How to Prepare Stock for Joinery | Paul Sellers
Published on 23 Jun 2017
What do you need to do to your dimensioned wood to prepare it for joinery? Often there are undulations or machine marks in the surface of the wood, or movement after dimensioning that needs removing before joinery layout occurs. Let’s work on getting the silky smooth surface and square faces that make for crisp, accurate joinery.

Helicopters Won’t Just Drop Like A Rock If The Engine Dies
Published on 6 Jun 2016
Autorotation in action: https://www.youtube.com/watch?v=pzWw5U3eCok
In this video:
In fact, you have a better chance at surviving in a helicopter when the engine fails than you do in an airplane. Helicopters are designed specifically to allow pilots to have a reasonable chance of landing them safely in the case where the engine stops working during flight, often with no damage at all. They accomplish this via autorotation of the main rotor blades.

Handsaw comparison – Japanese pull-cut versus Western push-cut
On Facebook, Paul Sellers posted a couple of photos showing the differences between some traditional western hand saws, which cut on the push stroke, and traditional Japanese hand saws, which cut on the pull stroke:
When you hear people say Japanese saws cut better, cut cleaner, cut faster, cut easier, usually it’s not necessarily true. In reality the Japanese saws cut on a pull stroke and the western saw on a push. When sharpened properly both cut very well. The difference for me is that one is a throwaway, the other a keeper for a lifetime. I own saws made in England and the USA that are totally functional and range in age from between the early 1800s 1860s and some up to date that I use daily. You can make any saw any thickness you like and it will work well.
Just saying.The main difference nowadays is you throw away the Japanese saws because you can’t sharpen them whereas a decent western saw can be sharpened, well, for 200 years when you learn how. Most people can master saw sharpening with an hour of practice.

Sometimes, the workman is right to blame his tools
Paul Sellers recently bought and tested a new Two Cherries brand “Gent’s saw” and was very unhappy with the tool:
This week I picked up a brand new gent’s saw straight from the pack made by the famous German tool makers Two Cherries. I noticed the unusual tooth shape, which strangely resembled the edge of a tin can when we used to open it with a multipurpose survival knife. I wondered how it would work and whether it was just a miscut. I examined several others and realised it was actually intentional as they were indeed manufactured that way. I offered the saw to the wood and the very middle cut with the dovetailed angle and the broken off section was the results of ten strokes.
“The long saw cut on the left is how the saw cuts by a man who has used such saws every day, six days a week for 53 years. The two to the right are how it cuts after sharpening and redefining the teeth.”
Could this truly be the end product of the once highly acclaimed Two Cherries of German tool manufacturing? I looked at the packet and, well, there it was; Made in Germany. So here is my perspective on the saw. Nice beechwood handle–nicely shaped (but it is unfinished), nice brass back, good quality steel plate, not too soft, not too hard. Two Cherries, the materials leave you no excuse for making such a poor grade product. YOU should be very ASHAMED of your product and yourselves. It is the very worst saw of any and all saws ever, ever, ever manufactured. I have never seen anything worse.
[…]
If you bought this saw and you thought the outcome was a result of your inexperience. It’s not. Blame the tool maker. It’s his pure arrogance to think he can pass something off to you like this and call it a dovetail saw. Shame on you Two Cherries, shame on you!

What You Need to Know About Glue | WOODWORKING BASICS
Published on 22 Apr 2016
Gluing is an essential part of woodworking. Here are the basics to get you started. Please read the full article for more info ►► http://bit.ly/Gluing
Near the end of the video, he mentions the glue I’ve been using pretty much exclusively since I got started in woodworking: Weldbond. It works as well as he says, and as a result, I don’t have much experience using other glues for woodworking projects.

The “killer app of space tourism”
The “mile-high club” will soon be replaced by the “sixty-two-mile-high club“, says Glamour in their coverage of “Sex in Space“:
As Elon Musk announces a plan to start colonizing Mars in 2020 and space tourism companies begin offering (very pricey) trips outside the planet, space vacation is suddenly looking less like a sci-fi plot and more like a real possibility. And like any other type of vacation, one of the best parts will probably be sex. But sex in space? Is that even a thing?
To our knowledge, no one’s boldly gone there, but that hasn’t stopped the experts from guessing. Here, they answer some of our most pressing questions about the future of hooking up in space.
Is it even possible?
Sure, though keep in mind that in space capsule conditions, there’ll be considerably more fumbling around. Just getting our parts to touch could be a puzzle, since it turns out gravity is the important sex aid you didn’t even realize you were using.
“Because successful coitus for humans relies on gravity to achieve correct alignment and maintain contact with the participants’ genitals, its absence will pose a novel problem,” says OBGYN Kyrin Dunston, MD. “In addition, the thrusting motions required for successful coitus will present unique reactions in the female, where she will be propelled away from her partner during coitus, making the act very difficult.” (Though it’s pretty hilarious to picture.)
According to Dr. John Millis, Ph.D, a physicist and astronomer at Anderson University, it would be almost like two ice skaters pushing their hands against each other while standing on ice. “This two-dimensional example is complicated further by the fact that, in space, the astronauts would be moving in three-dimensions,” he says.
Will we need a whole new genre of sex toys, then?
If we want to streamline space sex, we may have to enlist technology to stop people from floating away from each other. A good space-sex device would have to attach the astronauts to their partners and the space station, says Millis.
Dr. Dunston elaborates: “That could be a jungle gym-type apparatus that allows people to position themselves appropriately to a strap system that holds them together, or clothing that accomplishes the same thing. Imaginative minds will create something ingenious, I’m sure.”

Tank Chats #10 Crossley Chevrolet Armoured Car
Published on 19 Oct 2015
Armoured cars had proved so successful in India during the First World War, that shortly after its end the Indian Government ordered 16 Rolls-Royce cars. However, these proved so expensive that subsequent orders were placed with Crossley Motors in Manchester who made a tough but cheap 50hp IAG1 chassis. Substantial numbers of these cars were supplied between 1923 and 1925.
The car shown in this film was presented to The Tank Museum by the Government of Pakistan in 1951.

Richard Hammond’s latest close call
The BBC is reporting on an accident involving an electric supercar:
Former Top Gear host Richard Hammond has been flown to hospital after a crash while filming in Switzerland.
The 47-year-old was on a practice run for a race in an electric car for Amazon Prime show The Grand Tour.
Mr Hammond “climbed out of the car himself before the vehicle burst into flames”, the show said in a statement.
Co-host Jeremy Clarkson tweeted that it was the “most frightening” accident he had ever seen but said Mr Hammond, who fractured a knee, was “mostly OK”.
The show’s statement said Mr Hammond had been involved in a “serious crash” after completing the Hemberg Hill Climb in Switzerland, where a race takes place on Sunday.
He had been driving a “Rimac Concept One, an electric super car built in Croatia, during filming for The Grand Tour Season 2 on Amazon Prime, but very fortunately suffered no serious injury”.
Some video footage was released on the DriveTribe site:
And Hammond himself was able to speak from his hospital bed on Sunday:
