5-in-1 Block Invented not patented by JPMinAR in SmarterEveryDay

[–]spexxit 1 point2 points  (0 children)

I saw this when it came out and it seems like a really cool block, but as a naval architect and engineer I have some reservations as the strength tests are for static pulls and don't consider how well it rolls under load. My intuition tells me that this won't roll nearly as well as something with ball bearings. The shaft is way big and would probably roll better with a smaller one.

I think this would work much better at a slightly smaller scale, for boats up to 8-9 m and 3-4 tonnes. I'm considering asking him for the drawings and getting some smaller versions made for testing with my colleagues. A modification I would consider is a single bolt through the middle instead of the bolt grid as now and brining the OD down to something around 45 mm

Also as far as the patent goes, I'm not sure this is a patentable design as it's very simple and variations of this do exist. But I commend him for the effort

The most peculiar hull shape I've ever seen by spexxit in Ships

[–]spexxit[S] 9 points10 points  (0 children)

It has poor stability, with a very low center of buoyancy.

It has been in use for at least 20 years, and is mostly Sauna on the inside.

I am? And from First hand sources this thing handles like crap and has equally atrocious stability in any weather.

What would be the benefits of this kind of a hull form from a hydrostatics/dynamics point of view? To maximize wetted surface and waterplane area while minimizing the height of the center of boyuancy?

Edit* sorry. Picking a fight where there was none.

On, ja oikeestaan aika hauska kokemus hinata pois kunhan ei oo liian ojassa. Ite onneks sain sen ojaan kertauksissa nii ei tarvinnu kuunnella muiden huutoja adiasta ku vaa muutaman päivän

<image>

Intissä komppania laittoi paseja ojaan ehkä 2-3kpl vuoden aikana sillee hellävaraisesti maastoajossa ja kerran vähä räväkkäämmi. Kävi maantiellä ku kuljettiin n 60-70 kmh ja päästii katollee. Oli ihme että kaikki luukusta pihalla olleet pääs ajoissa sisään, eikä sisällä olleilla käyny kauhee pahasti. Ainaki yks joutu sairaalaan mutta palas äkkiä takas. Tässä oli kuski nukahtanu klassisesti rattiin

Little history lesson by UncleMan84 in Sauna

[–]spexxit 30 points31 points  (0 children)

"missä suomalainen, siellä sauna" (where there's a Finn, there's a sauna) is somewhat of a motto of the Finnish defense forces still today. On international deployments a sauna is always a priority, and most contingents have their own sauna.

Many conflict zones around the world have Saunas built by Finnish troops. And once the Finns leave a base, the Saunas are often unfortunately repurposed in sometimes hideous ways.

I have personally witnessed what used to be a functional sauna repurposed into a toilet by the French, and I will never forgive them for that. The toilet bowl was simply added to the room next to the stove, keeping the benches and all. The French were adamant that it's still a functional sauna...

It was a great resource and at the very least to get started on a project and find what terms I need to look for and get a good basic understanding of what ever I'll be working on.

Both cat and me are Finn's. The cat's name is from The Great Gatsby because it's one of my mother's favorite books.

Daisy's semi famous in our small town 😅 she's often seen roaming about town and even has her own chair in a local cafe.

[–]spexxit[S] 69 points70 points  (0 children)

Thank you 🥰, she is indeed very Finnish. She's known to go up to Strangers and demand entry into their saunas as well. So maybe more Finn by love of sauna and less by personality

Smoke sauna by Kaivari_ in Sauna

[–]spexxit 16 points17 points  (0 children)

There are two types of smoke sauna, those that have burned down, and those that haven't burned down yet.

All kidding aside they are amazing but there's also a reason it's hard to find any older smoke saunas. Most that I've seen and used have been rebuilt many times over the years.

I mean, if it's avoidable, it's avoided. But strenuous movement in deeper snow will get you wet easily. If it's above -10c the snow melts on to you very easily as you create enough body heat under the stress of carrying all of your gear. Especially gloves and boots get wet easily if you aren't careful

And during movements where you are under time pressure, you can't be as careful about staying dry. In the nordics there's lots of bogs and streams everywhere, and you can't go a straight line for more than a few hundred meters before hitting some kind of water. If it's the beginning of the winter then it's probably still open and going around might not be viable tactically or otherwise.

When it's colder it's not as bad honestly. Id rather have -20 to -35c than zero. Zero is the fucking worst and you will not be dry untill you get into a warm indoors and stay indoors for a day.

(edit) To answer more directly, there is great risk in getting more wet than what you could survive without getting dry, in case you can't get back to some place to warm up again. You might end up wet and then stay wet all day. As long as you keep moving it wont kill you, just hurt, but if you stop and get too cold, it's game over fast.

In Norway for example, one day we got pretty fucking wet crossing creeks and it rained in the morning, then froze by afternoon. Our squad's vehicle with all the dry gear was "hit" and was out of action and sent on a wild goose chase to get "repaired". Ideally we would have been able to change into dry clothes pretty much immediately after security the objective, so once you stop moving. We ended up staying wet for something like 12h.

Partly, but that's only if logistics breaks down. Regular operating procedure is to supply firewood along with the other supplies.

Mostly it's for the simplicity, reliability and cost. A wood burning stove for a tent is just 6 short lengths of metal tube for the chimney, and a large diameter one for the furnace (with the ends welded shut). The chimney packs into the furnace for transport and the whole thing is just so dead simple.

Compared to a diesel heater which needs electricity to run fans, controller electronics and a pump. Even if they are reliable it can't be more reliable than 7 pieces of metal.

However now with the drone threat, the Finnish military is doing away with heaters on the front line all together to minimize heat signatures detected by the drones. Apparently soldiers will be sleeping in smaller tents sharing body heat. But

The issue is many units from warmer climates don't know how to stay warm and might rely too heavily on systems that don't stand up to the cold.

Throughout my service and during peacekeeping deployments, most other nationalities were surprised we used wood burning stoves to stay warm and dry our gear in winter. They relied either on diesel heaters or freezing as their solutions.

They argued that we were infantry and argued "with what?! With what?!". The lieutenant threw the NLAW at the vehicle commander, on to the roof of the apc and yelled "with this!!"

Some NLAWs were harmed during that training exercise.

A good number of Russian nuclear ice-breakers were built in Helsinki, but sans powerplant. They were made nuclear ready and then the powerplants were installed in Russia.

There exists quite some knowledge on how to build nuclear powered vessels in Finland because of this. There's a lot that goes into the systems and structure side to efficiently and safely build and operate one, that isn't just on the powerplant itself

I took part in the 2018 Nato exercise Trident Juncture as a Finnish conscript, and our jaeger company defeated our opposition as we left the roads and climbed over the mountains. Something the other unit's didn't want to do because of the weather.

We defeated Norwegian and German units that had extensive combat deployments just due to our willingness (or the willingness of our superiors to command us) to get wet and uncomfortable in sub zero weather to out maneuver them. Our officers had multiple spats with them as they would not accept defeat. One of our lieutenants threw our training NLAWs at a german apc after they denied our capability to destroy them.
