|Thread: Tuna Can Blower|
That's a neat dodge, Stew.
Do you know - does anybody know - if it would work with a lip-and-spur drill as commonly used for wood, or are they too soft for metal?
|Thread: Has anyone watched this Girl|
Regrettably, this is the sort of flippant remark my daughter has to put up with both at work and elsewhere, and an attitude that a century and more of women in engineering has failed to shift. For the record, she is a qualified, skilled and experienced practical engineer, and a good cook.
She is also a trained and active semi-professional classical singer, which causes much amazement among her colleagues, many of whom don't exert themselves beyond drink and take-aways.
|Thread: Apologies for raising this again|
Martyn, I can understand what you are trying to achieve, but not why you are trying to achieve it. I'm not familiar with the details of the Austin 7, but I presume the gear ring is normally hidden within the bell-housing and therefore invisible to the naked eye.
If your intention is simply to prevent a mash-up if somebody tries to use the electric starter, wouldn't it make better sense to simply leave the starter motor unconnected? It would be a simple matter to make some sort of insulating bush for one of the connections in the starter circuit, which would be invisible to all but the most determined of observers.
|Thread: Windows 7 support ends|
Yes I did, and it makes perfect sense to me. The day after support ended they rolled up all the outstanding issues into a ball and shot it down the wires to us, meaning that they have dealt with all the known issues, and don't have to concern themselves with any future ones.
|Thread: Only for Myford lathes|
Looks really nice. The only thing I would have done differently would be to have the right hand end of the tray sloped instead of vertical, to make it easier to brush out the last bits of swarf.

|Thread: magic 127 TOOTH ?|
I use the ML7 gear calculator by Duncan Munro, available here: http://metal.duncanamps.com/software.php
It's a very versatile program which can be set up to calculate which gear trains to use from the standard set, or your own set, or from any imagined set. It can also be altered to calculate gear trains for other lathes.
I used it to work out the gear trains for my own collection of Myford gears, transferred the results into a spreadsheet, tidied it up and use that in the workshop. Out of interest I put in a column calculating errors (the original program doesn't do that) and was surprised at how accurate many of the results are. I needn't have bought the 37 and 47 gears after all.
|Thread: The cultural status of engineers in the UK|
In Britain the problem dates back to at least the nineteenth century, when those who had made their fortune in engineering or manufacturing were desperate to join the upper crust, and educated their sons in latin and greek so they would be socially acceptable. This attitude is still at large in our own times, as witness the politician Gove whose 'English Baccalaureate' has done more to to destroy creative education than anything else in the last couple of generations, though goodness knows the other politicians have tried.
The engineering professions have bleated all my life, and all my late father's, about lack of status but have never done anything serious about it, with the result that (to give but one example) the girl who came to wire in my cable TV installation is described as an engineer. I might add that I was delighted to see a female technician, and told her so.
I don't expect to see a change any time soon.
George B, MIET etc.
|Thread: New legislation that could affect us all.|
Hmmm, smacks of etymythology to me, like the explanations of 'sleep tight', 'posh', 'threshold' and many other phrases and sayings we are expected to believe.
I did a search. Is this what you had in mind?
While I can't help with tea making, I do have a three-page document for the weekly Plant Maintenance of the Instrument Maintenance Department bicycles at Fawley Power Station. It boils down to "Check the tyre pressures. Inflate as required".
When I was at Fawley in 1971 a Work Study programme was instituted, where every conceivable task was specified in a Time and Motion sort of way. Without a Work Specification a job didn't exist, so couldn't be done. It was a nightmare! This specification was written by my manager, complete with diagram, and I could never establish just how far his tongue was in his cheek when he wrote it.
Unfortunately I only have a very faint photocopy which won't scan successfully, so I can't put it up for your instruction and enlightenment.
In all my years of using loos, I've never known a woman to have the good manners to put the seat up after she's used it...
|Thread: Myford super 7B Chuck threads|
It's worth being aware that the late ML4 had the same thread as the ML7 but the register diameter was 1⅛ " not 1¼" , so face plates and such exist with the smaller register which would need boring out before fitting to a ML7. I know, I have one on the list of things to do...
Swarf, mostly, thanks for the tip about pinning the character map to the task bar. Done it!
When I bought my ML7 the 3- and 4- jaw chucks that came with it fitted perfectly, but nothing else would go on more than about one turn before jamming. On close examination I found that the mandrel thread was slightly deformed - goodness knows how - and a few minutes spent with a small file cured it.
If your other backplates go on as far as 1½ turns I would conclude that they are the correct pitchbut with a problem of fit. As others have said, a tap may cure it, if the problem is in the female thread. It's worth remembering that chuck threads should be a bit slack, to allow the register (which should be very accurately machined) to align the chuck as it is screwed home. So even if you bung the correct tap through a slightly wrong thread, the result will probably be perfectly satisfactory. You won't strip the thread unless you are really brutal with it.
P.S. If anybody wonders how I got ½ instead of 1/2, the secret (in Windows) is to hold down the Alt key and type 0189 on the number pad. There's a whole world of alternative and useful characters out there!
|Thread: Have you got one?|
That makes more sense!
|Thread: Lucky find|
That would be my guess. The white handle of your pen is likely to be celluloid, bone or ivory, depending on the age and quality of the set. Other pens had ebony handles.
I think your set is more likely to be twentieth century than nineteenth, from the style and finish of the box. On-line pictures show Brunel's set to have been in a polished hardwood box with a lock.
This style of instrument was popular for a very long time, and one of my old engineering books - I can't recall which at the moment - has instructions for making your own.

|Thread: Plumbers Jointing Paste ???|
Hawk White does the same job as Boss White.
|Thread: Dickson detailed dimensions.|
Or in the words of the classic rhyme:
Teach not thy parent's mother to extract
the embryonic juices of an egg by suction;
That worthy lady can herself the feat enact,
quite irresepective of thy kind instruction.
|Thread: Lathe lighting|
I drilled a small hole in the back of the switch when it failed, and squirted some switch cleaner in. It has worked reliably ever since. The hole location was a best guess, not scientifically placed at all.
The Ikea clip-on type has flabby rubber jaws which make it difficult to aim precisely, and it tends to move over time. I find the spread of light is insufficient, so I am planning to replace mine with something which gives less of a beam of light and more of a pool.
By the way, Noah had a treadle-driven ML4 on the ark because he had no electricity. Besides, the ML7 wasn't introduced until after the flood.
|Thread: More evidence that the world has gone mad!|
And of course there's my Uncle Will's motoring joke, probably from the 1920s:
"If Morris put the Ox in Oxford and the Cow in Cowley, who put the 'oss in Austin?"
