Thread: Wouldn't it be nice
02/04/2016 18:12:47

I don't think anyone mentioned the possibility of using a ball bearing nut to help in closing.

Would the imperial sizes help?

Tim Stevens:

I clearly need to update my statement! That use of the word is entirely new to me and not even mentioned in my OED - as the RD would say "It pays to increase your word power" but I agree it can also take up valuable brain space.

Thread: Low speed grinder or standard for lathe tools?
30/03/2016 12:47:25

I am no expert but the wheel manufacturer will know the correct peripheral speed for his product ie the speed at which it cuts most effectively and therefore does not tempt the user to press too hard.

The slow speed (dry) grinders are marketed as suitable for woodturners.

Thread: Total loss oiling?
30/03/2016 12:42:42

Many years ago S U Belsey contributed an article to ME describing how he captured and re-used the bulk of the oil from his ML7 headstock - the first and last time I have seen the word "tundish" in print.

alex costea:

Welcome. Can you tell us a little about the Indian machine tool industry?

Thread: Is this a ML7?

Wout Moerman:

Thanks for the explanation - franken as in frankenstein, no doubt! I think we might call this a mixed marriage but I like franken more.

Whilst I can't answer your question with complete confidence you might find the lathes.co.uk page on Myford clones to be of interest.

IP ownership: presumably there is an EULA and it would be open to the company to include a licence by you to them. Have you read the small print?

Wout Moerman:

Is frankenlathe a recognized make or, perhaps, Dutch for hybrid or similar?

Dutch cookies look tasty!

Michael Gilligan:

Many thanks for this fascinating link which I have skimmed and bookmarked for later perusal. The little I know about Maudslay makes me think that, in his own way, he was a genius - how tragic that his life was untimely ended!

martyn nutland:

Did you consider Arnold Throp's excellent little book which is WPS2?

Thread: Unknown lathe on Ebay

Roderick Jenkins:

I wouldn't know about Gumtree's reputation for accuracy but many of the descriptions on eBay are absurd and often accompanied by a "disclaimer" to the effect that the vendor knows nothing about the item they are selling.

Roe (the book I mentioned above) says that W F & John Barnes were established in Rockford, Illinois in 1872 but did not begin making lathes until some years after so 1820 certainly seems to be wrong.

Fair comment by you. If the 1797 Maudslay was the invention of the screwcutting lathe then, by definition, it was ahead of its time generally.

Michael Gilligan:

Thanks for the Maudslay link; I see that there is a wealth of related material on the site concerned. Interesting in the light of Michael Walters' comment about the form of slides that Maudslay's early lathes had prismatic beds. So far as I know, these were made the hard way ie by hand with hammer, chisel, file and scraper.

Extract from English & American Tool Builders by J W Roe 1916:

Take the slide-rest. It is clearly shown in the French
encyclopedia of 1772, see Fig. 3, and even in an edition
of 1717. Bramah, Bentham and Brunel, in England, and
Sylvanus Brown, in America, are all said to have
invented it. David Wilkinson, of Pawtucket, R. I., was
granted a patent for it in 1798. But the invention has
been, and will always be, credited to Henry Maudslay, of
London. It is right that it should be, for he first designed
and built it properly, developed its possibilities, and
made it generally useful. The modern slide-rest is a
lineal descendant from his.

PS Maudslay's famous screwcutting lathe of c 1797 had a screw-operated cross slide but, seemingly, no top slide.

Thread: Models stolen, Lancashire
10/03/2016 16:16:56

I learned of a theft from a different kind of garage today (my local MOT/service station). The thieves had removed an 8 foot long window to get in and made off with a heavy safe by the same route. The other item stolen was the plug-in reader for today's computer controlled vehicles.

The tailstock at least looks shop-made.

I think Michael Gilligan's blow-up does indeed show that they are not angular contact bearings. I can now see the labyrinths but I am not clear as to how the pre-load is applied.

Thread: Myford super 7 cross slide and oil gun
08/03/2016 18:02:47

If yours is the model 300-1 Wanner then it is probably the best of a bad bunch. Mine works better with an O ring slipped on to the nipple before use.

Tim Stevens is spot on with his comment: there is no known way of preventing folk from pumping grease into oilways.

Some have fitted hydraulic nipples but then you need to find a suitable oil gun to work with them. I agree oil cups could be fitted in most cases but they would tend to catch on the cleaning rag.

The washer can be given more dish with a tap from a soft hammer.

In truth I didn't, but thanks for reminding me of this useful feature.
