    Does anyone remember Miss Marilyn's Super Flying Fun Show, a channel 9  kids morning show  from the early 1970's? It had Rod Hull who played some bloke called Caretaker Clot, from memory.  Maybe it was a Sydney only show.....

     

    Yes, and all in black and white.

    I watched it in Melbourne and I was always up early for the start.

    The programme before it was always two "old blokes" talking the most boring stuff imaginable to a kid - probably politics.

     

    "Watch out, watch out - there's a Humphry about!

  2. I thought the "country code" encourages you to "leave gates how you find them".

    (...with a very few exceptions of where the gate is obviously in the wrong position.)

    I don't know much about it, but 100% it's nothing to do with AC electrics as the trains run off 1500 volts DC.

     

    Not AC "Traction" power/supply, or transmission, but simple interference rejection of the domestic 50Hz supplies when operating "sensors" remotely from the signalling system/network.

     

    I also wonder if it might just be a simple "spark gap" used to protect the occupancy circuits if AC traction supplies are present and fault to the rails.

     

     

    Kev.

     

     

  4. Is it a "load" so that the occupancy detector can detect that the circuit is working even if a train is no "shorting" the rails together?

    Think of it as a resister and that the occupancy detector can detect 1/ an "open circuit" - a fault, 2/ an "unoccupied circuit" - line clear, and 3/ a "short circuit" - a train or line occupied.

     

    Of course, it makes more sense if it is actually a capacitor (providing impedance) so that it works with AC electric - of a frequency that does not correspond with "mains" frequencies (and their derivatives).

     

    Just my speculation as I don't work in the rail industry.

    This could be an advantage if you can't find the receipt.  😉

     

    Or you can buy and pay on line and have full proof of purchase with details.

     

    I've found that not all things are available online forever.

    Can you still get a "Hattons" receipt online?

    Sadly in my experience most smaller model shops only give extremely basic receipts that have the amount of money spent listed but no details of any use on what the money was spent on.

     

    I was thinking that too, plus the fact that some receipt materials used just fade away - usually years before I even start the project that the receipt paid for!

  7. The "resultant finish", of fake products, "may not be the same" because any defects/loss of fidelity does not matter to them as they fully intend not to support them in any way once sold - unlike a legit business which must factor in these costs.

    How do you know that Dapol can't tell the difference between of their products and a 'fake' one?

     

    They can. It's called "proof of purchase".

    This thread really does show why "proof of purchase" (a receipt) is so important now - and increasingly so in the future.

     

    All sympathies, and support, to Dapol and other victims of this type of crime.

    How to uglify a nice looking aircraft, I'm sure these things are extremely impressive technically but they are not especially nice looking.

     I came across this on Youtube , not a ship but a different take on propulsion .

     

    I will post as a link as a tease .

     

     https://www.youtube.com/watch?v=oLRNf8nzcC8

     

     

    I loved the relaxed lifestyle there. Very tempting!

     

    ...but the "boating" was brill too. So effortless.

    I loved the super long Dip Stick, the bottle on the exhaust, and the efficient way they "seesawed" the motor bike off at the other end.

    The safety looked well catered for - at least there were life-jackets a plenty!

    The engine looked well maintained and tended. Clearing the Prop would be a doddle!

     

    Did you see how many "views" that video has!!

     

    Thanks Mike for posting that. Very therapeutic.

     Oh Dave , I think once again you have missed the joke due to the way some words are used

    over here , the pun is that 'won kee' can be used in  the form 'wonky' , an expression meaning

    out of line , not straight , at an angle . So the comment , not on the level is the joke , not that the

    place doesn't exist . 

     

    Very well said, sir, very well said.

     

    I was thinking along the same lines but resisted to respond due to my two over sized thumbs not being able to convey the clarity and succinctness required.

     

     

    Kev.

    (I too struggle with a few of the "double" meaning jokes on here.)

  12. When the motors were removed did you try pushing the locos around to gauge (sorry) the rolling resistive forces opposing your hands pressure - especially at starting/stopping?

     

    On the steam locos, did you rotate the gearing to see if there were any 'tight' spots anywhere when the main drivers had completed a full 360 degrees of rotation?

     

    Do these (older) locos have a flywheel? Replacing the old (heavy) motor, with a coreless one, will reduce the rotational inertia - which is not a good thing.

     

    I still think there could be too much grease, and as you are 'ok' at replacing motors - have you tried removing all the wheels from the chassis - thus allowing inspection/cleaning of the bearings/journals? (I realise that the coupling rods are an added obstacle/complication to doing this.)

     

     

    Kev.

  13. I really suspect that the 4F's running properties are nothing to do with the absolutely tiny value of the suppression capacitor. (It sounds more like "stiction" or too much grease.)

     

    If the PWM controller has feedback, then there is a small possibility that this could interfere but normally not.

     

    You can, of course, just remove the suppression capacitor, (they are hardly relevant today), and re-check the 4F's performance again.

  14. When I go out for a walk with my son, on the way back at roughly the right place, I says to him...

     

    "Don't worry, we'll soon be home. Just another million millimetres to go!"

  15. Lots of memories for me in that clip...

     

    I sailed on her sister ship - the SS America, but by the time I was on her it was renamed the SS Australis.

     

    It's such a shame but I think the scrapping of it is inevitable.
