The Czeck Edge Ruler Stop

I purchased the Czeck Edge ruler stop about two months ago and keep finding more and more uses for it. It costs around $35 and clamps onto almost any ruler easily and securely.

In addition to a ruler stop, it is accurate enough to convert a ruler into a double square. Although marketed to woodworkers, bookbinders will also find it quite useful. The non-rusting anodized aluminum is slightly more compatible with binders boards, leather, paper and cloth than a hardened steel Starrett double square.

This tool is useful in circumstances where your dividers are not large enough, for example when centering a label in the middle of a bookboard.  It can be used for measuring a book without relying on quantification for boxmaking: simply set the stop for the measurement of the book, then transfer the distance with a knife to your board. It could be used for laying out tooling. I’m sure there are many more uses.

The small (3.75 x 1 x .5 inch with the knob) size is appropriate for books. This is a handy little tool at a reasonable price. Czeck it out! Sorry!

Here I am using it to position the catch plates when mounting clasps.

The Battle of 1667 Physica Curiosa and the Book Conservation Fixture

Nice to see my Book Fixture getting a workout at the UCLA Library Conservation Center, battling all 1,389 pages of Gasper Schott’s 1667 Physica Curiosa. Typical of alum tawed books from this time, the spine is now very inflexible; note that the leaves start to drape about 2cm from the folds. These books are a bear trap, err, make that an elephant trap in this case.

Thanks to Chela Metzger, Library Conservator at UCLA, for initial impetus for the fixture.  And she is now Tweeting!

Improved Book Fixture

I’ve made two improvement to the in-situ book conservation fixture. First, the sliding arm is now machined out of a solid 1 x 1″ block of aluminum, so it much more rigid. The second is the front bar is now made from a 1″ rod of Delrin, much  more paper friendly than the previous aluminum one, and has a larger diameter. History and more images of an earlier version. Available for purchase here.
