The Sticks

places, social

A 1971 USDA historical aerial photo from UNC Chapel Hill libraries showing the neighborhood now known as Charleston Woods. Before the houses were built, Charleston Woods was actual woods! The point location was determined by taking angles from the Bond Lake Dam (under construction), the White Oak Creek and a transmission line which transits. It is a general estimate.

There are also aerial photographs of the county from 1959 and 1938 that also show pine and hardwoods here. The farmland fields that are present in these images are limited to low flat areas of Crabtree Creek; what is now Bond Park Baseball Diamonds 5 & 6 and the Prestonwood Soccer Complex northward. The survey depicts rail tracks and 2 public roads that precede these dates — Highhouse Rd. and Old Apex Rd. None of the streets that we enjoy today had been built yet. The actual full resolution photo file taken on February 24, 1971 can be retrieved easily from here.

The same perspective (via satellite and incolor) today!

After measuring the [29″] diameter of a particularly large Loblolly Pine in the backyard it can be assumed that the area has not been recently cultivated. A 36″ tree is considered mature and that size equates to about 150 years age. There have been people in the area since before the Civil War so it is of course possible that the area had been logged, farmed, or burned. The 1938 shows faint trace remnants of bare dirt that may have been encroaching trails. These are no longer noticeable in subsequent surveys.

Developers had there way made progress and this area has forever lost its out in the sticks nature. It would have been easier to clear cut but to their credit many of the trees were spared.

Update: (according to this source) Before the first Europeans set foot on the [North Carolina] Piedmont Plateau, the land was 99.5% covered by Old Growth forest (oaks, maples, pines, hickories, poplar and tulip poplar, persimmon, elm, hemlock, beech, magnolia, cedar, ash, willow). Some scholars write that the Old Growth was harvested entirely by 1750. All agree that these magnificent trees had been taken down by the start of the Revolutionary War in 1776. When the Old Growth was gone, they started in on the secondary growth. This greatly over-simplified history explains the proliferation of fast-growing pine trees common today.

Beneteau San Juans

adventure, boats

It was a Beneteau Oceanis 381 with a layout similar to last years except below deck was a flip flop opposite. Only one quarter berth which was a full. Larger V berth forward. Diesel forced air heater which we used a couple of times. Chilly until noon. Sunny afternoons. Never rained. The AYC yachts are individually owned and you could tell that our boat was looked after.

Big galley with two refrigerators. Propane BBQ. Galley stove oven had a broiler.

Smaller Lav space (as if that was even possible). The holding tank was a mere 15 !! gallons and with strict eco regs in US waters that meant we really had to watch it. I had the pleasure of pumping it out twice. Well, pump-outs are encouraged by being free anyway.

We anchored out once. Picked up a ball at two other stops. BTW, you taught Spencer well on the fore-deck He was invaluable. Leah was a complete noobe on day one but by mid week she had it down and by voyage end had the sailing bug. Stayed on a linear mooring one night and one night on a dock. Also, we had to put our own boat in its slip back in Anacortes. No such thing as a marina skipper.

Cleared Canadian / US customs which was good experience. Navigation fairly easy with the GPS tracking and land ho. Fewer visual cues on the long sail to and from Victoria in which case it was GPS track and DR

I kept a watchful eye on tides and currents. We traversed a few tidal current rips but those were a non event. We had to be careful for floating logs. We saw several. Man that would have made a big noise to collide. Remind me not to sail there at night. Big container ships in the lanes too. The most current was 2.5 knots which didn’t last long and luckily was going our way.

The most wind that we saw was 16 knots at which full sail was slightly over powered close hauled. The main sail could be furled into the mast. Very trick. 1 to 2 foot wind waves at times. For the most part the wind was 6 to 10 knots. The ride was always good. Our charter had Radar with AIS if we’d have been caught out by fog but we were only concerned once and it turned out not to be a factor.

Like Father like son, Spencer almost did an endo off of the transom but fell into the dinghy instead. Whew!

53 degrees. I was concerned about going overboard while underway and nobody noticing right away. That would have been bad scene.

Ace – photo detective

cars

From Aunt Jayne’s dusty family archive comes this forgotten 1910 photograph of a first car in Iowa…

somewhere in Iowa…

What car is it? A major clue is the marque logo on the facade. Star Cars. The emblem, while somewhat faded, is a match from the Durant Motors Company, manufacturer of.

Model C Runabout

A 1923 Star Runabout roadster is an obvious preliminary guess but this automobile using a catalog picture above is not a match for Pop and Mom’s car. Here is a better one:

The trunk bustle has a reverse sweeping curve up to the convertible top whereas the Star (above) maintains a constant arc to a level body top edge line. The side by side cars are much sportier looking especially with the rakish mountable spare tire. The visual comparison on the right is a [1918-] 1923 Dodge Standard A Roadster. Tell me if you think it a ringer for our original car on the left…

As usual more questions than answers. Grandpa’s first car is showing some age so perhaps the photo was snapped sometime after the mid ’20s. There isn’t a numbered registration plate on the bumper. The place looks closed; out on a Sunday drive? They could have acquired their car from the Star Cars Auto Repairing or had it serviced there however It seems an unlikely photo venue.

We are on the wrong track. The object of the photo is quite possibly of the building or property itself which just happens to include a random car in the foreground. The original photoshoot could not happen before 1922 because this was the inception of the Durant Company’s Star Car. Based on the weathered appearance of the paint logo on the building face, I’d have to say that it was a least a few years further along.

This car pictured, having no backseat, would have been suitable for 2 or 3 but hardly large enough to be used as a family car. I count Grandpa, Grandma plus 4 children by that time. A roadster would have been impractical and the folks in Iowa were a sensible and pragmatic sort.

Here’s what we know: The caption date of 1910 is bogus and we are pretty certain that the car is not a Star; furthermore we are not swayed by claims of the featured car’s provenance. The significance of the building we have yet to learn. My Aunt’s pen & ink caption is fantastical — or is it…

Benz-Jewelry

cars

A broader flattened and padded safety hub was introduced with the 1959 W111 ‘fintail’ model. This engineering effort was years ahead of other makes. The padding may have been a false sense of security but the expanse would improve chances in case of accidental impact. Previous hubs were decorative and could be pointy (harpoon spear shaped).

Donor hub

Serving its purpose for years after having been liberated from Dad’s 1967 200 D (W110) which was pretty used up, I’m certain that this relic piece survived the car. It now lives on the shelf having been replaced with a reproduction part that is a near match to the original ivory one.

The wheel rim has stress cracks so it too will have to be restored at some point but Mercedes bling is like jewelry $$$. So, methodical pace.

These early cars had primitive seatbelts (if that) so any passive protection from the steering wheel is appreciated.

Hood Hinge Procrastination

cars,

I’d released the counter springs on the hinges decades ago and so the hood would no longer hold itself up; not without a prop rod. The springs were tensioned to their weakest setting and I knew not how to increase it. Tools on hand at the time were a pair of vice grips with bailing wire; good enough to release a spring but clumsy. Coil springs have stored energy and can cause injury when mishandled. Uncertain about how to [properly] go about it and a bit apprehensive the job was put off. Fast Forward today to the Internet Age; a Youtube hit gave inspiration.

If the springs could be extended and placed in the hinge’s more extreme setting slot then the increased force under tension would correctly balance the open hood. Unfortunately, the size of each individual spring (one per hinge) was such that mere muscle power would not overcome the difficult flexing required to get that job done. Leverage was needed.

rope line loop used to coax the spring

A couple of Ratchet Tie-Down Trailer Straps provided the persuasion. An concrete post in the garage floor lent an immovable anchor point. A second strap maintained a proper pull angle since the post was off center.

ratchets serve as a Come Along

The ratchet acting as a winch provided the grunt and the ear of the spring was positioned adjacent to its proper location. With care and finesse the spring could then be hooked over the tang and into the correct slot on the hinge mount.

I have to give thumbs-up acknowledgement to the Youtuber DIY; he sure made it look easy. Well, it’s never easy but a least now finally — no more prop rod! A bucket list project perceived as insurmountable all these years gets resolved.

Student Driver

cars

Trust (but verify)

Self driving cars are a few years away. Letting Autopilot take control is like watching an inexperienced beginner on a learner permit. Fortunately, as a monitor (with skin at stake) you can gently intervene or abruptly take-over if the performance is not to one’s liking.

Current state of the art tech with Hardware 2.5 does quite the job centering the vehicle in the lane and maintaining proper distance from the car ahead with adaptive speed. Today, on an extended drive, I was able to sample test the latest enhancement: Navigate on Autopilot (beta) which further extends Autopilot.

Following GPS guidance Navigate on Autopilot suggests lane changes required for the route. Using cameras and forward radar it also recommends an open lane when overtaking a slower vehicle. You, as second pilot, acknowledge the suggestion and give permission with a tap on either stalk on the steering column (ignore is the default). In actuality you are babysitting the proceedings — and like a hawk.

There isn’t, nor should there be any trust expectation between you and the machine. The manufacturer (and his lawyer) feels the same way. Beyond any disclaimer you need to be attentive. The reason is called the automation hand-over. The autopilot can, after the briefest of warning, signal bailout and return control. If your head is not in the game this transfer could be messy. So, autopilot continually confirms that you are standing by. If you’re not detected actually holding the steering wheel you are politely prodded before it becomes serious. The system shuts off / locks out an abuser ignoring any cautionary nags.

Proper technique: the weight and friction from one hand is sufficient to apply “slight turning pressure” which is the assurance that Autopilot is looking for

The autosteer function continually saws back and forth ever so minutely seemingly testing to see that it has not been abandoned. A sensitive passenger may perceive the motion but in comparison to earlier iterations it is fairly smooth going.

Hardware 1.0 was primitive as autosteer would ping pong on secondary roadways hugging the inside line or wandering inebriated opposite. Still, it was exciting to experience this alpha software. Realizing that the future had arrived inspired anticipation for FSD

Lane keeping on today’s trip was quite good during the Interstate portion. There were some, shades of yore, one spurious blip of regen, a wander noted in the tight radii of an exit ramp. A little faith was required but no boundaries were exceeded. I did wonder what any closely following driver might be thinking.

whoa boy (too wild)

This happened… A mowing tractor pedaling the shoulder as fast as he could go — hazard flashers blinking but protruding somewhat into the right lane. Autopilot decelerated for the detected obstacle as it should do. I switched off auto steering and moved to the left lane to pass which was occupied by a truck just ahead. During the maneuver, just as I started over Autopilot saw daylight between Mower and Truck and (adaptive cruise control still engaged) accelerated harshly. Splitting lanes like some deathwish motorcyclist would have been a bit too sporty.

push nudge (too timid)

Autopilot slows as necessary for a vehicle ahead which is turning right onto a crossroad. Ordinarily, a driver can safely resume speed accelerating in anticipation of the other vehicle clearing. Autopilot delays this for a count of 3 before getting on with it. It seems like an eternity because know that the driver(s) behind have lost patience.

advanced nav (passed)

One part of the route today is considered tricky even for an experienced operator. I have traversed it many times and decided to let the student driver have a go. The course begins with an off ramp exit, followed by a double merge, another exit, a sweeping loop where traffic sometimes can crawl or even halt, and then yet another merge — all rapid fire. Autopilot has to steer navigate and sequence with the merging vehicles. It’s the full deal. Tight choreography. Autopilot will slow to make a merge opportunity happen but doesn’t offensively overtake for a cut-in. 

As blue traffic autopilot performed a weave merge with cyan traffic. Green dots depict where autopilot asks permission to exit route leg or for the navigational lane changes.

Eventually cars will computer interface with each other and the dance sequence will be safe and carefree. Until then, it’s student learning so; mind how you go. It’s early days yet.

Ponton Door Sill Restoration

cars,

Old cars had running boards. A vestige from this bygone era, the modern car door sill is nothing more than a decorative piece to prevent one’s shoes from scuffing the body painted entry threshold. This plate is likely to be of plastic assembly with the make or logo embossed. On the exterior side is the tarmac and the other side is the carpet. When shut the door covers the sill plate.

The door sill/scuff plate on ‘Ponton‘ era Mercedes-Benz were not that far removed from the old running boards. They could be described as internal running boards as they were enveloped by body when the closed door overlapped them. They are really not wide enough to stand upon nor were they so intended but there they are welcoming gateway to driver and passenger. From the illustration below observe that the vertical chrome trim plate and an aluminium surround piece serves to offer scuff protection. The flat sill spans between them.

perished mat

The original rubber sill (above) is aged and brittle. It has seen better days. The refurbishment project was initiated some years back (pre-internet) where it stalled due to non-availability of replacement parts. Recently, I began the search anew. The problem is that there is no longer much demand for this style ribbed rubber material. What I could find was in black only or some egregious industrial offering. The pursuit picked up when I found “grey mat for Mercedes”. ‘Imported’ from the limited description sounded promising but the bulk size and color were not and were likely for some later model.

new mat in place

Finally, success! An outfit in Germany called Niemöller Ersatzteile für Mercedes-Benz Veteranen seemed to have what I sought. I ordered their self-described hellbeige ribbed rubber with high expectations and was not let down. The material was rolled in bulk so a paper template had to be drawn and the mat trimmed. The new piece was cemented down after the fasteners removed and the shiny bits cleared for access.

Factory labor intensive, I counted 15 individual screws for each door entry (for which holes also had to be drilled). I don’t suppose that they had bots or even electric screwdrivers to speed that process. A contrast in manufacturing technique, today’s sill plate application must take the assembly line person mere seconds to snap in to place.

Headlight Cover Restoration

cars

Full disclosure: The Before picture was taken indoors whereas the After is using natural light, thus the paint color variation.

Opaque / Clear

The Zuffenhausen factory specified a tough clear UV protective coating which has performed well for the past 13 years of exposure. However it’s a tough environment and these lense covers are only plastic afterall.

A polishing kit from 3M was purchased to rejuvenate the current cloudy finish. Using my low speed electric drill, the supplied buffer wheel attachment and abrasive media, pits and scratches were incrementally removed. I deviated from the prescribed and used some 320 grit to begin with. This made quick work of the original factory coating, totally removing it. Naked uncoated, stages of number 500, 800, 3000 (wet) progressed. Finally the kit included a liquid rubbing compound that completed the goal of clarity. The surface is now quite smooth.

Routine application of a formulated polish with water resistant polymers such as PlastX or toothpaste (!) should offer protection from this point onward.

Short Trip

boats

What was meant to be a grand outing, taking family on a Saturday sailboat ride turned out to be a “3 hour tour” instead. No not island shipwrecked; we all returned to the dock intact — but not before an encounter with a dredger train of barges, a soft grounding, a crab pot entanglement, engine breakdown, 2 rescue tows and a mangled boat hook! It was a chain of events. One thing upon another, and then another and then…

It’s never opportune timing to have mechanical failure but in this case we were very close to home. However, the marina is tight quarters and their rules forbid maneuvering under sail anyway. So we got professionally alongside towed on the hip. Here was the culprit:

Riser – ruptures after years in service

I found that this is actually a common failure. It is unsuspecting before it happens because the heavy iron casting rusts from the inside. There may be light surface corrosion on the outside or even shiny paint hiding what lurks. (A prudent Sailor will think to change this part out before it expires.) The failure symptom was a marked change in engine tone. Raising the hood revealed noxious black fumes and water pumping into the bilge. Gnarly.

The exhaust mixing elbow (aka Riser) is a short length special pipe between the engine manifold and the heavy black hose clamped on the lower end. Hot gasses are joined with cooling water and delivered under pressure of combustion toward being muffled and
properly discharged overboard.

Spiffy Replacement

This new custom fabrication is stainless steel and will give good endurance. Should be good to go! I only need now to convince my guests to come along and try boating again. Please come back!
