or a crap cocktail.

Well I mean, Nevada is Vegas, Reno and nuclear test craters.

Or you could buy a Skyhawk, three Toyota Camrys and fuel for a year.

Magnificoooooooooooo

From an old edition of the Pilot’s Handbook of Aeronautical Knowledge:

An airplane’s tire will hydroplane at a speed in knots equal to 9 times the square root of the tire pressure in PSI. So if your tires are inflated to 36 PSI, sq.rt 36 = 6 * 9 = 54 knots. If there is standing water on the runway, you will have no braking authority or steering control from the wheels, you will have to maintain control of the aircraft with the flight controls, and you cannot rely on short field stopping figures from the POH if it requires applying brakes above 54 knots.

I got that out of the 2003 edition; I don’t know if it’s in the current issue.

There was kind of a retro thing at the time; bell bottoms came back for girls, carpenter jeans were in for boys…his shoes and her socks would have been out of style in '06 but other than that yeah.

My teacher said the same thing. To this day, there is a Casio scientific calculator in my pickup truck, one in my backpack and one in my tool bag, I also never leave the house without my smart phone and I usually carry some kind of Linux laptop or tablet with me on any significant mission.

Ask Randall Monroe.

In my experience, “writing a proof in math” was an exercise in rote memorization. They didn’t try to teach us how any of it worked, just “Write this down. You will have to write it down just like this on the test.” Might as well have been a recipe for custard.

Just thought of another way to do it: A stationary pinion at the center driving a rack that moves the router along the arm. Which makes me wonder if that’s a marketable product, if I could patent that and sell it to Milescraft. They seem to love bullshit gimmicky router accessories.

In one of his videos on the Antikythera mechanism, Clickspring approximated a spiral as a series of offset circular arcs using a trammel and scorper. He makes soul achingly beautiful machining videos, go watch them.

I think I just invented a relatively simple router jig to lay out and cut a spiral/scroll. Imagine a circle cutting jig, but the router is held in a track. The pivot is anchored so it doesn’t turn, and the arm/track circles around it. The router is pulled in/pushed out by an acme screw that runs through the pivot, and the nut it rides in is turned by a bevel gear from the pivot. So as you push the router around its orbit, that action turns the lead screw. That should get you a constant rate spiral, and you could adjust the pitch by adjusting the ratio of the bevel gears.

Or do the “wind a string around a drum” technique but I don’t like the idea of doing that with a ROUTER.

Okay, now you’ve nerd sniped me. The only way I know how to do something like that would be with a CNC. Or very laboriously chase it out with chisels.

To address the burning issue, generally speaking you want to increase feed rate, decrease spindle speed, and decrease depth of cut.

What I would do is set up stop blocks on your jig so that you can confidently put it against the stop, plunge in, plow a pass, hit the stop, plunge out, rotate the turret, repeat to final depth (2-3 passes for this operation). That way you don’t have to do the “careful…slowly…don’t overshoot…” thing.

I would also recommend an up-cut spiral flute bit with dust extraction.

Americans have one big category called the “trash can.” This encompasses the little one in the bathroom, the waist high one in the kitchen, and the chest high one with wheels outside that you roll to the curb.

The British call the little ones inside “dust bins” and the big one outside a “wheelie bin” because it’s got a built-in hand truck. I do like the American term “dumpster” over the British “skip.”

At a shop I used to work at, we had these old computer chairs with hard plastic seats. The plastic would flex and crack just forward of where the metal seat pan was, so when you sat down you’d inevitably apply a load to the front edge and open this crack up.

We joked these were Trump brand chairs given their tendency to grab ya by the pussy.

Hobby: Video gaming.

Try to determine what kind of video game a movie character is playing by what they’re doing to the controller.

Yeah, at maximum Feloneigh spelling.

The only other package even remotely compatible with Linux is OnShape and their licensing terms are a non-starter. Frankly so are AutoDesk’s.

Why the fuck should an end user of mechanical engineering software know how to use Git? Does Blender leave entire features completely undocumented expecting their audience of 3D animators to write their APIs for them given nothing but the app’s source code? Does GIMP? Does KDENLIVE? Does Arch Linux? Hell no, Arch has a massive and detailed wiki. Imagine if there just was no documentation for how to script in Bash and the Arch devs were like “Oh yeah think you could write that for us? You know, while you’re trying to get something fairly basic done?”

Think they’ll name their next daughter Cheaughtgeughn?
