Thread: levelling

That IPhone app sounds pretty good Terry, but I think you'll probably agree that Peewee is going to need a proper engineers level to ensure than no twist remains once his lathe is installed.

Hi Hawker John.
If you need some g-code generating, then send me a message and I'll have a look for you.
Thread: Clarkson Chuck - removing the centre

If it really is in that tight, then I would be thinking about setting up a toolpost grinder and either just giving it a lick in position on the miller - or probably easier in the lathe. 
If it's got a Morse taper shank and can go straight in the headstock spindle, that would be an ideal way of doing the job.  
Thread: Which New Lathe; choices, choices...

In view of some of the evidence here and here of these machines being of quite basic construction, I'd be more inclined to try Myford, as something like this is probably cheaper and easier to tool up.
15/11/2010 14:04:34
OK, so you've narrowed it down to just the 3 (possibly 4) machines, as you seem to have ruled out all Chinese made machines. We now need to know which features are causing  you concern, out of the lathes on your shortlist.

The Comet is a slightly smaller machine than the DB-10V, but does have the advantage of having power crossfeed as well as a rather useful looking top slide that has a larger than usual range of travel. The top slide also has machined tee-slots for mounting tooling/accessories, or workpieces for milling. I don't recall seeing that combination on any other lathe in this price bracket.
One other feature that is a 'must have' for me is continuously variable spindle speed, as I find being able to tune out chatter whilst parting off or drilling is very convenient.

Having seen the Chester lathe, I came away quite impressed with its construction and finish.
A hardened bed is nice to have, but plenty of lathes don't have one, for instance Myford and Boxford to name two and It doesn't seem to put many people off owning them.
The main cause of wear is by allowing swarf to get between the moving parts, so keeping things clean and lightly oiled is the way to go.
Remember that you will spend a fortune equiping your new purchase for work, so don't blow all your funds on just the lathe.
Keep us updated with your thoughts.

You'll be able to do that job in CamBam.
There's nothing to touch it at the price, in my humble opinion.
Thread: The Impecunious Engineer

In a similar vein, I was taken aback the other day when I saw that Ty-phoo QT has now been relabled as "Instant black tea with whitener".
Thread: Why is everything you buy such rubbish!!
08/11/2010 09:56:25
In that instance Eric, you would probably find a clause to the effect that no guarantee could be made to the accuracy of the magazine's content. However, if all the text and pictures were badly blurred and/or pages missing etc, then you might have a case.

We live in a country, where for far too long, those in charge have patted each other on the back and rewarded themselves handsomely for services rendered. In their view, their efforts are "world class" and must be acknowledged as so by those around them.
That is how, as a nation, we managed to produce the likes of the Vauxhall Viva, Morris Marina/Ital and the painfully inadequate Sinclair C5, so no wonder the workers at Luton chose the more up to date Japanese produced cars, as they obviously saw the shortcomings of their own products and elected to spend their money more wisely.
If my memory serves me well, poor quality and high unreliability always seemed to be reported as the fault of the workers, but never the management for allowing such rubbish to be designed and built in the first place. Strange that I've never heard the explanation of how companies such as Nissan and Toyota can successfully make genuinely world class vehicles over here though.
It continues to this day, with the financial institutions reminding us of how vital they are to the country, whilst warning us of the dangers of regulating them, as such action would cause a "brain drain", from which we could never recover.
Just as a reminder, I think the "Bonus Season" starts for the Bankers, early in the new year, so do bear that in mind while you check your bank statements for how much interest you've earned.
Thread: What do we really mean when we say we work in "X" units.
07/11/2010 17:16:00
To me, "X" would be derived from any drawing or plan I was working to.
So even if all my machines were imperial but the drawing was metric, I would class myself as working in metric and view the conversion process as being a necessary evil.
Thread: Metric vs Imperial - Practical or Traditional?

I haven't read the whole of this thread, but I think we all need to get DRO's or this discussion will never end.
06/11/2010 08:38:44
I had to smile when I read the post above by ady, which says "...If you got it wrong then your eyes were gouged out..."
and is followed by paul trotter's comment of "Sorry I don't see the problem..."
05/11/2010 22:09:20
I know that, but he obviously made the mistake of putting feet where he meant to put inches.
 A bit like the mistake you've just made

225 inches = 118" - 9" as I said
5715mm does not equal 225 feet as Ian Stated!

Thread: Mistakes in Van Rennes article

Hi David.
Oh, I see. I wasn't having a go at anyone with that comment, as I thought the magazine was employing an extra person to lighten the workload.
I took it from the general drift of the thread, that you had to do it all yourself.
It's a shame about the lack file upload/download facilities - it could be so useful.
Thanks for the clarification.
04/11/2010 13:56:48
Can you tell me why you've edited my post please?
04/11/2010 10:00:25
I am of the opinion that updated, downloadable drawings, should be made available on this site, even if it means making corrections ourselves and re-uploading.
Corrections published sometime later in the magazine are wasteful of valuable space as well as being unlikely to be found in time before construction has begun - putting them here, along with a link in the publication helps to keep things tidy and once the principle is established will become second nature. 
The web is a heaven sent gift for people to collaborate and deserves to be used by us to full advantage.
As more and more people become involved with CNC machining, I see a real need for a File Download area that we can place these drawings and believe attachments should also be enabled when posting to threads such as this.
