|Thread: Weight and transportability of a Myford lathe|
Perhaps look at a graph of half life or capacitor discharge?
|Thread: Why does everyone disagree with you|
I don't get it right every time!!!
And finally anyone who hasn't exactly the same sense of humour as me should be taken out and shot now (That was another joke, by the way!)
|Thread: Leaf springs|
A couple of thoughts - firstly the spring material you have bought will, according to some supplier websites, need to be heat treated and secondly you can perhaps work out the loading on each of the six springs on a best guess principle for a maximum water coal and driver load plus sprung weight of the completed tender.
Alternately input Martin Evan's spring design into one of the leaf spring desing formulas on the internet. These springs are of a relatively simple desigh with only one full length top leaf and single leaves of the other lengths so you should be able to obtain an approximation of their deflection under load to compare yours with.
Unfortunately your proposed springs with multiple leaves of each length are a harder problem to calculate (at least to someone who last looked at spring design at Uni nearly fifty years ago and never since!) so doing the same for yours may not be an option.
|Thread: Opinion on using blue Loctite (thread locker) on clocks?|
Martin Evans (not the current editor of ME, the one before) came and gave a talk to the society I was a member of then and showed us a crankaxle for his Princess of Wales design built up and Loctited.
This generated a load of discussion and correspondence in the club newsletter with some saying 'Its not engineering, its a bodge' etc etc
This was 1971 ………………. !
|Thread: Leaf springs|
Conventionally, when making leaf springs to scale they are far too stiff, so the solutions are either to slot the leaves, replace some or all of them with Tufnol or similar or to replace each leaf with a number of thinner ones, so I suspect your springs, if each leaf is made up of a number of thinner ones will be softer not harder than as drawn.
As a 7 1/4" locomotive the driver sits on the tender so it has to be able to take a reasonable amount of weight (particularly in my own case!!)
The club Highlander is off the rails at present awaiting a new boiler and repairs, but I can have a look at/take photos of the tender next weekend if it helps.
|Thread: What a nightmare|
I asked a police civilian investigating officer about this a bit back and he said that while a clip from a dashcam can be useful in the case of an accident, the ease with which videos can be edited today makes any video evidence without a timecode track to show where it has been edited (or not) of little use if a case comes to court.
Thinking about it, I think it would be perfectly possible to superimpose a time of your choice on the footage and say it was recorded then for example.
|Thread: I wish mine was like that!|
I am quite the reverse - If I need it, it is not silly bad value and I can afford it, it gets bought - and after that the price is forgotten - especially in the case of things bought to do one job - any use after that is a bonus!
The only problem is when 'if I need it' morphs into 'I want it'
|Thread: Where Can I Get Machine Handles?|
Arc Euro do some, but just the same as those from wds above they are metric thread - look under machine spares
|Thread: A change of scale.|
What is the drawing of?
If it is a traction engine or an engineering model then 1" scale is used - but if it is a locomotive then 5" gauge is not always 1" to the foot - as Wikipedia says -
For standard gauge prototypes at 5 inch, the "official" scale is 11⁄16 inch per foot or approximately 1:11.3. Alternatively 1.1/8 inch per foot is adopted, allowing a scale of 3/32 inch per full size inch.
|Thread: Apologies for raising this again|
Attach the flywheel to a faceplate as you suggest but turn the teeth off with a trepanning cut so no intermittent cut. In effect you are cutting off what amounts to a thin 'ring gear'.

|Thread: Lathes as bling!|
My Francis Barnett hardly moved at all!
|Thread: Electric welder at Lidl|
Totally agree with the comment on gasless wire, but horses for courses - if you are lying on the drive trying to repair a rusty car the shield gas can disappear with the slightest breeze while a gasless weld, although far more grotty to look at, will have welded OK.
Its what angle grinders were invented for
The issue with cheap gasless welders is that they are often gasless because you don't pay for a regulator or a bottle of gas in the box and that all helps to make them that few quid cheaper.
|Thread: Lathes as bling!|
I agree - Slimbridge is not too far from here so I shall make a point of going there with my lathe hanging around my neck
|Thread: Online ME index|
Indexes for the magazines used to be available printed on paper for a nominal sum plus SAE from the publishers - references in the online ME index to indexes appear to be exclusively to announcements of their availability, not an index as an article in the magazine. The online index at **LINK** suggests that indexes exist for many years from volume 4 onwards.
Bound volumes usually, but not always have the printed indexes included - that is what they were produced for so the easiest way is to find a bound volume and look for the index in there. Some ME clubs have complete sets of bound volumes.
My local library used to be able to get loan volumes from the Library for Science and Technology at Boston Spa in the UK, but I don't know if this even exists anymore. A local university might be another option.
|Thread: Steam operated drain cocks|
Looking at the index to Model Engineer at **LINK**
There are two references to 'Steam Operated Draincocks' but that doesn't mean there are not others under references to particular model designs.

|Thread: why does my makita go pop occasionally ?|
Have you had the drill from new?? Although not the same brand, it was not uncommon to add the variable speed switch to B&D drills that were originally single or two speed - I have done several myself.

|Thread: Windows 7 support ends|
Buying porn????? - I have a hard enough job avoiding the stuff falling into my inbox as spam without going out and actually wanting to pay for it.
If you are a club secretary, treasurer or similar you may need to update to receive security updates to be seen to be ensuring data security under GDPR - but that is an entirely seperate minefield still!
I am not certain these are available for retail or OEM customers - only volume licencing or Cloud Solutions
|Thread: British Transport Canteens...|
At school 50+ years ago the school Railway Society (an amalgamation of the Locomotive Society and the Model Railway Club) used to meet Friday lunchtimes and several times a year we used to show British Transport Films - free to the school except for the return postage. All are now availble on dvd and many on Youtube or BFI as well.
We used to charge a nominal fee as far as I can remember, but as projectionist (they were all on 16mm) I got in free.
Favourites included 'Elizabethan Express', 'Giants of Steam', 'Snowdrift at Bleath Gill' and 'Lets go to Birmingham' and of course 'Night Mail' if the Benjamin Britten score is not too modern for you.
'A Letter for Wales' is only available on dvd but has some good shots of steam locos and a Hunslet quarry tank at work in its original setting.
An amazing film showing exactly what NOT to do to stay safe near the railway is 'The Finishing Line' Full version is 20min with lots of fake blood and gore!'
