Reading

Tsundoku

It means buying books and letting them pile up unread. The word dates back to the very beginning of modern Japan, the Meiji era (1868-1912) and has its origins in a pun. Tsundoku, which literally means reading pile, is written in Japanese as 積ん読.

Supporting Role

Center Stand

– I installed a component that should have been factory standard. But I got it for a deal and bolted it on mysen. Easier said than done that’s for sure… the access to some of the fasteners was colored by choice cursing.

Orbital Muscle

Rocketship

The new Triumph Rocket Three is a behemoth in person. And, it looks the part if escape velocity is your goal. 2 1/2 liters of beastly engine will propel this speed demon through the stratosphere. Chuck Yeager would be proud!

Heavy Fuel

Monster Truck | A couple of years ago Triumph USA toured their adventure bike Tiger models across the country using this heavy brute of a vehicle. Called the Atlak it drove from Atlanta to Alaska and parts between.

Man Cave

Winter Projects | with the oncoming off-season approaching I need to get the garage space organized. With limited space careful planning will ensure efficiency. A leaking roof needs to be addressed too.

Join us in our revolt Brother!

Factory Floor | journalistic photograph from the mid-seventies on the assembly line at Meriden. This was when the workers had a sit-in and production ground to a halt. A guttering flame.

Luddite not I

Technology | Now that we are well into the Twenty First Century everything gets fettled with Apps (applications). The Tiger being such a technologically inclined machine you can plug in your laptop with an ECU reader and delve into the program gubbins. Here the throttle bodies can be balanced – a far cry from balancing a pair of Amal carbs! Error codes checked, service intervals set, ABS brakes bleeding, sensor readings, instrument testing… it’s magical!

Woman Strong

Racer, metal fabricator, mechanic, TV personality Jessi Combs was killed while trying to push the envelope for a women’s speed record. She died tearing across a dry lake bed in Oregon in her rocket powered car at over 400mph. A strong talented person, she was an encouraging inspiration to girls and women nationwide. RIP Jessi Combs (1980-2019)

Pork

Bacon | Hogs can be other bikes too! Here’s a perfectly well engineered custom machine which has an adapted 3 cylinder Diesel engine that can be run on bacon grease. This was commissioned by Hormel Foods who make Spam.

Mirrored Moon

On Reflection | all photography releases by NASA shows how beautiful the ventures into space truly are. The LM Eagle reflecting the cratered surface is like a delicate Faberge egg balanced over a rugged plain.

Nosecone

Moonship Cutaway | beautiful technical illustration of the Command Module. The three astronauts traveled to the moon and back in the claustrophobic confines of this vessel. Though in zero-g it became very slightly more voluminous. They also had the Lunar Module which was docked to the nose of the LM for more elbow room. The CM is the only piece of hardware that made it back to earth.

Standing Room Only

LEM | Lunar (Excursion) Module. Three days after embarking on the Trans Lunar Injection the Apollo spacecraft entered orbit around the Moon. Separating from the Command Service Module the LM descended to the surface with the Commander and Pilot standing at these controls in their full spacesuits. The descent and landing is well documented as one of the coolest pieces of flying by anyone anywhere. Like landing a telephone box, using the computing power of a Casio scientific calculator, onto a grey dust surface under a black sky…. with diminishing fuel and alarms going off.

Apollo

Command Module | Fifty Years ago this month three intrepid explorers headed off into a lunar rendezvous with destiny. Backed by countless engineers, scientists, mathematicians, computers (women who crunches the complex equations for orbital mechanics), skilled laborers, wives, budget analysts, lingerie manufacturers (the space suits required impeccable needlework); they headed beyond the surly bonds of earth atop the mighty Saturn V rocket. The cramped confines of the Command Module ‘Columbia’ took them the quarter million miles to our closest neighbor in the skies.
