APM to Present Smithsonian Poster Exhibition Highlighting the History of Women Inventors in the United States

March 1, 2022: Windsor, VT – Throughout American history, women with diverse backgrounds and interests created inventions that changed lives every day. But women haven’t always had equal opportunities to be inventors or received as much recognition. The Smithsonian and the United States Patent and Trademark Office present “Picturing Women Inventors,” a poster exhibition that explores the inventions of 19 highly accomplished American women. Astronauts, computer pioneers, and businesswomen join athletes, engineers, and even teenagers in this remarkable group of inventors. The posters will be on view at the American Precision Museum March 1 through 31st, in conjunction with Women’s History Month.

“Picturing Women Inventors” showcases the breakthroughs, motivations, and challenges women encountered while pursuing their goals as inventors. The poster exhibition highlights stories of inventors like Marilyn Hamilton, who after a hang-gliding accident in 1978 left her paralyzed, invented a lightweight wheelchair that was easy to maneuver. Diversity of background and age are showcased including inventor Alexis Lewis, who at 12-years-old in 2011 was inspired to adapt a traditional Native American sled, called a travois, by adding wheels to create a simpler way to transport families and their belongings in Somalia.

The exhibit is a natural complement to the stories of innovation and invention already on display at APM.  This poster exhibition was designed to educate and inspire young people to see themselves as future inventors.  During the winter, when the museum is not heated, admission is free (although donations are welcome). Visitors are welcome to tour the museum, bearing the cold in mind.

“Picturing Women Inventors” is distributed at no cost to schools, libraries, museums and community organizations by the Smithsonian Institution Traveling Exhibition Service in collaboration with the Lemelson Center for the Study of Invention and Innovation and the United States Patent and Trademark Office. It’s sponsored by Lyda Hill Philanthropies IF/THEN Initiative and Ericsson.

“Patterns and Molds”:  Temporary Exhibit at American Precision Museum

 January 14, 2022: Windsor, VT – The American Precision Museum’s new temporary exhibit, “Patterns and Molds,” opens at 10:00 a.m. on Friday, January 14, 2022.  This special selection of items is drawn from the Museum’s archives and remains on exhibit from 10 am to 5 pm through Monday, February 14.   The exhibit includes video elements explaining molding processes, live demonstrations of thermoforming, and more.   Although many of the patterns resemble simple shapes, some are more complex, and all ultimately became parts of machines.

“When we talk about cast-iron, we’re really talking about molten iron being poured into a mold, and the resulting casting,” explained Executive Director Steve Dalessio.   “The pattern is the original design the mold is made from.”     The museum has hundreds of these patterns in its collection, usually wooden. These patterns were often used in foundries. The patternmaker in the 1800s and early 1900s often learned from a master or from books (and a sampling of these books will also be on display). “The American Precision Museum has so many artifacts in its collection that the public does not get to see regularly,” says Dalessio. “This exhibit is an opportunity for us to share unique objects that have never been put on display.” 

During the winter, when the museum is not heated, admission is free (although donations are welcome). This special exhibit takes place in the heated section of the museum.  The exhibit is open weekdays from 10-5 pm.

Exhibit links with Education Kit “Achieving Repeatability “

The exhibit also ties in with the museum’s next education kit, “Achieving Repeatability”.  This interdisciplinary kit for kids in 4th   through 6th  grade will be available to local teachers and informal educators free of charge in February. The kit includes lesson slides and all the physical materials a student would need to create a cookie cutter that tessellates, build a catapult that’s both accurate and precise, exchange the parts of a clicking ballpoint pen, and more. The lessons tie in manufacturing, history, and STEM with art and the humanities. 


Model Engineering Show Returns, Updates at the American Precision Museum

 August 5, 2021 – Since 1999, the American Precision Museum has hosted a gathering of makers and builders known as the Model Engineering Show.   The American Precision Museum’s 20th Model Engineering Show will take place at the museum Saturday, October 2 from 9:00am-4:00pm. 

The American Precision Museum’s Model Engineering Show has become an October tradition giving visitors the chance to see the work of some of New England’s finest model engineers. Perfection is the hallmark of the model engineering and miniature movement, and visitors to the show will experience some of the best. 

In past years, the Model Engineering Show in fact was held in two locations and had over 30 vendors and exhibitors.  The 2021 show will be much smaller – only to be held at the museum. And in order to make the best use of the limited space, the show will require exhibitors to apply and be approved.

The show’s date was chosen for several reasons: to better accommodate potential exhibitors during the beginning of “leaf peeper season” in rural Vermont, and also to coincide with National Manufacturing Day.  “National Manufacturing Day (or MFG Day) is always held the first Friday in October, and encourages manufacturers, schools, parents, and allies to work together to build a future workforce.   And there is no more inspiring way to show the joy of making things than the Model Engineering Show,” said associate director Alice Cable. 

The museum’s education strategy introduces young people to “making things” and consider a career in manufacturing through digital resources, classroom outreach and onsite programs that connect history, STEAM (Science, Technology, Engineering, Art/Design, Mathematics), and machines.

The museum also has a major new exhibit for 2021, which tells the important story of how precision manufacturing changed from “Made by Hand” to “Made by Machine.”  Displays of early machinery are integrated into the broad story of American industrial history, enabling visitors to learn more of the important role the manufacturing industry continues to play in shaping American culture and society.

For those interested in exhibiting, volunteering, or being a vendor, visit the museum’s web site: www.americanprecision.org to apply online and to obtain general information about this event.  Call the museum at 802.674.5781 for more details.  The museum exhibits will close for the season October 31st, 2021 but may be open by appointment during the winter.

Updates for the 2021 Season: “Made by Hand to Made By Machine”

March 15, 2021 (Windsor, VT):   When the museum opens for the season on May 1st, visitors can expect to see a few changes.   New displays will tell the important story of how precision manufacturing changed from “Made by Hand” to “Made by Machine.”    In the museum today, displays of early machinery are integrated into the broad story of American industrial history, enabling visitors to learn more of the important role the manufacturing industry continues to play in shaping American culture and society.   “This new exhibit will bring to light how products were first made by hand and then made by machine, through the brilliance of Kendall, Robbins and Lawrence,” said Executive Director Steve Dalessio.  The new display will feature updated lighting and media, a new hand-tool display, and much more. “We look forward to sharing the new exhibit with you whether you’re here at the museum or visiting us online,” added Dalessio.

Additionally, the Science and Technology of Measurement display has had an update for the new year.  As part of the statewide exhibit 2020 Vision: Reflecting on a World-Changing Year,’  the update includes the measurement of heat, due to unprecedented use of forehead thermometers for covid-19 symptom checking. The museums’ collection of pyrometers and thermometers includes devices that can measure up to 3000 degrees Fahrenheit.  Beside the measurement of heat and temperature, this display also features devices that measure speed, distance, time, power, and hardness.


Return of the Miniatures:  Models & Miniatures Virtual Exhibit

January 13, 2021 (Windsor, VT):  One year ago, the American Precision Museum hosted a Models & Miniatures temporary exhibit.  The minis are returning, but due to COVID-19 rates, the show will be virtual this year. 

Between January 16th and January 29th, a new artifact will be featured daily on the museum’s social media channels and website.   Local TV station Windsor-On-Air will also film the temporary exhibit so viewers can experience a walkthrough, as they’ve done for the miniatures and for the Mechanical Arts show, both in 2020.

The show includes many favorites from last year, but also some new items.  Several will be hooked up to a compressed air system.   “Last year, when we brought out the models and miniatures, we discovered that many of these steam engines should be functional.  Compressed air will fulfill the same function as steam, and allow these models to work,” said Executive Director Steve Dalessio.  “My favorites are of course the very tiny hand tools that are less than one inch long, but I also like the steam whistle and the engines with flywheels.”

Mastercam Announces Exhibit Partnership with Haas and the American Precision Museum

September 22, 2020 (Tolland, Conn.) – CNC Software, Inc., developers of Mastercam, the world’s leading CAD/CAM software, has announced a new partnership with the American Precision Museum (APM) and Haas Automation. APM combines the atmosphere of an original 19th century water-powered manufacturing facility with a world-class collection of historic machines. It explores industrial history in the context of innovation, creative problem solving, and the impact of precision manufacturing on American history and culture.

The APM factory was first powered by a great water wheel, located in the basement, which drove a drum that carried belts up through the ceiling to the overhead line shafts on the factory floor. Those shafts turned smaller belts that powered the machines. APM is partnering with Mastercam to recreate a waterwheel to have on display in the museum demonstrating how running water was turned into power to drive the building.

Waterwheel recreated at the American Precision Museum.

The Applications Engineers at CNC Software, Inc. designed a functional scaled-down version of the original waterwheel found at APM. To keep it as realistic as possible, the model design was inspired by a 2009 study of the original factory and wheel. The assembly was designed in Mastercam for SOLIDWORKS® and programmed and machined using Mastercam. Most of the assembly is made from ¾” prefinished plywood and was machined down on a 3-axis router. The mechanical components are aluminum and steel and machined on a Haas VF2 CNC, taking waterwheel power into the 21st century.The scaled-down version has a working drive gear assembly, and for display purposes is not powered by water but instead uses a small pellet stove gear motor.

“CNC Software is proud to partner with the American Precision Museum. APM is helping to tell the story of how mass production changed the world and shaped America,” says Meghan West, CEO of CNC Software. “APM is looking to recreate a waterwheel, and we are honored to help reproduce it with Mastercam. Exhibits like this are intended to spark imaginations and inspire younger generations to get involved with manufacturing. We are 100% behind that.”

Toni Neary, Director of Education for the Morris Group – Haas Division, “We are so thrilled that HFO Trident, Haas, Mastercam, and the American Precision Museum have found this way to partner and build such a dynamic project. Our organizations are committed to growth through education, sparking awareness of careers in manufacturing, and good old American ingenuity. This waterwheel is the culmination of those passions. The team at Mastercam has worked to create a fun and exciting way to discuss the history of the museum and integrated modern manufacturing technologies to replicate parts of our history. We so appreciate the time and craftsmanship in making this vision a reality.”

Steve Dalessio, Executive Director of APM, further states, “Using advanced manufacturing methods to recreate an 1846 device is a great way for us to demonstrate how manufacturing continues to evolve. We’re so grateful to Mastercam for creating this model for us, because our education program will be able to use the exhibit to link science, history, and manufacturing.” The new display will be unveiled for Manufacturing Day 2020.

Stories of Ingenuity in the time of Coronavirus

April 22, 2020

  • The Wall Street Journal describes how companies are responding in much the same way they did during WWII: “It is a 21st-century version of the “Arsenal of Democracy,” the mobilization of industrial might that helped win World War II, only this time to make personal protective equipment, ventilators, tests and vaccines instead of uniforms, ammunition, tanks and bombers.”  Click here to read the article – which has even more inspiring stories.

  •  Some hospitals are inviting healthy local volunteers to make cloth masks as a backup resource*.   For example, Here’s the guidelines for hand-sewn masks: Fabric masks are a crisis response option when other supplies have been exhausted. Volunteers must be healthy, without signs of fever, coughing, or shortness of breath, and must not have been in contact with anyone suspected or confirmed to have COVID-19 in the past 14 days.Volunteer mask makers are asked to use 100% unused, non-metallic cotton fabric for the front, and 100% cotton or cotton flannel for the back, along with ¼” or 3/8” flat elastics. Instructions for the preferred mask type may be found here.   (*These cloth masks are not as effective as the ones used in hospitals; however, they can still be used in healthcare settings for other circumstances allowing the N95’s to be saved for COVID19 patients.)

  • From AutoNews:  “Ford Motor Co. plans to build respirators, ventilators and face shields in partnership with its UAW work force, manufacturing company 3M and GE Healthcare to aid medical workers as the coronavirus pandemic threatens to overwhelm their supply.  Known internally as “Project Apollo” and inspired by the quick-thinking ingenuity of the Apollo 13 space mission, executives on Tuesday said Ford workers plan to use car parts and factory tools to help get some equipment out to doctors, nurses and first responders as early as this week. ”  Read more here.

  • From Forbes:   “While this is a frightening time in so many ways, innovation has demonstrated innumerable times throughout history justified confidence and faith in the “invisible hand,” from the private sector’s transformative power in winning World War II to putting out oil well fires in Kuwait after being sabotaged at the end of the Gulf War in 1991.  ….Manufacturing capabilities are being expanded so they are ready to ramp up production once a successful medicine or vaccine is developed. And they are donating supplies and medicines around the world to help those affected. ”   Read more here 

  • From The Guardian:  “The last few weeks have seen a wave of ingenuity unleashed, with both garden-shed tinkerers and high-tech manufacturers scrambling to develop things that will combat the spread of Covid-19. Many of their innovations raise as many questions as they answer, though. …From 3D-printed respirator valves to UV-sanitising robots, here are 10 inventions that the battle against coronavirus has spawned so far.”  Read about them here.
