Thread: Clubs during crisis
19/05/2020 13:56:13

Thanks for the link. It didn't come up when I did a search initially. My post can now be cancelled rather than duplicate.

Good morning all.

Just a quick survey of members of Model Engineering clubs (or any club) with regard to the crisis 'lockdown'.

Has your club locked up and virtually disappeared, or have they come up with any creative ideas to keep in touch or use some of the out side facilities, keeping withing the social distance rules of course? I'm thinking mainly of track use, but it could be anything.

Social contact is vital for any prolonged period and clubs can play a vital role in this. Maybe your club has come up with something special, if so, please share it on here.

Thank you

Thread: Pre-load of new bearings

Real feeling of nostalgia here reading this post. Sadly Timken (British Timken) no longer exists as they transferred operations from the UK to India and the two factories I spent my apprenticeship at are now housing estates!

I spent a while as a technical rep for the company before moving on to new pastures and I would advise anyone who has doubts about fitting bearings on a machine tool to ask the bearing company for advice. No point in trying to re-invent the wheel as it's old technology and all the info is readily available.

I have a good collection of bearing catalogues accumulated over the years. Initially, trading in bearings was our main business. Here is a photo of a small section of the book shelf just above where I sit in the office:

timken.jpg

It represents a snap-shot of how Timken went through transformation of ownership over time .... TIMKEN.. followed by being part of Torrington, .. followed by separation into Koyo - JTEKT taking over Torrington... and so on. These buy-out and changes have always been there, and very common in the bearing industry.

I was once told by the Torrington rep., that the likes of TIMKEN/Torrington were mainly here/ there to primarily serve the automotive production industry. When I entered the bearing sales industry back in the late 1980s, Mr. Timken was busy trying to shut down Chinese factories which were making equivalent type of bearings. Ten odd years later, Timkens own production to serve Asian markets is based there, along with other locations throughout Asia. By the time we stopped getting direct supply from TIMKEN when it was part of Torrington in mid 2000s, the European market for Tapper Roller Bearings was served by their production facilities in Turkey. By this time, it was difficult to consider/justify paying the prices they wanted for the brand for 'standard' TRB sizes, when we could get Japanese equivalents in NACHI and KOYO - without compromise on quality - for nearly half the cost which TIMKEN - made in Turkey wanted.

From what I can see from this link, currently TIMKEN still remains an AMERICAN brand, with FAFNIR being part of it. Operations - as in decision making - still remain firmly in Ohio USA, with Madras - Chennai link just being another part of their global empire to serve their customer base, wherever they may be.

Thanks for the update since the '80's. I lost track of the company, and a few colleagues when they shut down in England. I know a fellow apprentice who ended up being the works engineer and went to India to set up the factory there, and then was no longer needed!

When I started in the '60's, production at Northampton was mainly for automotive and machine tools. Business boomed when the Vietnam war was on, a whole production facility for fighting vehicles, and we had many car plants around the country then.  Larger bearings and railway axle boxes were produced at the Daventry factory. Large bearings used on radar installations and larger machine tools, even the BT tower in London. As a rep, I visited many customers making cars; trucks; planes; machine tools and ships, in fact anything that required bearings. What industry we had then!

It was a great place to work, they relocated from Birmingham during the war into a brand new factory which at the time was the largest factory in Europe. The only reminders now are a couple of road names on the new housing estates.....how times change!

I did get the impression that the police do not like trying to enforce the 2m separation rule.

JA

Yes that's quite true. In the main, the Police have to deal with the scum of society and a lot of the rebels of social distancing fall into this category I'm afraid. Experienced Police officers will think more than twice before taking action. They, like those poor health workers have unsuitable protection (if any), so why would they risk getting infected and taking it back to their family.

Thread: taper roller headstock adjustment
09/05/2020 10:01:49

If you've eliminated all the possible causes mentioned by other's and still have the problem, it could well be the bearings after this time in service. High speed use and then a long 'lay up' would have a detrimental effect on the bearings.

Taper roller bearings are very easy to maintain. I would suggest you ascertain that the cones aren't 'stuck' on the shaft. If they are free you can adjust the preload to the recommended amount by the manufacturer. The bearing set must be preloaded. When adjusting, always keep the bearing moving. Forwards and backwards by hand will do. This ensures the roller moves to the correct position and seats on the thrust end of the cone.

If you have any doubt about the condition and you want to keep the machine it often pays to replace with good quality bearings such as Timken. They are not cheap though!

It probably doesn't apply in this case as your's is oil lubricated, but where the bearings are lubricated with grease, do not over fill. A common cause of failure is too much grease, it heats up and will wreck a bearing very quickly.

I hope you get get it sorted soon, it's very satisfying solving problems like this.

Thread: Aircraft General Discussion

Chinese 777 cargo flew into Stansted from China this morning. The heavies still arrive as normal, but it's a bit worrying that Wizz Air are starting passenger flights from Luton with Spain and Portugal on their destination list.

I did ask RVL about their survey flights and they said they were classified, but they did say they're taking advantage of the clear skies. The drone out of Lydd is busy as well.

13/04/2020 10:39:56

With clear skies, the sound of a 747 Cargo throttling back getting established onto the ILS to Stansted yesterday, made me go outside to look at it. Very reminiscent of the days when aircraft were a rare sight! Inbound from Moscow, so cargo would be? Very interesting.

Still amazed by the amount of passenger flights into our country.....utter madness!

Unfortunately this country has avoided actual lock down. It would have made more sense to close everything other than hospitals and really essential services and we could have got over this a lot quicker, as S Korea did for example. Today airports are still open and the possibility of the virus coming in from Europe; USA and the rest of the world is highly probable. No arrivals are being checked, they are let loose into the community while we are all staying in obeying the rules!

Sheer madness in my opinion. An RAF A330 left Brize Norton yesterday and routed to Goa, presumably to repatriate people. This should not happen, unless these people have been tested accurately for now being immune (highly unlikely) they should all stay where they are.

Passport renewals are not an urgency!

The plan was never to have total loss of tranmission / lockdown. The idea is to slow the infection rate so the NHS can cope. Same number of cases but spread over longer period. You have to have some transmission for this to work. If you had totl lockdown you would have zero new infections and then when you let pople out the number of cases would be just as bad as if you had done nothing and he NHS would still be overwhelmed.

Edited By Robert Atkinson 2 on 09/04/2020 12:51:47

I'm sorry, but I don't think we had a plan! Enabling the NHS to cope is obviously necessary, but why were they so unprepared? The lack of basics such as PPE is unacceptable. When China released footage to the world of the desperate building of those hospitals in January, the rest of the world should have realised that this was serious.

As I said before, to keep reinfecting doesn't help at all. South Korea got back to normal very quickly, and now flights are again being allowed, they will have to be careful, to my knowledge they are testing at airports but my contact there hasn't reported lately.

Had the world sat up and taken measures at roughly the same time, we would all get over this a lot quicker. As it is, we will more than likely be staying in until the last country catches up. Try telling those who've lost loved ones that 'herd immunity' is a good thing!

This thread has now reached 34 pages and there are many comments ranging from real health problems to worries about deliveries. This forum has members spread around the world and this problem is global.

We have known about this virus since December last year (first case in China in November), and we saw impressive footage of the Chinese building two hospitals in January within two weeks. That worried me then, as China wouldn't have gone to those lengths if it wasn't serious, but I was told by friends and family not to be so alarmist, it's just media hype etc etc. Why didn't so many countries around the world sit up and take notice?

We are suffering now in the UK because of lack of action and correct strategy by our government who to date have shown they are incapable of actually governing. We were under resourced right from the start and they are now trying to play catch up. We were just advised to keep on washing hands whilst singing happy Birthday. Stay indoors unless absolutely necessary, which in the main we are all complying with. However, as I write this an Alitalia flight is in the air routing from Rome to Heathrow. Three flights from JFK will take off today routing to Heathrow. These are just two examples, NO checks or quarantine for passengers when they arrive! ALL airports should be closed except for urgent cargo.

My question for our so-called government is Why? When we are doing our bit by self isolating and fearful of going out to buy food, are you still allowing infection into the country on a daily basis? I do understand it's tough for those who went on holiday during the this time and find themselves stranded, but most were aware of the risk before they went. They should be quarantined where they are until fit to come back. This is a global problem and should be treated as such. Maybe it's time for the UN to get involved?

South Korea for instance stopped all travel and tested their population right from the start and they are now recovering. Tough measures bringing faster results. Simple!

I hope you all manage to stay safe, wherever you are. For those living alone it's essential to try and keep positive as this could drag on for longer than we realise. Unfortunately no one knows and that fuels anxiety.

RMA - what you are seeing on Flight Raidar are pax aircraft flying freight with empty cabins or occasionally packaged freight on seats.. You won't make profits on this sort of operation but it may cover costs. Most 'passenger flights' earn sizeable revenues with the holds carrying up to 20 tonnes of freight.

rgds

Bill

Not exactly true. There are many freight only aircraft in the air at the moment, and I've had details from Delta, United and Lufthansa who are filling the seats with packages as well as the cargo hold of the plane, probably worth the risk if they're carrying essential medical freight. That leaves many passenger flights still going on, some of which are rescue flights of course.

The point is that any aircraft flying from one continent, state or country to another whether freight or passenger will spread this virus. In the meantime many countries are in serious lock down and some not. Unfortunately we are not yet in the lock down position. If the world wants to recover from this we must collectively stop travelling. I've just checked North America again and it's covered with aircraft in flight....certainly not all freight!

29/03/2020 14:05:59

I don't know where you live, but I have two members of my family who are Police officers and they are too busy with other things including dealing with morons who keep calling them on 999 for the most stupid things! They're not stopping people here! Not many people about anyway as most are being sensible.

True, many aircraft are freighters, but have a look on Flight Radar and see how many passenger aircraft are in the air at the moment. Last night North America looked perfectly normal!

In my opinion we have a global problem and it should be a global lock down....too many weak links, and no health service can cope with it.

Only if you're prepared for a £30 fine and a criminal record. Going for a spin on your bike is not 'essential'

Duncan, I think Hopper is in Australia and not sure if tthe police are issuing fines.

Mea Culpa

but they are stopping people in the UK

I don't know of anyone actually being stopped by the Police in the UK. We simply don't have enough officers to be effective in this. The media keep on saying the UK is in 'lock down', it isn't. Boris has only issued advice, nothing mandatory other than closing selective businesses and gatherings.

I can't get to Spain for obvious reasons, but I'm in touch with my Spanish neighbours and read the Spanish press daily. That country is in real lock down, and the Police are patrolling everywhere, even the supermarkets. Spain has a massive Police force so enforcement is being carried out. One couple in Madrid have been fined 60000€ each for going to the supermarket!

Having said that, Spain has suffered badly and it's not yet contained in spite of serious lock down. A couple of reports I've read indicate that bulk purchase of useless testing kits, and football fans returning to Spain after a major football match in Italy.

As many have said on here, going out for food is the weakest link. We stay indoors for a week and then go to the supermarket, all the good work possibly undone, but there is no alternative.

I think mental health issues of many who live alone will become the major outcome of all of this. Maybe the government could start preparing for that, it would be good to be ahead of the game for once. Media headlines this morning speculating that it could go on beyond June is no help to anyone, it just fuels anxiety.

Hat's off to all the public servants....NHS, Police and Fire service, all on greatly reduced budgets, and the many who are doing a fantastic job who I haven't mentioned.

Is the world taking this seriously? I've just looked at Flight Radar and it's surprising how full the skies are with aircraft! I personally think world economy is getting more consideration than world health!

I hope you all manage to stay safe. Now off to the supermarket for my weekly essentials!

Thread: Basic battery charger
10/02/2020 08:34:54

Mine is a lot older than yours and they are notorious for electrical problems such as windows losing memory or the top sluggish in operation, even when the battery is a little below par, so it's a good idea to keep an intelligent charger to hand. I even have a spare battery which I keep charged just in case, although they are very large and heavy and awkward to swap over in the boot! If the car is a daily runner, there shouldn't be a problem, but I do less than 2k miles per annum in it so the charger in invaluable.

The completely dead battery was on my digger and this did get left for long periods. These chargers worked wonders on that battery!

Posted by Simon Barr on 09/02/2020 12:30:04:

As far as intelligent chargers go I can recommend Ctek ones. I've had one for around seven years now and it is fantastic, not cheap but fantastic. It's been used on all sizes of batteries and even has an AGM setting. In my experience 'old fashioned' chargers are just as likely to knacker a battery as charge it, they all overcharge to some degree. You can just leave an intelligent one to analyse and charge appropriately.

Well worth what it cost me.

Some members of the Jag club have Ctek and swear by them. I have a couple of intelligent chargers from Lidl at £13.99 each and they are great. I'm no electrical expert, but apparently they pulse a dead battery back to life; charge it and then discharge and trickle charge alternately if left connected. I keep one on my Jaguar all the time when laid up for any length of time, as these cars will soon drain a battery when idle for a time.
