A universal milling machine is defined by its swiveling table, which can rotate 45 degrees in both directions, enabling operations like helical spirals, thread milling, and scroll cutting that would not be possible on a standard milling machine. This swivel feature distinguishes universal mills from conventional milling machines and allows for more complex machining operations by changing the angle of the cutting tool relative to the workpiece.

Workshop and Project Update No 003Hinzugefügt:
Hello and welcome back to the shop.
I've just been looking on the computer in the house there looking at uh my website for the YouTube and we've got 1,7 subscribers. Wow, that's quite a lot. So, thank you very much to each and every one of you who subscribe to the channel. Very much appreciate that. and everyone who watches and likes. That's really great. That is the reason why I started doing this was really an extension of what I'd been doing in me career as an engineer. And towards the end of my days in in industry, I was involved responsible for and involved in the setting up of our apprentice training system or scheme. and we won quite a few awards uh with our system and really this is an extension of that. What I'm trying to do is to put out information and knowledge that I've gained over 45 years in industry out there to people because there's a definite lack of certainly in the young with the young people. I know a lot of evol industry and you know all what it's all about and that's great but how do we give that to the youngsters now this is a great way of doing it because there's choice every person who's subscribed and every person who likes every person who views a video has a choice and it's their choice whether to do so or not so I'm quite a big believer in freedom of choice you can either switch it on you can switch it off. You can watch it or you don't watch it. It's up to you. Obviously, quite a few people feel that they'd like to watch it and that's great because it means that the information that we're putting out there has meaning to people.
It's of relevance and use. The only disappointment really is that I can't go back to where I was 40 years ago and show you the the industries that I I've been working in. You know, I worked I say my apprenticeship at Mitchellin and I spent three years on the factory before I left and I moved to another company that that made a machine called a filter press and other machines that were used in the ceramic industry and that was before we left.
There was three of us left there and we went set our own business up and we ran that very successfully.
But the really interesting satisfying part for me was the apprentice training thing. I really like giving people information, especially the youngsters. They got no they've got no concept nowadays as to what industry is.
They've got no concept as to what engineering is because it's not out there anymore. It's not out there. And for us, when I was young, when I was a youngster, I lived on a council estate.
We grew up on a council estate. You know, my father was a soldier and my mother was a minor's daughter.
And we all looked to try and escape from where we came from, to try and better ourselves. There was a driving force. I remember when we were youngsters in the late 1970s, people used to say say to us, if you don't get a a job when you leave school, you'll be on the scrappy for the rest of your life. You know, I can imagine telling people that now there' be all kinds of, you know, things going on. But anyway, back then they used to say what they thought. And so there was a sort of a driving factor for us to go out there and achieve something in life. You know, me brother-in-law did, me sisters did, I did, you know, so I'm quite pleased really.
But yeah, it's this giving back to life. life's been really good to me and I wanted to give it give something back and that's why I really got it. I was interested in the apprentice training. I found that the most satisfying of all the stuff that I' that I've done. I've done a lot of stuff.
I've traveled all around the world. I've done all kinds of different uh engineering jobs. Had all kinds of roles, you know, everything from, you know, an apprentice to director of a company and what it's about.
And the strange thing is as you when you're a director of a company I some of you probably may have been directors or are directors of companies. What you find is that if for example if you're an engineer when you become a director you become more of an administrator. You do less engineering.
You do less engineering. We had to do everything. When we set our business up there was three of us and you had to do everything. So you had to learn very quickly. And we were fortunate that we we'd got some really first class, you know, tax accountants, advisers, and that and you know, we've got people who knew about even back in what 95 when we set the business up, people who knew about the internet and things like that.
And they they came along with us all the way through our our journey. So that was really that was really good. But I can tell you all kinds of things about business and some of the experiences that we had. But I just wanted to just take this few minutes just to say thanks to everybody who has subscribed and I hope that you really do get something out of the out of the channel. Getting lots of subscribers and likes and things that isn't isn't the purpose of the channel. The purpose of the channel is to pass on information to give people the opportunity to do something with themselves with that information. If it helps people, that's the benefit. if it doesn't help people, they've had a chance to look at it and and view it.
So, thank you very much. Anyway, all right. What I thought we'd do today, it's still quite warm out here, actually. I thought we would have a look at just some of the projects that we've been looking at recently. And one of the recent projects that we did was the what we started work on was this little block for the power hacksaw. So, we could fit this in place of the vice and we could cut off these big bits of steel. Well, all I've done so far, and I've got video footage of this, so I'll put a video together when I've done a little bit more. I've machined the two sides here.
Now, there's two sides here are done.
You saw them. Done some heavy work on the shaper. And we did the two edges here. I've done that. You haven't seen that yet. And we've got to mark out, drill, and tap. We got to drill the holes for the four cap screws that hold that to that. And then we can try it out cutting through these big bits of steel here.
So that's where we are with that. Some of the comments I've been reading through as well on the uh on the website.
And Chris was asking us about the cylinder and the force it can generate.
Well, this cylinder here, I've got it written down actually. It's a 200 bar cylinder. So, what's that? 2,900 PSI thereabouts. Good enough in it.
This will give a thrust at 2,900 PSI or 200 bar of just shy of 2,000.
Just shy of 2,000.
It's spring return.
Right. I don't know what the spring stiffness is.
So if you've got this going full stroke, you've got Hook's law, which say for every inch, you've got to multiply the spring resistance by.
So, for example, if it's if it was £10 for every inch and if it's a 4 in stroke, you'd have £40 to get it down to full stroke. So, we'd have to take £40 off the 2,000.
I'm not sure what it is. I don't think it's going to be too much.
Anyway, that's our cylinder. It's quite substantial, but it's only 2,000. I think it's only Is it 30 mm ball? 35? I can't remember now. It's not important.
All right.
Someone was asking why not use the milling machine instead of the shaper as well. I know I'm a machine this block. Just put it on the milling machine. Well, if you've been paid to do it, maybe that's what you would do.
You probably do quite a few operations in one setup.
But we got this little shaper here. And I like using the little shaper. The tools are really basic and simple.
Just grab some of these tools here. You know, the bits of highspeed steel, quarterinch highspeed steel. I can sharpen them no problem at all on the off hand grinder, the oil stone. Or I can use me little uh warden tool and cut a grinder there on the bench.
If I've got if I decide to use the milling machine, we can put a fly cutter in. I don't have a fly cutter for that.
We can make one. And we could use single point tools like ones I've just been showing you, which is great.
Or we can use we could get a face mill or something like that with the indexable tips. That'd be great. But your problem with them, they're getting quite expensive now. Carbide's getting expensive.
I was talking to one of our suppliers I just show you something.
When would it be? Way back in March.
Back in March. I was talking to one of our suppliers cuz I bought a load of I got a load of chucking remas I bought here. The good ones as well. Dorma ones.
Imperial ones up to about half inch.
And when I went to get them, I was stunned at the price of them. Really expensive. It was, you know, it was probably about £320, something like that. I think I got a 1/8, 316, 1/4, 516, 3/8, 7/16, and 1/2 in.
Wow. I mean, Dor a good a good good manufacturer. Good good quality. you know, I probably never buy another one again. But when I was there, I was talking to to the lady who runs the the place, and she said to me, she says, "Next the next month, so that would be April, there were going to be price increases." Um, no surprise there.
But she was saying that carbide tools were going to be going up between 15 and 20%.
For them and she cited the fact that a lot of the carbide is controlled by China. No surprises there e.
So I just thought I'd mention that. So when you're looking at using the milling machine, you know, if you're going to if you're going to make general blocks, if you're using carbide, you know, you start wearing tips out, you need to get things replaced, it's going to start getting expensive, I think.
So if you can use other machines that you've got, like the shaper or the planer, you know, there's a little bit of a benefit there. Certainly for the home shop, if you're working in industry, you're going to be pushing your machines to your maximum and you will be including the cost of your tips in the cost of your jobs. You've got to you can't not do that cuz you ask who's going to pay for them. You going to pay for them instead of, you know, telling your customer that you got to pay for them. I don't think you will. You won't be in business long.
So, there we are. The Shaper simple machine, not as quick as the milling machine, but it can certainly remove the metal. We've seen that it can do a nice job. Gives us a good degree of accuracy.
This is a a nice finish.
And so does the milling machine. But the milling machine, the cutters, they're expensive. you need to get them or you need the equipment for to sharpen them properly or you need to be able to have a supplier who can sharpen them for you or you're knackered.
You could use a fly cord like we said earlier but anyway there we are and we use a shaper cuz we like the shaper.
Right. Where's my book?
Right. Tender. Yeah. Someone was mentioning about the axles and the original axles on the original locomotives. They were actually tapered.
The bit between the two axle boxes that the axles were tapered. And I'll just show you what I mean. I've got two choices with these axles. I can do the original design which came with or which I was generally working to or I can do the Don Young design which is the one here. And the Don Young one has a tapered axle. Can you see? See how it's tapered towards the middle?
Yeah. The Hotspur one, which was the original one for the Super D, the axles are parallel. He doesn't taper them at all. And it may be that some of the tenders didn't have tapered axles. It could well be that. I don't know. I haven't looked into it in much detail, but I haven't decided which one I'm going to use yet. I don't know yet.
We'll see about that.
There was another comment that I saw which was from our friend John Padet and he was mentioning about the ML7 compound was when I was turning the profile on the wheels for the tender.
Remember them?
Yeah. John says you can't you couldn't swing the compound round for the 20°.
You can't do that on the ML7. I thought that's strange. I thought they were the same. Top slip and compound. Well, they're not. I've just looked on the on the internet. I checked on Tony Griffith's website, www.laz.co.uk, and he's got some really good photographs there. And I'll just show you cuz there's something else I just wanted to mention about one of our viewers, Chris. He's putting a he's put a DRRO on his lathe, his super 7. It looks really nice installation, but he hasn't done anything with the compound yet. And I just want to show the compound.
If you want to do it on the compound, you're going to lose some some of your uh functions. Let me just show you.
All right. As you can see now, we buy the lathe. This is the compound here.
I'll bring you in closer and just explain what's what. All right. This is the compound on the Super 7 lathe.
Okay, it's obviously the cross slide.
For me to rotate this compound, I need a 3/8 spanner and do the two square headed bolts, one either side.
Yeah. And that allows that to swivel.
It will come all the way around.
Actually, see, you know, you can go all the way around.
It will go 360.
I don't do that cuz I want to show you something.
Always careful when I rotate that. The reason being, let me show you. In fact, let me take that tool out as well. We don't need that in.
Just put this away and I'll show you what I'm talking about.
If you've got the DRRO with a linear transducer in in here, got a linear transducer in here on the cross slide. That's what the three screws are there. And it's an enclosed one.
You got a cable there. Can you see that?
That cable.
And it runs I runs just over in a groove just over the gear.
You got to be really careful with that.
If you wanted to take this off to bolt something to the cross slide to line bore it or something like that, you you'd have to disconnect the cable. I mean, pull it. It's it's a nightmare to get out. You disconnect it on the plug at [clears throat] the back of the DRRO.
I don't particularly want to, you know, want to do that.
So, you can't do that.
So, just bear in mind if you wanted to put the linear transducer inside, you may restrict one or two things that you perhaps want to use your machine for.
But as far as the difference between this and the ML7, the ML7, the casting, this round casting here is bigger. Comes around like this on both sides. And it's got a curved slot. So you could only ever rotate that to the dimensions of the curve, which I think is about 90°, John was saying.
So you you can't go more than 45°.
So, if you wanted to screw cut, you couldn't set your tool over at 30.
You couldn't do that. So, you'd have to do it a different way.
So, there you go.
So, that's the thing about the linear transducer on the compound. It's useful.
In fact, it's useful if you're turning tapers and things like that. And I use it when I'm screw cutting too, just to be sure that I get things set correct.
Just tighten that back up. We don't forget it then.
So there we are.
I might take this off anyway and just give that a good I just lift it out and I I give it a good soak in with oil inside. It gets into all the areas.
All right. Well, there we go. Let's have a look at something else.
All right. We're by the Harrison mill now. And someone was asking about the the head, vertical head on the milling machine. Will it swivel around 360?
I presume it will. It's got degrees all the way around here. But I can't see way why you would actually want to do that.
I mean, if that just swung around like that, 45 either either way, you'd probably find that would be sufficient. I mean, there may be instances where you'd want to come around perhaps say 90 degrees, but I can't really think when you would want to do that. you'd probably change your setup to allow you to do that with a more conventional position for the for the head. What you got to remember is when you swing it round up here that comes [clears throat] around so it swings around it's up here. The head is up here or the cutting tool is up here.
You've got to get your work to that. You can't because that's in the way. So it's impractical to do that.
I think they do. It's easier to manufacture it so it can completely rotate rather than it can only rotate a certain certain angle.
It's just simple to do that. And of course, this here is the dowel which locks it in the zero position.
And interesting, this machine here is actually a universal milling machine. I don't know if I've gone into any detail with this milling machine. It's a Harrison mill. It's a late one. It's a late Harrison horizontal mill. That's a horizontal universal mill.
And there's one particular feature on this milling machine which makes it a universal milling machine which I'll show you. Right. Let me show you then.
Okay.
The feature [snorts] that makes a milling machine whether it be a horizontal or a vertical one a true universal one is the table.
The table on a universal swivels.
This one will swivel 45 that way and 45 this way. And there are two bolts, one at the front, one at the back. The strange thing is this particular milling machine is a late one. Okay. So, it's slightly different castings. You see the one that Carl Wilson's got? His is an earlier machine, but this is a later one. My castings are more square on this, but it's this is an imperial machine according to the little plate.
It's a little plate down here. It says threads UNC UNF. So, they're all unified threads.
And the unified thread, believe it or not, is a true international standard.
And we could go into that sometime in the future. But anyway, lots of these bolts on here are metric.
[laughter] For example, the locking bolts [clears throat] for the for the knee 19 mm cross flats for 12 mm locking bolts at the front. The locking nuts at the front. The table are 19 mm.
One at the back is always the awkward one to get at.
It's always in line with the col.
So, let's see if we can get it.
Might get it.
No. There we need to Let's go get a old 16 spanninner.
So, I thought I had a short cut down once somewhere. Might have it in this box. And that's what you see in this blue box. Sometimes when we've been on the milling machine, this is all the bits for the milling machine here.
There you go.
Okay, that's free to move now.
Just put that there. Let me bring you down and you can see it moving.
Okay.
Right. You [clears throat] ready? It's this feature which makes it a universal milling machine. Okay.
Here you go. See, the further you come around, the more restricted you are with its operation.
If you're trying to drive it on the X-axis, you're going to get things clashing and it'll stop the travel.
See, just hit the handle here down.
See, that's what makes it a universal milling machine. So, what it allows you to do is things like helical spirals, you can thread mill, all that kind of stuff.
You can cut scrolls on here and all kinds.
It doesn't take much to reign that as well.
You can set that up. No problem at all.
Just put a dial test indicator on on a face. Take that off. We can leave that in actually cuz that's that's actually set with the key in that is. But if we wanted to do it properly, we would actually clock this in case there's an error in that. But there you are. That's the um that's the universal feature.
Other features that we've got with this particular machine is we've got the vertical head.
Okay, you you've seen that. We just talked about that. We've got the vertical head which will come off and where the input is to the vertical head is where the horizontal ar will go.
That's where it goes in there. Yeah. So the horizontal ar will go through there.
We've got the over arm in the corner down there. See that big casting there?
That gray one.
This one here.
That will go on there. I've got the bearing bracket. We've got some arbers as well. So, we could set that up if you wanted to do horizontal milling. No problem at all. And I've also got the slotting head down there on the floor behind the planer. So, we could put that on if we wanted to. And it's a proper That's proper Harrison one. All these things are proper Harrison ones. I know Harrison made they stopped making these after a period of time. I think when they stopped making the machine and you there was somebody else made a vertical head. So you can get a you know a propri not a propriety but a an alternative vertical head for them.
But there you are. What I want to do with this machine is to I want to fit a little jib and show you.
I'll come around the side here and show you.
What I want to do is fit a jib on the side up here so I can put a little pull lift on or something like that. And I can use it to lift the head off, vertical head. I can put the overarm on.
I can put the slotting attachment on. I can put the vertical head back on. I'm not going to pick them up. When I was 21, no problem at all. But I ain't going to pick them up. Too heavy now.
So, we'll get ourel something knocked off. What we'll do, we'll probably get a piece of maybe something like inch and a half or 2 inch OD tube and we'll get a bend in it. So, it's quite strong and we'll put a little loop thing on the end, little hole for putting a the pole lift in.
But there you are. This is the uh the universal milling machine. The feed motor for the X-axis on the table is in a different position from the older machine. Let me show you.
All right. This is the feed electric motor. And that's the gearbox.
And inside here are the change gears to change the ratio or the speed.
Can you see them there? I'll bring you around so you can see them. Can you see them there? And I've got different gears.
So, we can change that ratios over over here.
Let's have a look.
You see, I've got different gears here.
So, we can change the ratios. We've also got the VFD, don't forget, so we can change the speed of the motor.
So, there we are. Them gears.
Just put this cover back on.
Very easy to change over. There's nothing special about them.
There we go.
When I got this, when I first got this machine operational, the motor wasn't working.
And so I had to strip it out. That's a pain in the ass. Comes out the bottom of the gearbox. Seals were knackered in it.
And what I found was the bearings were seized. Now when I stripped the bearings out, somebody replaced the bearings in the past and didn't do their ars from their elbow and they'd loited the bloody bearings in. And of course the lock tight had gone around the rolling elements. So the whole thing was just locked up. So I wasn't too impressed with that. And there was a couple of uh one of the shafts, two of the shafts, can't remember now. I changed the bearings on them and this side the gearbox. Pretty straightforward job, but I had to make a couple of little tools to allow me to do that. But straightforward enough. And we got it working. Okay. Now it does work. All right.
And inside, if you can see down there at the bottom, you see inside this cover here is the access to the electric motor.
I think the least said about that, the better.
It's not very nice getting in and out of there.
The milling machine has a digital readout on it on all three axis, X, Y, and Z.
This is obviously the control panel thing.
I got these from the the MDRO, same maker as the lathe.
DRRO, same make as the lathe. And they're from a company called Allen Dale.
They were pretty good. None of the brackets or not many of the brackets fit properly. I didn't like the brackets with all the the transducers and things on. So, I I did a lot of the brackets myself. I didn't didn't like the way they were. I don't like seeing things cobbled. So, the only diff if I was going to order one of these again, the only difference I would make I'd make the Z axis one longer so it came it finishes down here. I prefer if it was finished up here somewhere. That way, you're not going to get chips and stuff going down into here and through the top of the cover. But, it's not it's not an issue.
When I when I sized everything, I looked at what the stroke of the Z axis was. And I worked on that.
But then when I I got the things I realized, I should have gone a little bit more little bit more than that. But it allows I can sweep the whole distance. I can sweep the whole distance.
So, we shouldn't have a we shouldn't have an issue with that. And of course, the x-axis is okay, and so is the uh y axis is okay. But there you go. That's the milling machine. It's a universal milling machine. As we said, it's because of the table. It's the table that defines that. You can do all kinds of fancy stuff on this.
I'm going to tighten that table back up.
Now, before I forget, there's one other feature on the Millie machine, which we haven't mentioned.
That's me. It lights here.
I haven't got it plugged in, but this was a It's not the proper one that came with the machine. It's just a one I got from RDG Tools. No idea what make it or anything like that. It just looked like it was uh the right kind of light for the mill. So, we put it on.
So, there you are. That's the milling machine. You know what a universal mill is now.
All right, let's go and have a chat about what we're going to work on next.
Okay, what we're going to work on next is this the block that we shaped on the shaping machine. We're going to do some drilling, tapping, [clears throat] what have you, and we're going to get it fitted to the power hacksaw.
And then what we're going to do, we're going to cut these pieces off to length.
And then that job is done. That's been pending for quite a long while now.
So, we're going to get that sorted out.
And of course, once we've got that done, we can start finishing off the press. Then, we've got to bore one of them square pieces out. 4 in square pieces or put a thread in it or even thread it.
And we're going to thread this as well here. Cylinder.
Shouldn't take too much time.
I'll screw in.
And we got sort out connecting the little hand pump here to the cylinder.
We need to get a pressure gauge for it as well. It's important to do that.
We'll get a hydraulic pressure gauge.
It'll be glycerine filled. Always glycerine filled for hydraulics. Make sure you get the right kind. It's important. Hydraulic systems, if there's a pump involved, which there will be, you have to have some kind of a pump. They pulse. So, you need a gauge that can accommodate for pulsations.
Even your piston pumps, they pulse. Vein pumps, you might not think so. And gear pumps, you might not think so, but they do, they do get tiny little pulses. So you, what happens if you don't put a a glycerine filled gauge and there's no damping on the needle and it's doing this backwards and forwards all the time. And what happens is the board and tube it work hard and some snaps bang.
That's what the little rubber bung is in the top of a hydraulic pressure gauge on top of many pressure gauges. So if the board and tube smashes or if it's a diaphragm, if the diaphragm burst or whatever, then it just blows the rubber bung out the top and doesn't shatter the glass in your face. That's what it's for.
But anyway, we'll get a gauge for that.
I'll go and see uh my friends at Eurluid Power and they'll sort something out for me.
Get the make sure I've got the fittings and the hose and everything to go with with that. But anyway, there we are.
That's what that's our update. We looked at a few questions. We talked about 1,000 subscribers and covered quite a few little bits and one thing I always try and do and it's not too difficult to do because we we we have quite a number of questions that people ask or comments that people give and I think it's important to try and reply to them. Even if you just say thanks for watching, I think it's important to try and reply to them. I know some some uh YouTubers have got, you know, like half a million subscribers.
They must get, you know, 100, 200, 300, 400 comments. I don't know how they [clears throat] could actually read through all that. There's so much and do do all the other things that they're doing as well. Some people actually running a business, you know, so there's no way they could actually read the comments.
But I think it's important to make the to make the effort to do that. So, I always try and do do so. But anyway, I think that's enough today. I can go in the house now. It's a bit cooler in the house. I'll put together a little video for you of what we've just been talking about.
All right. Well, thanks for watching and I'll see you next time.
