That seems to be a 'frog in the pot' rationalization, and as for whether Google wants to listen to what Alexa hears, there isn't some guy sitting behind a computer listening to individual Alexa terminals, where does it end?

That's technology for you, we can still read 4-5,000 year old cuneiform tablets and Egyptian hieroglyphs but can't read a 20 year old floppy disc.

Instead of getting rid of the height gauge, why not get a decently thick piece of glass as a surface and start using the height gauge, they are much better for doing layout lines than your calipers, and more appropriate as well.

I was at the Georgian Bay steam Show this past summer and saw this engine, does anyone know what it is? I was talking to the person showing the engine and asked about an IC engine and missed asking about this one.

Not sure how it compares to the ones you listed but another is free on Archive.org, printed in 1902 so well out of copyright. A handbook on the steam engine

Some people were concerned about the government giving you a 'chip' when you got a COVID shot, the insanity of that idea is that 99% of the population willingly carries one with them every day in their cell phone, the West's 'social credit system' is already well developed and ubiquitous, 'they'...

Interesting timing because I just saw a video of a praying mantis taking a hummingbird.

DRY kitty litter/Floor Dry works for larger pieces pretty well, too, or put it in with another, larger piece beside the one you want annealed.

I just checked with Canada post, regular envelope, maximum thickness less than 5mm and 30 grams, $2.71 CAD postage, no tracking or insurance and over those dimensions parcels start at ~$20, but USPS might have different rules. $AUS/CAD is usually about the same. I'm semi-retired but still buy...

That only works so long as the top and the bottom of the surface plate are parallel but for sure, not all surface plates are made that way, the bottom is not a precision surface, I'd at a minimum, check parallelism be fore tramming like that. A large brake rotor would work as well though, if you...

That seal is all of 1/8 inch thick, someone buy it, stick it in an envelope and send it as a gift.

Richard, about the time you got your Amiga, I got an Atari 520ST, they had issues with Apple because they more or less copied the MAC graphical UI, with Lotus 123 and, I can't recall the name of the CAD program, but there was no typing point by point to get a line like ACAD, it was graphical UI...

Keyshot is included with Alibre Expert, current price, $1399

As much as I like Alibre, there's a reason it's a $1500 program, not a $5000 program, it doesn't have a capability to produce surfaces and a few other things but yes, as far as I can see, it will do almost anything most modellers, miniature engine builders or hobbyists will need. SW is a...

Not to nit pick but tolerances don't represent the errors of the machine, they represent the allowable deviation from the nominal dimension

Yes, you are correct, I have expert so was only going by what I saw online.

No, give it a try, it will produce counterbores, countersinks, recessed countersinks, tapers, flat bottom holes, drill point holes, blind or through and a number of different series of threads to different depths, far more than a circle extruded cut. If you expect a hole tool to produce a shape...

Here's the hole function and it is in Atom https://www.alibre.com/AlibreDownloads/Alibre_Atom3D_Exercise_Manual.pdf

It may not be in the Atom though I suspect it is as it's so useful. When you are adding a new feature to an existing part or assembly and you open a sketch, in the top left of the ribbon there is an icon for the function.

True, as far as I know, no CAD allows you to build with tolerances, maybe higher end software but I've not used them so I can't comment on them but frankly, neither does drawing by hand, in all cases, someone has to put tolerances on the 2D drawings that are sent to the shop for manufacture. You...
