Manual Peachey Board Slotting Machine

Board slotting is likely the strongest and least invasive method of treating detached boards. Detached boards are the most common point where bookbindings fail.  Christopher Clarkson developed the technique in the late 1970’s. The board slotting tab at the top of this page and the board slotting blog offers more information concerning its history, technique and recent advances.

The original Peachey Board Slotting Machine, developed in 2005, is used in conservation labs around the world. It is, however, a somewhat large and expensive machine, and best suited for large institutions. The Manual Peachey Board Slotting Machine is a new affordable alternative for individuals, regional centers, smaller institutional labs and even larger labs with space limitations. This smaller machine can be moved out of the way when not in use, freeing up valuable bench space. It is also simpler to operate.

The Manual Peachey Board Slotting Machine features stops that automatically guide the positioning of the blade when starting and stopping a cut. In order to make this machine more affordable, three aspects are limited as compared with the original machine: the maximum length that can be slotted is 15″ (rather than 17.75″), the board needs to be manually pulled or cranked using a hand wheel, and the angles for slotting are not infinitely adjustable, but can be set at 11, 13, and 15 degrees. These are the most common angles used. In fact, I use 13 degrees about 90% of the time, 11 for very thin boards, and 15 for thick ones.

This machine is less intimidating when compared to the original. The orientation makes it easier to sight the height of the blade. The carriage can be quickly pulled back into starting position after the end of a previous cut. This also makes partial (or biscut) slotting of a board very fast and easy. Overall, the slotting operation seems to be quicker. Many bookbinding and conservation students, such as those from North Bennett Street School, have been trained in the fundamentals of board slotting.  A one to three day workshop on machine operation, basic slotting technique and structures is recommended, though.

For Sale! Wide Round Knife With a Secondary Bevel

The cutting edge of this knife is slightly wider than the narrow Swiss and French knife that I currently make, but the length of the blade is wedge shaped so the area that is gripped is still comfortably narrow.  Also, it has a secondary bevel, which accounts for the strange looking, extremely acute 8 degree primary bevel.  The advantage of a secondary bevel is that there is much less metal to remove when resharpening or stropping. This is especially the case with a thick and wide knife like this. The primary bevel is fairly roughly ground: only half a millimeter of the secondary bevel, which is the cutting edge, is fully sharpened and polished. In a normal knife of this thickness, the length of the bevel would be about ten times this amount. Although I don’t think the time spent sharpening the bevel corresponds one to one, it does take significantly less time.

The drawback of a secondary bevel is that there is not really enough metal to feel it resting on your sharpening system, so this knife is recommended to those that have some experience in sharpening.  This wide cutting edge is useful for hogging off leather for edge paring and also used in a scraping manner for headcap and spine areas. The slight wedge shape on the leather handled knife, and the rounded thumb holds on the wood version provide excellent control.
