Thread: The demise of the High Street
03/12/2018 18:40:10

As far as model engineering is concerned the town centre is no longer any use at all. When I first started as a teenager in the 1970s Reeves were in town, Kennions were too, although I never went to see them as living in Nottingham it was just too far.

Pools Tools were right in the centre of Nottingham, just a two minute walk up from Slab Square so tools were available easily. Cheap tools are available from Machine Mart and Toolstation, but branded stuff. or more specialised items are mail order or internet only.

Metal was a little harder as Carr's had moved out of town when I was very young and by the time I wanted them they were a 4d bus ride from the city centre, although as it was the same route as I used to get home from town, not too bad for me personally.

Even living in Birmingham as I do now there is only one non-ferrous supplier near town (Keetleys - V.Good) and for steel, tools etc it is always a drive.

The only metal one can guarantee is available in all parts of the country is the frighteningly expensive stuff that Homebase et al sell, and they are not always on a bus route in town.

PS I still work full time as well - does that count as a hobby??

Thread: Windows 10 again
30/11/2018 10:35:52

When installing any recent version of Windows it will select the most appropriate one for the computer hardware. Microsoft Office does the same. so unless you have any known incompatibilities 32 bit programs should all run OK.

One area to check though before committing yourself perhaps could be drivers for printers, scanners, input devices etc.

The laptop on which I am writing this has 6Gb of RAM and uses 32 Office in 64bit Windows 7 and several very old programs (pre 2004) all run fine. These were all the default options.

Thread: Washing machine motor
30/11/2018 10:28:28

At that age the motor almost certainly uses brushes.

It may not be single speed as washing machines do run at several speeds, but as for connections I have no idea

Thread: Drummond round bed and VFD

Getting back to the original question the issue boils down to a sensibly economic way of getting a suitable speed range.

Thanks Clive Just the kind of information that I was looking for - although as to whether the project is sensible or economic??? Very few of my others have ever been!.

Although the roundbed was originally introduced in 1908, the long bed version of the Drummond was announced in 1925 so the document was after that at least, and before 1943 when production finished, probably before WW2.

Michael,......Thank you soo much for posting that link/document, such superb vintage work. We have a lot to live up to. I particularly liked the 4.7inch QF gun model designed to fire .38 cartridges......can you imagine that now and what would happen next?

Possibly a court appearance and a custodial sentence?

Thread: Used Flexispeed
24/11/2018 22:28:03

Although they would fit I am not of course suggesting it would be the most suitable design to make on lathes of this size!!!!

24/11/2018 21:49:24

If you are looking for lathe chucks you can buy backplates and machine them to accept commonly available chucks - but if you are looking for tailstock drill chucks looking at lathes.co.uk they appear to be 0MT which are harder to locate.

As a simply built lathe it is possibly easier to renovate than some designs, but are these skills available to you? because paying someone else to do so could be expensive.

A fully equipped Flexispeed Meteor 2 sold on eBay earlier this year for £835. This for a machine at least 40 years old is probably about the same as it would cost to buy and equip a modern mini lathe - except you will have to search for and perhaps modify or make parts and accessories instead of walking in off the street and buying them.

As to whether it is suitable for the task you have suggested - probably, depending on the prototype you choose. Just checked the drawings for the 7 1/4" Tich and you could fit the wheels and cylinders on either lathe!

The mini lathe may have a larger capacity, but if the flexispeed is backgear equipped it may be more suitable for turning wheel castings if they fit on the machine. 

Go figure!

Thread: Drummond round bed and VFD
24/11/2018 07:06:30

Posted by Hopper on 24/11/2018 01:14:09:

VFD on a round-bed sounds like waxing a dirt floor. Especially if you already have a good functioning single phase motor. Might be more in keeping to make a double-reduction pulley between the existing motor and countershaft to slow things down.

There is no motor or countershaft with the lathe at present, so I was exploring all options.

As to the value of the task - of course it is not going to be the equivalent of a more modern machine, but then again I just like to see things put back into a position where they can do what they were originally intended to do. Plain stubbornness on my part I suppose, which probably explains why there is so much half working junk about the place!

Thanks

Main limitation will be relatively low torque transmission of the simple flat belt drive to the lathe spindle.

Were I to do the job I'd sacrifice originality by replacing the flat belt pulley drive with multi-vee ones which have much greater torque transmission capabilities.

Clive.

(Edited extract)

The lathe already has 3 step v pully so is no longer original anyway.

Thanks

The long term project (along with a respectable garden and a tidy garage!) is restoring to active use an early Drummond round bed lathe.

One of the shortcomings of the design is a lack of back gear - so does a 3 phase motor and invertor/vfd enable this to be worked round?

As Manuel in Fawlty Towers said 'I know nothing' so any info or suggestions greatly appreciated.

Thanks,

Nick

Thread: How to fit a taper pin?
23/11/2018 18:13:50
Posted by ega on 22/11/2018 10:30:00:

Do you mean the kind of SDS chuck supplied for use with hammer drills? They are typically of 13mm capacity and, I would have thought, rather chunky for this delicate application.

Incidentally, my SDS chuck of this type has a splined bore rather than a shank.

This is the one I bought from T***station - almost 5 minutes drive from here - I said quick. Works fine.

Thread: taper pins
23/11/2018 13:33:17

eBay sell el Cheapo ratchet tap wrenches that I have never found much use for tapping as you can't back the tap off to break the chips, but for small reaming jobs they do work OK (but don't expect them to last forever!)

Thread: How to fit a taper pin?
22/11/2018 08:49:10

Quick and dirty tap and small reamer holder - blank end arbour to fit your tailstock bored to fit the shank of an SDS drill chuck.(Nominal 10mm but may be slightly under)

Thread: Hollow Stays
15/11/2018 18:52:43

Looking at a boiler drawing (7 1/4 Tich) I was wondering why model loco boilers have a hollow stay for the blower. Is this a feature of full size boilers? as a simple pipe from the turret seems a far simpler solution.

or am I missing something vital??

Thread: Win 10 updates (again)
06/11/2018 22:18:07

Like many other people here my experience with desktop computers goes back to the very early 1980s and mainframes for 10 years before that. As someone who has been involved with computer/IT education for most of that time I have come to the conclusion that Windows PCs will work well when regularly updated running programs that are similarly kept up to date. Windows 10, as pointed out by a previous poster, works best when kept online so updates are downloaded when they become available. Yes things go wrong with updates and things get broken - but it is usually the up to date ones that get fixed first. What it is not easy to do reliably is to maintain a Windows PC in the past with an old operating system or one not updated to run old software. Things like antivirus or drivers can very quickly become issues.

My experience with macs is that they are far more able to be preserved in the past with a previous version of hardware, running a previous version of the operating system with previous software than a Windows PC. I have here a totally reliable PPC mac mini with Microsoft Office that runs well - and my Macintosh SE/30 would be similar if I powered it up more often. Modern iMacs at work are similar running their own software reliably, but having issues with updated versions as Apple updates can cause problems that are very difficult to resolve as they can make demands on hardware that cannot be met.

As a Linux user since 1995 (Slackware on 23 floppy disks!) It seems to be the most reliable system but it is very definitely not quite a consumer level one yet, and if your program is not available for it then you may be out of luck, although some of the emulators like WINE are quite reliable. I have a Linux based webserver at work that has been running fro more than three years, updated and upgraded when I remember to do it. It just keeps going.

My suggestion based on experience with many many computers is that if you run Windows keep it and your programs updated - it will break from time to time but be fixed quite quickly. If you take the Mac route you cam preserve your machine as it was when you bought it, but if you do update it, it can be broken beyond repair and that Linux works the most reliably - if it works for you at all.

Incidentally my abacus has never given a moments trouble and will still add up accurately and the drawing board that I used at university in the 1973 still works - is there a moral there?

Thread: Old Printer Parts
02/11/2018 08:20:48

Posted by Rod Ashton on 01/11/2018 18:20:10:

Excuse the aside but - Any of you printer guru`s know of a driver source, for an old pen plotter please? Parallel port type

Try here http://www.winline.com/evalpen.html they seem to support most HP plotters, but not tried it myself - my last plotter is still in the attic gathering dust!

This is a quite expensive paid driver, but I have been told that it works well - there are other free drivers on the web, but these all seem to come with 'update all your drives in one go' software that I don't want on any of my systems.

The HP site still lists a driver but for Windows XP only.

Thread: injector drawings

Two other sources are LBSC 'Live Steam Book' - an idiosyncratic description as you might expect, but early LBSC so less so than later perhaps and also Lawrie Lawrence produced a series on articles in ME in 1975 if you have access to the back issues.

Lawrie said he always had to open up LBSC's cones to get them to feed - but he doubted that Surrey water was thicker than Purley Oaks water, so that may influence your choice of reading!
