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

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.

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?

Regards,
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

08/10/2018 21:47:11

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

,Hans

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

A couple of weeks ago I got a nice letter from Mytimemedia to renew my MEW subscription.

Unfortunately I misplaced this letter, but that shouldn't be a problem I thought.
Took out my confirmation letter from 2017, where I found my subscription number
(but unfortunately no specification up to which number this subscription runs).
So I went ahead in this secureorder mess, filled out all forms to the best of my knowledge (choosing Continuous credit/debit card),
and finally was greeted with the following message:

"Sorry, we are currently unable to complete your order because either we don't ship to your country
or you have products with mixed payment types in your basket."

As neither of this is true, and I am not able to clear these problems by telephone, I wrote an email to
help@me.secureorder.co.uk.
I received - only a couple of days later - an answer from a Ms. Buckley, which wrote
firstly about a ME subscription (which I don't have), and secondly gave the following advice:


"Subscription xxxxxxxxxx for Model Engineer Workshop was set up as a continuous credit card but unfortunately this was declined on the 5/9 if you
can please call us with new card details we will be happy to put this through for you."


Now it is true that I use a new credit card, but found no way to delete the old number.
So I wrote back to Ms. Buckley, stating that I can't do that by phone, and gave her the correct credit card number.
Should all work now I thought... Again some days later Mms Buckley answered with that remarkable statement:


"Dear Subscriber,
Thank you for your recent email.
If there is anything else that I can help you with please don’t hesitate to contact me."...

So that's going full circle now, and unnecessary to say that nothing works. When I try to open "Myaccount", I'm asked if I hhve a password.

I mark the button 'no', but on the next page I have to enter a password.

In my desperation I tried to buy a new subscription, even if then I get some issues twice.
But this also does not work:


"Not possible to register xxx@xxx.ch. Maybe you have registered already previously?"


So somewhere in the big data mess my email is registered in all eternity.
I seem to remember that some years ago I already went through the same hell.
Now I see only the following possibilities:
- Neil can come to the rescue and clear this mess.
- I use another name/account from my household (SWMBO), but use my credit card.
- I use one of my Gmail accounts (which I don't really use...)
- I use a throw-away email account. Possibly the best, so all further mails from MTM land in the big bit bucket.

Regards, grumpy Hans.

P.S. I've just seen another thread about similar problems, and Neil's answer is exemplary: Just make a telephone call....

Is it so difficult to understand that it's not possible for everybody on the whole earth to make a telephone call, when both parties understand possibly 30% what the other side says...

Well if the 'A' could also be a 'V' (seen from the other side), then it would be Schaublin. Possibly W20?

Thread: A beginners' guide to aluminium anodising?
20/07/2018 00:01:24

Go ahead with anodising, it's not too difficult!

I remembered that (quite some time back) I put a picture from my first trial in my album. A small test piece, coloured with magenta Inkjet ink. I added now another two, showing parts from my tonearms. The blue parts are also done with inkjet ink, blue this time

The parts on the other arm are coloured with products from The German firm 'Electronic Thinks'
Black and Titanium colour, which is more like dark Bronze.

**LINK**

Here you can get all what you needs for your anodising projects.

Btw. I made some tests with those textile colours, but no success. It seems that only one of the different Dylon (?) products can be used, and it seems this one is difficult (or impossible) to find.

OK, here then the pictures:
Sorry for the dust, i did my best to clean all before taking the pics, but with flash one sees the smallest speckle...

Thread: Todays Mystery Object?
19/07/2018 22:00:13

To continue with the thread drift. if you allow:

I always wondered what units one has to use for E=mc^2 to get a meaningful result. In SI units it would mean E in Joule, mass in kg, c in metres per second... but is this correct?

Thread: Cataracts [ocular, not Hardinge]
30/11/2016 23:06:59

Hi all,

it's a bit depressing to read about all that successful cataract operations. So I can keep the balance to show one which went belly-up.

About 5 years ago my eye doc found it necessary to talk me into a cataract surgery. I had the usual fears, but finally succumbed and went ahead. But afterwards I had the feeling that something was wrong. Straight lines were not straight, circles were more like eggs, all persons on TV had flat head sides etc. etc. Naturally I immediately cancelled the second surgery date. A long series of tests followed, culminating in a second surgery in which the glass body in my eye was removed. Unfortunately the success was almost nil.
One of the tests was a laser scan of my retina. This is what it looks now:

retinacut.jpg

The upper wavy line is the retina surface. Maybe you can understand a bit what kind of 'picture quality' results from that. A further problem is that part of my short-sightedness was corrected with the artificial lens, so I have now two very different apparent picture sizes in my eyes, which somehow the brain tries to overlay. Estimating distances is quite difficult now.

I don't want to bring panic an all those who stand for that decision, but unfortunately the docs never tell what can go wrong. 999 out of 1000 come out well, but if you happen to be the one...

Kind regards,

HansR.

Roderick is absolutely correct, Castolin/Eutectic 1801 is equivalent to the famous Easyflow. Luckily it is still available without problems here in Switzerland. Maybe you will get it back after Brexit? cheeky
