Age

Age. You forget things. That periodic table of elements I could merrily recite from memory down to the 60th element or so a few decades ago now sees me stuck at fifteen. Potassium, if I got that right.

And what with American liability law being what it is, with no one willing to accept responsibility for their actions, can you wonder about surgeons’ approach to tool management as a counterpoint to age? Each instrument is inventoried before and after the operation, in the hope that a scalpel, say, is not left inside the patient when he is sown up. I call this the ‘Surgeon’s Rule’.

This disciplined approach works every bit as well for this aging amateur mechanic, for while the risks are lower and the only person left to sue is yourself when you mess up, accounting for all your tools is no bad thing before exiting the hallowed workspace and flooring the throttle.



The wrench section on the peg board wall.

It is proper inventory management which has long seen me hang most of my tools from pegboards, believing that keeping them in drawers is exactly wrong. So forget those dreams of mega-buck SnapOn rolling tool chests. An utter waste of money. A tool you cannot see is a tool you mislay.

Further, those peg boards are white because not only are the stock brown ones depressing to contemplate, sucking light out of the workspace, white also sets the tools off nicely for ease of location.

The peg boards are attached to pine battens, the latter screwed into the wall studs behind the drywall, using a stud finder. That finder is like a politician, lying much of the time, but you get there eventually. The battens ensure that the whole thing is robust – tools can weigh a lot – and also provide offset from the wall for the hooks, once inserted.

Another dictate is that tools should never be stacked, as the one in the back will be every bit as lost as the one in that rolling cart’s tray. As the image shows I break this rule here and there, for lack of space, but overall it’s what you might style a solid effort.

That image speaks to a disciplined filing approach, if nothing else, yet the Surgeon’s Rule let me down the other day, because I failed to follow it. Check the red circle and there’s obviously a 19mm combination wrench missing. It is now to be found in one of my neighbors’ garages as it was left in place by yours truly when tightening the 19mm bolt on the crossbar which retains my old bike’s engine in the frame. I place one 19mm wrench on the left where it ‘locks’ against the exhaust pipe, then have at it on the other side to loosen the crossbar which allows the frame’s downtubes to separate ever so slightly, in turn making the oil filter cover accessible for removal. Not the greatest design by BMW, but not a big deal in the grand scheme of life.

I did not inventory my tools before riding around the neighborhood when the job was completed and later realized I had left the beautiful French Facom wrench in place when riding off. It fell off somewhere in the vicinity of my home and subsequent desperate searches (heck, any excuse for a ride) failed.

So I had to resort to this – mercifully Amazon stocks German Stahlwhille wrenches, if not the even more lovely French Facom ones:



The replacement.

So the rule here is to follow the Surgeon’s Rule religiously. And never, never, never buy cheap, imported tools. Real wrenches are made by Stahlwille and Facom. Yes, a few more dollars but a lifetime investment and one which will repay the premium paid every time you grasp that beautifully finished surface.

First ride – Fall 2020

The hibernation is over.

Unlike grizzlies, BMW Airhead motorcycles hibernate in the summer, when it’s too darned hot to leave a vintage machine in a 130F greenhouse passing as a garage, here in Scottsdale, Arizona.




Back on May 1, 2020.

So with temperatures finally dipping back into single figures, it was time to get the 1975 BMW R90/6 out of its refrigerated comfort zone and back on the road. Where it belongs.

The Odyssey gel cell battery needed no recharging, having dropped from 13.11 volts to 12.97 volts. On the other hand, the tubed tires did need air, each having lost some 50% of the usual 32/36 pounds in pressure. Easy. Oil? No need to check. German motorcycles do not leak.

So a gallon of high test later – the tank had been drained before indoor storage – a prod or two on the kick starter to get oil to the piston rings, full choke just for the start, a touch on the electric starter button to get that huge, antique Bosch lump of a starter to do its bit, and off we go. Kicking those big twin 450cc pistons into life from cold is no fun. Electric starting is the way to go, introduced in Airheads in 1970.

Nothing, but nothing, beats two motorized wheels.

Smooth that video

A new algorithm.

Back in the early days when founders Brin and Page were mere multi-millionaires, they concluded that it would be chic to adopt the catchy ‘Do no evil’ catchphrase for their company, Google. They then proceeded to do mighty evil on a global scale, stealing and reselling your identity, while maintaining that all their software was free. You, poor sap, were the product, to be sold and resold ad infinitum.

Now that Page and Brin are retired, needing the leisure time to count their ill-gotten billions, Google has actually gone and done something distinctly not evil. “Working with UC Merced and Shanghai Jiao Tong University (they) have detailed the development of DAIN, a depth-aware video frame interpolation algorithm that can seamlessly generate slow-motion videos from existing content without introducing excessive noise and unwanted artifacts.” (The quote is from DP Review).

This algorithm, and the related free software, allows interpolation of frames in low frame rate videos to restore smoothness. At the same time, the code is smart enough to properly treat overlapping and moving elements in the frame. The results are simply stunning, as this video from 1890s Paris – enhanced and colorized, as well as up-frame rated – shows:




Paris, 1890. Click for the video.

Wait a minute. Did I write that Google had momentarily given up its evil ways? Ooops! Now you can interpolate your cheating spouse into that video and, whammo!, a million dollar alimony settlement. Old habits die hard, I guess.

Rollie Free

Motorcyclist.

By any measure it’s the most famous motorcycling photograph ever.

Riding a lightly modified Vincent Black Lightning, a descendant of the iconic Black Shadow, putting out some 85hp from its 1000 cc V Twin motor, the wonderfully named Rollie Free (1900-1984) determined that his racing leathers were costing him speed on previous runs, where he maxed out at 147 mph. So he stripped down to bathing cap, trunks and sneakers and had at it, prone on the machine.




Bonneville, Utah, September 13, 1948. 150.313 mph. Protective gear optional.

Free’s record setting speed was on a machine which you could buy off the shelf. I would guess that the mufflers were removed and the Lightning had slightly hotter cams than the already fearsome Black Shadow.

The V Twin motor was known as ‘The Plumber’s Nightmare’, and you can see why:




Plumber’s nightmare. ‘HRD’ stands for Howard R. Davies, the founder of the Vincent factory.

Reminder, if any was needed, that there are two kinds of British motorcycles. Those that leak oil and those which will. But there was only one Rollie Free.

Restoring engraved lens markings

Easily done.

Back in the previous century when men were Men (and women were not Men) camera lenses were set in metal and distance, aperture and related markings were engraved and filled with contrasting paint. With age the paint either fades or falls out, making for a hard to use and unattractive tool. (Modern lenses use plastic, with awful screen printed numbers. Once these wear off you are stuck).




The $13,000 Leica Noctilux of today.
Yes, they still use paint in the engravings.

I have had this issue with Leica lenses and more recently with a tool in my garage, a low range Husky torque wrench which covers the 20-200 inch pound range (1.7 to 17 ft.lbs. or 2.3 to 23 Nm). The paint in the vernier markings on the rotating barrel had completely disappeared, testifying to years of use of this wonderful tool with low torque fasteners on those relatively soft alloy cases on BMW motorcycles. This made it very hard to set torque in the relatively low, non-directional light in the garage. Easily over-torqued, once you strip a female thread in one of these engine cases you are in a world of hurt. And that’s easily done without the proper tool. Forget doing it by ‘feel’. ‘Feel ‘ is for lovers, not mechanics.

The process of restoring those markings is simple.




The affected part is thoroughly degreased using isopropyl alcohol.


The fill in paint is generously applied in all directions.


The paint is wiped off with a rag, leaving filled in, engraved numbers.

Amazon carries the paint sticks in a variety of colors. Before use, be sure to shave the end off to reveal fresh paint, as the surface layer will have dried, and store the stick in an air-proof baggie to extend its useful life. And if torque wrenches are your thing, store them un-tensioned or prepare to deal with the consequences.
