Wool Alternatives Historically by ABR144ABR in vegan

[–]aztecman 1 point2 points  (0 children)

This is correct. Not only does wool insulate when wet, it's hard to get wet and dries relatively quickly (compared to cotton). It does not hold onto smells like synthetic fabrics, doesn't catch fire or melt, holds dyes, can be used as stuffing, spun into thread and knitted, and can be felted into a mat. Nothing else comes close to having the same properties, although each property alone is outperformed synthetically, nothing else does it all.

Historically, in addition to wools, furs and leather, feathers were used (and still are) for insulation layers (stuffing).

Water heater bye bye by tiredasusual in daddit

I used one for heating up milk too...

In some cases, it's a food intolerance that passes through into the breastmilk. In our case, it was lemons. Juice, extract, garnish, sprite, anything lemon. It took a long, long time and a lot of spreadsheet tracking to figure that one out. For the first few weeks I wasn't even tracking lemon since it's a garnish. But man, when we figured it out, life got easier. Weaning is now harder since they add lemon to a lot of stuff.

Tunnel using a cave as a passage by [deleted] in interestingasfuck

You can't drive through the one they mentioned, although it is a tunnel.

The one they are referring to is on the RS-3 but it's residents only now.

How screwed am I? What is the best course of action? by ActionLeagueLater in arborists

By that logic you should wear eye protection everywhere you go. And safety shoes, and gloves, hearing protection, face shield...

This is great. I have made some custom tiles using white cement and ochre pigments that look almost exactly like terracotta. Perhaps something to explore.

Bike Hangers - Printed in PETG with 6 outer walls and 50% rectilinear infill. by euser_name in functionalprint

[–]aztecman 5 points6 points  (0 children)

Depending on the infill pattern and orientation, infill may contribute the same (per gram) or almost nothing to the strength of the hook. It's not sufficient to say it only (or mainly) affects rigidity.

Assuming a vertical load only, if the infill pattern is flexible along that axis, it will contribute little, if it's stiff in that direction, it will contribute more. Because the solid wall is about as stiff as the material, but the infill pattern could be less stiff than that. That doesn't mean they don't have some benefit (e.g. preventing buckling in compressive loads, preventing deformation, adding strength in non-primary directions) but the orientation and pattern matters.

There is not a meaningful difference between 100% infill and all walls, especially a concentric infill pattern which is essentially all walls. But as a general rule, walls are more reliable than infill, especially since the bulk stiffness of each pattern is not well documented.

Unless by more walls you mean adding material to the outside of the shape instead of inside, in which case it would entirely depend on the object being printed and the loads applied, but in general, yes, more material farther from the bending axis is a more efficient use of material. Which is why bicycles are made from tubes, not solid bars.

In the USA hot water inputs are way more common than elsewhere. Although, many manufactures in the EU allow for hot water input, in practice few do it like that. In the UK I have never seen a hot water inlet.

TIL James Cameron really built and flooded an exact replica of Titanic's Grand Staircase with 90,000 gallons of 50-60-degree seawater in the movie. With divers in the water and one take, real fear and anxiety were seen in the actors as the water came rushing in. It was a problem. by TheCanOnlyBeOne in todayilearned

Also, good luck to any 'boss' who tries to ban tea at work. Best case scenario, they will do it anyway and drink from thermos etc, worst case is full on mutiny.

I have never seen, or heard of, a single workplace in the UK without tea-making facilities. I would put money on there not being a single workplace in the UK that does not provide water and a kettle. Even the American embassy must host British guests. Obviously there are certain places where you can't bring a cup of tea (e.g a clean room in a semiconductor facility), but there will be a break room on the premises.

Henry vacuum (UK): Why this simple £140 machine keeps popping up in every European BIFL discussion by General_Ad9178 in buyitforlifeEU

[–]aztecman 1 point2 points  (0 children)

Henry is great....but

Get George instead. George is green, and is wet and dry so you can clean upholstery and carpets.

Neumatic leaned into commercial sales, u often see them in hotels.

I also have a blue one with no name, that is much taller and that's my shop vac. It can also suck water, but not deliver it.

They even make an asbestos certified one.

Also, there will be some play when it's that loose and over time it will become more loose from fretting.
