Making a "C" Spanner & Modifying 6 Locking Rings

[00:00:02][music] >> Hello again and welcome to my channel.

[00:00:09]I'm Fraser [music] from Metal Working in France.

[00:00:12]I operate a little light engineering business here in Southwest France.

[00:00:16]More or more more or less in the middle of France actually, but we are called [music] Southwest France.

[00:00:23]Anyway, the project I want today I've got to make a spanner >> [music] >> similar to this basically.

[00:00:32]As you can see it's got a couple of keys in in here. It's just [music] to do up some rings and locking rings like this.

[00:00:42]I've got a I've got a series of these as well to machine. I'm going to machine a slot [music] across the middle of them to take this new spanner that I'm making. This one would work okay, but it's a bit rough and [music] ready. So I'm just making a slightly better one, one that will fit over these things [music] as well.

[00:01:01]And uh see how this job goes.

[00:01:05]If you haven't already done so, please subscribe to my channel and don't forget to keep telling people >> [music] >> don't forget to ring the little bell, which is down on the on your screen.

[00:01:14]That will remind you of any videos I'm making [music] or that I put on on the channel in the future.

[00:01:21]And obviously [music] if you if you haven't already done so, please subscribe. It does help me massively. And >> [music] >> if you can if you can bear you can bear the boredom of watching me machining these pieces and watch right through the video. Don't just jump through to the end [music] cuz you miss so much of the actual information of what I'm doing. It's okay [music] to see what's actually finished at the end, but I'm sure it'll be far more entertaining to actual actually see >> [music] >> how I do it and what I'm actually doing what what each part of the process is.

[00:01:56]Anyway, let's see how this job goes.

[00:01:59]So, the first thing that I've got to do is machine down this uh this bar uh to make basically to make the handle of the of the the spanner or C-spanner or whatever you want to call it. So, let's uh let's start off with this first of all, anyway.

[00:02:30]As you can see, I'm now putting a knurl on using a a knurling tool, which has got uh two two wheels with it, basically like a a diagonal uh slots in them.

[00:02:42]I'll show you that when the job's done.

[00:02:44]I'll show you the how the how the tool is actually fabricated. But, they're they're opposite directions, so you end up getting a diamond shape on the knurl at the knurl or gripping [music] edge.

[00:02:57]Uh It's kind of a nice effect, actually.

[00:03:00]It's and it gives it plenty of grip when you're if you're when you're using a a spanner or a lever or anything like [music] that.

[00:03:09]Uh can't run it very fast. It's going to be running fairly [music] slowly so that uh gives the tool a chance to work.

[00:03:17]>> [music] >> Going on on on the automatic feed.

[00:03:20]Put some coolant on it just to make sure >> [music] >> doesn't get too hot.

[00:03:24]Uh because obviously if it gets hot, uh something might seize up, and then I just get a lot of [music] ground up metal on the uh instead of a knurled edge.

[00:03:35]Uh we'll see.

[00:03:37]It's coming out okay, though. Looks pretty good to me.

[00:03:40]Uh pretty difficult [music] to tell while it's running, but uh I've got a fairly good eye, and I know uh whether it's looking good or not, normally.

[00:03:48]Uh it's cutting [music] well, actually.

[00:03:52]We're nearly at the end there now. It's not too bad.

[00:03:55]Uh as I was saying, it's quite a [music] slow process really compared to other machining aspects.

[00:04:02]But uh it's going on okay.

[00:04:07]We're nearly at the end of it now anyway, so and then I'll just need to clean up the edges so that it looks a little bit neater uh rather than because this does tend to throw up a bit of a burr on the edge of the um the edge of the steel.

[00:04:21]But uh it's coming out quite good actually. [music] It's not too bad at all.

[00:04:30]There we are.

[00:04:31]Now you can see that in all its glory.

[00:04:33]Nice diamond edge knurls. As you can see, the knurling tool itself I don't know whether I can get uh get the camera to to show you it very well.

[00:04:46]Uh I'll try and zoom in a bit on the camera and let's see how we get on with it.

[00:05:03]It's about close [music] as I can get to it.

[00:05:06]As you can see these [music] wheels have a actually a cutting edge on them. They're They're in opposite directions.

[00:05:17]What I can do is if I take the tool out I can then [music] show it to you by lifting it up to the camera, hopefully.

[00:05:26]That will show you how the knurl actually [music] works.

[00:05:32]See, these these wheels they have the uh actually just [music] the uh a groove cut in them in opposite directions.

[00:05:44]So, when you run [music] something through the middle, it it puts the diamond shape on it.

[00:05:53]So, I've just turned a little bit on the end here just to tidy this edge up a little bit.

[00:05:58]Not too bad. I've done this end as well.

[00:06:01]But, it's just to relieve the the burr it well, the burr on the on the knurl itself.

[00:06:06]>> [music] >> A bit bigger at this end because what I'm going to do now is I'll hold the the the thing in the in the jaw a little bit deeper in with some packing in it. And then I'll put a radius [music] on this edge.

[00:06:19]So, that shouldn't come out too badly, hopefully, with a bit of luck.

[00:06:25]A lot of this this sort of procedure is is based on not on luck so much, but uh just uh trying things out, uh making sure everything works properly together.

[00:06:40]So, now I'll just put a a radius tool on the end here.

[00:06:45]Put that on there, and then I'll wind this in till I get a nice radius on the end of the uh the handle that it well, it's going to be a handle like [music] a lever.

[00:06:57]So, that should be quite come out quite nicely.

[00:07:00]>> [music] >> I'm going to get that radius on there.

[00:07:05]There we are.

[00:07:07]Quite a nice radius in the end.

[00:07:15]All right. Once again, I'm going to be using the wobbler.

[00:07:19]Uh this is this little guy in here.

[00:07:21]Uh when it [music] kicks off to the side, uh you'll see it when it's running. I don't know whether you'll be able to hear me once I switch the machine on, but uh anyway, in the meantime, this thing will will level up first of all, and then it'll kick off to the side.

[00:07:36]When it does so, that [music] means I'm I'm exactly 5 mm away from this this edge of this thing.

[00:07:45]But, let's see how this [music] goes.

[00:08:09]There you go. There it's gone.

[00:08:11]Not too bad.

[00:08:13]Didn't take an awful lot of effort.

[00:08:15]That's fine.

[00:08:17]We'll switch that off.

[00:08:20]I can now elevate the take the quill [music] up.

[00:08:24]So, we take that away from the work piece. I'll zero the the dials on here. You can't the dials on here. You can't really see them from there very well. But, anyway, not to worry.

[00:08:37]So, then I'll just wind along 5 mm, which will give me the center line of this this uh the the quill on the machine.

[00:08:49]So, let's go 5 mil.

[00:09:03]There you go.

[00:09:04]5 mm. Now, we're on this edge. Now, I know that this uh this piece of steel I [music] have here this this tube is 88 mm.

[00:09:13]So, I now need to come to the middle of it, which will be 44. So, I need to come 44 mil. So, I'll zero [music] the the dial once again.

[00:09:25]And then we can go along 44 mm.

[00:09:32]It's a bit difficult for me to show you this actually working, but uh I'm afraid you'll just have [music] to take my word for it. But, I'm going along exactly 44 mil.

[00:09:44]We're at 43 now.

[00:09:46]Coming up 43.7. [music] Oh, too [music] far.

[00:09:55]I've gone a little bit too far. It's 0.015.

[00:09:59]We'll go back and then come in again.

[00:10:10]Here we go.

[00:10:12]That's in now in the middle of this of this tube.

[00:10:16]Yeah, it looks pretty good actually for the eye even.

[00:10:19]So, that's fine.

[00:10:21]And now [music] lock the table in place.

[00:10:25]And then we'll put a a center drill in first of all.

[00:10:31]So, I'll just remove that. [music] It'll come out.

[00:10:36]It almost wanted to stay in there for some reason.

[00:10:39]Right.

[00:10:40]That's the wobbler out.

[00:10:43]And now put a center drill in.

[00:10:48]Put the collet back in first.

[00:10:51]And I will need a big adjustable spanner.

[00:10:54]Uh a big spanner to to tighten this up.

[00:11:00]And we'll turn that down onto low speed so that we can get a bit more grip on it.

[00:11:08]Come on.

[00:11:12]And now we'll put a center drill in just to to mark this.

[00:11:17]And give it a bit more Take it back a little bit. Let it All right, that should do nicely.

[00:12:02]>> That's okay. So, we've got to start on it anyway. [music] And now I've got Now, I've already drilled these set this hole out to about 14 mil.

[00:12:12]>> [music] >> Now opening it out to 15 mil to take the shaft I made to go in there.

[00:12:47]There we are. That's quite good, actually.

[00:12:49]Nice clean hole.

[00:12:51]But, that's fine.

[00:12:53]I'll put the shaft in there and I will weld it weld it into position uh to make sure that uh doesn't it's not going to move.

[00:13:02]Just take this drill out.

[00:13:08]There you go.

[00:13:16]Okay.

[00:13:18]Now take that out of the vice.

[00:13:24]So, now as you can see, I'm I'm milling the slot in [music] this uh in this uh ring.

[00:13:30]I'm just taking half a millimeter at a time because I'm only >> [music] >> holding on the the shell side here. So, I can't clamp it very very hard to hold it. So, I'm just taking small cuts.

[00:13:46]I'll go down to about uh four, six, or eight mil in depth.

[00:13:52]Um and then we'll see what it's like.

[00:13:56]>> [music] >> I'm going to use a 12-mm key.

[00:13:59]Uh this milling cutter is about 13 mil. So, that'll give me enough clearance so that the uh [music] the key will fit fairly, you know, fairly good or fairly well [music] into the uh into this ring.

[00:14:17]Uh I don't want it to be slack, but also I don't want it to be too tight.

[00:14:21]>> [music] >> Otherwise, the operator won't be able to engage the key into >> [music] >> into the ring.

[00:14:28]Uh the locking ring.

[00:14:30]So, we'll see how this this goes. It's going to be a bit lengthy, so I'll probably put this onto a a time-lapse uh video so that uh we can see how it it how it progresses.

[00:14:55]Well, there you go. Another little job complete. There's the the key that I've made.

[00:15:01]It doesn't look up to much, but it's certainly going to do the job. There's the knurled handle on it. Then it goes into these rings.

[00:15:09]>> [music] >> As you can see, I've put a slot in there.

[00:15:12]So, that locks into that.

[00:15:15]So, it's ideal [music] to tighten those up.

[00:15:17]These ones I had to modify slightly. I had to just trim the thread on the inside. I've got a video that, I'm afraid. And then I put these slots in as well. On these ones, there are already four slots [music] in there, so I've I've just enlarged them and and they're all four all the same now.

[00:15:36]>> [music] >> So, they're all That's all locked in.

[00:15:38]That'll do it. That'll do quite nicely.

[00:15:41]Okay. I hope you enjoyed that video, and I hope you did watch right to the end and watch all the way through and see the procedure. Anyway, if you haven't already done so, please subscribe to my channel, and don't forget to ring the little bell up here somewhere, but uh down on your screen reminds you of any videos that I put on in the future.

[00:16:02]And as I say, don't forget to subscribe and follow me and like if you if you like if you enjoyed the video, and look out for more videos in the future, and look back at some in the past. There's some >> [music] >> very interesting stuff out there. But, in the meantime, I'll bid you farewell and see you in the next video. Goodbye.
