The Random thought thread

I had a random thought when drilling today. Why don't drill manufacturers knurl the top of drill bits so the chuck jaws can get a better grip?

 

I mean to say, who thought trying to get chuck jaws to grip a deadly smooth surface on the top part of a drill bit, was a good idea??

 

I've actually acquired some American-made drill bits that have 3 flats on the top of the drill bit that correspond to the chuck jaws. They don't slip.

I buy bits with the hex shaft that fits the rattler. 

That way they fit both drill and rattler,  and they don't slip when in the drill.

Random Thought:

 

If blokes who paint houses wear white work clothes, why don't butchers wear red?

 

Curiously, doctors and barbers traditionally wore white, too - maybe they should also wear red for the same reason that butchers should.

surgeons/barber surgeon's used to wear the blood stains as proof of experience.

I thought traditionally doctors wore black?

Nah, that's  undertakers. But I think in the early days they worked closely with doctors.

I wonder what the story is with this little critter. Normally the wallabies are fairly flighty when they see or hear the vehicle heading in their vicinity. When driving up the driveway this afternoon, it's mate took off but this one just propped twenty feet off the track. I pulled up beside it, switched the engine off and checked him out for about five minutes. He just sat there staring at me. He's not deaf as his antenna ears were reacting as I talked to him. Maybe his eyesight is failing. He didn't budge until I started the vehicle up again and drove forward.

"For more than 100 years, the white coat has served as a prominent symbol of care, pride, prestige, and authority for physicians. However, until the mid-1920s, physicians wore black coats to dissect cadavers as a sign of respect for the dead. During this time, laboratory scientists wore beige coats. Scientists were well-respected by the public for connecting the certainty of science with modern medicine. In an effort to emulate scientists, physicians began to don beige coats. White later became the preferred color because it symbolizes cleanliness and purity."

I like using drills that I got from wurth. They have stepped tips and 3 flat sides like onetrack mentioned.

Not cheap.but they drill very neat round holes freehand and through thick tough material.

They're wurth it then?

I often cart things that overhang the back of my ute so decided to look up the (Qld.) regulations. I had the idea you could have a load overhang up to 1.2 metres beyond the actual vehicle rear before you need a red flag on the end of the projection. That part is true but not everyone is allowed 1.2M projection of load as it's dependent on axle spacings. The centre line of the rear axle is deemed the overhang point and the maximum overhang allowed should not be more than 60% of the distance between the overhang point and front axle centreline. In other words 60% of the distance between front and rear axle centrelines.

 

In my case, the space between axles is 3100mm. 3100x60%=1860, so I'm allowed 1860mm overhang from the centre of rear axle. Allowing for the length of the tray, that equates to a maximum of 760mm projection of load beyond the rear of the tray.

I had cars with crankhandles and cable brakes. A had a chance to buy an AMILCAR in good nick for about 20 quid. The "I feel really OLD" struck me when I was 45 and had lunch in a pub in Perth and looked around me at the others who were there.

 ALso when I found an XE Falcon hard to park because it didn't have power steering. You're old when the Cops all look like Pimply Kids.   Nev

I was reading where Rip Curl is facing consumer boycotts for featuring a trans bloke on their Rip Curl Women’s Instagram page. Champion surfer Kelly Slater had a good point - why not make a trans division in surfing competition then there would be no confusion. It's a bit odd how multiple genders are being pushed, but they still try to squeeze them into male or female gender for the purposes of competitive sport.

 

Graphic warning: this article contains photos of an old bloke in a bikini. Some things you just can't unsee.
