SABINO’s Boiler Ready to Go

The new custom-built boiler for steamboat Sabino has been completed and passed its initial pressure test. This is an important step in the restoration and continues the schedule to return the vessel to operation on the Mystic River in July.

The boiler was designed and fabricated by Potts Welding & Boiler Repair, Inc., a company in Delaware that specializes in the building of boilers and related parts for use all over the world.

“They are used to building boilers as big as our entire shop,” said Jason Cabral, Sabino‘s chief engineer.

The new boiler is fabricated out of steel and had to be reverse engineered from the previous unit as no blueprints were available. Sabino‘s old boiler dates from 1940 when the U.S. Navy operated the vessel on Maine’s Casco Bay, but the design goes back to the late 19th century.

The old boiler was manufactured by the Almy Water-Tube Boiler Company of Providence, R.I. It was the vessel’s third boiler since she was launched in 1908. It powered the steamboat for nearly three-quarters of her life on the water, including passenger service in Maine, as a private attraction in Massachusetts, and finally for more than 40 years on the Mystic River for Mystic Seaport. It is now on display in the lobby of the Thompson Exhibition Building.

“The design process sought to create a modern boiler as close to the geometry and architecture of the one we took out of the vessel, but one that would meet all of the necessary safety and regulatory requirements,” said Dana Hewson, vice president for watercraft preservation and programs. “We also anticipate this boiler will be more efficient.”

At first glance the Almy boiler appears to be a small simple design. However there were many years of trial and error refinement incorporated into the design when it was built,” said David Sollish, an engineer who consulted of the project. “Since there were no design drawings or calculations to work with the boiler had to be reverse engineered. This is considerably more difficult than just designing a boiler from scratch. The design calculations had to all be done by hand.”

Sollish said the major challenge centered around the fuel. Coal used to be the backbone of the boiler industry and there were many boiler companies to choose from 40 years ago. Today, that coal boiler capability has all but disappeared in the United States and they could find only one manufacturer, Potts, with the capability and interest in tackling a custom marine boiler design such as this.

“The problem is coal burns differently from oil or gas or even wood. A boiler designed to fire coal is vastly different from a boiler designed to burn other fuels,” said Sollish.

Sabino will continue to be powered by her original two-cylinder expansion engine that was manufactured by J. H. Payne & Son in nearby Noank, CT, in 1908.

The fire is lit in the middle and the heat passing by the water tubes turns the water inside into steam, which is collected in the steam drum and passed on to power the engine.

A new base, or fire box, is being built that the boiler will sit in and the outer casing will be reused. The casing has been cleaned and internally modified to hold a new ceramic refractory material (insulation) that will be far more efficient than the old fire bricks. It will bolted back on and then the whole unit will be dropped into the boat in one piece. With only 3 inches of clearance in the mechanical space, there is not sufficient room to assemble the boiler in place.

The Shipyard is presently reinstalling all of the systems using a combination of brass and black steel pipe. Everything had to be disassembled, cleaned, inspected, and reassembled. Only those items needing replacement are being replaced, consistent with the Museum’s preservation practice. In addition, the engineers have been carefully logging and documenting all work for U.S. Coast Guard (USCG) review and inspection.

Cabral said the project is something of a learning opportunity for all involved. There are not many boilers and engines like this in operation in the country, so the USCG has created a special team for Sabino to spread the experience and knowledge generated from this project.

About Potts Welding

MAYFLOWER II Live Oaks Part of Legacy

For two of the families donating wood to the Mayflower II restoration project, the trees are more than just wood. They are part of their family story.

Shipwrights from Mystic Seaport and Plimoth Plantation were at two sites on the Gulf Coast in Mississippi and Louisiana this week to harvest live oak trees to be used in the ship’s restoration, which is being carried out in the Museum’s Shipyard.

Mayflower II is a reproduction of the ship that transported the Pilgrims to America in 1620. She is owned by Plimoth Plantation, which is restoring the vessel in preparation to take her back to sea in connection with the celebration of the 400th anniversary of the Pilgrims’ arrival in Massachusetts.

Wood from the trees will be used to replace frames and other structural pieces on the ship.

“Live oak is highly sought after in wooden shipbuilding because it is very dense, hard, and resists rot better than almost all mayflower ii woodother species in North America,” said Quentin Snediker, the Shipyard Director at Mystic Seaport. “The crooks and curves typical of the trees are ideal for the fabrication of many of the structural parts as there are few straight lines and right angles on a wooden ship.”

Sam Bordelon is the owner of the property in Belle Chase, Louisiana, where 12 live oak trees were harvested. The property where these trees are located has been in his family for more than 100 years, and many of the trees are considerably older than that. He loves them — he’s a software engineer by profession, but he is a hobbyist woodworker.

The trees are coming down as part of the construction of a right-of-way by a power company. Sam struggled with the thought of losing these trees and having the pass cutting through his property. But then he spoke with a friend about what was happening, he was reminded of the USS Constitution restoration and the use of live oak in that project. (The Constitution was originally built with live oak in the 1790s, and saw action against the British during the war of 1812, receiving the nickname “Old Ironsides” due to the strength of its construction.)

Sam did some research online to see if there were any ship restoration projects happening anywhere that might want live oak, and he found the restoration of Mayflower II at Mystic Seaport. He reached out to Snediker, and after talking with him and Whit Perry, Plimoth Plantation’s Director of Maritime Preservation and Operations, arrangements were made for a crew from the two museums to come down to Louisiana to oversee the harvesting of the trees.

Sam said that being able to offer the wood for a ship as important as Mayflower II made “the best of the situation.”

In Pass Christian, Miss., two live oaks saved Diane Brugger’s life during Hurricane Katrina. Diane and her husband Tony owned the Harbour Oaks Bed and Breakfast Inn, and they did not evacuate when the storm neared because they thought the hurricane was headed straight for New Orleans. The inn was 33 feet above sea level, so they thought they were safe, even with the predicted 25-foot storm surge. As the water rose, the Bruggers sheltered on the second floor, and then suddenly, a tornado hit.

“We were sitting in the bed and the dogs were just going crazy, and the house, you would feel it sort of lift up like a boat and then settle back,” Diane Brugger said in an interview with ABC News. “Then when the house went up and it didn’t quite go right back down the way it was supposed to and we got up and then that’s when the walls fell away,” Brugger said. “When the part of the ceiling came down, it caught [Tony’s] head and just took him right under.”

Diane grabbed onto two live oaks in her yard, and clung for six hours as the water swept by.

At one time her property had 12 live oaks, Diane said, ranging in age from 250 to 500 years old. Two remained in the wake of the storm (the ones she clung to had to be removed after the storm because of damage). Of the two, one was recently struck by lightning and had to be taken down. This is the tree she is donating to Mayflower II.

“It will make me so happy, and my family, to know that this tree will not wind up in a landfill somewhere but instead with something as historic as where it came from,” she said.

Plimoth’s Perry appreciates the generous contribution that the landowners have made to the restoration of the historic ship. “These trees will live on in perpetuity, and make it possible for the ship to sail on for generations to come.”

Mystic Seaport Opens “On Land and On Sea”

A new exhibition at Mystic Seaport launching at the start of Women’s History Month chronicles both the luxurious and the hardworking life of women in the 20th century as seen through the lenses of the Rosenfeld family of photographers.

Entitled “On Land and On Sea: A Century of Women in the Rosenfeld Collection,” these 70 photographs tell the story of lives of privilege and leisure and also lives of working-class women from the turn of the last century through the 1950s. Photos that depict impeccably attired ladies onboard sleek schooners tell one story, while images of young women training to be telephone operators in New York City tell another.

The exhibition is based on the book of the same title by Margaret L. Andersen Rosenfeld, a professor of Sociology at the University of Delaware and the daughter-in-law of Stanley Rosenfeld. The book was published by Mystic Seaport in 2007.

“The Rosenfelds are best known for their stunning images of large racing yachts under sail, but they also captured images of people and everyday events as part of their commercial photography work,” said Elysa Engelman, Director of Exhibits at Mystic Seaport. “The issues represented in these photographs still resonate to the contemporary viewer and they are depicted with the Rosenfelds’ usual attention to detail and striking composition.”

The exhibition is organized around seven themes that show the different dimensions of women’s lives in the 20th century:

• Learning the Ropes
• The Daily Grind: Women and Work
• Lifelines: Women as Care Workers
• Spirit, Sports, and Spectators
• Displaying Womanhood
• In the Yard
• Women at the Wheel

Among the photographs in the exhibition, there are aviators and athletes, suffragettes on the march, baby nurses and mothers caring for their children. Each photo provides a fascinating glimpse into the social history of women as depicted in commercial photography, from young girls having fun messing about on small boats to fashion models and society matrons. Many of these photographs are on display for the first time.

The Rosenfeld Collection, acquired by Mystic Seaport in 1984, is one of the largest archives of maritime photographs in the United States. This Collection of nearly one million pieces documents the period from 1881 to 1992. The Collection is built on the inventory of the Morris Rosenfeld & Sons photographic business, which was located in New York City from 1910 until the late 1970s. The firm grew as sons David, Stanley, and William joined their father’s business. Although they became famous as yachting photographers–most notably their coverage of the America’s Cup starting in 1920–the early work of the Rosenfelds included assignments for such firms as the New York-based entities of the Bell System from the 1910s through the 1940s. This exhibition compiles selected images of women throughout the entire collection, some nautical, and some not, to tell the social history of women through the eyes of the Rosenfelds.

As part of the opening of the exhibition, Margaret Andersen Rosenfeld will be present at a book signing on Saturday, March 4, from 10 to 11 a.m. in the Thompson Exhibition Building.

Bells Will Be Ringing

Jim Anderson, owner of Time And Again clock shop in Waterford, grew up in southeastern Connecticut and lived here for many years before moving away for a time because of work. He returned in 2014, and was looking for a volunteer opportunity, when he noticed that the tower clock in the Museum’s Greenmanville Church didn’t work.

Anderson met with Paul O’Pecko, vice president of research collections and director of the G.W. Blunt White Library, and offered his expertise and his services to get the four clock faces running and the bells chiming again.

The Greenmanville Church dates to 1851, although its original location was down Greenmanville Avenue (adjacent to the Museum’s South Entrance). It was moved to its current location on the McGraw Quadrangle in 1954 after it was acquired by Mystic Seaport in 1951. The original steeple had no clocks and had been broken up in 1902. It was about 3 feet shorter than the present one, which was built by the Museum in 1954 after the building’s relocation.

The clock was built in 1857 by the Howard Clock Company of Waltham, Mass. for a New England college. It had been in storage since 1931, and not maintained. It was sent to Mystic Seaport and the steeple was modified to accommodate the four clock faces.

When the clock was installed in the church, the decision was made to showcase the mechanics as much as possible to fit in with the Museum’s mission. The movement was located in the southwest corner of the first floor, with the strike weights and pendulum in the basement, and a fairly circuitous transmission system to carry the time output from the movement to the tower located some two stories above.

It worked for several decades, looked after by the late Frank Murphy and then the late Don Treworgy, director of the Planetarium. As time went by, one face after another stopped working until only one was left. After both Murphy and Treworgy passed away, maintenance fell by the wayside. It has been completely stopped for about seven years.

O’Pecko brought together Anderson and volunteer Bill Michael, a mechanical engineer, and they worked on the project for about 15 months. Anderson estimates he put in about 120 hours.

When he first got inside the clock, Anderson said he tested the pendulum and realized right away there was not enough power to keep the pendulum swinging. Throughout the mechanisms, Anderson discovered loose screws, lots of dirt and dust, worn gears and bushings. “As we got deeper and deeper into the clock, we decided we needed to really do the whole thing so that no one will have to touch it again for many years,” Anderson said. So they took apart the whole clock and hand cleaned it section by section, every widget, every gear, every bushing, every nut and bolt.

Then they rebuilt it, making some improvements along the way to ensure smooth operation and proper synchronization moving forward. On January 12, they restarted it and it once again began telling time and chiming the hours.

The clock remains a work in progress, as adjustments continue to be needed.

In the first week, it stopped twice and after troubleshooting they decided to detach the East-side clock (facing Greenmanville Avenue) because of problems within the mechanisms. That will be fixed when the opportunity arises for the hands to be removed from the outside (which will require a cherry picker).

Even with one of the four faces not working, Anderson is justifiably proud of this restoration project. “It’s something you may only get to do once in your life,” he said, “like being able to go up inside Big Ben or something. I really enjoyed doing it, and being able to troubleshoot the whole thing and make it work. Even after months and months of this, I knew it would be something we’d be proud that we accomplished. This is my Big Ben.”

No Fault In Our Stars

Annual maintenance of Treworgy Planetarium’s projector takes place every winter

Every few thousand miles you bring your car into the shop for a tune up. Every thousand or so hours, Mystic Seaport does the same with its Treworgy Planetarium projector. Except in the case of the Spitz A3P optical mechanical projector, the “mechanic” comes to the Museum.

John Hare, founder of Ash Enterprises, spends his career traveling the globe performing maintenance and upkeep on planetarium equipment. He estimates there are 3,000 to 4,000 planetariums in the world, and about 1,500 in the United States. Hare has been working on the Museum’s projector for eight years, visiting annually for a few days every winter to completely clean and realign the equipment.

Hare founded Ash in 1971 after he realized while working for the Michigan State University planetarium that there was a market for projector maintenance. He started his planetarium career after serving in the U.S. Navy running sonar on a destroyer escort. Discharged in 1963, he took a job with Spitz Inc., the company that manufactures many of the world’s planetarium’s projectors. After a couple of years there he moved over to work for Michigan State, and went back to college to earn a degree in telecommunications. After 10 years, he decided to go out on his own. Today, Ash has five employees and 150 regular clients, including Mystic Seaport.

The Museum’s projector is a workhorse, notes Brian J. Koehler, supervisor of the Treworgy Planetarium. “We estimate the projector works about a thousand hours a year,” Koehler says. “In the summer, we do four shows a day, seven days a week. In the winter, we do seven shows a week and have school groups on our other days.”

The projector at Treworgy Planetarium is an Optical Mechanical Projector, made by Spitz Inc., Hare’s old employer. It is an older style of planetarium projector. The newer projectors are digital, which use video. The Museum’s projector uses a Star Ball to produce the star field visitors see in the dome over their heads. The Star Ball has a xenon arc lamp inside it, which illuminates the dome through the Star Ball. The ball has more than a thousand pinprick-sized holes in it, and the xenon arc lamp pushes light through those holes to make the stars above. This type of lamp is used for brilliance and for its compact size, Hare notes. He replaced it on this visit because it had been in for two years, and as it wears out, the stars “get fuzzy.”

This type of projector “renders the real sky” for visitors, Hare explains. Digital projectors project video onto the dome. “This is a much higher resolution than a digital projector,” Hare says. “This is more realistic and accurate. The drawback is with this type, we can only represent the sky as we see it from Earth. With a digital system, you can show perspectives from anywhere. It makes sense for the Seaport to have this type, since it engages in celestial navigation education and how the stars relate to maritime endeavors. It’s old, but it’s far from obsolete. It could last another 50 years.”

Koehler says this projector was installed in 2009. “It was a conscious decision to keep with the mechanical projector,” he says, “because in our opinion, the digital projection of the sky is not accurate enough. We believe this creates a more authentic night sky. We don’t want you to feel like you are looking at a movie – we want you to feel like you are looking at the stars.”

The authentic experience is important because Mystic Seaport is a maritime history museum that offers numerous celestial navigation classes, Koehler says, as well as astronomy outreach programs to many area schools and colleges, in addition to its regular planetarium shows offered to the general public.

Hare spends his time in the planetarium carefully dismantling the projector, cleaning every ring, gear, slip and part, and then reassembling it. After that, he meticulously realigns it so that all the stars and planets and the Sun are in the correct location, for all times of day and night. He makes sure everything is properly focused and uniformly illuminated. When he’s done, “you can definitely see a difference,” Koehler says. “The stars are sharp and bright.”
