Thread: Explorer 9
21/06/2011 13:28:48
A snip of some of the actual wording from the Microsoft website and the text continues with the ways the issue can be resolved.
Some websites may not behave as expected in Windows Internet Explorer 8 or in Windows Internet Explorer 9. This problem does not occur in earlier versions of Internet Explorer, and the affected websites continue to be displayed correctly and to work correctly in Windows Internet Explorer 7.

For example, you may experience any of the following symptoms in Internet Explorer 8 or in Internet Explorer 9:
  • Menus, images, or text are in the wrong positions on some websites.
  • Some website features do not work.
  • You receive script error messages on some websites.
  • Internet Explorer stops working on some websites.
Some websites are designed for older browsers. You may experience compatibility issues on these sites until they are updated for Internet Explorer 8 or for Internet Explorer 9.
Internet Explorer 8 and Internet Explorer 9 include a Compatibility View feature that displays websites that were created for older browsers as they were designed to appear with Internet Explorer 7. You can enable Compatibility View in Internet Explorer or on the Web server...

I find some the beauty of having the dxf files lies in being able to print off drawings as and when needed for use in the workshop, without fear of damaging the original. They can be made to a convenient size and have superfluous data removed as required, as well.
I think they could - and should be made available here. Maybe even sell them (nominal fee of course) with a 50/50 split for the author and publisher?

Thread: Gib Adjustment - how tight is too tight?
17/06/2011 15:26:36
Sorry chaps, but I can't imagine what improvement you could expect by putting ball bearings in there.
If you're sure the lathe isn't worn, then I'd suggest you keep it simple and adjust the play out with the screws as designed and provided by Myford.
Because I find locking nuts infuriating, the one thing I do on my own stuff is remove them and apply a bit of that blue thread lock to the adjusting screws. That way they become stiff to turn, but remain easy to adjust.

You can fiddle with the screws 'til the cows come home and still not be happy.
The best way of adjusting the slides is to nip the adjusting screws down so that movement is just a little tighter than you need and then tap the slide (on the same side as the adjusting screws) with a mallet or hammer + wood etc to reseat everything until you get a nice even movement.
It's how it's done in the factory

Thread: Arc Euro Trade High Speed Spindle Motors
14/06/2011 22:59:50
I've got the equivalent Chinese motor and inverter combo from Ebay that John mentions.
To all intents and purposes runout is non-existant, as is motor noise, so I imagine the Arc Euro products would be as good.
As an indication of how little noise emits from the motor at full speed, I can tell you that the cooling fan for the inverter is noisier and the cutting process is far more significant in its contribution.

The cycle computer used in the article has an RPM feature and so doesn't need calibrating.

Assuming the old nut was still usable: Bolt it to your miller bed and in alignment with the (also bolted down) bore of your new nut. You could somehow attach a single point cutting tool to the end of the threaded rod (a bit like a between centres boring bar) and use it to cut one of the starts. Repeat the operation seven more times by indexing the threaded rod within the old nut.

It is a pity that this information hasn't, as far as I am aware, been presented in MEW in this type of format. Rather than showing screen shots of computer screens with code etc. a simple explanation of what is required and the relative costs would encourage some to take the plunge into the CNC way of producing widgets etc. While I can't justify the expense of going down the CNC route, nor do I have the room, I would certainly be interested in reading an article along these lines.
Not so much about what is produced but the setting up the component parts and how they interact plus relevant/typical costs for a small workshop environment.
In one of my earlier post I classed myself as a CNC Luddite, not because I can't see the advantage of CNC but more because what I produce doesn't warrant CNC and while I am still learning I get great pleasure in hand mangling bits of metal.
I have supplied an article along these lines to David at MEW, but I don't know if or when it might be published.
In it, I've tried to show how a part can be draw quite simply in an (affordable) CAD program and transfered to an (affordable) CAM program, to produce the instructions (G-code) for the CNC milling machine/router to run.

As John S. points out, there's virtually no need to look at, let alone fiddle with the code once the CAM has produced it. The whole point of a CAM program, is to relieve you of the tedium of figuring out the right numbers and appropriate instructions and allow you to concentrate on other, more important things.

Thread: DRO,s fo Mini Lathes.
20/05/2011 14:07:10
Whilst not as elegant as a more expensive setup, I'm finding (the one) I have fitted to the cross slide of my Clarke CL300 lathe to be quite useful and accurate. I haven't fitted a DRO to the top slide because of it's bulk.
If you forget about trying to use them in the way you would a 'professional' DRO and think of them simply as 'digital dials', i.e. allow for backlash, then they make some sense. Don't forget they work in imperial and metric too and are switchable at any time.

Frankly, this says more about the mentality of some people rather than the reliability of Windows software. After all, if a stranger took a hammer to your Mac and destroyed it, then you'd surely agree that it wouldn't be fair to blame Apple for that - I think the principle carries through in this context too.

Martin - my mentality is fine. I blame the openness of Windows for its vulnerability, not the attackers. If your car wasn't easy to steal they would eventually give up and go away. Linux is more secure because it is a full implementation of the basic Unix dispersed model of access rather than the bodged affair that is Windows. Hence the ease with which it can be subverted. I can harden our Linux installations to stop all but a direct attack i.e. gaining control of the PC past the logon password. Linux doesn't fall over after a simple system update which was the reason for my last visit to a friend to spend 2 hours fixing his Windows PC because the update had disabled its DHCP.

I know there are CAD programs for Linux (QCAD) so I'll give them a look
I was questioning the mentality of the virus writers and those that set out to cause trouble to others - not yours.
I can't agree with your angle on which party is to blame in the event of a virus attack though.
Because of the huge amount of hardware and massive number of software applications, Windows has to try to be all things to all men. Reducing its openness would reduce choice for us all, as third parties would find it harder to develop applications. Because of this necessay versatility, my view leads me to believe it's going to be more vulnerable to the hackers and virus writers. I can't really see that Microsoft would actually want to keep writing patches and updates, but they have to for the sake of their business.
Good luck with the CAD.
Thread: Why did my Flywheel Wobble?
18/05/2011 21:34:48
More than likely a problem with the boring tool, such as a lack of rigidity, wrong clearance angles (which cause the tool to rub), or off centre height, giving 'bell-mouthing', etc.
Could also be hard spots in the casting. Something like that anyway.

Hi Martin

One of my points was that I cannot/will not add the cost of Windows to buying the CNC kit itself. I am glad that John S confirms that CNC/CAD/CAM programs can run on Linux as that is my chosen OS.
I work for a local council for my industrial/business experience of computing and their Windows based PCs don't tend to have problems but the network suffers outages. At home its a different story. I got sick of SWMBO moaning that the Windows PC was slow or wouldn't work because the teenager's internet trawling had loaded the thing with viri and malware. We now have one Mac (using this now) and everything else is Linux as I can install it and maintain it and we have been problem free ever since (excusing the actual failure of hardware).
It's personal choice and I prefer to be using the tool rather than constantly fixing it.
Frankly, this says more about the mentality of some people rather than the reliability of Windows software. After all, if a stranger took a hammer to your Mac and destroyed it, then you'd surely agree that it wouldn't be fair to blame Apple for that - I think the principle carries through in this context too.
When it comes to other O/S's then apart from EMC2, there is very little choice of CAD/CAM/CNC software for the Linux platform.
As far as I am aware, there is some engineering CAD software available for the Mac, but offhand I can't bring any CAM or CNC controller software to mind, as I haven't needed to look.

That's some lovely work you've done there!
As for the Balance Spring, did you ever try wrapping the wire around a threaded mandrel to keep the pitch even?
