5 art papers I use on the A1 printer and before I go buy something thought id ask 
@Clive has done a couple of bookbinding sessions, maybe they can help you out?
No spiral binder.
I always see paper samples with Chicago screws. these paired with a Japanese hole punch is great but understandably time consuming if you are making sample packs en masse.
Not quite en mass yet 
was wanting to do 10 ish but np Ill buy one. It could have been one of the things lurking and being unsused! 
I bought a new printer that can do A1 and that opened up a whole new range of paper for me that only come on a =>762mm roll…
