The Creation Station at our SSCLibrary holds a light duty Fellowes Star 150 for anyone to use (with an initial training). We have a variety of combs (plastic binding bits), the biggest of which is designed for up to 120 page book drafts, reports, notebooks, calendars, etc. If you make a point of training to use this tool at our library, then you may reimburse us for the combs you use, or you may bring your own.
I find this machine pretty fascinating and useful. It’s like locking and unlocking your pages together with a deterring number of loops, not unlike Velcro. One line of wide Velcro down the spine of your report. As a tangent, you might find the vast assortment of Velcro products to be amusing–it’s not something I would normally tour though, but certainly a unique show of ingenuity: velcro.com.
Bonus: the bound books are simple enough to dismantle without a tool if/when the time combs to reduce/reuse/recycle the draft, report, etcetera.
