Tools of the Trade: The Whetstone Part II

Today we’ll be continuing our whetstone discussion by looking deeper into what was available in Pennsylvania in the mid-18th century and finish by showing how to practically apply these techniques in a woodworking shop.


To recap: Whetstones are a type of fine sharpening stone, and from Joseph Moxon’s Art of Joinery [1] we know that woodworkers in 18th century used them as the final step of the sharpening process, where they would first grind a hollow into their blade, then smooth it out using a flat grindstone or ragstone, and finish it on a whetstone.


Sharpening in 18th century Pennsylvania

There isn’t much information about sharpening in Pennsylvania in the period, or at least nothing so thorough as Moxon, but what we do have are newspaper advertisements which show a near constant importation of sharpening stones from London and Europe. From what I’ve found in the Pennsylvania Gazette these were the most common stones found in Philadelphia and the surrounding counties:


  • Whetstones - These often show up in advertisements of ships coming from London, which I believe indicates that they were likely using stones from England, however more research is needed before I can give a true list of what these stones would have been.

  • Crum Creek ragstones- These local stones were being commercially quarried along Crum Creek (near Chester in southeastern Pennsylvania) by at least 1742, though the advertisement suggests they were in use before then.[2] We’re currently doing research on some stones which might be original examples of these; they’ll likely get a whole blog post to themselves at some point.

  • Norway ragstones - These are coarser stones from Scandinavia, some of which are still available from Sweden. [3]

  • Bristol and Newcastle grindstones - These are English sandstone grinding wheels that were imported in great quantities. This is most likely what colonists were using as their grindstones.

  • Meyland/Moyland stones - According to Sebastian Seba of the Razor Love Stones blog, this is likely the period spelling of Mailänder Stones, which are a coarse stone from Milan, Italy.[4]

  • Turkey Oil Stones - These were a very fine stone imported from the eastern Mediterranean, showing up in Philadelphia by at least 1753, if not earlier. [5]

Because of the numerous advertisements showing stones being imported, I think it’s likely that woodworkers in this region were using mostly English and European stones to sharpen, with the notable exception of Crum Creek ragstones. This actually goes against my original assumption that they would have used mostly locally-quarried stones, but that’s the joy of research; you don’t know what you don’t know, and sometimes you’re wrong about what you think you do know!


Applying Moxon to the real world

Now we are finally ready to take Moxon’s instructions and use them to sharpen our tools.


Let’s take a look at my plane iron. To start, it was very dull, wouldn’t take a clean shaving, and tended to tear out the wood, rather than shave it cleanly.


I first ground it on my bench grinder. This is admittedly a more modern version, likely from the

1930s, but it is of similar size to the smaller grinders which can be seen in English illustrations from the period.


I then turned the iron over, and on a medium-grit stone (this one from Smithfield, Rhode Island), I pushed the gratings back to the other side and smoothed the flat side of the iron.


I then held the iron in front and placed the stone on the basil as Moxon described it. Rubbing in a circular motion, I continued to smooth the basil.


Finally, I took a piece of very fine slate and finished the edge on that. At this point I had worked the gratings off of the edge, which indicates that I’ve made an edge that is incredibly thin and sharp.


Now to test it out. As you can see, it makes beautiful and smooth shavings, which means this method of sharpening works!


We’ll continue to discuss whetstones as more research is done. I hope at some point to be able to somewhat definitively say what stones were available in the period, and what a “Crum Creek ragstone” actually was.


Next week we’ll be looking at another very important tool for woodworking in the period: dividers, these were an essential layout tool. We’ll also be discussing how we laid out our waterwheel!


As always - stay home, stay safe, and check back soon!

As events develop with the COVID-19 virus, Newlin Grist Mill (NGM) continues to closely monitor the situation and follow guidance from the CDC and all levels of government including social distancing and restrictions on gatherings. The NGM has taken the following steps through May 31:

  • The NGM Visitor Center, Archive, Blacksmith Shop, Millwright Shop, and public restrooms will be closed;

  • All tours, programs and events have been postponed or cancelled during this period;

  • Pond Fishing will remain closed until further notice;

  • The Fishing Breakfast has been cancelled;

  • Rentals and photography sessions are being cancelled for this period of time;

  • There will be no Volunteer Wednesday Workdays;

  • The trails will remain open but parking is limited

Decisions concerning additional closings will follow based on the developing situation. Please check back for updates.

While the trails at Newlin Grist Mill remain accessible while the site is closed due to the COVID-19 pandemic, we do want to remind everyone of a few things:

  • Continue to observe proper social distancing when you are on the trails. If you are ill or have been around anyone who is ill or has been exposed to the virus, please remain at home. If you arrive and find that the parking lot is crowded, please postpone your visit to another time.  

  • Please remember that all dogs must be on a leash that is held securely by the owner at all times. This is a township law, and it is to protect the health and safety of all park visitors (human and canine) and the wildlife in the park.

  • The park contains unique habitats that are home to sensitive plants and animals, some of which are being monitored through ongoing scientific surveys.  Please stay on the trails to avoid disturbances (wading, dip netting, collecting, rock throwing etc.) that could damage wildlife and vegetation. 

  • Remember that collecting of any kind, including plants and animals, is prohibited in the park.

  
We appreciate your understanding and support during this challenging time.
