Thread: Install & commission of a Chester Cub 630 (Warco GH750)
22/05/2021 18:27:39

> One, use scaffold poles and plenty of them.

One of the problems I have is I don't have a chance to see this thing before it turns up, or get much more information about it. Scaffold poles is definitely one option but my worry is what's going on underneath the footbrake - I can see there's a bar of some sort but I'm not sure if it's there on both sides or how much weight it can handle should it accidentally end up supporting half the weight of the lathe.

> borrow a JCB

I did think about this, and yes, I don't think it would be a problem, but they can still only get me as far as the door, I think - that space in front of the workshop is big enough to get a vehicle reversed into but not for a JCB to do anything but drop the pallet in front of the door - which would still be a bonus, for sure! And I need a plan B anyway as there's any number of reasons I might not be able to get help for a day or three - apart from anything else it's still lambing up here.

In terms of lifting, it has holes to run lifting poles through (the small covers at the top of the legs of the stand), though helpfully the manual doesn't recommend a size.

> Can you take the splashback off

I hope so, and will if I can, but I don't know!

> Once in the workshop

Yes, this is the bit that's worrying me least at the moment - it's fairly level concrete and while it's tight it's manageable.

> I've also found it in a 2002 catalogue...so it may give you a clue on it's age

Thanks Nicholas - that's in line with what I thought. I suspect it was sold by both the hobby and professional sides of Chester, perhaps with different paint jobs - I can't find much on it on the net (and actually, I can't find anything of the alleged Warcop GH750). One thing I'm hoping is that the school that bought it originally didn't specify a smaller motor than spec, which sometimes happens.

> used some 40mm steel bar tapped m12 each end, to make four feet with adjustable swivel soles

I like the look of that, it makes a lot of sense. I'll have quite a bit of time once it arrives and I get it in, as I need an electrician to run a 3 phase spur (I'm lucky enough to have three phase on site, which came as a pleasant surprise) and replace the wiring in the rest of the workshop.

Thanks for the scan Nick, the list of accessories is interesting to see - that milling slide would certainly come in handy. I am hoping that the machine will take fairly standard sized accessories - though mind you, the D1-5 camlock seems to be relatively uncommon, so I suspect my first machining project is going to be an adapter plate for a 4-jaw chuck!

22/05/2021 15:52:41

So my first problem is getting it in place. It is being delivered by Palletline, so there's no telling how helpful the driver will (be able to) be. This is the entrance to my workshop:

img_20210522_134457414.jpg

and this is the view from the road:

img_20210522_134348687_hdr.jpg

There is a large area of hard standing to the left, not pictured. Palletline normally only guarantee a pallet jack on delivery, and while it is possible to get over the ground to the door - it's concrete underneath the moss, and we've done it before - I'm a bit leary about doing so with a 500 kilo lathe balanced on a Euro pallet. At the same time, I really don't fancy rolling it on scaffold poles over that ground.

Then the next problem is getting it through the door. I've measured: the gap in the door is 690mm with the door on; if I took it off, it's about 740mm. I don't want to take it off, but, 5mm clearance (width is 680mm) is hardly generous! Finally, once I am inside, I have a space that looks like this:

plan.jpg

The external door is at the top left hand corner and the lathe is to go in front of the window (the 1830 dimension is for a previous lathe I didn't go ahead with). The rectangle at the top right is a concrete shelf, the 3000mm is my bench and the smaller rectangle is my wood lathe:

img_20210522_134527357.jpg

img_20210522_134541260.jpg

At the moment, I am thinking: I need to get it on wheels to cover the ground outside, BUT ideally those wheels don't protrude out the sides to make it possible to get through the door. In addition, my turning space inside the workshop is limited.

Would it be sensible therefore to consider getting the lathe up on some dollies:

dolly.jpg

I am thinking that something like that, though higher weight capacity than this! Is it safe/feasible to do something like this? Would it be wise to bolt the lathe to the platform? Amazon have a 400kg dolly L590 x W290 x H140mm

Then, getting it off the pallet onto the dollies: Presumably I can get the lathe lifted up with blocks, wedges and a pry bar enough to get a round bar under it to roll it onto a dolly. Is there anything I should be careful about here?

Any and all other thoughts and suggestions very welcome!

After more hours poring over machinery adverts than I would care to admit, I have finally purchased one of these machines via Warco's used machines sales. It comes with very little equipment, sadly, but it is big enough to be bigger than I can imagine needing for my purposes - and so with any luck hopefully big enough! It has come from a school and has I am told sat pretty much untouched for most of its life so far. Little of the standard equipment - steadies, chucks, etc, seem to have migrated with it. There may not even be a chuck key.

I'll have in the fullness of time lots of questions to ask, beginning with getting it in place, but first, some useful info/links. The machine is a Chester Cub 630; I am not sure how old it is, but Chester deny all knowledge of it, from what Google tells me. Apparently Warco sold a GH750 which was essentially the same machine - at the moment, I don't know what "essentially" means. The lathe was manufactured in three sizes, 500, 750, and 1000mm between centres. Note that it's a quite different machine to the present Warco GH600.

TPH have a copy of the specifications here:

https://www.tphmachinetools.co.uk/products/1410-new-chester-cub630

300mm swing, 750mm between centres, 38mm spindle bore, D1-5(!) camlock, MT3 tailstock, overall length 1650mm, width 680mm, height 1200mm. Overall weight: 500kg. Three phase.

I have a copy of the GH750 manual (thanks Gavin!) which is not hugely helpful, particularly in regard to particulars of oiling and maintenance, but the wiring diagrams and so forth are worth having.

And here is how it looks: 2355.jpg

So that's the lathe itself - I'll do a separate post about planning the move.

If it's of any interest, Warco have just repopulated their page of used machines - one has already gone [waggles eyebrows] but there are a few Warco gearhead machines of various sizes at prices that might be worth not hanging around for!

Thread: Phone Caller ID does not work
03/05/2021 21:00:20

The problem is that as long as Plain Old Telephone Service still exists, the protocols underlying it cannot be upgraded, because they have to work internationally and also do all the tedious stuff like getting calls to the right place and make sure the right person gets billed, and an upgrade means the entire world must upgrade at once. Once POTS ceases to exist, and phones become entirely VOIP, the protocols to fix this already exist.

At a national level there are a few things that are being done: one is to block caller ID from numbers that are guaranteed never to originate phone calls, though how effective this will be I'm not sure. Banks and the like have no interest in solving the problem of identifying themselves to customers: last time I got a call from them, I picked up the phone to someone who asked "Is this Calum? What's the first line of your address? And the postcode?"

Thread: Club Constitution
10/04/2021 22:13:00

An Asset Lock is simply a term in your constitution that specifies what will happen to the assets of your organisation in the event it is wound up. Depending on whether you are a charity, CIC, standard limited company or a private member's organisation, you may already have some language around this. If you do, all you really need to do is make it clear exactly how assets would be disposed of: the "lock" means that the receiving organisation must carry on similar aims to your own organisation. No specific wording is necessary, just clear plain English!

Thread: There may be a delay in some deliveries ...

> Evergreen Marine is the operator and the ships name is Ever Given, that’s always going to be confusing, what were they thinking?

Well, how often do people not in the trade need to worry about the names of Suezmax vessels?

>I wonder how they managed to go aground in the first place.

Very good question, and I wouldn't believe any of the explanations proposed so far. Basically, big ships are incredibly tricky to steer in narrow channels - Suez is tidal, there are weird hydrodynamic effects at play, there is wind, and the guy steering is some underpaid, undertrained dude who may not speak the boss's language very well. Once something goes wrong, 160,000 tons of boat takes a while to arrive wherever it's going.

Winds and breakdown are very plausible explanations, but the thing is: the owners are right now looking at an extraordinary set of liabilities that will keep lawyers in fine wine for years. They will not be admitting that someone was asleep at the wheel any time soon, whatever the truth.

Thread: Was Draw Filing ever a chargeable offence in the RAF?
24/03/2021 22:38:14

I suspect Old Mart has it quite right. The other thing that occurs to me is that the military inevitably adopts different terminology to the rest of us mere mortals, so maybe some quite different operation was meant.

Thread: Brazing silver steel: any caveats/recommendations?
07/03/2021 19:19:23

Dave, yes, they're very happy to get their manufacturer (they don't grind themselves, which came as a surprise) to make it up for me, if I can commit to taking around five hundred metres of it. Bit much for my little operation.

06/03/2021 22:10:49

Thanks all, and sorry for the slow reply. Epoxy does make sense (I neglected to mention I'm drilling wood).

1m lengths would be ideal, and what I normally use, but 11/64" is according to my supplier "obsolete", which rather has me scratching my head, but never mind.

Gun drills would be ideal, but very much in the future!

Thread: Locating a copy of a CDROM for a C Compiler
06/03/2021 22:07:11

It can be surprisingly difficult to locate the necessary tools to run on obsolete systems. I do not think anyone provides gcc binaries for XP, and indeed I'd be a bit wary of thing that said they did. An install CD for an IDE like Visual Studio might be easiest to procure.

What you might want to investigate is "cross-compiling", compiling code on one machine for a different machine. It's obviously more difficult to set up, as you have to know the details of the target, but in this case I suspect it might be easier than trying to make an XP machine learn to code at its stage of life. There are lawyers younger than your laptop

Thread: Brazing silver steel: any caveats/recommendations?
04/03/2021 10:32:21

I'm doing some long hole boring with unusual diameters. I can get short lengths of silver steel, but not long enough, so I'm wondering about brazing them onto a suitable shaft. Has anyone had any experiences of this? The shaft would have to be "pretty straight" but not "machinist straight", as the bit will centre and direct itself.

Thread: Looking to learn CAD
19/02/2021 17:14:22

I was wondering when someone would mention OnShape! My last experience of CAD software was AutoCad, back in the late 1990s, and I've tried nothing else since, but my experience with OnShape has been very good: it works well, seems bug free, and the documentation is excellent. I was a bit suspicious of having an entire CAD package running in the browser but it feels effortless, and my desktop machine is not that up-to-date, either.

The designs being saved publicly will obviously be offputting to some, but I find it easy enough to make up nonsense names for anything I feel proprietary about!

nearly at my wit's end and thinking it may be easier to scrap the lot.

Much as I am tempted to agree and turn up with a trailer and helpfully take it all off your hands for a very modest fee, I suppose we should be honest and admit that in the grand scheme of things electrics are a relatively minor, if necessary, part of the whole business. Even if you had no motors or wires or other electrical stuff you'd still be better off than many of us!

Thread: Cookies and similar ...

A VPN removes exactly one of the identifying attributes I mentioned: your IP. If you want to obfuscate the other pieces of information, you have to use a VPN service that does so automatically or you have to configure it yourself.

> If you use a VPN, you're among around 31% of internet users

While that's probably a fair reflection of total internet traffic, I doubt it reflects the average internet user in the West.

At the end of the day, almost every website of interest requires you to identify yourself to it and re-identify when you visit again, so there is only so much that paranoia can save you from.

Of course, cookies, like most things, can be used for nefarious purposes

On top of this, it is worth knowing that almost every user on the internet is uniquely identified by your IP, browser, operating system, and other information that is sent by default to every website on the internet. If 'they' want to know who you are, it's not a problem for them.

27/01/2021 15:27:06

The initial screenshot shows "Website Data", not cookies. I am not up to speed on the details but there are now other mechanisms for storing information on your computer than cookies. In theory, of course, all to your benefit if you are not having to download the same thing over and over, but who knows?

Great news Neil, and no doubt thanks for applying a little pressure to grease the squeaky wheel!
