honeycomb slide


Not So ‘Strange’ After All

Like many people, I saw the new Doctor Strange movie in theaters this weekend. I expected a fun, visually exciting film (which I got); but I wasn’t expecting a lot of library screen time, so needless to say, I was pleasantly surprised! Without spoiling anything, the library is the scene of some important plot developments, and features some very interesting set pieces, including books chained to a honeycomb-like sliding rack alongside the more traditional bookshelves.

While the sliding rack may not have been recognizable to librarians of old, the practice of chaining books certainly was. From the Middle Ages to the late 17th century, books were expensive and precious objects that weren’t allowed to be removed from the library willy-nilly. However, due to both their value as objects and as containers of knowledge, books were under a very real threat of being borrowed for reference and never returned. Initially, books were kept in large locking chests for security, but as libraries began to expand, the chests no longer provided enough room for storage and the books had to be moved onto open shelves. And so, much like dogs kept on a leash to prevent them from running off, the books were chained to the shelves.

It is unclear exactly when and where the first books were chained, but the practice caught on all over Europe.The chains were linked to a metal rod that ran the length of the shelf, which meant that in order to reference the books, readers were literally “chained” to the spot! To remedy this, desk areas were often placed in front of the chained shelves, such as these in the chained library of Hereford Cathedral.

There are some lovely examples of chained libraries that survive today, such as that of Hereford and a smaller one in Chetham’s Library in Manchester. If you get a chance, pay one a visit! It’s amazing to see a snapshot of what a medieval reader would’ve been faced with when entering a library. However, if you can’t make it to Europe, at least you can get a peek of the concept and feeling in Doctor Strange!


@coffeeandspentbrass I figured you’d appreciate this post…

Differences between KKM and Barsto barrels have been observed in my shop. Barsto barrels provide more accuracy and appear to be a higher quality product. I’ve been using a KKM barrel in the glock 17 I’ve been carrying, until I decide I’m happy with the gun as my new EDC.

I’ve pretty much decided to switch from the 19 to the 17 because my hands are a little too big for the 19. I like the longer sight radius and increased magazine capacity of the 17 as well.

I’ll be milling my signature honeycomb pattern into the slide to reduce weight and increase slide speed. After that I’ll properly tune the recoil system for the loads I’m shooting

The Barsto barrel pictured here will be fitted to the slide and frame, and some special coatings will be applied to the slide and barrel to protect against corrosion, increase longevity of the parts, and reduce friction. One of those coatings will be nickel boron, applied to the highly polished barrel. The other coating will be applied to the slide, over top of nickel boron. It’s a proprietary coating that’s still experimental but it’s 2.5x harder than nickel boron and very slick. And very thin. It’s held up well in testing so far on AR15 BCGs so I’m expecting good results on the slide.

After all that is done I’ll do the grip modifications and trigger work, possibly also swap the sights out. It’s wearing Trijicon Novak style night sights now. I might swap to some Trinicon HD night sights.

Seeing how this is a concealed carry gun the coatings, grip work, sights all play a big role in how effective the tool will be for the intended job. Protecting the gun from the elements will extend its reliability and service life. My
Goal was to optimize it for use as an edc gun in every way possible. The sights are part of that as well.

If anyone is interested in having custom work done to their Glock or purchasing a custom Glock new, Evolution Weaponry can take care of you.
