Spherical bearings are used in boat rudders to accommodate the natural bending of the rudder shaft, preventing the binding issues that occur with parallel bush bearings found in older boats; this design allows the rudder to rotate smoothly in its housing even when the shaft bends under stress, making it essential for reliable steering through tight canal passages.

My wonky rudders : Ghosthip vlog 60Added:
Cool. Set up. These you pop them in.
There's like a slot cut out. Look. So, in theory, we should be able to push it in through that slot.
>> What slot?
>> That one there.
And then spin it round >> into its housing. There we go.
>> These are my rudders. And there's something bizarre going on. One has got a piece missing here and one doesn't.
So, I need to fit these to steer through the canals. So, let's have a look. We're going to fit them and see what's going on. These are the bearings that we have, the spherical bearings.
Uh, one at the bottom, one at the top, and both of these rotate in the housing like this. And that's because the rudder shaft itself can bend in the middle. So, if you have two parallel bushes, which is what we used to see on the old school boats, they often bind.
So in this locker at the back, that's the hole that this fella here should drop into.
Something like that.
Yeah. And I'm not going to put in properly because um it doesn't need to be for this. This is just to get a bit see if it >> When we push the R up from beneath, is it not going to come up?
>> It's going to come up. Yeah. But then I can just rotate and shove it in.
>> Right. That's why someone comes up.
>> Yeah. Cool. So >> I was wondering if there's anything like we could put the corner of the battery or something on it to hold it down when we shove it up.
>> Uh you could, but it doesn't matter if it pops up. Oh, hornets. Still haven't got rid of the hornets.
>> Yeah. Bought the spray. Didn't do anything with it.
>> How much it So both is going to lift that rer up and go in there. Probably weighs what? It weigh 40 kilos. lift that up and then I'll hold it in place and then you can go and drop this one in on top of the shaft. And once you're happy with it, then you'll go down below and just nip the three group screws up.
>> Okay. I think I'd prefer you to do that and I'll hold it.
>> Okay.
>> Cuz we can probably get something to >> Yeah. I mean, >> I collected them myself. If I can lift them.
>> Have you tried remember yourself a weight of them things?
>> They're not that light, you know.
>> I know that.
>> Go on then.
>> Well, just of standing under it like this, won't you >> lift it? Yeah, it will be. You just want to make sure you're happy before you agree.
>> I don't want you losing your toes.
>> Look at Slug.
>> Um, >> hey buddy.
>> We've already had someone uh lose their toes on a rudder before, haven't we?
Mhm.
>> This one had to stitch his own foot up in um Lisbon.
>> My bloody bicycle there.
>> I did suggest we move it. Should we move them?
>> Yeah.
>> Okay.
>> What's the crack?
>> What's the crack? Can you go out towards the side the beam of the boat or starboard?
>> Oh, I need to stop pushing it. Love.
Okay. Can you come back down, Chris?
>> Can you come back down?
>> Too heavy. You keep pushing against it.
I can't hold it anymore.
>> Okay. So, >> can you take it? Can you take it?
>> Yeah.
>> I got it.
Oh, okay. Do I need to >> think if you go up?
>> Yeah.
>> You'll see the patterns.
Good luck tonight.
>> Talk to me. Talk to me. Talk to me. Talk to me. Tell me.
>> Tell me what you want to do.
>> Mine that line where this is it. Sits up against that pllet here.
Yeah. From the inside then.
>> So, we basically shove it up. You under the grub screws, move the thing down, tighten it, and we let go.
>> That's exactly it.
>> Cool.
>> That's the plan.
>> Sorry.
>> You okay?
>> Yeah. Trying to support a bit more.
>> How you getting on, Chris?
>> Okay. Okay, you take the weight there.
Okay, here we go up.
>> That's it.
>> That's it.
>> Yep.
>> Tell Tell him when he can let go.
>> You can let go now.
>> You're all right.
I don't have it anymore.
>> Well done, Criy. So, what we've been doing there is basically lining the two bearings up top and bottom.
So, access is fun. Thankfully, we don't have any furniture, which makes it easier.
It's okay.
I think you run a scribe around here.
>> Right. So, the funny thing is you cannot see it, but I can. There's a gap there.
It's >> Yeah. Like in the middle.
>> It's a half mill half a million.
>> Yeah. It's stuck in the back.
>> Yeah. So, you can see from the back here. You see the light coming through?
>> Ah, you can see it from there. Yeah.
>> Yeah. But it's still not beveled off well. So, >> right.
>> This needs a line marking on here. This is pretty accurate. The other side isn't because the gap I can see is reasonable at the far side at this point. But here it's very tight. So it needs a little bit trim enough here too.
>> And that's obviously incredibly terrible.
But that's okay. We can that I can work with that port.
That thing's light.
>> Oh >> Jesus.
>> I I think you're meant to have like eye and face protection.
>> Sorry guys.
>> Don't breathe that in love.
Are you going to just spray in the bic?
>> Jesus, this is just not right.
>> That wasn't very much.
Is that >> I'm worried about what it is.
>> Oh, on the boat. Yeah, >> we maybe should have read that.
>> What's in a different language? How am I supposed to read that?
>> Yeah, >> is this some kind of costic acid or not?
>> Highly toxic. Yeah.
>> What about on aluminium?
>> Oh, >> we didn't think about that, did we?
>> I didn't. I didn't think about that.
>> Neither did we.
>> But I I sprayed some of that stuff in our aluminium uh uh thing.
>> Test piece. And uh time gone a little bit cuz we had a barbecue while we're waiting for the hornets to die. Then we realized that we actually lovely.
>> It's true, isn't it?
>> Yes, that's what happened. I was going to beat about the bush. Uh and so I think we're the coast is clear.
>> So the coast is clear. We haven't even been up yet to check.
>> Going over this trusty head torch. Don't need the sunglasses.
>> You'll be in charge of this. Thank you.
You ready for this?
>> Born ready.
>> Bearing in.
>> Yep. First time.
>> No flies on him.
>> Nope.
>> No haunted zombie.
>> Hope. Hope not.
>> Yeah, they're dead.
>> Okay. Are you okay there? Cuz I'm just watching.
ow.
>> You all right, babe?
>> Yes.
>> What happened? I got horned.
>> You got horny.
>> No, >> not now.
>> Can't wait to push my shafts in that hole.
>> Y is going to plug it. Just wait.
>> Hang on.
What? That hurt.
>> What? Did it sting you?
>> Well, I put my hand on it. I didn't see it.
Okay, let's go. We're safe now.
>> Let's see.
>> So, I'm just going to film until you ask for help. Is that okay?
>> Can I go all the way up?
>> Okay.
port.
>> Oh, where's Y where's Ymer?
He's just in the bush.
>> Where is Ymer?
>> He's a bit like that.
>> Don't say what I not am now thinking.
My Chris, >> are you making a video?
>> Yeah.
>> Stop it, mate. Make >> Hurry up.
>> Are you presenting?
>> Is that it?
>> Yeah.
>> What is it speaking?
Let it go.
>> Yeah, >> let it go.
You You're sure?
>> Okay.
>> Yeah.
>> Good. Go.
>> It's >> going to spin.
>> Oh, yeah.
>> This is the brake now.
>> It's less than half a millimeter there.
We already signed off.
>> No, I forgot to film it.
>> Let me take that then.
>> What's wrong?
>> I've got a question. Oh, no, no, no.
Chris, what is this? Why is this here?
>> That's for an anode.
So we have like because it's aluminium it corrods. We put like we actually you can put zinc anode on there or aluminium anode to sort of corrode instead of the rudder.
>> Right. That one will get an aluminium button on it.
>> Okay. But it's already aluminium. How does it help?
>> So it's a it's a less noble grade of aluminium which grows faster. So you can use z ink which is probably it's better in salt water but if you're in brackish water so it's like slightly salty it's slightly fresh aluminium works better and aluminium >> works better as well when it's in fresh water but when like boats for example are often in you know when you're at harbor or when you're in an estri or something like that it's often brackish so >> most of the time you don't need to the zinc's generally not as good these days so >> Mhm. But yeah, we'll go into a few videos on all that geeky stuff.
>> Hey, but look at this.
>> Yeah. So, that one's been fed properly, hasn't it?
>> Yeah. Though, here you have less I mean, like it's almost >> It need It needs a bit of action like, doesn't it?
>> Yeah. I mean, like, as soon as you put paint on that, it will bind up.
>> Yeah. Yeah. No, that's that needs adjusting. But this one's much better.
>> Oh, yeah. For sure.
>> But it needs a bit of building up here, doesn't it? Quite a bit.
>> Mhm. Someone's being a little bit trigger happy with a grinder.
>> So, that one looks pretty good.
>> It does.
>> Yeah.
>> Yeah.
And on that note, we'll see you tomorrow.
