Last Friday I led an hour long workshop for craftspeople and artisans on how to market their work. It was part of Handmade in America’s Art, Craft and Design Expo at the North Carolina Arboretum. The main push of my talk was that marketing is education and that craft artists should focus their marketing efforts on the 3 P’s: product, process and person. I also talked a bit about setting goals, making a cohesive plan and punk rock.

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.

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 picked up my first T-shirts. They are white Gildan brand with this design on the chest. I have a few extra so if you are interested in acquiring one, send me a note and please include your size. Gildan brand tend to run large. I’m going to sell them for 15USD, shipping included to the continental United States. Shipping elsewhere will cost more. We can swap shirts too, if you’ve got something cool.

Benches abound in my work right now, which is good timing. I’m documenting the process in great detail preparing for my first bench-making class next spring at the Arboretum.

I drew the line over a few times, trying to get the right shape. I wanted a subtle curve, figuring it would be easier to accomplish. The X’s indicate where the drill holes be, evenly spaced. This is the back of the stone, so my scribbles and drill marks will be unseen.

I drilled six holes. Why six? Because that’s how many complete sets of feathers and wedges I had at the time. More would have been better. The holes are fairly shallow, about two inches. The stone itself is only three inches thick. I was careful to not punch the drill bit through the stone, as it would have created ugly knockouts.

I placed the wedges so that they turned along the line. This ensures that the force applied pushed the stone apart along the desired line. They look like soldiers marching.

Ah, so close. The actual split wandered from the desired line at the very bottom of the stone. Looking at it now, it’s clear that the split followed the path of least resistance. Another wedge even closer to the edge might have helped this, as would have reorienting the line so that the desired line followed the path of least resistance. Tracing the desired line with a chisel might also have been helpful.
There’s a lot of surface flaking where the feathers are set. I believe the wedges are a fraction to big for the drill holes so that they bind at the top and cause the stone to pop like this. This was a secondhand set of wedges that I have since replaced. Another reason to do this on the bottom of the stone.

Here are the cut stones in the pathway. The two big, rust-colored stones to the left side of the image are the cut stones flipped and set. Note the ‘dog paw’ pebbling just above the gray stone, to honor Dixie, a regular visitor to my lunches during the project.
