In the above video you’ll see my fascinating trip to Colonial Williamsburg as part of a study of a relatively unknown type of molding plane, called “Mother Planes”.
On a grant from the Early American Industries Association, Bill Anderson, Larry Preuss, and myself studied Williamsburg’s collection of 400+ Mother Planes to see what we could learn about molding plane construction.
What is a Mother Plane?
In the 1800’s, larger molding plane manufactures used “mother planes” to cut a particular profile to larger quantities of molding planes. An attached fence is a main characteristic of a mother plane.
The folks at Colonial Williamsburg were kind enough to host us for several days in the top floor of the historic Capitol building.
Below you’ll see our research team (from left to right) Bill Anderson (the founder of the project), Larry Preuss (an expert plane maker from Michigan), Erik Goldstein (Curator of Mechanical Arts & Numismatics at Colonial Williamsburg Foundation), and Joshua Farnsworth (I took sevaral thousand photographs & scans of the mother planes):
Our study took place over several days in October 2014 and Feburary 2015. I’ll have to admit, prior to Bill’s invitation to join this study I hadn’t even heard of Mother Planes. But I quickly fell in love with the lovely mother planes, just as I had with molding planes in general.
Here are all my videos & articles from Colonial Williamsburg:
This is my “cave” where I spent several days photographing and scanning nearly 400 mother planes:
After removing the iron and wedge, we scanned the “toe” of each mother plane, then photographed each side. Here are some photographs of different views of some fascinating mother planes:
In addition to photographing and scanning each plane, Bill and Larry spent considerable time inspecting each mother plane for interesting characteristics such as cutting profile, dimension, size marks, and maker marks.
Details were meticulously recorded on detailed data sheets that Bill created, and each plane was assigned a number:
Erik Goldstein was kind enough to spend many hours with us to ensure that the valuable plane collection was handled properly:
Over the course of our stay, Erik gave us some amazing tours of rarely-visited parts of the capitol building, including incredible tool collections and a trek up the steep steps of the bell tower, which has only been visited by a handful of people since it’s dedication by President Franklin D. Roosevelt in the 1940’s.
Below you’ll see some fun photographs that I took of the Capital Building at Colonial Williamsburg (I highly recommend a visit to this 18th century wonderland):
