As an aside to my comments above I feel that in some way I am doing my best at present to reduce my contribution to climate change because I currently have 4Kw of solar generation and 12Kwh of battery storage, on sunny days in the summer, not very frequent at the moment, I am able to be self sufficent and not draw any power from the grid, this only happens on selected days during June, July and August when the sun is strong enough, makes me feel good though.

In respect of my comments about the world population I was only stating facts and in no way do I advocate any methods of population reduction, the world population is what it is and nothing can change that. Dave W

The Politicians headlong rush into legislating for electric vehicles and the banning of the sales of new petrol and diesel engined vehicles is beginning to come back and bite them. Analysis of the carbon footprint of the production and use of electric vehicles has shown that they are in fact overall more polluting and damaging to climate change than the conventional petrol engined vehicles that they will replace. This has been established by more than one independent source, so far from slowing climate change then ev’s may well accelerate it. The goal of being Carbon Neutral is a hoax, I doubt that any country will be able to demonstrate that they achieve it without seriously fraudulent statistics being created. Any of Mankind’s activities will have an impact on the growth of climate change, the main problem creating climate change is the rate of population growth, the only way of effectively reducing climate change is to reduce the 9 Billion population on earth to a reasonable 4 or 5 Billion, I don’t see that happening anytime soon. The only reason we have an ever expanding problem of climate change is down to the population growth and each additional human will contribute to an ever increasing global temperature. Do we realistically believe that if we constrain our countries activities to reduce climate change all the third world countries will voluntarily conform to reduce climate change, I don’t think so. I realise my posting may seem doom laden but I am being realistic and coming to my conclusion based on the 76 years of experience that I have gained throughout my life, I fear for the way things will be at 2050 and beyond, it’s not the world I desire for my descendants to live in.

One wonders how much of the belt has shed in the way of particles into the oil system as your photos show the belt beginning to deteriorate. Dave W

Granddaughter has a BMW cabriolet, not a very sensible choice in my opinion as it’s ten years old but assured as one lady owner previously, believe that if you will, car broke down and eventually refused to move. Various helpful friends diagnosed that it was ignition coils as the problem. Granddaughter enquired of local BMW agents what were their labour costs, was quoted that they were charging £220.00 per hour, after much deliberation she took it to a well respected local garage that specialised in automatic transmissions as well as other strings to their bow. Their diagnosis, that was correct, was a duff fuel injector cost £350.00 for the part and they also fixed an ABS problem that showed up during their checks, bill came to £600.00 dread to think what the BMW garage would have charged.

I have both types of tool but must admit not had much success with the insert type, probably because you need to run at speed to be successful and having had some fearful lockups when using speed I am afraid to use its full potential. I now use the HSS blade type and find it very successful, you do need to make sure that there is the minimum amount of slack in your setup, not always easy on model makers lathes but from your posts it appears that you have probably got a commercial lathe.

Are these the same NASA controllers who direct manned space flights. 🤔. Dave W

Had the same problem with my Champion mill last week, motor would only run with the green button on the NVR held in. Changed the NVR but the same problem, eventually found that the problem was with chuck guard micro switch. Dave W

Probably not. Dave W

Problem now solved, I referenced a previous posting from 2020 which had the same problem on a lathe and was brought about with a microswitch on the chuck guard not making correctly, I traced my problem also to the chuck guard, now that I am aware I will take precautions not to get caught out again.

I am having a problem in diagnosing a fault with Champion V20 Mill, was milling a component, finished the operation and set up for next operation when I switched on the motor it would run, but only if I kept the NVR switch manually depressed. The NVR switch was not latching in the run position, I thought the diagnosis was simply a faulty NVR switch, I obtained the correct replacement from Chester and fitted it but still the same fault. I checked inside the electrics box for any loose wires but everything was sound, looked for any obvious blown components on the motor control board but there was no sign of any problems, checked the wiring inside the motor shroud and everything was fine, as a last resort I took the earth point apart and thoroughly cleaned it and reassembled but the same fault persisted. The motor runs fine and the speed can be wound up and down as long as the green button is held in on the NVR switch. It seems to be a latching problem in the NVR.

I am beginning to suspect that maybe there is a fault on the motor control board, the one fitted to my machine is a BC 2000-TB DC Motor Controller, perhaps there should be feed back from the board which controls the latching of the NVR, I don’t know enough about the electronics concerned.

Has anyone else had the same problem with their machines, if so what fixed the problem. I am coming round to the fact that I may have to replace the motor controller board but preliminary searches on the internet show prices starting at about £80 upwards if delivered from China and at least a three week lead time. I would need to be certain that it would cure the problem otherwise I would be taking a lot of flack from the Financial Controller, the price , within reason isn’t a problem as far as I am concerned, I have had a lot of service out of the mill and this is the first problem in eleven years.

Heres hoping someone can put their finger on what my problem is. Dave W

I had digestive problems for many years and it was suspected that I was gluten intolerant so proper bread was out of bounds, I found that baking our own bread using Spelt flour seemed the answer. Spelt flour is from an ancient wheat that was brought here I believe by the Romans, most people with gluten intolerance can tolerate it well, it is different from normal bread flour which comes from what is generically known as Canadian wheat which was genetically selected at the time of World War Two because it gives much enhanced yields and helped feed more people when supplies were scarce. It has continued in use because of its greater yield it is far more profitable to grow, its genetic make up makes it unsuited to those with gluten problems. The Spelt bread that I used to bake was virtually indistinguishable from shop bought bread, it’s taste was no different nor its texture when compared with shop bread, I must comment that the gluten free breads available commercially taste disgusting. My digestive problem turned out to be not the gluten content of bread but the yeast it contained, I get allergic reactions from both yeast and yeast extract contained in food products. Unfortunately yeast extract is used widely in processed foods as a flavour enhancer to disguise the poor quality of ingredients used like cheap meats etc. Now having all but excluded any yeasts in my diet, and yes that means beer and wine both made using yeast, I can sometimes tolerate some sourdough breads because they use a different strain of yeast and are prepared differently than ordinary bread, one consequence of excluding yeast from my diet is that very bad excema that I suffered on my hands has completely disappeared, my dermatologist said that there was a common link between the two.

Not had a great deal of success with using conkers to discourage spiders, in my workshop I put little piles of conkers in the areas that the spiders were frequenting, they used the conkers on which to build their webs. Dave W

Anyone who has served in the desert will know what I mean by camel spiders, fairly big, ugly looking and able to bite, though not venomous their bites invariably turned septic. I hate spiders and snakes, though I tolerate spiders in my workshop as long as they are out of sight. Dave W

The oil sampling of aircraft engines was carried out to determine when the bearings were beginning to wear, it was possible to detect microscopic particles that were shed from the bearings, We used to carry out the process on our elderly fleet of RAF Brittanias during the 60’s and 70’s right up until they left service in 75. Dave W

Definitely do not wear rings, not connected with turning or drilling but a colleague of mine when descending from a safety raiser, when working on aircraft, lost his footing on the greasy rungs of the ladder and a ring he was wearing caught as he was falling and rolled the skin and flesh of his ring finger right down to the bone the full length of his finger, fortunately he didn’t severe the tendons, but they were well and truly exposed. Once you have witnessed a nasty injury like that it focuses the mind and you make sure you take the necessary precautions. Dave W

Experimenting with grinding wheels when you don’t understand what you’re doing can have fatal consequences, there have been fatal injuries when a wheel rotating at speed lets go, is your life not worth the extra expense of a quality, safe , piece of equipment. Dave W

One of their own employees expressed his concern at the lack of Non Destructive Testing of the pressure vessel but was dismissed from his employment, they had the necessary foresight within their organisation but chose to ignore it with the resulting catastrophe, you can take a horse to water but you can’t make it drink.

I remember that when I was in the Forces, rooms were predominantly painted Eau de Nil as it was psychologically supposed to be the most relaxing colour. Can’t stand that colour now. Dave W

This is a clock related issue, in the 60’s my wife was given a wedding present by the girls she worked with, it was a handsome looking mantelpiece clock with a lovely highly polished wood case. Said clock performed brilliantly for a good number of years, it was an excellent time keeper, suddenly one day stopped working so I dismantled it to find the problem. Inside the case where one of the driving wheels should have been was a neat pile of black dust. It appeared that the manufacturer had used what was then a revolutionary material in its construction, carbon fibre. Apparently when first used carbon fibre had a tendency to a short life before the structure would disintegrate, something only found out when early components manufactured from it failed in service. Has always made me sceptical about aircraft components made from carbon fibre and enough said about deep sea submersibles. Dave W

A couple of years ago I stumbled on a list of NHS Hearing Aids on the net and the price that industry charged the NHS, the list was endless, I was surprised to find it in the public domain but apparently it was part of an open policy to ensure fairness in dealings with industry. I cannot remember how to get to it now but I do remember that most prices were in fact below £100 the most expensive then was about £120, the same aids were being retailed for £1,000 plus. I understand that there are those who would choose to knock the NHS but the identical aids are being provided through the NHS, the low prices they are supplied under comes about because the NHS buys large volumes through contracts with the suppliers in industry.
