Thread: Advice from the photographers.
22/10/2021 21:17:29

When I digitised my 35mm slides, I created a lightbox using 1/8inch white faced MDF board and containing 2 x 25w candle lamps. The viewing window was a translucent screen salvaged from an old 35mm battery operated viewer. This was used to backlight the slides. My camera is not the best, it is a Canon A640 so I experimented until I found an optimum distance at which the photgraphed slide almost filled the A640 screen. I then made a chipboard adaptor to hold the camera at a set distance, and using macro mode, once focussed, I found that I could whip through about 15 or so slides very quickly. Anymore than 15 or so and the light box started to get hot.

Once loaded into the computer from the camera, I used a software programme named The Gimp. First, I used a mode to correct the barrel & pincussion distortion introduced by the camera. Then I used a crop command to remove the black borders. Next I used a colour correction mode, to overcome the obvious deficiencies in the slides. Usually I used an "auto" mode. Finally, I used a paintbrush clone mode to overwrite those areas where there was dust, hairs, or in some instances, litter on the ground!

Occasionally, I found a photograph which was too far gone to be able to be retrieved. These had to be scrapped.

I did buy one of those fancy devices which allowed you to download onto the computer, but found it very poor in that the back lighting appeared to be a single source in the centre of the photographing area. This produced too much light in the centre of the downloaded copy which was not acceptable. The method outlined above, although not without deficencies caused by the camera, was overall much better.

2nd edit.

Guess what, I've more or less repeated what I sadi in the thread Nick has referred to. Sorry about that.

I bought one of these in 1995 when I lived in West Yorkshire. A few months later I moved to West Cumbria and managed to shift it by myself. I used a small trailer as transport for what was left after after having removed as much as I could first (tailstock, gearbox cover, possibly compound slide & possibly leadscrew & apron, chuck & chuck adaptor plate - these items being reasonably easy to remove). All these bits & pieces, along with accessories such as changewheels, chucks, faceplate all went in the back of my car. I have to say I don't remember how I got the bed into the trailer, only that I found that I was unable to get it into the car by myself. I assume that I used the Haltrack hoist.

At the new address, I set up an overhead runway system using some scrap parts bought from work, mounted the Haltrack hoist, manual by the way, and managed to lift the bed from the trailer, run it along the runway and place it in position on a pre-built wood (possibly a mistake) bench upon which it sits today. All the bits & pieces were then re-installed.

I haven't moved it since, other than to install a pair of cabinet heaters for rust protection, and given my age, late 70's, I doubt very much that I will ever move it again. Mind you, I do have a pair of hefty grandsons living reasonably locally if necessary, and a pair of hefty sons living about 100 miles away!

I watched the recording this am. Not good, appeared to be jumping about between various subjects, and, sorry to say, sleep inducing. Anyway, the recorder's set up for the next episode. Perhaps I should watch it just before bedtime!

Agreed, far too many adverts.

Thread: Grinding tool bits
01/10/2021 10:43:19

HSS is hard: that's the whole point of it, and is the reason why it can cut other steels. And yes, it does take time to shape it.

Heat won't damage the HSS properties, indeed HSS was formulated to resist the heat softening caused by too rapid grinding of standard high carbon steel tools, eg Silver Steel.

I've never tried actual cutting of HSS, but then I've never had a 200mm long piece of it, but if I was, I'd use a 1mm thick grinding/cutting disk in, say a 5inch/125mm angle grinder. I have successfully cut old file like that, and then converted them into lathe cutting tools.

Might I suggest that you invest in a double ended grinder - they are not that expensive and will be better than an angle grinder. And they do have, as a rule, both a coarse and a fine grinding wheel - use the coarse for initial shaping and the fine for the final shaping. FWIW, I used a diamond disk on some HSS - never again, as I think I've damaged the diamond!. Also, although there will be adverse comments about this, some authorities recommend grinding on the side of the wheel in order to achieve a flat surface - whan all said and done, you will not need high pressure, indeed, a light pressure will achieve a smoother surface of the HSS.

Might I also suggest a book: Harold Hall's Tool & Cutter Sharpening in the Workshop Practice Series, No. 38.

Good luck,

Thread: Has anyone heard of this before…dopey dogs…
24/09/2021 10:48:19

Many years ago we had a full pedigree Golden Retriever which I used to walk. The owner of what used to be a farm before being surrounded by housing used to have a Jack Russell which invariably came out to create havoc around my dog. One day, whilst being walked and at heel, my dog snapped, spun on the spot, gave one bark, and turned back to continue walking as if nothing untoward had happened. The Jack Russell, meanwhile turned tail and ran as fast as it could back into the farm buildings. Golden Retreiver 1, Jack Russell 0.

Thread: Back to Imperial
17/09/2021 20:16:18

I'm 78, so older than Mick above, and I much prefer metric. Indeed, I find metric linear measurements much more understandable than imperial. Capacity measurements & weights are someway behing linear measurements, but slowly I'm getting there, and I don't want to go back. Indeed, the whole concept of imperial I find to be a recipe for disaster. Think pennies, shillings, pounds, what a rotten system requiring an in depth knowledge of the 12 times tables and the 20 times table. 100p to the pound is so much easier. Similarly, ounces/pounds/stones/hundredweights/ton's etc. requiring a knowledge of 16's, 14's, etc.

So, as far as I am concerned, although brought up as an imperial child, and am to an extent struggling with the visualization of the various metric quantities, I am slowly becoming au fait with it, indeed in some instances I already do think metric in preference to imperial.

It will be a bad day if we have to revert to imperial.

Ok Neil, many thanks.

Quite correct Michael, I do indeed live in Cumbria. Which is why once Neil was advised by Jason, I've not done anything about the offer in the email and am now waiting for something more, anything more, from Neil.

Incidently, has anyone received MEW308 yet?

Neil,

I have had a look at the header, both as "All" (I normally use "Normal" and as "Message Body As" "Original HTML" (I normally use "Plain Text". The only thing of note, to me that is, is that under Message Body as Original HTML, Thunderbird throws it out as "To protect your privacy, Thunderbird has blocked remote content in this message".

To be honest, I don't really know what I'm looking for.

If anybody wants to have a look at it, I can always Forward it to another email address. Would that help?

Another comment: on checking, the string of numbers I replaced by "x,s" - see my previous message - is not my subscription number as I first thought. Therefore, the number is: 05649018. Could this be some some sort of registration number pertaining to My Time Media?

Peter.

I have recently received an email from Kate Hall to the effect that there are going to be problems with distribution of the Print version of the magazine, and that an offer is being made to allow digital access until the supply chain has returned to normal. Instructions are given about how to set up digital access.

Now all that is fair enough, because let's face it, the news media are currently full of stories about insufficient HGV drivers and the corresponding delivery problems and hence shortages, but it still leaves me with a few questions.

Firstly, will I still be getting the Print version for each issue, albeit delayed?

Secondly, I use Linux Mint as my operating system. Reading the information on the digital version setting up screens, and going direct to Pocket Mags (which appears to be the method by which digital versions are created), there is no reference to Linux. There is reference to other systems, Windows v.10, IOS, etc, but not Linux. Therefore will this system work? FWIW, the web browsers I use are Firefox, occasionally Brave, and I understand that if necessary I can download & install Chrome (but don't really want Chrome for reasons of privacy - I don't trust Google).

Thirdly, on reading past forum entries, there have been at times problems with printing. Could someone state precisely how printing is supposed to work and in what format is the eventual file, eg pdf, jpg, or what? Indeed, how does one use this system?

Finally, I assume from Kate's email that this will be at nil cost to myself?

Thankyou,

Peter G. Shaw

Thread: 2D and 3D Cad Software Recommendations
05/09/2021 15:52:07

Brian,

Ditch Windows in favour of Linux. I use Linux Mint, but there are others. Updates are then done at a time of your choosing.

Despite objections to the contrary, eg the Linux fanboys who think that Windows programs and Linux should never mix, I use an obsolete Win 32 bit CAD program quite successfully under Linux using an intermediatry program called Wine. There are other CAD programs, eg QCAD which have Linux versions hence no need for Wine.

Similar to others here, I will not and never will, succumb to using cloud based software. Neither will I use Facebook et al and as far as possible I try not to use Google, DuckDuckGo being my preferred search engine.

I realise Linux isn't for everyone, and it does mean putting in some effort to get to know it, but in reality once over the initial learning curve, it becomes second nature. I certainly have no regrets over leaving the malign clutches of Microsoft et al. And for what it's worth, my desktop is setup in a similar fashion to the old XP desktop. (Yes, Microsoft did have some reasonable ideas!)

Regards,

Peter G. Shaw

Thread: Electric motor speed
05/09/2021 14:21:20

Fair enough Keith, you didn't say that and I assumed that your 5000 rpm was printed on the blade as a maximum speed.

Just out of interest I've had a quick look at my mains powered hand held tools and found that the rpm as stated on the labels vary from 3000rpm (an aging B&D pistol drill) to 10,500 rpm (a 5" angle grinder bought from Aldi). Plus the max rpm for the 5" angle grinder disks is shown as 12,200 rpm. So maybe your 10,000 rpm is indeed possible.

Peter.

05/09/2021 10:58:22

The blade speed will be a maximum for that blade, and must not be exceeded. Presumably because there is a danger of it breaking up. It is very unlikely that the motor will be running at 10,000rpm

Thread: They see you coming
05/09/2021 10:46:56

A long time ago I had a Montego Estate. I can't remember the exact details of what happened, but I ended up going to a national chain who were advertising a free brake check. This was whilst on holiday. As others have stated, I was eventually presented with a list of repairs amounting to a large sum of money. After a discussion, in which they said it's all or nothing, I said "ok, nothing, please reassemble".

Shortly after that I took the car to my local independant for its MOT which it passed. So I started asking questions, eg, "What about the leaky brake cylinders?" Answer: "It's not showing outside the wheels and we are not allowed to dismantle to check"." Well what about the thin brake discs?" At which point the garage owner exploded and said "Have you been to <national chain>". To which I replied in the affirmative. The end result was that there was nothing wrong with the car other than normal wear and tear. The garageman then went on to state that he gets a number of people coming in who have been to <"national chain"> and all had been fleeced.

25+ years later, that independant is still in business; is still doing MOT's, is still doing all my routine servicing, and none of the subsequent three cars have ever failed an MOT! True, the cars have had some occasional remedial work done to ensure an MOT pass, and have had the occasional advisory (which don't remain as advisories very long as they get remedied pretty quickly, but that's just me).

The moral here is to find a good independant and stick with them. They will repay you by giving good, honest, reliable service.

Peter G. Shaw

Incidently, about costs and payments. I have found that by sticking with an independant, I am now in the position where I never have to pay when I collect the car - he sends the bill by email and I pay by bank transfer. Of course, I don't abuse that - I pay by return.

Thread: Strange stain in caravan
24/08/2021 09:35:54

Final (rather late) update.

Vinegar didn't touch the mug I tried it on, but since we were considering replacing them anyway (something like 25 years old, and one had splintered somehow internally) it's no real loss.

In respect of the sink, I used a cream cleaner originally from ASDA but really quite ancient (I believe it came with our previous s/h caravan, so could be around 25 years old) and along with a modicum of elbow grease, the stains were mostly removed. What's left is ok as the sink is not a single colour, but rather a faint mix of light colours. So thankfully, all's well now.

Thanks for all the thoughts.

Peter G. Shaw

p.s. Duncan, I do have a set of false teeth, and when I was given them (it) I said to the dentist "I suppose that means getting some Steradent now." The reply was "Oh no, don't bother with that, just use ordinary toothpaste - it's plenty good enough!" So that's what I've used ever since.

My last major purchase was two laptop computers. Deliberately I avoided Lenovo because I discovered it had Chinese ownership or something. Eventually I bought Dynabook, made by Sharp, I think. Now Sharp took over, biught out, dunno, the Toshiba laptop business so when I saw they were badging them as Satellite Pro, I thought good, they may be Japanese.

When they arrived, they had a sticker on the bottom - Made in China!

Seems like they are already here!
