First up is a cutting guide with finger guard. It is about 3/4" wide and is ideal for trimming book cloth. This design is not ideal - the ones I remember had a built up section in the middle that made it easier to grab and hold on to. Still, this works pretty good and I may get around to fixing it. The upright end goes to the outside, facing away from the book to protect your fingers from the blade as you cut.
This is a punching cradle bought as a kit from a book binding/paper store. It is fairly simple and could easily be reproduced. (The kits are no longer available). The white section is tyvek, but could also be cardstock. Over time you have to glue additional tyvek or paper because lots of punching will weaken the join.
Finally, this is what was fondly called the corner-matic in the conservation lab. It is used to cut the corners of book cloth when making up the cover. I think the Banister book has instructions for something similar, but I much prefer this design. This pictures shows the corner-matic face up so you can see how it is put together. To use it, place it face down over the corner you want to trim and you will get a nice 45 degree cut the right distance from the board corner.
