It would be nice to have a book stretcher on occasion, though. Need to turn an octavo into a quarto? No problem! But was this really a book press, or a press intended for some other purpose? The 29 inch long cheeks are very, very thin in profile, and I imagine would deflect quite a bit even with just hand tightening.

One of the most common mistakes in sharpening is to allow your stone or film to glaze over. This significantly increases sharpening time, since the knife is not abraded by the grit, but is burnished against embedded steel. Not using enough lubricant is a common reason for this, as is not regularly cleaning your substrate. Depending on the size of the grit, either a microfiber rag or a white vinyl eraser works best.
My sharpening setup, above, consists of a bright swing arm lamp mounted directly above a cork faced workbench (PSA cork shelf liner), a microfiber rag, a large squeeze bottle of water, and the Peachey Sharpening System. I find it more comfortable to sharpen at a lower height, around 34 inches, than my regular bookbinding workbench. Many hundreds of knives have been sharpened here!
The microfiber rag is perfect for cleaning larger grit 3M micro-finishing film, from 80 to around 15 microns. This rag was white when I purchased it, a testament to how well it picks up and retains small metal particles. I also use it to clean off the knife between grits in order to examine the scratch patterns.
For 5 micron and smaller grits, a white vinyl eraser works wonders. Pictured above is the neon lime green 1 micron film, which glazes quite easily. Using the eraser on coarser grits eats it up too quickly.
Of course, over time, the abrasive will wear to the point nothing much happens, and you will need to replace it. I can usually sharpen ten knives or so on one piece of 2 x 11 inch film.
By using plenty of water as a lubricant, and cleaning the film after each use, the effective working life of finishing film will be prolonged.
Ndpreservation posted a nice synopsis of my lecture about the conservation of Dante’s 1477 La Commedia. It was an interesting and time consuming treatment, involving both resewing and rebinding in an alum tawed goat conservation binding.
This treatment provided impetus for further investigation into the history of conservation binding, both the term and the practice. I will present an updated version of this lecture on November 7, 2018, 10:00 am, Jones Room, Woodruff Library, Emory University, Atlanta, GA.
