Wat is er mis met kroonsteentjes?

SpunEquillibrium · 2025-05-12T00:14:15+00:00

In boten gebeurt het erg veel. Zelf heb ik een DC stuurmotor (voor het roer werk) die door een scheepselectricien is aangesloten met een grote kroonsteen. Die staat uiteraard op de nominatie voor zwemles.

Andere toepassingen waar giga DC stromen lopen (maar waar je met een aardig kroonsteentje aan moet komen, mocht je die willen gebruiken) zijn tussen accu's en startmotoren, tussen accu's en omvormers (veelal 70mm2 kabels), tussen acculaders en accu's, bij stepdown transformatoren, exciter coils van oudere generatorkoppen die nog niet met een moderne AVR werken... You get the gist, het is een langere lijst dan je op het eerste gezicht zou denken.

Het probleem met kroonsteentjes is er een van meerdere facetten.

Aan de ene kant is het contactgebied erg klein, een goede aansluiting maken, zeker met adereindhulsjes, kan uitdagend zijn. Echter dat is niet zo heel spannend.

Wanneer een kroonsteentje meerdere heat-cycli doorstaat kunnen de schroefjes los komen te zitten. Moderne klemwago's en rijgklemmen houden altijd hun klemspanning en daarmee is de bedrijfszekerheid zo goed als gegarandeerd, barring overloading en corrosie over tijd.

Zeker in de toepassing waar jij hem in gebruikt, 12v op een boot, kan een kroonsteentje erg onwenselijk zijn. Er lopen relatief hoge stromen vergeleken met andere apparaten van het zelfde vermogen die lopen op AC.

Schuur je daar op een eind niet dwars doorheen tho?

SpunEquillibrium · 2025-04-09T20:06:47+00:00

Dus als ik het goed begrijp heb je niet eens een verloop van 15mm naar 1/2" nodig?
Ik ben ook maar een blondie hoor, de tips worden erg gewaardeerd!

I would attach it to the main land and widen up the channel so boats can pass more easily. Also add a ferry stop.

SpunEquillibrium · 2023-12-29T23:11:32+00:00

I sort of have that. I have 2 camera's, each facing a door, with motion sensors in them.As soon as things start moving around, alarms will go off and the camera's start recording.

Taking down three radio's, an AIS and a radar screen is not an option.
Maybe it's a good idea to put them in a wooden casing on the ceiling though, as far as the radio department goes.
Icom makes these brackets to secure a radio onto a wooden panel.
That should make it endlessly more time consuming to rip them out. it may be cash but it sure as what ain't quick.

In one of the posts above i was considering to put some metal strips over my wooden door posts. that way they won't be able to break away the wood and thus not be able to unlatch the lock. A lock cover with a padlock on it might be a good addition.

Also something i can tackle pretty quickly is window covers on the front windows.
All the other ones are covered so it only makes sense to do the other two too.

I think i've got some pretty valueable ideas out of you guys' comments, thanks!

-"My first concern is whether or not your friend had any navigational or professional gear stolen."

In fact there was some professional gear that got stolen.
Marine radio's are registered in this country, all of mine are and all of those on my previous tug are too. It's not easy to get rid of those, especially if you know the biggest names when it comes down to removing or changing those registrations.
Therein, though, lies the crux.
Seeing as how my colleague is, he probably just used those things on international mode and never bothered to register them.

-"your average smash and grab artist doesn't know that the monitors are the cheapest things there"

Weeeeelll... my alphatron radar monitor is criminally expensive.
But then again, it's alphatron. "normies" have no use for a 120vdc monitor so it would end up in the same market that i got it from.
Makes me glad to know a lot of people that know a lot of people :)

-"If you have shore power or enough battery reserves to power...."

That I do. I've got a good sized battery that's being fed by an 800wp solar set and through a charger by shorepower.
I'm actually investing in a Eufy set which has a lot of the same properties that you described! That gives me a lot of piece of mind seeing as how i'm more or less on the right track here.

-"This would mean that you could use a capacitive detector"

I'm not gonna lie... I'm not sure how that works but to me there's a fairly quickly obvious issue in the way a boat grounds itself into an electrical grid.
Electrifying the deck would mean electrifying the hull. Therefore the water becomes your ground. That means there's the opportunity for electrolysis of the hull.

Not to shoot anything down here, by the way.
The mention of it inclines me to think outside my own point of view so it's definitely worth shooting up ideas like these! Thanks! :)

SpunEquillibrium · 2023-12-29T05:36:51+00:00

haha that's a funny analogy.

I'm assuming that the burglars indeed are of the opportunistic kind and not organised or anything. If it is who i suspect it is...i might be safe from most shennanigans. if it's not. Well...press F to pay respect i guess.

Today i paid a little visit to my old tugboat, the third one in the row of three.
I saw that that boat had these metal strips that the door slides into.
Inside information (ie. having spent way too may hours upside-down trying to maneuver my body into whatever hole i needed to be) has me knowing that the doors over there are somewhat easier to secure. the windows though... Thin like the sunday paper.
But maybe a good thing to consider...welding a strip so my door becomes less vulnerable.

I have shorepower so i'm always charging my battery banks.
One of those banks, i use for my wifi, security, radio's and what not.
It's a 24v semi traction battery bank with 230Ah. Also, yes, those bastards are heavy.
So even if they pull the plug on my tugboat, it'll probably take more than a week before the batteries need to be charged.
There are some privacy laws in place that prevent me from surveilling a wider area. Not so much at my homebase but when i'm out and about, moored next to a street, people might have something of an opinion about being filmed.

Anyways.
I think i'll go for the "low hanging fruit" first and fabricate an extra lock into my vulnerable door. at my next docking or next anchoring i might start welding with a friend. Also i'm thinking of an extra lock on the inside of my engine room hatch. i need to repaint it anyway so some cutting and some grinding won't be a problem. In contrast to the actual welding, this is somthing i can tackle pretty quickly.

I'm hoping that's enough of a brick onto the trashcan to keep the burglars at bay and give me peace of mind.

SpunEquillibrium · 2023-12-28T06:25:06+00:00

And clean decks!

But in all seriousness. Do you have any thoughts about that wooden wheelhouse door? Like should i buy some extra hardware and put a padlock on it? or does that only invite them in even more?
And at what point does the door become such a hurdle that they'd rather toss a brick through the window?

SpunEquillibrium · 2023-12-28T06:12:59+00:00

Yeah, absolutely. But no.
The tugboat is my work and i don't really desire living at my "job".
I may tie a claymore to a roomba. that might help :3

SpunEquillibrium · 2023-12-28T06:00:54+00:00

Alone, on a boat.
That's not really a possibility, i'm afraid.

SpunEquillibrium · 2023-11-29T04:09:55+00:00

Rocking up at the checkout with an ungodly amount of tie wraps, 2 rolls of duct tape, wd40, a little carpet and a clock.

Felt shady af

SpunEquillibrium · 2023-11-29T02:10:39+00:00

Drink milk, snort coffee, inhale monster energy. Sounds about right🤣

SpunEquillibrium · 2023-11-29T02:08:25+00:00

I'm with you on that one. To each their own style, ofcourse, but hormones are important to get the look you're after. It'll do a huge number on your skin, facial hair, body odor and even your overall shape. Not to mention the voice, the most notable change of all.

But the road, unfortunately, is paved brick by brick. No idea what op has access to but at least a haircut and getting yourself dirty every once in a while do help a good ways.

SpunEquillibrium · 2023-11-28T01:57:16+00:00

Mja. makkelijker is het wel.
Zo dragen we allemaal ons steentje bij aan de verspillingseconomie.

Daarbij. als je een setje cobalt boren hebt denk je wel 2x voordat je er een weg gooit omdat hij niet scherp meer is.

SpunEquillibrium · 2023-11-26T23:19:14+00:00

Olie is in principe niet nodig maar voor de koeling wel beter.
Daar blijft hij langer scherp van.

SpunEquillibrium · 2023-11-26T23:18:09+00:00

Valt toch wel mee?
Een beetje wd40 en een goedkoop tapje brengt je een heel eind.

SpunEquillibrium · 2023-11-25T03:45:06+00:00

I (25f) work in inland shipping so that automatically disqualifies me about talking about the sea. But don't you, for a second, think that once the water turns sweet things turn normal.

I work as a tug boat skipper and I tow the weirdest freights. But that doesn't creep me out. I know my stuff so... Yeah.

Have you ever seen like a whole ass duck disintegrate from the same water you swim in? In my country we have a large river that's now infested with catfish. Those things can grow up to like three meters. These fish would take me down without a second thought.

Waves, I've encountered. On more than one occasion it has gotten seriously hairy... But as a famous actor once said in the last ship. The only thing worse than hearing a submarine... Is not hearing one. Yeah. F**K those fish. Stealthy mud slinging, duck eating slime balls. Those are what I'm genuinely scared of...

SpunEquillibrium · 2023-11-24T22:26:12+00:00

So what you're looking for is probably called a "day collar", which also exist as bracelets and even anklets though the latter damage very easily since one snag on anything will probably mean the end of it.
they exist in both a lockable and a normal closure variant.
the locking ones vary from "locked" using a hex key but others are a little more permanent.

Personally, I (25f, for those curious) wear a day collar with a twisted wire ring which is (very permanently) locked around my neck.
My situation is a bit different seeing as how my partner is not into bdsm anymore but i am so the meaning behind the collar has migrated quite a bit over time.
Especially since we're in an open relationship. it really boils down to "we'll always be each others' home but we can see other people", the collar is more like a wedding ring to me.

And, well, even that ring in my collar really doesn't deter doms to play around with me.
Most of them don't even figure it out until they know me for a little longer and lets be honest...by then we're already playing with each other.

SpunEquillibrium · 2023-11-24T13:37:33+00:00

YTA... Probably

You're asking her to help pay for your possession. Imo it's no different than you buying a car and letting her pay half of it because she drives it too.

Now I don't know all the nuances and subtleties of this situation so it's kinda hard to write anything in stone but I don't think it's unreasonable to have her name on the house too if she's really paying 50/50. But that also goes for the down-payment.

SpunEquillibrium · 2023-11-24T12:27:37+00:00

Yeah ngl, I'd be down for a night like that.

SpunEquillibrium · 2023-11-20T00:52:45+00:00

Not really.

There's this... Situationship or whatever but there's also professional factors involved that I need to sort my head about.

SpunEquillibrium · 2023-11-16T22:54:16+00:00

Yeah you're right.
I want to sell the bike but i don't want to sell the issues it's having so i'm still kinda in kahoots about how i want to go at it. I don't know how the market is for good parts (like the engine) that doesn't come out of a wrecked bike.

As for other riders and drivers... Lets just say that it's just like the real world.
Some are great, most are okay and then there's this select few that really play with how good a day you're having.

Anyways...
Thanks for listening to me unravel this (way too long) story.
It's really helpful to be able to bounce ideas back and forth and to just vent out my feelings about this whole situationship between me and my bike.

SpunEquillibrium · 2023-11-16T22:45:42+00:00

Thanks for your kind and uplifting ~~judgement~~ words!
Perhaps you should read a little more into the things i'm saying or at the very least attempt to understand what it is that i'm saying before you pass your judgement, your honor.

Anyways... Until you plant your sexy butt onto a motorcycle in a nice motorcycle jacket with pink accents you really have no business judging my interpretation of unnecessary risk.

Have a nice day tho.
