The Wheel at Newlin Grist Mill Still Isn't Turning. The Thursday Nights Run on Schedule Anyway.

"Water power, 18th century woodworking, what's not to love?" Michael Knight, an apprentice millwright, said that to CBS Philadelphia in October 2025 while volunteers at Newlin Grist Mill shaped a new waterwheel with hand tools. The wheel will be more than 15 feet across. The crew is building it entirely by hand, with no power tools. In that same story, the wheel was expected to be finished "this spring."

It is now October 2026, and the mill on South Cheyney Road is still not grinding. The site's own Location & Hours page says the mill "is not currently operational." Even so, the grounds open at dawn every day. The guided tours are running. Succession Fermentory has four Thursday evenings booked by the creek this month. The project missed its target date, but the site has kept running. The rebuild is now part of what visitors come to see.

Three Target Dates for One Wheel

The deadline has moved enough times to be a small local story of its own. Here is how it has shifted, using the dates in each source:

• Winter 2025: Newlin's own newsletter projected that the water system would be "fully operational in 2025" once the wheel and flume work was done.
• April 20, 2025: The Philadelphia Inquirer reported that completion was expected "by midsummer."
• October 22, 2025: The CBS Philadelphia story, republished on Patch, said the wheel "is expected to be complete this spring." Once finished, it will power two large millstones that grind wheat into flour.
• May 28, 2026: Connect Chadds Ford described the mill as "temporarily offline" while volunteers rebuild the wheel by hand. That article listed fresh-ground grain and cooking workshops as plans for when the mill returns.

No newer date has been announced. The official pages list no dedication or first grinding. The America 250 events page lists other programs and nothing about restarting the wheel. The honest answer to "when will it turn?" is that nobody has said.

The slow pace follows from the method. Site manager and archaeologist Keith Doms called the project "a unique experiment in seeing how things were done 250 years ago." The crew is recreating the mill as it looked in 1751, using period tools. A schedule set by 18th-century woodworking will be slower than one set by a contractor.

What a Visitor Actually Gets Right Now

Newlin has turned the construction into the tour. Guided tours run Wednesday through Friday at 1 p.m., and Saturday and Sunday at 11 a.m., 1 p.m. and 2 p.m. Visitors get "a rare opportunity to see the process of building a new waterwheel and waterbox." You can only go inside the mill on a guided tour. Tickets cost $10 per person and $6 for seniors and children 12 and under. Children under 3 get in free.

The building has a long history behind the scaffolding. Nathaniel Newlin built the mill in 1704, and it ran until 1941. The Nicholas Newlin Foundation, established in 1960, oversees the site today. Tours this fall show the mill's new wheel and waterbox while they are still being built by hand.

A second project is changing the site too. Newlin is raising its historic Visitor Center "to keep the historic structure safe from floods." The official blog describes new foundations as the first step. Next come reconnecting the plumbing and electricity, building a new ramp and porches, and grading the ground to move rainwater away from the building. For now, the public restrooms at the Visitor Center are open. The building itself stays closed "while we finish construction." The blog says the welcome desk moved for a while to the Archive building across from the mill.

Outside the buildings, nothing is closed. The preserve covers 160 acres with 8.5 miles of trails through upland grassland and river-bottom wetland. The grounds and trails are free and open daily from dawn to dusk. The West Branch of Chester Creek runs through the property. Stream fishing there is catch-and-release only and requires both a Pennsylvania license and a paid membership in the fly-fishing club.

Thursday Nights by the Creek, Through the End of October

The clearest sign that Newlin is still running is the Thursday calendar. Succession Fermentory comes to the park on Thursday evenings in May, June, September and October for weekly pop-up happy hours, selling beer and other drinks from 5 to 8 p.m. The listing invites people to "relax by the creek with friends," and it describes the evenings as "a great way to unwind after work or a walk in the park."

Succession is a short drive west. It's a farmhouse brewery at Stella Lou Farm, 432 Leaman Road in Cochranville. It makes spontaneously fermented, sour and farmhouse beers, using methods that include open fermentation and barrel aging. Partners Keith Hartwig and Justin Kerber founded it in fall 2021. The brewery also has ties to Newlin's history programs. On May 16, Succession brewers Sam Hollis and Keith Hartwig gave a historic brewing demonstration at the mill using reproduction 18th-century equipment and local ingredients.

Four October dates remain, according to Newlin's event schedule:

1. Oct. 8: Food by Wildings Events, music by Good Neighbor
2. Oct. 15: Food by The Munch Box, music by Christine Kinslow
3. Oct. 22: Food by The Munch Box
4. Oct. 29: Food by Wildings Events

Food vendors rotate, and Newlin's separate Happy Hours page lists Albie's Burgers for some of these same dates. Check the event page on the day before you plan dinner around a particular truck. Also, the beer is part of an organized event. Newlin's preserve rules ban alcoholic beverages otherwise, so don't bring your own.

The Organization Behind the Calendar

A site this busy during construction needs steady leadership, and Newlin has had changes there too. DELCO Today reported in December 2025 that Amy Ricci would become executive director in January. She came from Historic Rittenhouse Town. In June 2026, the Delaware County Daily Times reported that Newlin was among the organizations receiving Local Share Grant support for heritage-tourism improvements tied to the Brandywine Battlefield.

The year's events kept to their dates. The third annual Race for the Watershed Duck Derby & 5K was set for June 13 as a free-to-attend festival and fundraiser for protecting the watershed. The Fall Festival ran on Sept. 19, with demonstrations of historic trades, archaeology activities and local history groups. Admission was free, and parking was $10 per car.

Next is Tavern Night on Saturday, Nov. 7, an evening of 18th-century food, drink and music with two seatings. Tickets are $95 per person, and guests must be 21 or older. It falls nine days after the last October happy hour on Oct. 29.

Where the Mill Fits in the Rest of Glen Mills' Fall

Newlin is the anchor in Concord Township. Thornbury Township and the farm roads nearby fill in the rest of the season.

Sunday, Oct. 18, Thornbury Park. Thornbury Township's Halloween Parade, Fall Festival & Pie Baking Contest runs from 12:30 to 4 p.m. The parade forms at 12:30 at the Yellow House and steps off at 1 p.m. At the park there will be hot dogs and apple cider, coffee and cupcake trucks, a costume contest, a pumpkin patch and hay rides. Bring your own carving tools for pumpkin carving and your own clothes for scarecrow making. Pie judging starts at 2 p.m. in the Pavilion, with prizes for the top three. Bring copies of your recipe to share. The park itself is also mid-project. The township's Fall 2026 newsletter says a new maintenance building at the back of Thornbury Park should be finished by "the end of fall."

Weekends through Nov. 1, Arasapha Farm. The Harvest Hayride at 1835 Middletown Road runs on weekends from Sept. 19 to Nov. 1, with a corn maze, pumpkin picking and family activities. The farm's Bates Motel & Haunted Attractions run Oct. 2 through Nov. 1. Visit Delco notes that event changes may not reach its listings and recommends checking with organizers before you go.

On Baltimore Pike. One local restaurant changed this season. DELCO Today reported in late August that Testa Rossa had served its final customers at 919 Baltimore Pike, and no replacement tenant had been announced. Also on the Pike, Nudy's Café is open at 31 W. Baltimore Pike.

Here is the season on one calendar. Newlin's Thursdays run Oct. 8, 15, 22 and 29. Thornbury's parade is Sunday, Oct. 18. Arasapha's last hayride weekend ends Nov. 1. Tavern Night is Saturday, Nov. 7. A guided tour on any of those weekends will take you inside a mill whose new wheel is still being built by hand. Nobody has said when it will turn.
