This chapter was re-published over quite a period of time and clearly documents the amazing progress in domestic AV/computer/camera technology and online video hosting:
I found the You Tube video poor due to the heavy compression at this time. The size of the Google Video screen is much larger: It can even be adjusted to full screen with a click on the box at the bottom of the video screen. Unfortunately, due to the compression applied the Google Video still does not appear remotely as sharp as the original as I see it on my own monitor. Downloading the video is possible and may improve the video experience when played from your own hard drive.
A heavy video tripod with pan and tilt head is also necessary for the camera to remain steady. The welded steel stand for the WT must have a very firm base or the WT rocks like mad when running. All unnecessary movement not only looks very silly but detracts from the sharpness of the video for technical reasons. (blurring around the edges of moving objects) The camera *and* the WT movement must both be absolutely level. The WT must be framed without other distracting objects in the background. The 20 Volts DC power supply is necessary for the drive electromagnets on the end of a very long extension lead. A 9 volt battery must be applied at reasonably precise intervals to trigger the relay electromagnet to release the waiting train action. With nothing to resist the WT's driving power everything moves far too freely. The hand setting crank has a nasty habit of flopping down an extra tooth at precisely the wrong moment right in the middle of a"take!"
Last but not least: One must remain absolutely quiet during filming. There must be no wind (at all) or the camera's built in microphone picks it up and reproduces a loud roar! Avoiding heavy breathing, sighs of frustration, crunching the gravel underfoot when starting the camera, triggering the WT's relay and switching the camera on and off without a cable release is an absolute nightmare! Neighbours, dogs, birds and farmers never seem to rest either.
Only when the video is captured can it be checked indoors on the computer screen. Even when a half-decent video has been captured it has to be trimmed carefully with computer software. Then successfully stored and uploaded to the online host. Even adding on-screen text is not easy when occasional dyslexia rears its ugly head. e.g. Canon has only one "n" in the middle? Since when? It's not easy being a one man band at the cutting edge of video blogging. ;-)'

The WT shown is later in date than my own having plating on the brass parts instead of clear lacquer. It also has the later cloth-wrapped and resin coated electromagnets. No doubt these details were introduced by Gents to obtain greater cosmetic longevity and improve resistance to damp. There may also have been an attempt to update the appearance as time passed to match customer's expectations. However beautiful, lacquered brass may have been seen as rather old fashioned in the industrial context of most timekeeping installations.
Very few WT's would ever have been seen by the owner or the general public. The WT was simply a reliable mechanism for driving public clock hands. Not the work of horological art which modern collectors admire for its grace and form. Later WT movements were painted pale grey to match the racks and cabinets housing industrial electrical installations and telephony. Which is even further from the delightful greeny-blue paint seen here. Or the much earlier black paint and deep lacquered brass.
Here's my latest attempt to capture my WT with my digital still camera posted on YouTube.
I recommend the "high quality" viewing option for a much crisper picture and one which even stands "full screen" viewing. YouTube used to be much fuzzier than Google Video but has greatly improved its video quality lately:

Here my distant Gent's Pulsynetic master clock is connected to reset the Waiting Train mechanism. My past attempts to film the WT involved a 9 Volt battery to reset the WT and required rather more hands than most of us are normally supplied with. For this "hand-held" video I used my heavy video tripod as a "steadycam" stabiliser having become bored with the rather static view from a fixed tripod. The mass of the video tripod certainly stabilised the camera but it was so heavy I was struggling to support it with both hands! I hung an old sheet behind the WT to hide the untidy background mess of my workshop.
