Thread: How was this recording done?
04/11/2019 15:44:32

Many thanks Pete and Jason, I did not pay attention to this. To my excuse: it is almost unreadable on my display.

I will check out this program and hope I can use it also.

Kind regards,
Hans

On 3/11/2019 08:24:34, in thread "Learning CAD with Alibre Atom3D", JasonB inserted an interesting video. We see what I think is the Alibre window on his computer, and the actions he performed are shown with a large mouse pointer in a yellow circle. I suppose that is not the standard Alibre pointer (or is it? ).

I hope that inserting that video here works, if not - sorry. 
Ok, I see the link, but I hoped for more...

What I would like to know is how such a video is done. A couple of days ago I learned that something like that van be done with the well-known media player VLC. Unfortunately when I tried that the mouse pointer was not visible in the video, and so it is not suitable for demonstrating something to a viewer.

So, Mr. JasonB, can you tell me how did you produced that video?

Kind regards,
Hans

Thread: Blimey! It's never straightforward...
31/10/2019 17:29:49

Forget that Cura, and download PrusaSlicer from the Prusa website for free. I did so, and forgot my non-working example of Simplify3D. Although I often think I should really make a screen-video and show the world how useless that (not cheap) slicer is.

Hans

My latest W10 update has added a new item that I've not seen before when you ShiftKey+Right Mouse Button in an empty space in a folder in the "file explorer"....

"Open Linux shell here..."

And it does as well...so I can ls -l, ps -ef, grep, awk etc in my windows folders from a command line

I was quite interested in this remark by MM57, so I did a complete update of my W10. Up to now no adverse effects (touching wood).

But when I do the steps above, I don't get a Linux shell, but a window with a "Windows PowerShell".

I'm beginning to think there are different variants of W10 around...

Kind regards,
Hans

embarrassed shame on me, but as the postings before are from Oct. 2019, it's perhaps excusable.

I'd suggest waiting to see what we announce in the next MEW before making any spending decisions

Neil

Well, supposing that the 'next MEW' is issue 286, which arrived here today, I was searching back and forth for this announcement, but found nothing. Or can someone tell me what I missed?

Kind regards,
Hans

Thread: Q: Print Nozzle Hole Shape?
31/07/2019 22:25:51

Uh-oh- if using a square hole in a printer nozzle, wouldn't it be necessary then to rotate the nozzle so that it is always tangential to the movement of the print head...?

Kind regards,
Hans

Thread: Removing Broken Tap
28/06/2019 10:54:01

What do I know... but I think it is bad practice to use serial taps in Stainless. Parts of the unfinished threads get work-hardened, and then good-bye...

Just now I have 48 tubular 'thingies' in the workshop, at least 3 different grades of stainless steel (scrap from the merchant), diameter 16 mm, which should get a M12 thread at least 20 mm deep, I drilled 10.5 instead of the standard 10.2 mm, and will do the thread in one swoop with a machine tap. Can tell the outcome in a couple of days, if it still interests someone...

Kind regards,
Hans

Thread: Making a Start in FreeCAD
20/06/2019 17:28:33
Posted by Ron Colvin on 20/06/2019 15:22:18:

Onshape is free to hobbyist the biggest restriction being, that the free subscription only allows public data. in other words anyone has access to your work.

Yes, what you said is true, but as I think there are thousands of users, and afaik it is not possible to search the enormous list of public drawings. If you want to be safe(r), just give your work a meaningless name.

I had also a look at some Fusion videos, and there and also in FreeCad the author(s) emphasize the importance of 'constraints'. Onshape also uses constraints, but you use them only if you really need them (e.g. make a line tangent to a circle, or parallel to another line, or 2 circles concentric.

Another point: I think it is really easy on Onshape's site that it is absolutely free for private use.

Regards,
Hans

I think SOD's tutorial is really what is badly needed for FreeCad. But I really wonder every time why Onshape is never mentioned here (except by me I think!).

I just did SOD's example in Onshape, and it is so much easier. The only thing I would do differently next time would be the cross bar. I have it visually correct, but the build tree shows an error.

Unfortunately I don't know how to insert screen pictures here (except via long winded procedures), but as it is a public part, anybody using Onshape can see it (under SODexample).

Kind regards,
Hans

Thread: Is CAD for Me?
05/06/2019 00:00:56

Aah - after reading all that stuff and shaking my head in disbelief I decided to 'design' Nigel's bush in Onscape.

I have to add my comments above as I don't know how to write something below a .jpg
And the two pics are not in the correct succession...

So the second one is the result as it is shown in Onshape. The dimensions are in the (now invisible) sketches.
The first one shows the automagically generated 2D-drawing, with some embellishments added on that stage (hidden lines, cutout) The dimensions can be placed where one wants them, and their values come from the sketches!

Apparently although Microsoft have officially ended free upgrades to w10, they haven't switched off the free uprade licence validations servers - essentially 'accidentally' allowing (the great majority of) late upgraders to still take advantage of the offer.

Neil

Hello Neil,
I'm quite interested in what's behind this remark above. When I bought my laptop, it came with Windows 8.1 My (newer) desk PC has W10. Because of the (at that time) frightful remarks about W10, I let the offers to update pass...
But now I would like to, if I could.

To make it short, could you give a hint (read: link) where this upgrade is still possible?

Kind regards,
Hans

Thread: Anodising
04/05/2019 23:08:47

Reading that UK law above makes me shudder... I can go to the nearest chemist's shop and get acids over the counter, no problem. 1 kg of H2SO4 they had to order from their supplier, and nitric acid they had only a small bottle (1/4 l) in stock.
Btw. when you leave some of that 15% acid in an open bowl, the water dries away and the concentration will go up. At some point - which I don't know where it is - there will be an equilibrum between evaporation and water absorption due to hygroscopicity (what a word...).

And in contrary to a widespread belief H2SO4 is not ccorrosive. What was the name of that famous model engineer which put his loco 'Como' in a glass box together with a bowl of concentrated H2SO4, to keep the humidity low and the rust at bay?

Hans

Thread: Black Holes

Posted by Neil Wyatt on 12/04/2019 18:03:19:

... It's the light from the accretion disk BEHIND the black hole being bent around the event horizon...

Hi Neil,

Isn't the word 'light' in the sentence above a bit misleading? Afaik a radio telescope doesn't see 'light' in the sense we usually use that word. I suppose the black hole picture is a computer generated picture from whatever electromagnetic waves they received.

If I'm wrong, I am eager to learn more...

Hans

Thread: (Almost) every year MEW subscription
30/11/2018 22:48:38

Hello all,
I'm glad to report that almost exactly after two months I can hold my missed MEW issue 273 in my hands.
All OK for now, at least until next autumn when my subscription is due again.

Many thanks for all who helped (especially Neil).

Kind regards
Hans

I am very sorry having to add a new chapter to this endless story.
After clearing the issues with my subscription and account I waited for getting the next issues of MEW, but nothing happened. So around the end of October I contacted MTM via the answer form in the account. Quite fast I received a email from a Ms. Buckley with the following statements:


>> I am sorry to hear that you have not received issue 273 I have reordered this again for you today.
>> please allow up to 14 days for delivery to Europe.
>> If there is anything else that I can help you with please don’t hesitate to contact me.

Well, 14 days, ok maybe they send it by horse coach, but better than never.
So after almost less than 14 days I found an envelope in my letterbox, which pleased me no end. But not until I opened it: They managed to send me issue 272 a second time, and not a hint of 273 and 274 (which I believe is already in circulation too).

So I sent another email to Ms. Buckley, which I copy here too:

>> Dear Ms. Buckley,I was very pleased to find an envelope from MTM in my letterbox. But unfortunately I
> was not much pleased when I found out that I received MEW issue 272 instead of 273.
>> I'm very sorry to ask you again to send me issue 273.
>> I take this opportunity also to report that I also have not got issue 274. I have to suppose that there
>> is a big mess with ma subscription.
>> Thank you very much for your help in these matters.

Now I will see what happens after the next two weeks, but I slowly get the feeling that my subscription is for the foxes as we say here.

Kind regards,
Hans

All ok now (I believe...), could even have a look into my account. The mail addr I used for the subscription did not work for the account, strange but I can live with that.

Many thanks for the help

With Neil's link above, and using another email address, I could (successfully???) start a new subscription.

Setting up an account (to check at which time the subs starts) was not possible, though. The 'Thank you' email gives no information about this. So I wait with bated breath if the issue 273 lands in my letterbox. If no, then I would need the help of a good-natured soul who would buy it and send it to me. All expenses covered via PayPal...

Regards,

Hans

07/10/2018 16:47:41

I repeat: it's not so easy!

When I use the link from MEW272, page 53, I only come to a subscription page for Model Engineer. What has happened with the one for MEW!!! The link contains the letters 'mew'...

Slowly I'm getting really grumpy!

Hans

07/10/2018 16:21:42

Ah, it's not so easy...

Yes I got an email with a link for resetting a password (if I have one, what's not so sure). but I was away from home last week ant the email had a terribly small time window of 6 hours...

Now I'm in fear to loose MEW 273, as this has not arrived here and I don't know when my subscription ends.

I'm trying now to get a new subscription with a Gmail address.

Kind regards,

Hans
