Hell's Angels and Boy Scouts

Oh! Those wacky folks on the other side of the Atlanta Ocean.

I just found an article from June 16, 2010 about attacking Hell’s Angels with a puppy. Now I just finished a book on the Hell’s Angels and frankly siccing a puppy on them would not be my weapon of choice. Unless a puppy is what you call a baby dragon. http://www.telegraph.co.uk/news/worldnews/europe/germany/7830524/German-throws-puppy-at-Hells-Angels-bikers-then-flees-on-bulldozer.html


It turns out a German student, possibly with a death wish, mooned and then flung a puppy at a group of Hell’s Angels. He then tried to make his get away on a stolen bulldozer at 3 miles an hour. One can almost see the youth holding his pants up with one hand flogging away at the dozer with other hand, shout

“Faster!  Faster you fool. They are almost upon us!”

The paper didn’t report if he moved the dozer’s blade up and down in the menacing manner. The Telegraph reports he made good his get-a-way. He was later arrested at home. I can only surmise the Angel’s were laughing too hard to chase after him.

Last September Great Britain’s Boy Scouts were advised not to carry their pen knives, even when in uniform. An English newspaper, The Guardian, reports that “Scouts are so closely associated with pocket knives that the term Boy Scout knife is a synonym for penknife.” Bad news from the nation that once carved out an empire so bold, so large, the sun never set on it and is now afraid of Boy Scouts. It must have been that deadly combination of folding blade and can opener that was more than anyone could take.

In a related story, it was reported the whirring noise reported by so many Britons was identified as Lord Baden-Powell spinning in his grave. http://en.wikipedia.org/wiki/Robert_Baden-Powell,_1st_Baron_Baden-Powell

April Showers And All That Jazz

“April showers bring May flowers that bloom in June...” singers croon, but we know they bring grass. Healthy, tall growing, vibrant, green grass that has to be cut on a regular basis.

I popped off the blade on my grass cutter to give it a much needed sharpening. I’m always amazed by rotary mower blades, only the tips are sharp. I always thought they would be more effective if the entire blade was razor sharp.

Not so, grass cutter man. Only the tips of the blade need to be sharpened. More on that later.

I use to take my blade into a mower shop where I envisioned a skilled certified technician (in a white lab coat, of course) who would carefully grind and polish the blade with a set of water cooled stones at some precise angle dictated by the blade manufacture. Careful to take only an equal amount of metal from both blade ends, he would constantly check the blade’s balance so it will spin true.

Not so, grass cutter man. Some guy eyeballs the edge while passing it over the course grind wheel. Sparks shoot out the back of the grinder and maybe he makes a second pass to see more sparks if he missed the fireworks last 4th of July.

I hate it when reality collides with my imagination! So I bought a disk-shaped stone with a plastic collar/guide that fits my cordless drill and now I just clap the blade in a vice and grind it myself. Then when I’m done, I can use a fine carbide stone to polish up the rough spots.

I was thinking while clamping it in the vice, how fast does the edge move? I took a measurement from the blade axle center to the leading and trailing edge. The back of the blade is 4.5 inches from the center while the leading edge is 9.5 inches. Since the blade spins at 3600 rpm that means the blade is spinning at, ahh, let’s see, 3.1415 times 0.375, carry the 7…

Wow, the front of the blade zips along at 101 miles per hour while the back of the blade is loafing along at a measly 48 miles per hour. The blade is only five inches long, so if I’m mowing an inch a second, (as a trivial exercise to the reader I let you calculate how fast I’m walking), a one inch section of the blade spins 60 revolutions over that one inch of grass.

Speaking for myself, cutting grass has a new dimension of fun!

On the Road from Atlanta

The Monday after the Blade Show was a travel day. As predicted by Nostradamus on my last blog entry, it was a long day.
On behalf of 100,000 drivers I want to acknowledge and thank the unofficial pit-stop of America. They are clean, well lit and air-conditioned. Thanks McDonalds! I never would have made it home without you.

Some people think trips are fueled by gasoline. My trip home was fueled by McDonald’s iced-coffees!

Now comes the work of filing all the literature, business cards and notes for future blogs. My parting lines come from the music world, but pertain to knives and many aspects of daily life: C sharp or B flat.
