Hammerhead Stoneworks

A couple of weekends ago, I led a workshop at the NC Arboretum on building stone benches. First thing in the morning we studied images of various benches, stone-cutting techniques and ways to move heavy objects safely and with relative ease. Safety was a recurring theme throughout the day. After the classroom presentation, we went outside and built a free-standing bench, a style I call castle-block for the big chunks of stone that make up the supports. The bench we built is now a permanent fixture at the Arboretum, a rest station along one of the trails.

To facilitate ease of movement, we cut the big stone down in the back of my truck. In this image, Ronnie is using a star bit chisel to notch shallow guide holes in the top of the stone. This gives the drill bit a place to sit, reducing the likelihood of the bit bouncing around and scarring the stone.

Everyone got a chance to use the drill and work at cutting stone. Here Judy leans into the drill to get the proper placement.

Since our cut edges were going to be exposed, we took some time to clean up the drill holes. Here Carol is using a handset chisel to knock off the cut edge of the bench stone. We put the cut edge to the back of the bench, less visible to passers-by.

We spent some time doing bench math, designing everything so that it would be the proper height and balanced as a structure and as an aesthetic object. Here Carol measures the thickness of the slab, the starting point for figuring out the math. I handed out the following worksheet to guide the design and layout process.

By cutting it in the back of truck, we made the stone more manageable, but it was still a heavy chunk. Jason uses a rock bar to move the stone from the pallet onto the ramps we have set up. Using 2″ by 12″ pressured treated lumber as ramps, we slid the stone down to waiting blocks and from there into place.

We used mortar to set the bench. This design can be done dry, but the mortar reduces the risk of movement, particularly since the bench is in a public place.

We all felt good as we finished up. The bench looked great and we had built it efficiently and safely. It felt good to be leaving something cool and useful for everyone to enjoy. Tre and Ronnie test drive the bench and pronounce it good.

My friend Matthew in Chapel Hill sent me this image recently of Grandpa Tony’s memorial bench surrounded by spring time flowers. He mentioned that some neighborhood kids circulated a flyer announcing a lemonade and cookie sale at Grandpa Tony’s bench, suggesting it’s already become part of the character of the place. That’s always gratifying to hear.

On May 15th I’ll be leading a workshop at the Arboretum on making a stone bench similar to Tony’s.

I am starting my class prep for the Stonework Special Projects: Making A Bench session at the North Carolina Arboretum in May. Here’s a section of the slideshow focusing on making a bench in a drystone retaining wall.

The new class schedule for the North Carolina Arboretum was recently announced. I am leading three stonework classes this spring. DIY Flagstone Paths & Patios will be offered twice, on Saturday April 10th and on Friday April 16th. In the morning session, we discuss the basics of drystone flagging: necessary site prep, the principles of good structure and varying joinery styles. In the afternoon we go outside to the stone classroom and practice the essential skills: moving stone safely, shaping individual pieces and leveling the patio.

I am offering a brand new class this spring, called Stonework Special Projects: Making a Bench on Saturday May 15th. In the morning we will discuss the design and structural issues of building a stone bench. In the afternoon we will build a freestanding bench ourselves. Topics of note including cutting stone with feathers and wedges and how to move large stones safely.

Register via the Arboretum’s on-line calendar.

I just added a new portfolio page about the recently completed dentist wall and bench. The image above links to the page. On the page itself, the same image links to a monster panorama.

We got about a foot of snow on Friday. Click the above image for a huge view.

CHAPEL HILL – When Grandpa Tony went out for his walks, which he did nearly every day until he was into his mid-90s, he always made sure he was well provisioned.
He kept cookies in his right pocket for the neighborhood’s children and dog treats dogs in his left pocket for its dogs. For everyone he had a smile, a wave and a warm conversation.
“He lived here for 18 years and he walked miles every day,” said Virginia Saam, one of Antonio Marimpietri’s neighbors in the Ironwoods subdivison off Seawell School Road. “He talked to everybody. He knew all the kids. He knew all the dogs. Everybody knew Grandpa Tony.”
And when Marimpietri died last July, a month after his 98th birthday, everybody felt the loss. As word of his passing spread, in person and through the Ironwoods blog, the sentiment quickly grew that the neighborhood should commemorate his life and vibrant presence in some way.
“There’s a corner in the neighborhood where the road splits, and Tony would always sit on his walker at that corner and wave and talk to everyone who passed by,” Saam said. “It sort of became Tony’s corner. It occurred to me that maybe we could do something special for him there. That got such a response! Everybody wanted to contribute.”
Another neighbor, Deb Vacca, suggested that it would be a fitting tribute to remember Grandpa Tony with a bench at his corner, a resting place where neighbors could stop and visit with one another just as he always had.
“We settled on the idea of a stone bench, and then we did a Google search,” said neighbor Matthew Feldt. “We found a stonemason based in Asheville. He turned out to be exactly what we were looking for — somebody who is eco-centric, detail oriented, somebody who would really care about the project. And he did; he came to care about Tony.”
Marc Archambault makes exquisite natural stone walls, patios, walkways and other projects, using “dry,” or mortar-free techniques. He does most of his work in and around Asheville, but “for the right project,” he says, he’ll go just about anywhere. Grandpa Tony’s bench was a right project.
Archambault cut the 600-pound bench slab from a 3,000-pound block of Tennessee sandstone. He chiseled the support pedestals from smaller — though still substantial — blocks of stone, and on Oct. 30 he brought the whole thing down from the mountains in a pickup truck. With Feldt’s help, he unloaded the slab, prepared and leveled the site and constructed the bench. On a separate block he affixed a plaque reading, “For our friend, Grandpa Tony Marimpietri.” He covered the bench and block with a tarp so the epoxy holding the plaque in place could dry for 24 hours.
The next day was Halloween, when the neighborhood every year holds a potluck part. On an impulse, Ironwoods resident Ginny Thompson sent an e-mail out proposing to unveil the bench before the potluck.
“I sent out this note and went and bought a couple bottles of wine,” Thompson said. “I only gave everybody about two hours’ notice, so I didn’t expect much turnout. I figured, worst case scenario, I’d have a glass of wine with a neighbor.”
She should have bought more wine. Despite the short notice, more than 20 residents showed up, along, of course, with lots of kids and dogs.
Vince Norako, a good friend of Grandpa Tony’s, offered an eloquent toast, and Marimpietri’s son Tony, who lives with his family in Ironwoods, pulled the tarp off the bench.
“It meant a lot,” Tony Marimpietri said. “The neighborhood has been amazing.”
His father, he said, grew up in New York and worked in the restaurant business — “He said that during the Depression if you worked in a restaurant, at least you could eat,” he said.
Marimpietri the elder opened two restaurants of his own in New Jersey and eventually moved into the wine business, becoming a sommelier. He moved to Ironwoods in 1991 and immediately began to make friends.
“Dad was very gregarious, and people responded to him because he was authentic, because he was legitimately interested in them and their lives,” Tony Marimpietri said. “He always stopped to talk, and people were always visiting him at his home. They would take him to the store or to his favorite restaurant, Italian Pizzeria III. As he was going through the dying process, so many people went to Hospice to visit with him and say goodbye. The people at Hospice told me they’d never seen anything like it.
“Everyone was very, very supportive. They say it takes a village to raise a child. Well, it takes a village to care for the elderly, too.”

I’ve just added a page about the Eight Leaves, Nine Stories patio pictured above. Click the image to explore the creation of the patio.

This looks more like a crime scene than job site. I set up lights to work later on Monday, talking advantage of the lovely weather. Today’s nasty rain and tomorrow’s threat of wind gusts up 55 mph makes me glad I did.

These two benches were cut from the same slab of Tennessee sandstone. The first was built as a free-standing structure in a Chapel Hill neighborhood to celebrate the life of one of their most beloved members, Grandpa Tony. The bench is mortared and features an adjacent boulder with a small plaque. I call this type a castle block bench, named after the material used for the base stones. The second bench is in Asheville, adjacent to a sidewalk. The sitting stone, seatback and arm rests were all cut from same stone as Grandpa Tony’s bench. It is a drystone structure and built directly into the retaining wall.
Next spring I will be leading a hands-on class at the Arboretum on making a stone bench. We’ll be building a castle block bench together that day. The official class date hasn’t been announced, but let me know if you’d like to be updated when the class registry opens.
