I use Windows 10 on my desktop and always have my user folders ( my documents, pictures etc) on a separate drive to the system and I have just installed Solid Edge without a problem. I do not think that Solid Edge does need to or actually does access the Picture folder, certainly not in my case.

…

Me too, but I didn't use folder redirection to achieve it. Although the system has two discs, all my folders are addressed conventionally, not by telling windows that a folder addressed as if it's on the C: drive is actually located on drive D:

Did you use folder redirection on C:…/Pictures? If so, my diagnosis and solution is probably wrong.

The most likely reason Solid Edge uses the Pictures folder is to save images – model views can be saved as BMP, JPG etc, and it also does animations.

Most applications save Pictures, Music and Videos in the folders provided by Windows for that purpose. I'll try to confirm by saving an image to see where SE puts it.

I think what's happening is that the SE Installer checks that the file system is tickity-boo before starting, and it's bombing out because Zan's Picture folder isn't available in SE compatible form because it's been redirected. (Bit like telling the Post Office to redirect mail after moving house, only to find that Amazon and their ilk don't follow PO redirects.)

Thanks Dave. A comprehensive reply, Not sure about messing with cod and dos! Tried to move the pictures from d 1 tb to c: but the sad is too small to take the 57 k photos…….didn’t realise there were so many!

just looked at GUI and don’t like that either even doing a google search displays a lot of very complex info, most of which seems a foreign language, even though I used to do loads of dos mods with – dare I say it- windows 3.1…….

I’ll hang fire and see if other experts can give me a hand

thanks again

As a Windows expert hasn't volunteered yet, let's see what a Linux fanboy can do!

I looked up 'folder redirection' last night and also found a mass of complicated advice! Microsoft's online help is particularly unhelpful, basically an overview of how redirection is managed on a server in combination with a bunch of other complicated set-ups rarely seen outside a corporate computer room. Full throttle system admin, using Group Policy and other big computer controls most Windows users don't need to know about.

After half an hour I learned redirection can be used to distribute files across discs and across the network in complicated ways, but couldn't find an example.

Having slept on it, I decided "it can't be that difficult", so here I am on Windows 10. Quite often file management stuff can be accessed using File Explorer to open a file's Properties, so I tried that first. Bingo, but it requires several steps and you may not feel it's worth the effort!

Open File Explorer:

Go to the Pictures folder (left ringed in red), and right click it. At the bottom of the pop-up list, left-click Properties, which will open the Pictures Properties dialogue. Left-click the 'Location' tab (red-ringed), and note what's is the lower text-box, also ringed in red. My computer is set to "C:UsersDavePictures", your's – if I'm on the right track – will be something like "D:UsersZanPictures".

If it is, IMPORTANT, take a backup copy of whatever is in the D: folder. Then delete the contents of the D:folder/

Back on the location screen, change the folder to "C:UsersZanPictures" and click the move button. This will move (transfer) the contents of the D:Pictures folders, to C: Won't take long because the D: folder is empty. After the move has finished, the C: folder is no longer redirected. Now install SE. Fingers crossed, now Pictures is just an ordinary folder, not redirected, SE will load.

Last step is to go back to the File Properties Location tab and redirect c: Pictures back to the D: drive, and then to finish off by restoring the backup taken earlier.

COMMENT.

I guess Zan's computer came with a small fast expensive SSD on which is stored the Windows operating system, and a much larger, inexpensive, but relatively slow Hard Disc Drive on which user data, like Pictures, is stored. This is a good arrangement, exploiting the virtues of both SSD and HDD to get high performance at reasonable cost. It's how my computer is set up, except I didn't redirect Windows Pictures to the Hard Drive because all my photos are managed by Linux.

May be a booby trap though! If the computer is bought to run CAD, or any other application that doesn't recognise redirection, the owner might find it can't install. It's a configuration problem, nothing wrong with Windows, SE, SSD or HDD other than they're combined in way that SE can't deal with. Not just SE – I found last night that the Autodesk website says none of their products support folder redirection.

Why is nothing ever easy?

With luck a Windows expert will know of an easier way of sorting this out. It's possible my answer isn't the best way of doing it, in particular I think a system admin would write a script to perform the actions rather than use the GUI. Though I'm sure they exist, I don't know what the commands are!

Hi I have been trying to download this, but it halts very early on with

Error 1606. Could not access network location D; Pictures.

The only option then is to cancel and finish

I have a fast modern desktop running W10 The program is needed to test an assembly which can’t be done in the free version of fusion 360, and I am very familiar with it as I taught GCSE and A level students to use an earlier version a good while ago now

Ps I even put it into the said location and it still wouldn’t go  did the obvious, restarted the computer  etc

Any ideas?

thanks

…

The question here is exactly what was the standard which the new 1799 1 metre standard created against and how was this exacting length measured?????

The goal was to define length in a way that could be recreated by anyone who had the specification. Assuming that the earth was a perfect sphere, this was done by measuring a quadrant and dividing it by 10 million. The quadrant can be measured in any local unit, foot, yard, toise, mile, or handy length of chain. The local unit, whatever it is, doesn't have to be accurately defined: that comes from the big divide.

The earth's circumference is 24,859.734miles or 40075.017km or 22263898 duffers laid end to end. Any of these divided by 40,000,000 is a metre (roughly)

Unfortunately, the 'anyone can create a metre' idea failed. They soon found that the earth isn't a perfect sphere, so the metre had to be redefined as a carefully made platinum bar and copied. Then started a long difficult search for way of defining the metre that could be recreated by anybody, anywhere, which it now is – just count wavelengths of a particular type of light source. Another failed proposal was to define the metre (and yard) from the length of a pendulum beating at a certain rate; no good – turns out gravity varies with location.

The kilogram was the last international standard to be defined physically. Now all standards are defined in ways hat any suitably equipped laboratory can generate.

Zan I think a risk is that Swaps page(s) might quickly become unwieldy before adding tool borrowing messages but I can see the appeal of borrowing tools. I have heard of other sites that offer DIY tools/ladders etc lending hookups. However I do think a separate tool Borrowing Request page would be a good idea and presumably operating locally would reinforce the local ME community/social ties.

Zan, first I turned an outer rim from 1/2" wall tube with a 0.25mm step on the inner face

I then turned the inner rim from the piece of 1" wall tube to fit inside the outer ring. I was able to part off the piece I needed and save the other bit for something else, left the last 0.5mm of wall to cut with a hacksaw

The inner rim was then drilled 9mm for the small end of the spokes and countersunk

The hub was turned from 35mm stock, rough drilled 10mm and then drilled and tapped M4 with a counterbore for the larger 10mm dia ends of the spokes

Spokes were from 10mm dia stock, faced to length, ctr drilled and the ends tapped M4 (hub) and M5 (rim) before reducing one end to 9mm dia and finally taper turned

I got carried away and did not take an assembly photo but basically the inner rim was held in the 4-jaw, spokes slipped into the holes, hub then supported on a bit of 10mm rod held in the tailstock chuck.

M4 studding in the ends of the spokes allows them to be screwed up to the bottom of the hub counterbores with a smear of JBWeld. M5 csk socket screws then screw into the other end of the spokes and seat against the csk holes. Final hub position can be adjusted by how tight these screws are done up – a bit like truing a bike wheel. Smear of JBWeld on this joint too

The two rims were then slid together with the step previously turned ensuring the inner ring is sitting true and equal about mid point of the outer rim. Loctite used for this joint. Doing it with the inner and outer rim allows all the holes to be hidden.

Once set back in the 4-jaw for a final skim and bore hub to final size, then broach keyway. I still have to add a small fillet of filler around all the joints for that "cast" look

It works!

This all make sense now as the original owner (my father in law) was involved in the galzanising industry and was sent to the USA after the war to learn of the latest American techneques and this gauge was an item he took with him.

In clearing out my workshop I have found a number of tools and jigs both inherited or made that have been used once i the last 50 years but that I am unale to throw out.

[Ramon WilsonParticipant @ramonwilson3]

Hi Zan, Jason,

I wasn't aware that the John Tom site was no longer available. If you are talking about the marine engine article I have them on file so could easily send you copies of them if you let me have your email address.

Good luck with your Mc'Onie – a lovely engine but do check the measurements on width build up between the frames as there are one or two that can lead you astray. Also the position for the governor pedestal – that's dimensioned off the edge of the baseplate at opposite datums. Position it relative to the (assembled) crankshaft position for best results.

With the complex valve gear I expected mine to have issues with the set up but I worked to the drawings on all components and it ran straight off.

I've actually received – and sent – nearly as many real cards as normal, approaching 30. Two less by deaths, about 8 or 10 by hand, rest posted.

Cost of a stamp?

Shall we stop and think rather than demanding something for nothing..? It only seems costly when we post a lot in a very short time, such as Christmas cards. To be honest I am not sure of the price of a 2nd class letter stamp but for what it buys, it is remarkably cheap. It is the same whether you are posting across town or from Penzance to Lerwick..

Whilst I accept it is not perfect and strikes hardly help, had Royal Mail been handed to TNT or some other overseas industrial courier as wanted by one past Prime Minister you'd not expect to do that, you can bet more than a First-Class Stamp it would cost a lot more. Other threads on here also suggest you'd probably find the cards a soggy mess in the front garden! The presents too – if not left for you to try to trace, and collect from a warehouse 50 miles away.

Rowland Hill's first universal service initially cost 1d a stamp. I wonder how expensive that was, pro-rata, at the time.

Anyway how much more than normal through the year, do you spend on the event anyway – food, gifts, drink…?

''''

As for feeling jaded, well, yes I can understand that.

The origins of the Christmas we know are the Jesus story imprinted on Northern European pagan turn-of-year celebrations, a heady stein of 19C German merry-making and the Dutch, Saint Nicholas (my Anglicising, and he wore green not red). Sadly now crushed under far too much meretricious, gimmick-ridden, pseudo-sentimental American supermarket / show-biz / "Santa Claus" tripe.

I think it was neatly summed up by a Punch cartoon published quite some years ago. It depicted a couple struggling home with bulging bags of Christmas stuff. The husband is saying,

"What happened to the magic of Christmas? We weren't paying for it then!"

When I did an aircraft course, many years ago now, I remember during the cabin conditioning and pressurisation phase of the course being told that a fluid (for that read air) will more readily give up heat the hotter it is, in the system on the particular aircraft that we were training on the cold air unit in the air system actually heated the cabin air before cooling it as this was actually more efficient at achieving a cooler temperature, bearing in mind that all the cabin pressurised air was taken from the compressor stage of the engines so was starting out 450 degrees C. It didn’t make sense to me then and still doesn’t. Dave W

Dave, it turns out we are not the only ones mystified. But yes hot water apparently does freeze faster than cold water under many conditions. Even the scientists are mystified but recognise the effect, and have named it the Mpemba effect after a Tanzanian "discovered" it in 1969. But it has been known apparently as far back as Aristotle and no doubt beyond. But the scientists are still grappling with the "why" this happens.

A rundown on the science is here Link

Explanations include Evaporation, dissolved gasses, convection, effect on the surrounding air, and supercooling. It is quite complex and totally counterintuitive.

So it turns out those old blown-away Swedes and Norwegians and Russians who settled the northern plains and mountains of the USA knew exactly what they were talking about. It just took science 100years to catch up.

[Robert Atkinson 2Participant @robertatkinson2]

Zan,

That sounds more like incorrect VFD settngs than too small a motor. Or you are overloading the lathe. Myford recommended 1/2 HP (4 pole) for a 3 phase motor so you are already at 50% oversize.
Running on the smallest pully is not ideal unless you are doing high speed work You should pick the belt position that keeps the motor near rated speed for the work you are doing. Running the motor well below rated speed is not the best set-up.

Robert.

Pitching this post to any owners of the Russian RYAZAN 1M63 Lathe, which is a Soviet-era copy of an older German lathe. What sets the 1M63 apart is the fascinating taper-turning facility which you'll find on no other lathe. Although a comparative walk-in-the-park for modern CNC machinery for a manual lathe the 1M63 uses the little-known combined feeds technique for machining tapers.

Go searching for this on YouTube for instance and you'll drown in videos on all the orthodox methods and everything in between but astonishingly, nothing on the combined feed arrangement as used on the 1M63.

My request is, for any 1M63 owner out there could they please do a descriptive video explaining the features of the driven compound slide followed by the facility in action. Post the link to the video here. I am confident it will be well watched. Also, could they also post all the relevant pages from the lathe owners manual especially any exploded view diagrams showing the internal mechanism.

Novel and almost unique Taper-turning facility.

My working hypothesis is that the ‘lone genius’ Inventor of the mechanism was on his way to the Ancient Greek Patent Office … when the ship sank.

My theory is that a gang of guys at an ancient Greek Model Engineers club got together in their newsletter to design "… this really zany mechanism and drop it in the sea so that when someone fishes it up in 2000 years ….."

Here’s another from my daughter involving text message from strange number

hi mum Iv lost my phone and I’m stuck without funds please will you send me ……xyzzys……….. Iv had to borrow a phone to send you this………

my granddaughter is 4 and needless to say she can’t text or could loose her non existent phone

We had the reverse situation of this a few years ago. We were on holiday abroad & the apartment was burgled, ipad/phones etc taken. I sent my daughter a text message from the people next door's phone, asking her to block our phones. She replied to the text saying she didn't recognise the number & asked the sender to prove who they were i.e. me. I sent her another text with the name of her boyfriend & my DOB. Since then, we have a family password to identify each other in case a similar situation arises in the future. very simple but effective.

Hi Model Engineering Friends

I thought it was time to provide a brief update on this project. Much has come in the way of it including Solar PV with battery, much fighting with our electricity retailer, much work on the improvement of the rear garden, particularly in relation to Builder Shame dating from since the time the house was built rigt up to thelast time we had builders on site, adding the mezzanine floor to the garage, and trying to find door and window suppliers capable of installing kit that is pushing the latest building regs. On the hobby side I have worked with long time steam canoe and mono-tube boiler enthusiast John Emmett on a couple of articles on mono-tubes for the SBA's Funnel magazine. With those done it seemed a good idea to create a website to bring together all kinds of mono-tube steam generator information/views from anybody who is willing to contribute. Having used Concrete CMS before I volunteered to do the basic set up work, but found I had got the latest version (v9) which is quite different to the version with which I was familiar. Steep learning curve time. Anyway the framework and some material is there now and contributions will be welcome: https://www.mono-tube.org.uk

Having worked with John I am now of a mind to copy his mono-tube steam plant in Snipe but using the existing Cygnet. As work on that starts I will keep you posted. A picture below:

Best wishes

Pete
