Thread: I honestly canít think of an suitable title
17/12/2020 11:32:58

I don't object to advertising, I just choose to avoid it wherever I can, but I do object to people covertly harvesting information about my browsing and shopping habits, and even more strongly object to people harvesting information from my contact list, etc. angry 2

I try to keep things as secure as possible but privacy doesn't really exist any more in the 'digital age'.

Thread: Windows 10 latest offering
18/11/2020 22:27:14

Just a word of warning to anyone thinking of buying one of the cheap mini-laptops available for around £150. Some of these have only a 32Gb SSD as the primary drive and 4Gb of RAM. Many people, including my partner, have found that Windows cannot install the mandatory updates due to insufficient space on these machines, even though I moved all the installed apps/programs to the secondary SD card drive so that the primary drive only holds the operating system. The only way to update these would seem to be to download the latest ISO file and do a clean install.


Thread: The Raspberry Pi gets domesticated
02/11/2020 12:56:57

Reliability issues aside, the ZX81 was more than adequate for controlling something like a central heating system, with just 1k of memory and machine code I could understand. I was in the process of adapting one for an automated cattle feeder just before I gave up keeping cattle a few years ago, and the program used nowhere near 1k of memory.

The Pi sounds rather like a sledgehammer to crack a nut in such circumstances. It has as much RAM as around two million ZX81s and the processor runs about a thousand times faster disgust

But, if there was enough free time in my life, I would love to play around with a Raspberry Pi . . .

Thread: For the latest in PC fashion! (Anyone here with a Master's Degree?)
28/10/2020 08:33:19

Don't think they had degrees, but many of my ancestors were Master Primary Carpenters sarcastic

Thread: Bleeding hydraulics
07/10/2020 22:08:17

The workshop manual for my mini-digger says you should fully extend and retract all the rams several times to expel air after working on the hydraulic circuits. In a lifetime of working with farm machinery that always seems to work for me. I guess the seals are oil-tight but not air-tight.


Thread: Mystery Object ... This one has me beat
14/09/2020 08:34:03

Having followed this thread with interest, I just had a thought to throw into the mix: the flat shape of the 'anchor' suggests it might have been designed to build into brickwork, i.e. set in the mortar between courses. Probably way off the mark but the best I can come up with so far . . .


Thread: Hydraulic ram machining
20/08/2020 10:57:00

I seem to recall our local (U.K.) ag. engineers replacing a bent ram rod with plain steel as an emergency repair many years ago. No idea what grade of steel, and of course it needed regular greasing to prevent rust, but it lasted many years. Might be a cheaper alternative if funds are tight?

I had a similar shock recently when it came to replacing the tipping ram on a 30+ year old trailer, just about the same price as the trailer originally cost! But I was pleasantly surprised to find an exact (imperial) match for the original, and I have a usable trailer again.


Thread: Old School Drawing Exercises and 2D CAD
26/07/2020 13:07:03

Thanks for your answer, Dave. I genuinely wondered if it was a trick question and I had missed something.

I should obviously have included a rule and possibly a set-square with my T-square and compasses! For quickness I used the digital version (TurboCAD) to produce my 'approximation' of the drawing based on the assumption about the second circle, but I didn't use any of its other functions. Point D may be determined by the intersection between a parallel line 100mm below A-B and a 91mm arc centred on E. Point B is where this arc meets the line A-B. All other arcs were similarly centred as shown on my drawing. Incidentally, my coordinates for point D seem to agree with those mentioned in answer to Michael Gilligan's earlier question.

While none of this really matters here, it might have serious consequences in a real-life situation to make assumptions about missing dimensions on a drawing. No doubt someone will now point out some grave error in my work, on which I have now spent far too much time

Here's another challenge for you. All transitions are tangents, and the top line is horizontal.

Going back a bit to the 'simple' exercise, is it safe to assume that both circles are in the same position on the Y-axis? Although they appear to be, the dimension line does not pass through the right-hand one. I am genuinely interested to know if there is any way of calculating its position from the dimensions given, except that it is 24mm from the left-hand one on the X-axis. If you centre both circles on the same horizontal the exercise seems very simple using just T-square and compasses.

Thread: Box-Shifters and Quality Assurance
12/05/2020 10:06:55

Surely it's purely economics? If you want quality assured 'out of the box' someone has to pay for all the checking, setting up and testing throughout the whole production process. If you are on a tight budget you have to accept that you might need to do a lot of that yourself. We all have the opportunity to take the first option if we can afford it, but for many the choice is between the second option or nothing at all. At least there is usually the third option of returning the faulty item for refund or replacement.

If there were no 'box shifters' many of us would not be able to afford so many toys important pieces of equipment. Without Clive Sinclair, whatever you think of some of his products, we might have waited a lot longer before computers became so widely available. In the absence of cheap imports from the far east, second-hand machine tools would probably be even more expensive due to supply and demand.

In my early teens I developed a huge interest in all things mechanical and steadily built up a tool kit of my own. At that time there were a lot of cheaper hand tools coming from Spain, some of which I bought with my pocket money and still have to this day. Maybe I was lucky, but I would have waited a long time before I could afford the same items from the likes of King Dick.


P.S. I do have plenty of better things to do really, but I picked some rhubarb yesterday and I'm waiting for the rhubarb crumble to finish cooking . . . and by the smell coming from the oven I think it is done smiley

Thread: Startrite Mercury drill
22/04/2020 10:34:08

Since the consensus among those who actually own the machine corresponds with the measurements in the original posting my money would be on 5/8 BSF. The supplied nuts would appear to be wrong, as MichaelG and others suggest.

I never take anything for granted, but I can't think of any reason the makers would have chosen an obscure thread for such a simple device. A call to Machine Spares might clarify the matter as they do list most of the spares. ( I have no connection with the firm, not even as a customer )


21/04/2020 12:31:09

Can't tell you the size as it is completely missing on mine and replaced with a bit of threaded rod and nuts, but spares do seem to be available ( for more than I paid for the whole drill ) from Machine Spares Ltd.

Mine is actually a benchtop model but I believe the head is the same as the floor standing one, although there are several models, I believe.

Thread: Wow, what a battery
04/04/2020 10:26:49

Long before we were inundated with Chinese imports I was once very tempted to buy what was advertised as a "2MW Laser Pointer" sarcastic 2

Thread: What are you reading?
20/03/2020 12:14:49

A lot of earnest stuff so far, and nothing wrong with that, but for something a bit lighter I'm re-reading some of George MacDonald Fraser's Flashman books . . . also available as audiobooks on YouTube. One of the most enjoyable ways to learn some 19th century history smile

Thread: Holding End Mill on small lathe
16/03/2020 20:31:17

Having done a limited amount of milling on my C4 lathe, using MT2 collets in the headstock, I am genuinely puzzled as to why anyone would deliberately introduce extra flexibility into an even more lightweight machine than mine by putting a secondary collet chuck in the morse taper, moving the cutting point further from the headstock bearings for a job where rigidity would seem to be one of the most important factors.

I have also achieved quite good results with a MT2 mounted fly-cutter. Again, the rigidity is better close to the bearing.

There must be a serious 'down side' to morse tapers that I haven't yet discovered if so many people dismiss them so easily . . . dont know

Thread: New computer possibly required
01/02/2020 10:47:33

I have had two PCs and a laptop over recent years from It might be worth looking at their web site where you can 'customize' your own machine. They will also supply without an operating system installed. The only drawback is that, being built to order, you might have to wait a week or so for delivery.

No connection except as a customer.


Thread: Why does everyone disagree with you
30/01/2020 17:18:52

Well, I don't know much about angels but this thread certainly seems to have grown wings and ascended to a higher plane. Such erudition and eloquence is rare on the interweb; long may it continue . . . well, at least until the weather improves and the sheds warm up a bit.

As a 'farm boy' my knowledge and abilities are wide-ranging but generally lacking in depth so I do enjoy being prompted by such as MichaelG to investigate topics of which I was aware only as a few names and phrases.


Thread: Desoldering how to?
24/01/2020 12:54:51

If they are normally open switches you could leave them in place and just solder the leads for the remote switches to the pins. Hard to be sure but they appear to only use two pins of each switch so it should be fairly simple.

Thread: Havenít done this for a looooong time!
27/09/2019 20:12:35

One of my first lathe bodges was filing two parallel flats on the head of a cup square head coach bolt to make a passable tee bolt. It needed a little refining of the square shoulder to fit the tee slot without binding. Often it is irrelevant whether the nut is on top or bottom, although clearly not always the case.

Thread: How to repair old King Dick socket extension?
27/09/2019 20:08:21

oops! wrong thread blush
