As your correspondent was walking home, a guy operating a drone above was in the street opposite a white sports car idling in the driving lane. Maki Hristo has a mobile car detailing business. Before he and his partner started cleaning and detailing the sports car in a nearby parking lot they were filming the car while it was still dirty with a drone-mounted 4K camera for their aerial “before” shots. Both the “before” and “after” will likely soon be presented among the slick music videos showcasing their detailing talents on Instagram and YouTube @MakiMotors Watch car detailers make movie with 4k drone camera
I finally got around to having my car's defective Takata airbag replaced and driving into the dealership, discovered that the service area had been completely renovated into a covered structure with multiple lances. Conicelli Honda in Conshohocken is one of the first in the nation to be equipped with new Hunter Engineering automated technology according to service advisor Russ Hauer. As explained by Hauer and demonstrated by Assistant Service Manager Marc Varallo, as you drive into the service area over a red plate, a laser in the device reads your tire tread depth. Simultaneously, a camera takes of a photo of your license plate; the system is tied in to the Pennsylvania Department of Transportation (PennDOT) and brings up your Vehicle Identification Number so there is no need to present your car registration for manual entry. A valet takes your car and you then walk inside the waiting area where a service agent greets you and promptly presents you with a graphic printout of the condition of your tires and whether a tire rotation or replacement are recommended.

Watch video and interview here. An operator high atop a pneumatic asphalt paver was assisted by two "back men" (otherwise called a screed or back end operators) at the rear of the machine on a little platform slightly above street level and by a crew of about 10 holding rakes, "lutes"and shovels laying down new street "mat" in northwest Philadelphia, Chestnut Hill. One back man who has been with the streets department since 1997 explained how this new half a million dollar computer-enabled paver is much superior to the 1996 model he originally worked with. He can monitor the job on a 7 inch display as the paver lays down what appears to be a couple inch thick layer of hot steaming asphalt and smoothly seam in a new section to an existing one, in automatic or manual mode turning the levels. It's important to regulate the speed, depth of material and and create a proper crown proper sloping down to the curb edge for rainwater to drain off. And a good back man, he says, makes less work for the foot crew who finish off the leveling work.
Ken Roberts of Kilian's Hardware Store gives a hands-on demonstration of the various snow shovels the store has leaning outside the store. There are ergonomic ones, some with bends in the handle, and another with a straight handle and an extra handle-mounted grip. Wide curved ones for clearing large areas of light snow. A narrower feed shovel type for digging out deeper snows without breaking your back. Steel edged blades for strength. Hard plastics and aluminum for lightness. Car shovels and, most useful of all kid-sized shovels. If you get the kids to shovel, you're halfway done, Roberts jokes. Watch demonstration here.
A generous school parent purchased a 3D printer for James Hilburt's math classes at the J. S. Jenks Middle School in the Chestnut Hill neighborhood of Philadelphia and Hilburt is getting the students excited about designing their own projects by printing out 3-d stackable cups, a rubik's cube-like 3d puzzle, a complete chess set and small replicas of the Disney Castle and the Eiffel Tower. To help the students understand design and construction, Hilburt is first having them build a bridge with Popsicle sticks. For the 3d printer projects, Hilburt downloads digital templates onto his computer and loads them into the printer; a rapidly moving arm lays down layer after layer of threadlike strands of melted plastic through a small nozzle head to build the creations from the ground up, taking nearly a day for the more complicated ones.

Dental hygienist Kara Hershey assiduously removes tartar from your correspondent's teeth while more than holding up her end of the conversation and guardedly discloses her ideas for inventions that she thinks could revolutionize dental care!
Kyle Gerckin, head of the caster department at Wendell August: American Made Gifts in Grove City, PA shows how to pour pewter into a custom-made mold to create an ornament. Next to its flagship store featuring hand-hammered metal gift items, the forge, in operation since 1923, is open to the public and offers tours. According to Gerckin, the pewter mixture Wendell August buys as ingots and melts down is composed of 90 percent tin, bismuth for its bonding properties, copper and a little bit of silver. The advantage of pewter, Gerckin says, is that it looks like silver but is less expensive and easy to work with.
Elizabeth Fink has been using the new composting toilets near the Wissahickon Environmental Center (formerly Andorra Tree House) at the northwestern edge of Fairmount Park, Philadelphia. It never smells, she says and there's Purell for hand sanitizing. She thinks it's a big improvement over the old "Johnn(ies) on the Spot". She's careful that her cell phone is in a zipped pocket, however, lest it inadvertently fall into the pit! She and a companion had been taking a walk in the woods and recommended I check out the toads mating in the pond above the tree house. Watch video here.
Your correspondent took his wife’s car to Dr. Ralph’s Automotive Services Center in Roxborough after she discovered one morning that it had been bashed overnight. While a technician was dusting off the last traces of the repair job, body shop manager John Klimowicz began explaining the business. While high strength steel is still used in car construction, thermoset plastics are becoming more common. To point out the strength of the repair work, Klimowicz relates that the same epoxies used to weld airplane panels are employed for car panel bonding repairs. If repaired properly, according to manufacturer specifications, “you can hit it with a sledge hammer and it will not break.” As to a future when driverless cars are expected to reduce collisions? “That remains to be seen.” In the meantime, Klimowicz believes there is plenty of work for Dr. Ralph’s and for the other nine or so car repair shops tightly spaced alongside this industrial stretch of Umbria Avenue.
