Thread: Evolution of a 4 Tool Turret |
06/10/2019 16:47:15 |
Graham Meek: Many thanks for the explanation - no doubt I was a little dense to begin with! Is "manual control" still available for intermediate settings? My turret is normally loaded with four indexable holders and intermediate positions are not normally needed unless the topslide is set round. Rod Renshaw: I understand that "urge" is part of the standard vocabulary of technical writers. |

Interesting to me as I am a long-term, happy user of a GHT turret. I admit that, having read this post and turned up GHT's description, I am not sure about the difference between "self-indexing" and the GHT "simple ratchet" design. Is it simply that with self-indexing moving the locking lever moves the turret as well? I would certainly welcome a write-up of the adaptation. |

As a special treat for subscribers, I have created an article around David Lammas' article from 1995, as previously republished in the 25 Years Special, which is now long out of print. www.model-engineer.co.uk/news/article/three-way-toolpost-by-david-lammas Note this is subscriber-only content, so you will need to have a valid subscriber number for ME or MEW to view it. Neil Neil Thanks for reviving this. One of your captions made me wonder whether you have started using Dragon Dictate: "This version is loaded with asset of tools for right hand cutting" |
Thread: Turning between centres on Super 7 |

I think this may be an hydraulic version but it shows a decent turning cut. They are quite expensive for a commercial item but a shop made version could be made. Mike Pursuing my "sprung" query, it seems from the YouTube comments that this one is not spring-loaded. No doubt the significant heat generated is dissipated in the chips/sparks! |

The chisels are spring loaded and do mark the end face where they bite into the job, sometimes you see the little marks left on the end of a component. They are often used for grinding but they are also used for turning. There are videos on YouTube. Mike Is the centre also sprung so as to take care of the work expanding? And is there a hobby market for these commercial devices? |

An additional supplier link: solenttools.co.uk They recently supplied a pair of brushes for my old Wolf Grinderette angle grinder. This machine is over forty years old and I was impressed to find that they were able to supply against the type number of the machine. They also undertake to make brushes. |

There could still be a problem with the space needed to get a pukka translation gear of 127 teeth in place on the leadscrew, it is only a shade under 6.5 inches in diameter. Brian. Martin Cleeve got round this problem by using a 127 of 30DP: see page 44 of WPS3. |
Thread: Perfecto 3-1/2" x 16" lathe half nut lever operation |
30/09/2019 10:59:57 |
A detent would seem to imply a fixed position of the engaged halfnuts ie no adjustment. Later Myfords have a limit screw to prevent overtight adjustment. |

Yes as a retired blacksmith I once had a long discussion with a black gentleman as why I wasn't a whitesmith! Whitesmiths work with"white" metals, eg, tin, zinc, pewter. and lead. Was he from Rhodesia, by chance? |

Interesting point re auto-update; can you give chapter and verse?
I never let Windows Update do its thing automatically. I check what each update is going to do to my system and then decide whether to install it (very interesting sometimes and not just in this context). On at least two occasions this year, a so called "important update" (used to be called "critical" .... important to whom?) when checked, amounted to an auto update to Windows-10. Same thing has happened at least once on my Windows-8 installation. Some related info here. Thanks for the interesting linked article. I couldn't see any dates in this and wonder if it applied only during the period that a free Win 10 upgrade was available; this has now ended but an upgrade is apparently still possible (for those that want it) via the media creation site that I mentioned. MS would obviously like all Windows installations to be Win 10. |

Vanishingly unlikely that support for Windows 10 is ending ....it's the current Windows version.
Support for Windows 7 is ending however. If you indiscriminately install all the "Important" updates for Windows-7, that copy will be auto-updated to Windows 10 at some point. Edited By Bandersnatch on 28/09/2019 22:51:54 Interesting point re auto-update; can you give chapter and verse? Did I waste my time in upgrading to Win 10 via the Microsoft "create media" site?

How about referring a suitable tap or taps to the spindle thread? With everything clean and a light behind it should be possible to ascertain the angle. |

Long nose pliers or a ‘dremel’ or small awl can all help with starting the pins, at times, when the usual kit is not to be easily found. Oddly enough, you can also use a comb or paper. |

It's such a shame that they do not manufacture an easy-to-read rule as they used to. Personally, I find the 1/2mm markings quite a distraction too. Pete According to their catalogue these "Saw-Tooth Graduations" were "specially introduced for easy reading by students and apprentices". |

Panel pins can be rather awkward with a large hammer!
Get a pin push? I've got a plug in one of those Nice! I have an el cheapo Tacwise nail gun which is surprisingly good at the price; bought to fix glazing bead round expensive DG units which I didn't want to approach with a hammer. The old school pin push is really only useful for starting the pin. |
