 Okay, welcome back to the disassembly of the Monroe model K calculator I have moved the camera down a bit so that we can see more from the side I've also put this little black background over there to Hide some of the clutter. So hopefully you'll be able to see things maybe a little better. I hope so Before I took off the clapper mechanism for the bell ding bell In order to get at this lever right over here So that I can remove it from here. Now this lever is held on to this other lever with Basically a retaining clip So if I can remove that retaining clip I can take this lever off of this other lever and then lift off this entire axle I'm going to take this bell off first Just to clear it out of the way And then I can put it in bag four along with the clapper So I'll just remove the bell So here's the screw It's a 640 screw That is Point two forty four So that will go in the bag As well the bell which just comes off of that bell, okay Now the bell is off. We can sort of see things a little better here Here's a lever Here's the bell on off lever So, okay, so this lever here What we need to do is take off this retaining clip now. This isn't like a modern like C-clip or E-clip It's just a piece of wire So it's probably a piece of spring wire So I can probably pry it off and that's where these two tools come in So we have the dental pick and the one millimeter Screwdriver so what I'm going to attempt to do Is find the break in the wire and Then try to Open up the wire. So there's the break. I think So what I'm going to do is I'm going to put the screwdriver Into the break and try to pry that apart. That's not working very well Sometimes it just takes a little while to Remove it I can Push on it from one side and maybe Pry it with the screwdriver from the other side. No this is This is one of those kind of frustrating moments Where you have to try not to do a lot of damage. No, this isn't pretty tightly Hmm, let's see what else I can do with it So I can get all right, so it was just really a question of Getting that break in the wire to open up a little bit So that I can now Sort of open it up a little more Just open the wire up and now Let's see if I can sort of lever the thing open But the pick on one side and the flat of the screw driver on the other side I just sort of try to Lever the opening which isn't working very well But it will soon Soon this is proving to be a bit of a pain so If I can still Lever this open I think my hand was in the way for most of that which is kind of a pain sorry, but I'll see if I can do this from the other side This must make for incredibly boring video, but I think I've almost got it Yeah, now it's open. Okay, so Now what I can do is just use the pick And just pull at it very carefully so that it doesn't jump away It's my hand in the way not really And there was a washer that came off as well. So there we go. I'm gonna start another bag For this thing so we're on bag five now Bag five seven seven three three nine, okay so clip and Washer now with washers again, I don't know how many washers I'm going to pull off this thing So I'm going to measure the washer in its thickness So it is point zero three four Inches thick and it's outer diameter Which is point three one five and it's inner diameter Which is point one five three and And just for completeness, I'll take the retaining wire clip and Measure its wire diameter, which is point zero three seven okay, so What I might do is replace that with a modern C-clip not quite Not quite It's a little bit anachronistic, but I think that I don't know I think it's a better thing to do. Okay, so now this lever could come off I can just bend it and it removes And now it's off and now I should be able to pry This axle off so I need to find a good pry point So that I don't damage anything See, can I well, hmm if I can lift this no Can I pry let's see How about this way this way about this way no this way How about This way here we go just lifts out. All right, so Let's have a look at what we've got so it's loose now But there are these Kind of clip sort of things here and there's another one on this other side So There's this clip here And that just holds this in place I should just be able to pull it out So here's one side and the other side doesn't seem to want to come out really well I'm wondering why that is. Is it attached to something? It doesn't look like it. I may just need to Pry it out slightly more. What's it catching on? Nothing that I can see. Well, okay, so this this part is loose I'm just going to lever this out. There we go That's all that was happening All right So there we go, it just levers out and you just pull it free of the clips and there it is the Leibniz wheels so spring-loaded for each one and It kind of looks like each wheel is made up of Several plates, which is kind of interesting The one that I took apart Actually has fingers that reach out this way So there's a short finger here a longer finger here a longer one over here I Guess that's this is another way of putting one of these together. So the Leibniz wheel the Leibniz axle So this is an assembly. I'm going to set it aside Okay, so let's take a look at What's left? So I removed that So that I could remove this top Assembly which is basically two axles There is this These are called the intermediate gears because they basically Transform motion from The Leibniz wheels to the carriage gears so intermediate gears and then there is this part which is just an axle that holds on to a bunch of Leavers one of the levers is this clicky thing and there's one for each wheel this is actually The lever that indicates a carry to the next Digit so what happens is the carriage wheel spins and then when it goes from nine to zero or from zero to nine There's a little tab that pushes this lever down and on the other side of the lever If we look at the the carry thing this thing right over here it spins around like this and if I Click one of these levers You can see that there's a thing on the opposite side that pushes out and as the carry turns It actually pushes one of these Sprink-loaded they call them dogs. I don't know why it actually pushes that Which will turn the next wheel? And I don't know if you can actually see that turning but the next wheel turns And then as it continues to turn there's a tab Which resets the lever and that's the carry mechanism which is pretty clever All right, so so the thing is that I was going to take this out so And the reason that I couldn't take it out is that I could get to every screw except for this except for This screw right in here because this roller is in the way So I need to remove that somehow and my thinking was this roller is Connected to this entire assembly right over here, so if I can just remove this entire assembly I can Well not remove it, but if I can loosen this I can tilt this Backwards like this so that I can get at the screw The there is a spring holding that which apparently I just loosened so that's all right And now I just need to undo this This screw which I previously undid There is a nut on the other side, so Let me remove the nut first So there's the nut and then I Can remove the screw now again whenever you're removing a screw with lots of parts on it You need to be able to put it back together again in the right order so Let us note that there's the screw and then there is this clip Which held on to the Leibniz axle and then there's this other lever with the spring on it And then there's the frame and then there's the nut so There's the screw there's the clip and there was the axle Okay, and as you can see I can now move the roller backwards so that I can reach the screw Now if that's the way they actually put it together, I'm not sure But it sure looks like it because I can't take this out So obviously They could have done it like that, so let's measure the screw So this screw is a number 836. It's got this huge shoulder on it the total length of the screw it's actually got multiple shoulders is 1.226 and To the first shoulder is 0.464 to the second shoulder is 1.117 so Anyway, just some numbers so that I can differentiate this screw from all the others, so I'm going to take the clip Put it in going to take the nut put it in The spring seems pretty steady so Now what I'm going to do is Unscrew all of these screws starting with the most difficult one the one that I was having difficulty with so let's rotate this Now it is unfortunately hard to see this screw Actually levering it this way doesn't help. It's lifting it and levering it that way that actually helps Again, if I didn't have such a fat screwdriver I could get in here more easily, but there it goes I'm not really convinced that this angle was the best angle For the camera. I'm going to lift it up a little bit So we're removing this screw Right here. Come on screw. There we go It's as good as anything. So there's the screw It is a number 836 and its length is 332 So now I'm going to remove the other screw on the half bushing This two is a number 836 and it's 0.315 Now the question is can I remove? Yeah, there we go Okay, so there's the entire assembly So This is how it went into the machine and you can see that you can tilt this and Remove the piece so that's how it goes back together You simply put it in like that in the slot Okay, and the orientation is like this There is a screw head over here But as before I'm just going to leave this as a single assembly Eventually we're going to want to replace this part because this is the broken broken off thing so So it looks like I probably could unscrew this and remove the lever and at least model this part and then make something up maybe you know use this other part pull a Jurassic Park and Get a new part from shape ways. So I'm going to put this all in bag five Okay, there it is And now I am going to remove The next set of screws 836.334 and the screw that comes after it 836 335 Okay, now if I take this half bushing off you can see here that there is a Spring that runs the entire length Up to here and this spring holds these sort of I'm not sure what you would call them. They're not washers. They're kind of sort of bearing surfaces But anyway, they form a detente mechanism So the gear turns and snaps into its place Move the carry mechanism a little bit. So the gear moves and Snaps into place on all of these except for these last two So that's the purpose of that long spring so Obviously when putting it together they probably hook the spring onto something and then ran it ran the wire through and then pull it all back So that's what we're going to have to do eventually But whoops, yeah, so obviously the spring just sort of bounced back and we have This little piece that holds the spring so that goes in bag five These little detentes Now can come off. So they look kind of like little pulleys. So let's call them pulleys So they go in bag five So I can pull them out now. I can try to pull them out Okay, there goes another one. Let's see. Okay. This one seems to be Move that one. So the spring is now It looks almost fully in its compressed State it's holding on to the other pulleys. So we'll just leave it like that and we can take them off later Okay, so now these this the sides of the axles here are loose So now I can just go on to the other side where we have one two three screws to remove So let's do that I'll start with the bottom one Which has a spring on it and also this roller this other roller mechanism thing So I could I could also remove this Why not so it's got again Just like the other side It's basically a lever with a spring so I can just remove the spring Okay there's a screw here and behind it is This clip which I think is the opposite order is the other one where it was the screw head first then the clip then the Lever then the frame and and so on so let's go ahead and remove this and there is a nut on the other side as well So I think I'll probably have to hold on to it with my pliers and I will have to Somehow Unscrew this. Yeah, this is getting a little difficult Let's see. What can I do? Oh, well, I can probably just loosen the nut on the other side. Yeah It'll work and now It should be easy It'll require a lot less force to turn. I'm just loosening the nut now Loosening loosening almost there Okay, there is the nut. I'll set it aside for now and I will Hmm this is this screwed in the frame. I don't think so just push it out. There we go. Okay, there is the screw It is a Number 8 36 from top to bottom it's point seven four four To the shoulder it's point four six nine and what I'm going to do is I'm just going to screw its nut back on Just so that they can pair up And now I can also remove the clip Clip comes off now. I'm going to take this clip I'm going to put it here and I'm going to compare it with the other clip because it's a similar looking part But I took it off of the right side So this is the right side and this is the left side and yes indeed they're identical So I don't have to worry about mixing them up if I did I would put it in a separate bag Okay, so now Now that this entire lever assembly thing is loose I can go back here and Unscrew unscrew This side now there's still there's still a spring over here, so I'm It's it's looped into a hole here, and it's also looped into while it's behind the gear Now there we go, so I just turned it And it's also looped into the hole over here so you can see it over there, and this is clearly a chem So the question is do I remove the spring from here or do I remove it from here? I think that what I'm going to do is remove it from here so I'm going to have to take my long nose pliers and Rotate the hook Until it comes out just like that And now this is off There we go So when I put it back down, I I sort of have to be careful not to damage this Over here, so it might actually be a good idea to remove it all together So I'm wondering if I should remove this part. Yeah because what might happen is I Might damage it and bend it and that's no good. So let's remove that screw Looks like it's a big enough screw that I can use my very large Okay, I can't actually use my large screwdriver because its Bit is too thick So I'm going to look in my other set of bits and see This seems like it would fit Bit This bit fits. Oh, and you know what actually if I look over here It actually looks like there's a nut. Oh, yeah, let me open Lift this up a little bit. Okay, so it looks like there's actually a nut here, which is whoops Sorry a nut here, which is holding this screw in so maybe if I use a set of pliers And I unscrew this There we go See that's easier There's this kind of long nut over here Then I can simply remove this And there's nothing else there no washers or anything Okay, so it's just about time to wrap up So I have just enough time to measure this screw which is What is it? It's actually a number 1032 that's unusual and Let's take a look at the structure here So we have a bushing a lever and a washer now what I'm going to do is I'm going to keep this all as one assembly I'm going to put the nut back on Okay, that way all the parts are together. I'm going to stick it in bag five Okay, so now I can drop the machine back down and oh great There's yet another part that I have to worry about So Well, I can do that next time So until then Till next time. I'm Rob. See you
