How to drill a square hole [in wood]

[Xist]

Someone posted this on Imgur: https://i.imgur.com/zPh341R.mp4

I don't know how to make MP4s or GIFVs work here and they did not link the source.

Have a low-quality GIF!
No no no, that isn't animated and not only did the poser not pose a source, but the square video is 9x16 for no reason!

I couldn't find another version, so I used Vance to enlarge (and enhance) and cropped it:

Of course, the forums shrank it.

So, it shows the squircle rotating inside the square, shows a laser cutting flutes in each side, slightly beveling the tip, and shows it being attached to a shaft and drilled into wood, leaving... a squarer squircle.

This isn't the source, but it is similar:

One or two people shared this:

Is that the same concept? I don't know, he never once mentioned "Squircle!"

Of course, once they made the flutes it wasn't a squircle anymore, it is a 3-sided drill bit--in a square collar, which doesn't wear out?

Of course, even I knew about mortise bits!

I just didn't know their name, but that was the first result when I searched for "How to drill a square hole."

Edit! Two of those don't show up here, so I am trying to find something similar--and hoping they show up here.

This guy tries to make his own bit, which wasn't perfect, and he said said he could improve it further:

He talks kind of funny, so I needed to read the subtitles. This guy used $20,000 worth of equipment to cut a slot in a rod, pin a piece to close in the open side, and then trim it down to have a square hole.

Should I have specified wood?

I don't even understand. He milled a tapered square end, which put corners on a round hole?!

Also, he has a special machine that looks like a scroll saw with a square file instead of a blade.

This guy showed how to file by hand, use a machine he made, a mill to make a squircle, and then he makes a tapered square end like Tony, but tempers it, grinds a concave face, and uses it to chip away at corners of a round hole. Then he uses a bunch of equipment to put corners on a round hole:

this is AvE, but before he was cool?

This one seems like it requires the least expensive equipment, he put a square file in an arbor press and squared a round hole: https://youtu.be/wpD_3UJXzSI?t=27 Are vastly more people putting square holes in metal than in wood?!

"Squircle!"

Made me look.

https://dictionary.cambridge.org › dictionary › english › broaching
BROACHING | English meaning - Cambridge Dictionary
to begin a discussion of something difficult: At some point we've got to discuss money but I don't know how to broach the subject with him.

I don't know how to put this.

Broach - definition of broach by The Free Dictionary
broach (broʊtʃ) n. 1. an elongated, tapered, serrated cutting tool for shaping and enlarging holes

But a squircle doesn't have flat sides.

I finally finished adding videos. For some reason the previews weren't showing up at all until I posted, so I posted one video at a time.

The last video, which is short, has a still of a VW work truck!

I have used a square hole drill for wood and it didn't look anything like that.

That Time Steve Jobs Taught Bill Atkinson About Rounded Rectangles
Andrew Orr -- Jun 2nd, 2020 3:17 PM EDT | Link
Here’s a humorous little story from Andy Hertzfeld, a member of Apple’s original Macintosh team. Bill Atkinson did some clever programming to draw circles and ovals quickly on a Mac. But Steve Jobs had something else in mind.

Bill fired up his demo and it quickly filled the Lisa screen with randomly-sized ovals, faster than you thought was possible. But something was bothering Steve Jobs. “Well, circles and ovals are good, but how about drawing rectangles with rounded corners? Can we do that now, too?”

Once you see them you can't unsee them. A squircle for comparison:



No flat anything.

A mortise bit?

Did Apple patent squircles?

Once again, two different things.

Apple finally gets its patent on a rectangle with rounded corners
There's been a lot of talk over the last couple of years — especially by Samsung during the course of its recent patent infringement trial — that Apple has obtained design patent coverage on...

A Squircle is a continuous curve.

Well?!

I don't care to [continue trying to] explain it, let's ask Wikipedia:

en.wikipedia.org/wiki/Squircle#Similar_shapes

A squircle (blue) compared with a rounded square (red).

Similar shapes
A shape similar to a squircle, called a rounded square, may be generated by separating four quarters of a circle and connecting their loose ends with straight lines, or by separating the four sides of a square and connecting them with quarter-circles. Such a shape is very similar but not identical to the squircle. Although constructing a rounded square may be conceptually and physically simpler, the squircle has the simpler equation and can be generalised much more easily.

It has three sides!

Kin ye nae count?!
