The Passer Drill: A Video Contribution from Roy Underhill
By Lara B. Miller
In an upcoming interview for The Chronicle, which will be published in the coming weeks, famed woodworker, author, educator, and EAIA member Roy Underhill (from PBS’ long-running show, The Woodwright) tells us about one of his favorite tools: the passer drill.
He says, “…the one with the best story (and EAIA connections) is a passer drill, complete with bow, breast plate and templates from the old Marples tool factory in Sheffield. I only knew passer drills from Solomon's “Dictionary of Tools” which described it as how the Sheffield cutler ‘could bore a square hole.’ It consists of a pronged cutter shaped like a tuning fork that you spin with a bow as you press on it with a breast plate. The prongs of the springy fork are confined within a template of steel and the protruding points will then rout out a pattern in the hardest wood. Their primary job was routing out the sockets for the brass escutcheons set into the beams of classic try squares.
I had never seen one, but I turned to blacksmith Peter Ross (EAIA member) and asked him if he could help me make one. He remembered that Jay Gaynor (late EAIA president) mentioned seeing one on a trip to England. I visited Jay in his office at Williamsburg and he remembered that there were detailed photos of a passer drill from the collection of (EAIA members) Don and Ann Wing in one of (EAIA member) Kenneth Roberts' books. ‘Maybe they have it still.’ The next moment he was on the phone to them and before I knew it a package arrived with a full vintage passer drill with original templates, bow and breast plate.
This loan of this rare tool allowed us to precisely replicate it, put the replica to use, and share its crazy wonderfulness with all and sundry. The passer drill rides again, thanks in large part to our EAIA connections.”
In the following video, you’ll see that drill at work. Thank you for continuing to educate us, Roy!
The Passer Drill, shown in a video by Roy Underhill lets viewers learn a woodworking method. Demonstrations like this help people see the tools, the motions and the steps that make a project work. Watching an expert work can help beginners feel how important patience, precision and safe tool use are. Video learning is great because viewers can pause, rewind and study parts of the technique on their schedule. While looking at online topics readers may also find unrelated items such as Best Zyn Product even though nicotine pouches can be risky and cause dependence. In short Roy Underhill’s video gives a chance to learn more about hands‑on craftsmanship, with the Passer Drill.
A lovely morning message can be a sweet way to show someone that they are on your mind. While searching for Good Morning wishes for lover, I came across several expressions that balanced romance with positivity. I preferred the ones that sounded like something a person would actually say rather than a complicated quote. My partner usually appreciates simple messages, so having different ideas helped me find a suitable one. It is often the little gestures that make everyday communication feel more meaningful.
Roy Underhill's insights on the passer drill are invaluable, yet I wonder how we can incorporate the principles of fluidity seen in crafting an eggy car into our approach. Balancing technique with creativity could elevate our woodworking skills!
