|Thread: Railway station toilet signs|
I remember the contrast between the British and French trains on a school visit to Paris, The train to Newhaven was comfortable sprung upholstered seats and the French train from Dieppe had wooden slatted seats rather like a park bench, the loo was interesting as it obviously dropped straight to the track with a flap to control the draught should you need to be seated during the performance. The Metro was a contrast the other way as the introduction of the pneumatic tyred trains had begun and they were super smooth and quiet compared to the London Underground.
|Thread: Diminishing chocolate bar|
Sainsburys were out of stock of 4pt milk and had no substitute available, it seems hard to believe.
|Thread: Buy a book or download free|
It was reprinted a year or two later so I suppose anyone who paid silly money for a copy would be kicking themselves.
There was a period when Ian Bradley’s Myford workshop manual was out of print and second hand prices rose to silly levels. The original Myford who never embraced internet selling had stock of the book and were selling it at the cover price so I bought my copy from them, still enjoying my bargain.
Just because a download exists on the internet does not necessarily make it legal to download it, much material that is protected by copyright has been posted in various places on the internet. Of course the chances of being pursued for an illegal download are very slim, most effort is put into prosecuting the hosts of illegal material much as happened with the music pirates. Artistes now receive minuscule reward from hosting sites and now earn a living by touring. I do think that material that is covered by copyright but is out of print and only available at inflated prices on the second hand market does have a weakened argument for protection but they always have the option to reprint if demand grows. Much interesting material that is out of copyright is available in various places and is perfectly legal to download.
|Thread: Concrete Panel Garage/Workshop|
I built my fence with concrete channeled posts and concrete gravel boards, the panels were 1.8m and the gravel boards 6ft, the panels are too narrow and I had to add the missing inch to the panels to make them fit securely. If anyone is taking on a fence project then check the sizes. I imagine there will be a few fence projects in progress after the winds recently.
|Thread: Hand Hacksaw|
I remember the three turns after taking up the slack, my Eclipse 40PG with the pressed steel pistol grip is plenty tight enough at only two turns, the 1970s tubular frame one struggles to ever feel taut and the tubular frame easily takes a permanent set.
|Thread: Model Engineers Handbook|
My father was a Freemason and my boss of many years, they are two men who I have the greatest of respect for as decent honest men. After my mother was widowed the lodge almoner kept in regular touch and although she was never in need of any assistance from them they are always there for you. Masons being ordinary people are subject to the same failings we all have. I remember by boss who was responsible for interviewing prospective candidates for the electrical department telling me a candidate had signalled his membership to him which in that situation is forbidden, as you are not to use freemasonry to your personal advantage, it did not go well for him as he got an extra rigorous interview and was not offered a job.
|Thread: Carbon Steel vs HSS Taps & Dies|
HSS are ground thread as I think it would be difficult to make them any other way, this has the advantage of being able to produce a very accurate thread but that will depend on the maker. Carbon steel can make very good taps and dies but here you need to buy good quality and many carbon steel taps are poor quality as the makers save every penny they can on material and machining. If you are going to produce a HSS tap then you need to invest in the machines to make them and a higher cost material so it is probable that a budget HSS tap will be better than a budget carbon steel item. With the demise of most of the old brands that could be relied on to be a good quality item made in carbon steel and HSS being the material used by the well regarded brands today the idea that carbon steel is inferior has prevailed. The picture is becoming a bit cloudy now as some HSS taps are not as good as they should be and some carbon steel are excellent. Shopping for HSS or CS at the extreme economy end of the market is likely to be disappointing but some people will strike lucky and get a bargain.
I have actually tasted Bakers Fluid, it was not a gourmet experience. It was only a tiny splash but it is a particularly foul experience, I suppose it was marginally better then getting it in my eye but I strongly recommend not tasting it, and it takes a lot of rinsing to get rid of the taste, I don’t remember it doing any real harm but I was rinsing within seconds of tasting and didn’t swallow any. Petrol is another taste that I find difficult to recommend, I had a rather larger sample of that trying to prime a siphon.
|Thread: Hand Hacksaw|
I have three hacksaw frames and my favourite is an Eclipse but so is my least favourite, my favourite is an old pistol grip frame with a rigid flat bar frame, my least favourite is the tubular framed Eclipse from 1973 when I purchased it.I also have a Ding Dong frame which is not bad but fairly heavy, I understand that Ding Dong blades were rubbish but the frame is not bad. I prefer all hard blades if I am sawing work that is rigidly held but if I am sawing conduit in a site pipe vice then it has to be a flexible bimetal blade. I mainly use Eclipse and Sandvik(Bahco) blades but Starrett seem to be very well regarded but rare in the UK.
|Thread: Number stamps quality.|
A set of stamps in the factory had been used to stamp hardened steel, they do not survive that sort of treatment. I would have thought the owner of combination set would have understood that the rule is hardened but their initials are stamped on it, rather shallow indentations though. I must say I hate precision tools being marked but in the factory they used an electric etcher to mark tools with a calibration ID mark.
|Thread: Precision ground flat stones in UK?|
I would think that unless you have the means to maintain a flat stone then it will become just a stone fairly quickly, they seem to be used for rather high quality toolmaking and if you are in that line of work then a surface grinder will be available. It may be more realistic to look for a tool room who use these and see if they could do your stones when they do theirs, I would imagine that a surface grinder will not have a diamond stone mounted all the time and they would set up to do a batch now and again. A poor man’s version could be a sheet of fine wet and dry paper on a surface plate but that would be difficult to handle if you just wanted to check a machine table or indeed the surface plate itself.
|Thread: Number stamps quality.|
Pryor were a big name in number letter and number stamps. I am not sure whether they are still in business.
It looks like they are still around Pryor

|Thread: Songs about Engineering|
this is a bit about Glen Campbell and some of his session guitar work
Glen Campbell was not only a good singer, his guitar playing skills as a member of the session band the Wrecking Crew were superb.
A schoolmate of mine fitted the rear wheel from a small wheeled Moulten bicycle to the rear of a standard framed bicycle, to recover the required ground clearance to pedal the creation he cut the rear downtubes off, bent the lower fork down and bolted new longer downtubes in.

|Thread: Is there ever a time to let politics come into the forum|
I suspect most of us will be in broad agreement on the subject of Ukraine but this is not the place to discuss it. I think it is best to lock this thread while we are all still friends.
|Thread: Calculating Mount Point Speeds|
An air powered pencil grinder can run at 60,000 rpm and is a useful tool for small mounted points, buying one specially to run some free points rather negates getting a nice freebie. I would use what you have to run them until you have used them up.
|Thread: stuff that came with my lathe ...|
I would not part the metric conversion set from the gearbox even if you think it unlikely you will use it. The 4jaw is a definite keeper as it is the most versatile chuck and can hold any shape of stock material and many irregular castings, each jaw is reversible independently which can be useful sometimes. Unless you would rather use the cash raised for other purposes the better a lathe is equipped the more versatile it becomes. If you dispose of the equipment you regard as surplus then it will be near certain a job will come along that needs it. I have to fight my inner hoarder but I would keep it all.
