|Thread: Pittler lathes information needed|
email firstname.lastname@example.org, if he doesn't have one in his collection, he will know someone who has!
http://www.lathes.co.uk/pittler/index.html is a good start.
|Thread: Microns ...|
So, how many angels will actually fit on the head of a pin.........................
|Thread: What method do you use to find center height for your lathe bit?|
I eyeball it to a centre in the tailstock, but I also use the 6" rulle method. First job you do turning is to face off, so you will know if you got it right or not, or you could face off a bit of scrap bar...............but what counts as scrap in the home workshop? surely it's all metal you haven't decided a use for yet?
|Thread: Metal de-coroder|
I use home brewed cider vinegar, and it is VERY effective, and free, and doent seem to attack the base metal. I have managed to save things that I had really written off due to rust, like some old thread guages, which are now like new, apart from some pitting where the rust had gone deep, but prefectly readable engraving on them, which was invisible before. Electrolysis in a bath of washing soda is also good, but gives off hydrogen, so beware of flammability. Some people also use white vinegar, or vinegar and salt.
|Thread: Hello from East Yorkshire|
Hi and Welcome Mark, whereabouts in East Yorks are you? I am in Driffield.
|Thread: water supply|
There is a large undergorund beehive cistern under my workshop, a left over from the previous victorian (or earlier) buildings. It is fed from the roof gutters ,it is BIG and thanks to our new wetter climate, stays full constantly. I have a pumped pressure system that flushes both toilets, and supplys water for handwashing to one instantaneous and one storage water heater. I also have a raw water tap for pressure washing. The only water charges I pay is the one to put your surface water into the sewer. I pay no sewage charge whatsoever, as sewage charge is based on a percentage of the water that goes through my meter, and as that water does not feed the toilets cisterns, they cannot make a sewage charge. I negotiated this deal with Yorkshire water, it was not a problem although they tried to make me pay a sewage charge untill they realised that I Knew they couldnt! You own the water that falls on your property and every Sq ft of roof provides .6 of a gallon per inch of rainfall!
|Thread: Should I have 3 phase supplied to my house?|
Three phase is very convenient, and there are power loss drawbacks with inverters, and it means that your three phase machinery is no longer plug and play, but I think £3100+ vat is very toppy when you have done the trenching on your property, and all they have to do is a joint and cable, and then fit meters. It would be a day job for two men, possibly three, but there is usually a fee to pay for opening a pavement too. In the days of the nationalised electricity boards, they had an incentive, as you would use more power when it was made available, but now the utilitys are seperate, and the cable installs are done by a differnt company to the one selling the power, the incentive is gone. Some thing did work better as nationalised industries!
|Thread: Aluminium cylinder blocks|
I am not a steamie or a Smee, but what about aluminium bronze, good wear and corrosion resistance, light, and although expensive, you could make your own aluminium/copper alloy.
|Thread: Oh bugger, I told you I was ill|
Lie still and think of Wentworth!!
|Thread: Electricity Supply|
This is totally wrong, we hit peak demand in the late sixties/early seventirs at about 68gW, today, after de industrialisation and massive drives toward energy efficiency, peak demand is around 45gW. Demand has fallen 15% in the last decade, and is continuing to fall as street,commercial and domestic lighting is converted to LED.
Robert Atkinson 2,
"There is also the question of where the electricity will come from. We need more (next generation) nuclear power".
Unfortunately even next generation nuclear power (should it ever be built) will not provide any extra capacity. It is only being built to replace existing nuclear stations that are long past their sell by date, and will be shut down if the new stations are ever completed. The remarkable reluctance to get on with new nuclear is due to the companies who are supposed to be building them getting cold feet about the possibility of them ever getting their money back, even at the (double todays) tariffs they have been told they will be paid for the power they produce. Add to this that nuclear stations use steam turbines, which are at best 33% efficient, whereas combined cycle gas turbines, which produce the huge bulk of todays electricity, are approaching 50% efficient. The comments about the infrastructure not being able to stand the extra load are quite relevant, but there will be very little extra load, as most people will not be able to afford solely battery powered cars, and there is little chance of a second hand market developing due to the poor battery life.
The recent "first two weeks without coal generation" is a bit hollow when you look at the tiny percentage that coal provides even when it is used! https://www.gridwatch.templar.co.uk/ As I write this the figures for the major share of demand are CCGT 27.29%, Wind 23.6%, solar 17.71%, Nuclear 16.1%, Coal 0%. Nuclear is clearly becoming an also ran in the energy stakes!
|Thread: Where is best to buy??|
If you want the best price, buy direct from the maker, third parties often charge more for acces to their selling vehicle than the maker makes on his product!
|Thread: Oh bugger, I told you I was ill|
What an Ebay hero!, I have met the surgeons knife many times, but it gets no less nerve wracking1 It is done now, take it easy and allow yourself time to recover. Good luck young man!
|Thread: Rage Evolution sliding saws|
For the price of these saws of dubious Quality you could pobably get a single phase Manchester Rapidor, which is vastly superior, provided you have the floor space, and will cut anything you can put in its vice, and the blades last for ever!
|Thread: Should I have 3 phase supplied to my house?|
The reason we have gone back to all metal clad CU's is that the ex-spurts did not realise that when an rcd or mcb fails, as all mechanical devices eventually do, they do not fail safe, and catch fire! A fuse always fails safe, but they are the EX-spurts, so they must know best. Pity the poor people who have just paid out a fortune to have their old wylex removed, and replaced by a brand new plastic CU. Good business for the fire brigades I suppose. Never known in 50 odd years experience for a consumer unit to catch fire with fuses in it, even when some idiot connects a 10kW shower to an old wylex, all they do is smoulder and give off a really offensive odout which leaves one in no doubt that something is wrong!
|Thread: Getting rid of the garage door...........|
one of my doors was an up and over, swapped it for a s/h roller shutter, cheap, and more secure, and plenty for sale!
|Thread: Oh Dear, I've blown the chop saw...|
Check between the comm bars and the armature spindle for leakage, preferably with a megger, armatures usually fail to earth when they overheat and the varnish melts. also check continuity through the field coils, and to the metal laminations of the field coils.
I would recomend everybody to do some research, especially on Edison, a brilliant self publicist with a very active worldwide network of offices that fed information back to him and his team about what was in development throughout the world, so he could get first US patent. A very smooth operator with a very musky odour!
BTW, not intended as a "Tirade" just observations really. I don't get what quantum physics has to do with GPS, we were positioning accurately to a matter of a few feet shortly after ww2 using ground stations, in 2 dimensions, the ability to launch sattelites increased this to three dimensions, and meant that terrain did not get in the way. Turing was a genius mathmatician, but could not have built the computers he needed, but he was able to get his ideas over to a clever GPO telephone engineer, who built the first computer since Babbages attempt at the mechanical one.
Basically, Wot Neil said!! But some observations. Edison invented nothing apart from his telegraph device, that was not already working somewhere in the world, he merely obtained the first American patent on that thing by getting his team to come up with a quick working prototype and rushing to the patent office! Maxwell was a mathmatician, Steinmetz was a mathmatician and experimental engineer. The lone inventor is all but extinct because of the patent system. It has become possible to patent ideas without any proof of concept, and so teams of company scientists are involved in this process daily, (IBM are one of the biggest) with the result that no company will fund research into any area that already has patents owned by another, and if anyone does come up with something that works, they can use their legal and financial clout to make your invention come under their patent. I have a friend deeply involved in traffic management systems, and he and collegues worked on an idea for several years, which they patented, for a bus navigation system, which they showed to a major european bus manufacturer. They changed a chip in it, stole the device, and said, ok so sue us! The possesion of a patent means nothing unless you can afford to defend it succesfully in two or three cases, and as Mr Dyson has found out, that costs millions. There is no such thing as Artifical intelligence, that is the hype that makes people believe it is clever. It is merely a machine functioning as it has been programmed, and you can program a machine to write its own program, but it is not capable of thought, it is just crunching zeros and ones very fast. The self driving car, like nuclear fusion, is only twenty years away, and always will be! It requires consciousness to drive a car, not just inttelligence. I have been looking for some proof of this for some time, and found it in some recent discoveries in Neuroscience. If you take a subject with a damaged visual cortex, who has no vision whatever, but has perfectly working eyes, and sit them in front of a screen, you would imagine that you could play anything on the screen and it would have no effect on them, and you can, except that if you show them an attacking predator, they immediately recoil from it, but when asked, say they saw nothing, and do not know why they recoiled. You need this sense to drive a car, how are they going to build that into a computer? By the way, whilst there are theories about magnetism and electricity (and gravity) no one has come up with an explanation of what they are and why they occur, they have merely been quantified Tesla, Heavyside, Steinmetz and Maxwell all denied the existence of the electron, and their calculations are no less correct for it.
