 And welcome to episode two where we were trying to take the top off this keyboard, but it seems like I'm really forcing it and I don't really want to do that anymore. So I am going to take this side off regardless of what I said about possibly about this side actually supporting some parts. I'm just going to take it off anyway because I really want to look underneath here and see what exactly is holding this thing down. So let's take a look. So I'm going to take this screw off first with a better screwdriver. It seems the one most likely to be supporting a part. So I'm just going to remove it and see what happens. Nothing apparently. Okay, so we've got a washer that goes on it. The washer is, looks like it's about half an inch across, and we've got a screw that is, what is it, huh, it's a 632 screw. It's coarse, coarse threads, that's pretty interesting. And it's a little over a quarter of an inch, so that goes in the bag. Let's also remove these guys. So we've got also a quarter of an inch, and the size is 632. I have a feeling these are all going to be the same size. So okay, that was definitely a support for a part. Let's take these bottom ones out. It appears to be something in there, some sort of a gunky substance. Same size on all of these. So there's this little dot next to it. I think that's just a pin that aligns the side. And these, I don't like the look of these. They look kind of like rivets, but I guess we'll find out when we try to take it out. Okay, three more screws. Let's see if I can get a bigger screw in there. Let's get a bigger screw screwed bit, you know. The problem is that these screws are large, but the slot is also thin, which is kind of a weird combination. Okay, last one, I'll get this closer to the edge, unfortunately, I can't see that, but that's okay. It's just unscrewing a screw. Now the question is, will it cooperate with us and come off? So there doesn't appear to be anything holding this on. It just may be that the paint has dried on it, so I'm just going to try to pry it out a little bit. Yeah, it's just like congealed grease and age, I guess, I think. Okay, so I'm gently moving this, and it appears as though this rivet is not actually riveting the actual side, so that's good. I'm going to try to pry in here. There we go. All right, so that's coming off. So that part's loose, it appears as though this back part is moving. Why is the back part moving? It shouldn't really be attached to anything except the bell. So it appears to be maybe, it's something over here, I don't know how they got this on, so let's look at it from the other side. Let me take this handle off, because now it's getting in the way, so, oops, screw back in. I thought I didn't have to measure it really, put the handle in bag three. So yeah, I'm going to pry too hard, there we go, it was just stuck, so let's just pry. Let me get this back on its bottom, and just sort of pull on it. There we go. Oh, there's a screw, there's a spring, so I can just remove that. Yeah, okay, so yeah, these are bearings, or bushings actually, so that held these in place. Kind of a poor design, if you ask me, but the case is actually part of the support mechanism, but I guess that's the early design. Okay, so we're going to set that aside, and then I wanted to look at this underneath to see if I could find out why this thing, okay. So there is actually a screw here, and it looks like, I may have bent that part, I can probably bend it back easily, but it seems to go like there's another part in here that it fits into. Anyway, you put your screwdriver in this hole, okay, you put a screwdriver in the hole, and you unscrew that, and that was probably what was holding this in, I think. So let me go get a screwdriver that fits, and we'll try to unscrew that. Okay, it took some doing, but I found a screwdriver that was long enough, small enough, and thin enough to fit in here. So that's kind of a weird design, okay. So there's the piece. So this is a funny looking screw thing that fits on here. And the end of the screw is, let's see, what is it, is it four something, no? Is it five something? Looks like, looks like 540 to me. So bag three, now is that what was holding the top up? No, there's probably some other stuff in here that I don't know about. So I'm wondering, let's see, anything else that I can see that's holding this thing down? No, let me see anything holding it down. Let's take off the other side plate. So this looks to have two different types of screws. So I've got four over here and two different ones over here. Let's remove the bottom ones first. Here I've got this long screwdriver that will certainly help, okay. This is a little over a quarter of an inch and it is 632. So it's the same kind of screw as was used on the other side. It doesn't look like the heads are any different either. So we'll just remove these screws really quickly, removing, removing, I've got those three screws also, oh, and it just comes right out. Interesting, okay, so there's a gear attached to this and it does, it just comes out just like that. That's kind of weird. That's a weird way of doing stuff. Yeah, these gears are not actually screwed into anything. They just sort of sit on the plate in these bearings. Fascinating, all right, okay, they're very greasy. So, oh, and right over here is the serial number 13308. That's much clearer. Okay, so what I'm going to do here is I'll close off bag three, start bag four. So that I can put these gears in there. So this is bag four, F-13308. So I will put this greasy gear in here. So that's going to be fun taking apart and modeling that. Okay, and then there's also this gear. If we look at it, if we look at it from the side, there is a letter B and a 259 stamp on it. That's interesting. There's a long flat spot here that corresponds to a very small flat spot here, and it just comes right out just like that. So that can go into bag four also. It too is very greasy. Okay, also we have this, which is actually a friction brake. It sort of hooks on to here and basically serves to slow this down. That's really the purpose of that thing. Oops, okay, we've got another part that just comes right off. Just comes right off. So I'll go in bag four as well. Any other parts that want to come right off? No? You're sure? All right. Okay, so that was that. It's all the grease. So I think that's bag four. So that's going to go to the cleaners to clean all that stuff up. All right, so again, I don't really know why the top is not coming off. So it's kind of weird in a very weird sort of way. So let's take a look at what else we can do. All right, this back piece can come right off because it appears to be screwed onto the secondary side plate. So let's just take that off, get it out of the way. So I'm going to start bag five for that. Bag five, F13308. So here's a screw. It's got kind of a chunky head and its size is 632. Wow, I'm hitting all the core screws. That's interesting because the Model K that we took apart had all fine-threaded screws. These are all coarse-threaded screws that we've encountered so far. So that's kind of interesting. So now I'm trying to remove this other screw. It looks like it has a thinner slot. So it always helps to have a whole bunch of different screwdrivers. Same screw. Oh, and the length is just a little over a quarter of an inch. So there's bag five. And now I think, yeah, that there are pins here for alignment. So I should just be able to pry this off from where, somewhere, just pry it right off. Okay. All right. So prying it off is going to be a little difficult because there's no place to really pry. So I'm just going to take one of these pin punches and just give it a little tap to sort of remind it where it needs to go. No? Trusting. It's certainly not being held on by anything else. So yeah, I'm just going to move this back and forth up and down, not really bending anything. There we go. Now it's off. Okay. So all right. So this looks like it's one big piece of, I don't think it's iron because look at that surface over here, see if I can clean it up a little bit. Well, not really, but it's, it doesn't look like it's iron. It has this yellowish tint, which makes me want to say bronze. I wonder if this is bronze, but in any case, it's certainly a cast piece. It's all cast of one piece with the exception of the pins. There's one pin on this end and two little pins on this end. And the rest is basically machined flat where it needs to be, and then drilled and tapped. So, and then there are these places where there would be an axle, I guess, yeah. That's where the carriage axle goes through. And I guess that would have been drilled and maybe reamed. It's a bit shiny in there. So anyway, so that would be kind of fun to model. Any markings on it? No, it doesn't look like it. All right. So that's kind of a fun, fun little piece. So we'll have some fun with solid works on that. So that was bag five. So I'm wondering if I should just take that and put the screws back in. I think on the hole, I'll leave them out. I mean, I have this video record. So all right. What else have we got? Well, there's obviously this whole mechanism that doesn't appear to be attached to anything yet. It looks like it's just loose in there. Well, maybe not so much loose. See how it really does seem kind of loose. But there's this piece that moves up and down. So see there's some other things over here, that turn. Let's see. All right. So let's take a look at the other side. I really wish. All right. So yeah, okay. So we've got this shaft over here, which appears to be held in place. It looks like just this single screw over here. So let's take that off. Let's go ahead and take that right off. See what happens. All right. We've got a screw and a washer. So the washer is about a half an inch across, and the screw appears to be the same as what we just pulled off. So no difference there. Let's see if I can now gently, yeah, this just comes right out, sort of, almost, almost. So there's the end that goes into that kind of semi-circular hole, all right. So there's that mechanism, which we can now set aside. All right. We've still got this to go, and it would be kind of nice to know how to remove it. And it looks to me like, it looks to me like on this side, it's actually taper pinned in. That's a funny little mechanism. Oh, so this is actually kind of like a helix. It's a really funny mechanism. I've never seen anything like that before. All right. There's this end piece here, okay. So what I think I'm going to try to do is, okay, so I think I'm going to try to take this gear off, which is taper pinned into the axle. That could be a scary proposition, but we'll see. So I'm going to alternately heat it and freeze it. And then I'm going to use one of these pins, one of these pin punches. Looks like this one is the right size. This is a 1.16 inch. That's the small end right there. You can tell that right away. And see if we can actually remove that. So I'm going to stop the video for now, and we'll see. And as you can see, I was actually able to take off the top plate. It just required a lot of persuasion, mainly because these key tops are really rusty. So the rusts sort of kind of held onto this. If you look at the back, there really isn't anything there that is attached to the bottom. We've got some sort of a thingling around here, which is basically this thing right here. We've got this rotating thing here from the other knob. These things move back and forth. Got this thing, but anyway, there's nothing that actually holds it on. There are some pins on the front and back that are kind of tight, but anyway, there you go. So I was trying to take this gear off, and I was not very successful. I did several rounds of heating and cooling, and I punched it with what I believe is the correct size of punch, and I just wasn't able to get that taper pin to budge, which is kind of expected, I guess. So unfortunately, I'm going to leave this on for the moment. I've got some other things that I could try to remove. Well, here's a part that comes off immediately, this thing. So I can put that in, I guess we're up to bag five. So I can do that, bag five. This other piece is actually, it looks like that other piece is set screwed on, so that's going to stay. There is this piece, which is, let's see, well, it's taper pinned in on this side. And on this side, I don't know how it's actually held on, but it could be worth trying to remove, could be, but considering that it's pinned in, I don't know. So I'll just leave that for now. Okay, so there is this axle, which may be removable. We see that on this side, there is a screw that is accessible. So let us remove that screw. Okay, can we hold on to the axle while we unscrew it? Because that would be kind of, oh, just one thing that we should note on this side is a thin washer, and again, we will try to remove this. Let's see, I think I can probably hold onto it on one side and try to unscrew it on the other, being very cooperative. Let's try over here, probably not being cooperative at all. There we go, just required the correct screwdriver, I suppose. So we have a washer, and it looks to be the same size washer as the one we put in bag five before. So I'll put it in bag five, and then we've got a rather large screw, which is an 832. It's 832, and the threads look to be about 3 eighths of an inch long. So that can go in bag five. Now let's see if the gear comes out. Is there a taper pin in there? There's a taper pin in there. I really hate these taper pins, but the gear does come off. So there is a little pin on the side of the gear. There's a hole right where it goes. Oops. So the gear will go in there. Anything else comes off? Is that it? Yep. So I think there appears to be a taper pin in there. There's also this spring, which I will attempt to remove. I don't know why it's there, but in any case, I'm going to attempt to remove it. Let me see. I have a little dental pick here. I'm going to just pry it off of the one end, because otherwise I can't see the taper pin. I'm going to hook the end, pull on it, and maybe the other end would be easier. Yeah, the other end is definitely easier. All right, so I can remove that. It's really hanging on. So what do I have here? I have some pliers that will probably help. So that's a big, fat spring. It's very strong. So that'll go in the bag as well. No, I can see that there is a taper pin, but I don't really see which side is the bigger one. So again, this is probably going to have to wait, unfortunately. That is very unfortunate, so highly unfortunate. I don't really want to take this side off, because if I do, then basically these axles will just be hanging off it, and then it'll be a lot more difficult to remove the taper pins. If I'm ever going to be able to remove the taper pins. So I'm going to leave that side on for now. I think we'll probably, let's see, what else should we do? I think the top keyboard mechanism can come out. So we've got, so I believe it's probably just held in place with these rails on front and back, which means that I should be able to remove these two long standoff looking screws. So I can do that, and I can do that. They're the same. So they can go into bag five, and now I hope I can just lift off the keyboard mechanism completely. Alright, so that's going to be also interesting to model. These keys are very different from the K. So, ah, yeah, you can see the reason here. The reason is that these rockers don't have those little extensions that are variously tilted. So that means that the various tilts have to be encoded in the bottom of the keys. So obviously that was, I think, a major innovation in going from this model F slash G to the model K. So that was quite major, I think. It made building these machines a lot easier than making all sorts of different key tops. So we can set that aside. Yeah, I mean, there's not much left to the frame. We've got these rockers, which we really shouldn't remove until we can actually remove this guy. So that's basically how the rockers work. They move these variable teat-toothed wheels over like that. So the amount that you move these gears in is the number of teeth that you get. So this one has five teeth on it, and this one has different sizes, one, two, three, and four. So you can move this different amounts. And depending on how far you press these in, you get, you know, anywhere from zero to nine teeth engaged. Those teeth can just rotate these freely rotating gears, which then rotate the carriage, the digits on the carriage. And this thing is the carry mechanism right here. So it's phased so that it rotates after these teeth are registered. So I think we're going to break now, since we've gotten a lot of major pieces out. Maybe I think the next step is, yeah, we're going to model some of these pieces in solid work. So that'll make a break from actually trying to take parts off this physical thing. We can start working in the software, see how it works. It's not going to be a big introduction to solid works. I'm kind of assuming that you know how to draw a sketch in solid works. It's fairly easy to use, I think. There's a lot of tutorials on the web, so get going with that if you don't already know how to use solid works. In terms of getting solid works, I'll just say that you can get solid works and leave it at that. And I'm sure that there's like solid works trials that you can get as well. So that's always handy. If you have access to a maker space, they sometimes have solid works licenses. You can go in there and just work on their computers with solid works. But in any case, I'm just going to take solid works, make the models, and then export them to various formats, and then put them on Thingiverse, and then you can look at them yourself. So you don't actually have to have solid works. It's just kind of convenient to have. Anyway, that's that for now. That's it for episode two. For episode three, we're going to take a look at solid works. So see ya.
