Thread: Drilling small holes in hardend steel
17/02/2020 22:23:54

It's nice to see that Mr. C.T-T finally also has learned how to quote correctly. For such an old git like me it is really cumbersome to find out who has written what. I sincerely hope that from now on, as you wrote, you will move on.

Kind regards,
Hans

Thread: Where to acquire a small amount of bromine
06/02/2020 17:28:17

Used to make it myself when I was 13 years old (read: looong ago...). Cant remember the method, but most probably the one using KBr, MnO2 and sulphuric acid. See Wikipedia.

Kind regards,
Hans

(still around, no self poisoning...)

Thread: Stuck Chuck
07/01/2020 15:57:35

Two pages discussions about removing a stubborn screw? The OP didn't show his kitchen vise, but if it is anything usable I would:
- remove two jaws
- clamp the remaining two (180° naturally) in the vice
- file two flats on the protruding part of the screw (don't think these adaptors on a Sherline are hardened)
- use a wrench, mole-grip or what-have-you and apply torque! (in the correct direction...)

I don't think the financial loss would bring someone to tears.

Kind regards
Hans

Just to show what's going wrong: here a picture of the limits and fits button. 

Oh the troubles, when the .jpg is too big, nothing happens. 

Kind regards,

Thread: Reamer size questions
03/12/2019 14:38:59

I can only repeat the numbers given by Steve above, 6.33 mm for a drive fit for a 6.35 (1/4" ) shaft.

Kind regards,

Thread: Any users of the 'ModelEngineersUtilities here?
03/12/2019 14:14:56

After several tries with the hints given here (installing as administrator* and unpacking into an 'ordinary' data file) I have, on Windows 10, still the same results as described by Thor above.

But, doing the same on my W. 8.1 laptop resulted in a correctly running program! All black on white background, fully usable!

Still wondering what's going on here. As it was running correctly for many years, I suspect 'something' was updated some time back.
Altogether again an example of the help one can get here; thanks to all!

(*) On W10 I had first to find out how to install myself as administrator, but the laptop has 'execute as administrator' in the context menu!

Kind regards
Hans

I have this small program on my computer (W.10) since umpteen years. It shows as version 1.8.0, seems this is the latest version. When I wanted to use it now, I had to discover that it stopped to work correctly. Some of the buttons display now a black background, and the 'captions' are invisible, and 'calculate' does nothing.
The link given in the program (www.alanjmunday.info) is invalid, but a bit of searching found a download site in software.informer.com.

software.informer


I tried to load it from there on my Laptop (W. 8.1), but there I could not even unzip the file...
So I would like to know if there are other users of that really useful piece of software (when it works!), and if they have the same or better experience.

Kind regards,
Hans

Thread: Reamer size questions
02/12/2019 13:04:44

Dear Mr. Evripiotis,
well I will do my best. First, to my big grief I had to discover that the M.E. utilities stopped to work correctly. Some of the buttons are ok, but the 'Limits and Fits' are now unusable. It is the latest version, and is on my computer (W.10) since umpteen years. I tried to load them on my Laptop (W. 8.1), but I could not unzip the file... Some of the buttons show now a black background, and the 'captions' are invisible, and 'calculate' does nothing.
It would be worth an own thread, why a program suddenly can stop working correctly.

Now to the reamer problem.
One address I know is the Brütsch, Rüegger toolshop:

brwtools

The other is the manufacturer Re-Al:

Re-Al

Hope I could help you a bit.

Kind regards,
Hans

Seeing just now that my link above does not work. But the utility can be found here:

As far as my knowledge goes, a H7 reamer has a positive tolerance from the nominal value. So you would hardly get a 'tight fit' (whatever that is) with such a reamer. I don't understand why you don't jump on the metric reamers in 1/100 mm steps. I could name easily 2 or 3 shops in Switzerland which send tools anywhere in the world.

About fits in general, there is a nice utility called ModelEngineer's utilities (www.alanjmunday.info). Enter your values and see what you need.

Kind regards.
Hans

Thread: which lathe?
27/11/2019 22:07:22
Posted by jamie creighton 1 on 27/11/2019 19:11:34:

could you guys advise on what lathe to go for that will turn to tight tolorences.

Turning to tight tolerances lies in the hands from the one at the handles, more than a problem of the lathe itself. Anyway, buying a lathe for repairing or rebuild a turntable bearing is a very expensive proposition!

I built several turntable bearings myself, although not with such complicated housings (which would be very difficult to making on a lathe). But I can say that I used Delrin (and Torlon, if you can find and pay that stuff!) with very good success.

Kind regards,
Hans-R

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...

https://youtu.be/KBZ8ElBzLzU

 

 

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

Thread: windoze 10

Posted by MM57 on 14/10/2019 20:20:20:

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

Thread: Fusion 360 Licence Changes

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
