|Thread: An electrostatic mystery ...|
Prompted by the various ideas above, with hardly any correlation to model engineering, I can offer no connection between static charges and travel sickness. Indeed, this 1st part of my contribution mentions nothing of the subject. Escape here
However, crossing the Bay of Biscay in a troopship (The Empire Ken) late February ’57, I was the only one of our group of eleven who had not ‘been to the side’.
Determined to test my endurance at the risk of being ‘clapped in irons’, and in near total darkness I stepped over the barrier marked ‘Out of Bounds’, and eased myself around to the very stern of the ship.
It was pitching to a level where (I suspect from the vibrations) the propeller was emerging from the ocean; perhaps pitching as much as 30 feet (say 10 metres). After five minutes or more, I was satisfied at my endurance, and concluded this rather foolish experiment.
Having thus confirmed my previous experiences (the IoM ferry from Fleetwood a couple of times, and a ‘pleasure’ cruise off the Scarborough Head, complete with a generous encouragement to be seasick), I was convinced that I was immune to travel sickness.
A few years later, I was obliged to ‘accept’ a car lift from my boss with the promise of a ‘chicken and chips’ supper, followed by homemade apple pie with cream, if I would navigate us across London.
That was when I discovered that I wasn’t immune to travel sickness. Head down to read the map in relative darkness was apparently the perfect combination. Fortunately, I didn’t disgrace myself, and have learned since from a friend who navigated during car rallies, that it was the heads down thing while being tossed around willy nilly.
So as not to jeopardise their chances of a good result he told me that, under those circumstances, he would hold open the car door and lean out to release his last meal.
We crossed London without incident, and I managed to enjoy the ‘chicken and chips’ supper, with homemade apple pie and cream, thus avoiding embarrassment.

Machine issues aside, it's great to see such clear photographs chaps.
OH for a workshop Gray!

Adrian, I sent you a PM.

You SOD, you have the negative back to front!!!

'Clogs were still readily available during my childhood in NW England for operatives in cotton mills'
... and kids like me in primary and the first few months of secondary school. I was banned from the slides on the frozen playground. The irons apparently tearing up the nice smooth surface the older kids had produced.
Clogs were lovely and warm, and could make sparks by kicking the concrete a glancing blow.
The co-op was always busy in the clog-repair shop.
Someone in the toolroom was not impressed when he caught me winding a 0-1 around by gripping the thimble in my fist - "... and stop swinging it around like a clog iron", he yelled.
Another pass-time, although I never saw one was 'clug feytin o'rt moss'.

In the 1891 Census, my paternal grandfather aged 15 was record as Blacksmith. They were tough in those days
Ten years later the 1901 Census shows him as Agricultural Engineer. When I checked for this jump in his status, it transpires he may well have remained as a Blacksmith. He died while my father was only six, so I didn't get a chance to ask.
Some of these are interesting ...

|Thread: What makes your bristle?|
It still happens down here Tim
A good one Rod. Not so brutal.
I noticed that I was holding my breath at several stages as his soldering iron touched where it shouldn't have.
With several thermoplastic mouldings, there was a potential for one or other to be polyacetal (POM).
The fumes from burning POM can lift your head off, so be careful chaps.
Back again Bill.
I thought you'd be interested in the (potential) consequences of water leaking into the inside of your cordless tooth brush.

|Thread: Railway sign|
Not a railway sign this time, but it made me smile.
Back in the 70’s, freeways were ‘coming into fashion’. One of the early ones to be constructed was a length of about eight km taking traffic out of the city. At the end furthest from the city was a ‘T’ intersection.
It caused the inevitable pileup.
Here, drivers of semi-trailers had to make tight left-hand turns to clear the corner building. On this corner had been a delicatessen, a fact only made clear following an over-tight left-hand turn. A large truck had torn away a small section of the shop awning.
Revealed behind the crumpled mess was some of an old sign.
It read "DELICATE____".
And, I didn't have a camera.

At an 'S' shaped level crossing down here, there was once a sign for motorists which read ...
SIGNAL BEFORE TURNING
Clive, I thought it said "Do not use toilet unless train is in motion!"
|Thread: 1959 Nsu quickly|
Apologies Dave, I can add nothing about NSU.
Chris’s mention of Cyclemaster however, brought back a flood of memories. I clocked up many miles on my 32cc version. The main setback was those messy coupling quadrants. Made from a certain grade of rubber, if oil got to them they turned into a squishy, sticky mess.
Just before I sold it in ’56 to make way for the (no longer avoidable) OHMS invitation, I fitted the bike with a ‘long-range’ BSA Winged Wheel pannier-style petrol tank. With a pocket full of rubber quadrants and two tanks, Lands End to John O'Groats was a distinct possibility.

|Thread: A Unique Word?|
George - Re Galahad ... I wouldn't know where to start (or finish), although I'm reminded of a sentence which starts with ...
I is ......
I is the ninth letter of the alphabet.
Was it this one George?
The publican of the Pig and Whistle ordered a replacement sign for his establishment. Upon viewing the new sign, he expressed dissatisfaction to the sign maker. He asserted that there was too much space between pig and and and and and whistle.
This might open another tin-of-worms.
Some may have heard/read the word 'and' written consecutively five times in the same sentence.

Where would I be without your help Michael?
I've removed my dark glasses, and can hear much better.
|Thread: Meshing with Lantern pinions - Part A|
Definitely a significant error of mine Michael.
Thanks for bringing it to my attention, and apologies to all.
Cycloidal NOT involute!
It's time this SOB packed his bags.

Here are the links ...
|Thread: Meshing with lantern pinions - Part B|
As a convenience, here is roughly where Thread Part A ended
To conclude, perhaps I should have carried the exercise to include deepening the meshing, i.e. crossing over the two PCD’s. However, I’m inclined to think that the results would be fairly obvious in that the teeth/leaves/pins would soon clash.
Unlike the previous exercise where contact of wheel teeth and pinion leaf flanks produced slight changes of contact traces (especially the ‘On centreline and 0.1mm offset), the round pins of the lantern produced smooth curves. Similarly, as here …
… the cross-overs of the pressure angles are less severe.
Finally, and despite my own luck, only slight changes in depth from the theoretical (i.e. less than 1.0mm) suggest that depthing, at these sizes in particular, needs to proceed with extra care. No doubt for those with depthing experience, you will recognise how the meshing behaves. Too deep and there will be a gnashing of teeth? Too shallow, more gnashing?
Links to both albums are here …

Meshing with Lantern pinions
Thanks for everyone who helped.
Apologies if this mesh came unstuck.
