Not the Repair Shop, but Money for Nothing again. Today, a lovely old piece of mechanised gardening equipment that deserved to spend the rest of it's days in a quiet corner of a museum was heartlessly broken up to make two occasional tables from the wheels and guess what? a lamp from an internal cog with a candle bulb stuck in the top. Wonderful. I think it sold for some vast sum in a shabby-chic boutique. The Repair Shop is somewhat more acceptable. I do think there are some skilled people on there, particularly the clock restorer. I used to know a very skilled precision engineer who could fabricate all manner of tiny gears and parts in his workshop. Skills that are probably rapidly disappearing. As for criticism of the radio restorer? I don't know if I could appear on camera and make much sense either! And yes, I normally have better things to do than watch daytime TV, but sometimes I have to take the odd rest day off from work.
Alan.

I saw a couple of the episodes today. Hated the radio as there was so much wrong with what was said.

However I do have to defend the ladies that do the bears. They DO know what they are talking about. I met them in person a few weeks ago and they have a bear of mine for some restoration.

Before getting too precious about the items on "Money for Nothing" it's worth remembering they are going in the skip otherwise. We should be horrified by the things being thrown away and the fact that the general public is forbidden from saving and using any of it.

The worst crime on that programme is the quality of the "makers", a good example being the old lighting man who basically rubs a bit of wax over the item and then has someone else do the creative bit. At least on the "Repair Shop" they seem to know what they are doing.

The formulaic, repetetive structure of these programmes is infuriating but it seems to be the way of television these days, one of the reasons I watch very little of it.

Yes, that's fair comment - the end result with the huge bear was excellent.

I thought the clock restorer seemed competent too, not that I'm qualified to say, but he was a tad melodramatic. He said something along the lines of: "Ah, just as I thought, the pinion is completely shot - that could be catastrophic". No it couldn't - the clock would just stop working. A 'catastrophe' is when an avalanche wipes out a village or a plane crashes killing all on board - not when an old clock stops working and can be mended. To give him his due, he did use the proper term 'wheels' not 'cogs' or 'gears', which the uninitiated tend to use.

I suspect that much of what they say and how they say it is words put into their mouths by the producers. As the saying goes, 'When the dummy talks, watch the ventriloquists mouth'. It's clearly a series that appeals to many, and for those to whom it doesn't appeal, there's the 'off' switch. Arguably in a troubled world, there's much to be said for light-hearted programmes that don't take themselves too seriously.

Hi Jim.
The springs will be German, unless Smiths / Enfield British, and may be OK.
You'll need to clean all the old grease off - don't worry about them being straightened, apart from the inner coil or two.
Have a close look at the outer holes as it will those with splits if there are any.
Clock grease or car gear oil is fine - lubricate before fitting in barrel.
Strike and going train springs are usually the same, chime spring is larger.
Goggles needed!
If you need more in-depth advice, feel free to PM me.

Hi Jim. You have a PM.

The use of the term ‘catastrophic’ to describe a gear train failure in a clock mechanism is not over-dramatic because the extent of the catastrophe is usually limited to the clock itself. I’ve heard the word used in phrases like “catastrophic gearbox failure”, “catastrophic engine failure” and so on in aviation, shipping, railways etc., meaning an instance where extensive damage is caused to the mechanism concerned.

A fractured pivot in a clock can cause the geartrain to become unmeshed, allowing the spring to unwind at an uncontrolled rate, usually severely damaging other components in the process. There have been cases in tall tower clocks where a train fault allowed the weights to fall unrestrained to the ground, causing structural damage - I think this even happened to the Tower of Westminster clock once.

When I was about 9 or 10, I caused a catastrophic gear failure when I disconnected the "flying balls" speed regulator of what had been my late grand-dad's old wind up gramophone to see if it would go faster. The result was a puff of smoke and lots of small bits of flying brass as the steel worm gear destroyed the teeth of the matching brass pinion in about a second from the energy of a fully-wound spring!

I guess that a succession of such survivable accidents helped many of us learn our trade!

The clock in what is now the Elizabeth Tower certainly did suffer a catastrophic failure - one end of the mechanism essentially exploded when it ran away, causing major damage. This damage was repaired, but I believe the clock is currently undergoing a total restoration concurrent with major work on the tower.

Not bad considering that it was designed in the early 1800's by someone who had never done it before! The chime fly arbor split in 1976 when it was fully wound, so the 4 ton weight hurtled to the ground.

There's a good video here, before any current restoration started -

Wow. I think I'd be reading up on the 'Otis safety elevator' if I were involved in that!

I'm probably in the minority but I enjoy this program and the stories about the objects, clearly its staged and the restorers (experts may be able to criticise the restorers but most seem highly skilled to me) will be directed but it is an entertainment program not a technical instruction video.

Many of the items would probably end up in the bin so its great to see people fixing things on mainstream TV, hopefully it will encourage viewers to have a go.

Personally, I think it’s been acceptable so far, within the context of the thread title. It’s also nice to see that some vintage radio enthusiasts also enjoy horology. However we’d be wise to remember that the Forum is mainly concerned with vintage electronics and electrical matters.

I have of late been spending some time on the NAWCC Message Board, which is rather like this Forum but dedicated to clocks and watches. It is extremely good, well moderated and populated by some very helpful and generous people. There’s an American influence of course, but there are plenty of UK and international members on there. Other clock forums may be available but I doubt that they would be anywhere near as useful.

Indeed. This is probably why electrical items like clocks and radios are shown as being complex or dangerous, to discourage people from having a go with something that could put them at risk.

For inexperienced people, replacing a mains clock movement with a battery one is probably the easiest and safest approach. And for electronic items (whether battery or mains powered) showing fancy test gear and mentions of replacing parts for safety reason will probably make people think it isn't something they can tackle.

They do have just 50 minutes to cover three restorations along with the back-stories, and overall I think they do so in an accessible and entertaining way. Way better than most day-time TV. More knowledgeable will obviously spot inaccuracies in the information given and staged moments and reactions, but that will always be the case with this sort of show.

If it encourages some people to try to repair things or to look into getting them repaired rather than dumping them, while being entertaining, then I think it has succeeded.

Maybe the repairer was correct, the LW coil looks to be the wave wound coil on the righthand side in the early part of the program (I've not watched all of it yet), and appears to be connected to the correct switch contacts, maybe the ferrite rod assembly had been fitted the opposite way round (compared to the service info) at some point in the past?

The same radio repairer (Mark) will be featured again in a forthcoming episode later in the series.

I've now had a closer look, the coil he pointed out was the LW coil.

Close examination shows it to be wave wound as one would expect for a LW coil.

The video also shows that it's connected to the correct switch contacts on the wave change switch, the orientation of the whole assembly however is opposite to what's shown in the service info, but....later on in the program he swaps out the coils etc and fits them in the same orientation as what's shown in the service info, eg LW coil on the left and side.

Just finished watching today's episode which I really enjoyed, especially the restoration of the Penny Arcade machine having an interest in them myself over the years.

I will probably binge watch them all these episodes at some point if I get the time; it is certainly a baby-step in the right direction, and refreshingly free of drill bandits. It still has Jay Blades, but he's relatively harmless!
