Just Peachey: Jeff’s Conservation Hand Tools Workshop

For one week in July, 2024, the Preservation Lab busted out belt sanders and opened the elbow grease to host a workshop taught by Jeff Peachey, learning all about making, modifying and maintaining our own hand tools. Jeff, a book conservator and master tool maker, brought all kinds of fun machinery and exciting tools for us to learn from and use. From hacksaws to pencil sharpeners, Jeff’s tool collection is inspiring, and we all left the week with some amazing new additions to our bench.

Delrin

We started the week off working with Delrin. Delrin, an acetal homopolymer plastic that appears similar to Teflon, was easy to shape with saws, files, scrapers and silicon carbide sandpapers. We burnished with sanding pads and polishing paper.

We started off with Delrin rods that we shaped into delicate heras. Heras are thin tools with spatula-like ends that Jeff says are great for delicate prying, inserting small amounts of adhesive, and lifting tape to name a few of the uses for this handy little tool.

We made a rough cut of the shape we wanted with the bandsaw, then smoothed everything out by going through a sandpaper grit progression. Once we’d crafted these, many of us tried our hand at making versatile Delrin folders. With lots of filing and sanding, this malleable Delrin was easy to manipulate into a variety of tool shapes, and no two tools were exactly alike.

Knives

Our second and third days with Jeff were all about M2 steel knifes, both sharpening them and making them. We learned all about using Jeff’s sharpening system and honed down our own Peachey paring knife. We also made two lifting knives out of Starrett 32T hacksaw blades by grinding the blades down on a belt sander and then taking them through the sharpening system with microfinishing films to achieve a sharp edge.

Sharpening knives turned out to be a complex process – a burr must be formed at each grit gradient before moving on to the finer grind, and if your hand position is off this could take some time. Furthermore, the wrong hand position could yield a bevel angle too big or too small on the plane of the knife. We aimed for an ideal bevel angle between 11 and 13 degrees.

Additional Knife Features

Some people chose to add grooves into the sides of their paring knives for a more comfortable grip; some of us chose to wrap our knife handles in leather and make horse butt sheaths for them. Matt was the bravest of all and mounted a custom carved wooden handle to his left-handed paring knife.

Grained Book Cloth

We also went over creating 19th century grained book cloth on our third day. Through toning, glazing, then pressing with a die that has your desired pattern, it’s possible to create book cloth that mimics the textures of 19th century book cloth. After going through the time-consuming process, the idea of making up large batches at one time became appealing.

Wood and Bamboo

On our fourth day we learned all about wood and bamboo carving. Using a chisel, wood plane or hatchet, we created the crude shape we wanted our wooden tools to take. Then we got to work sanding until the wood was smooth, and created a more precise shape. A final finish with nose grease or wax was optional.

Bamboo is great for creating thin, flexible tools. With our pieces of wood most of us created folders, but a few decided to make wooden handles for their knives or straight edges. Personally, my favorite tool I created the whole week was my wooden folder I made, though it was probably the hardest to create. I had to shape it using a small hatchet, then sand it for quite some time before it took on the shape that I wanted.

Stainless Steel

Our final day with Jeff was spent shaping stainless steel tools, which to me was the hardest material we worked with, as it took a lot of patience with the belt sander, and the metal was prone to heating up quickly and potentially burning our fingers. We created straight edges or 45 degree triangles, and even learned how to drill holes and attach small handles to these tools. We also had a thicker piece of stainless steel for creating a folder, which I found the most challenging of all. The stainless steel was harder to manipulate, understandably, and much less forgiving than the wood or Delrin.

We ended the week by testing the sharpness of our blades and doing a little show and tell of our favorite tools that we made. It was so amazing to see all the different tool shapes people were inspired to make based upon what they most used in their work.

Learning from Jeff was such an amazing opportunity, and it was so eye-opening and world-expanding to learn that so many of these tools we use every day can be created from our own hands.

Jeff did a fabulous job tailoring his tool-making workshop to the the availability of machinery and other logistics of our facility. As a result, the actual tools made in our version of this workshop vary from other workshops Jeff has taught, empowering us to keep making tools with our space in the future. If you ever have the chance to take this workshop, we highly recommend it!
