|Thread: HSS or CS taps and dies|
Adrian, my go-to taps are Presto HSS
I would be interested to know what taps (i.e. brand/range) Andrew prefers and who the "professional tool suppliers" are he buys them from.
|Thread: A Unique Word?|
Always were, Neil; specifically apex predators of the ursine variety, namely forebears.

Yes, I suppose this is inevitable as we get more and more used to seeing a newly compounded word. I wonder whether anyone writes "girl-friend" any more? Or "to-day" or "cup-board"?
One bugbear (or is that bug-bear?) of mine is the word "predate". Having read widely in ecology in my youth I got very used to understanding the word "predate" to mean to "prey on". "Pre-date" was the other word. Now, they're both "predate". A useful disambiguation has been squandered.

|Thread: Presumably this is done using CNC... but even so its impressive|
I'm not quite sure what you mean by "source", Michael, but the four character company name cut into the side of the piece is 北京精雕 (Beijing Jingdiao), which just translates as "Beijing fine engraving". Their website is here, and they have an English version too.

|Thread: Notre Dame|
Your comments may or may not be correct if you're talking about state aid. However, in 2017 alone British people as individuals (i.e. people like you and me) gave £10.3 billion in private charitable donations. https://www.cafonline.org/docs/default-source/about-us-publications/caf-uk-giving-2018-report.pdf
Perhaps you'd be good enough to acknowledge therefore that, contrary to your rather too sweeping assertion, the UK in the form of many ordinary British people does in fact give substantial amounts of money "to help the starving" and with no "strings attached".

Duncan, a little reassurance that you've not (inexplicably) included me in the category of miserable buggers/whingers would be welcome at this point. It's a fairly drastic misinterpretation of my position if you have.
That's a completely understandable response, Gas_mantle.
Your thinking was anticipated by a few thousand years by Aristotle, who in discussing moral virtues in Book III of his Nicomachean Ethics deals with the virtue of "Liberality/generosity" in the section immediately before the one on "Magnificence"; by magnificence he had in mind such things as lavish spending on public projects such as temples.
Incidentally, one thing I've not seen mentioned anywhere in the news is the beautiful and diverse range of trees that were growing on the site and what damage these trees have sustained.
I could give you a long disquisition on various needs and yearnings that make us human, but Francis Thompson summed it up more eloquently in his sonnet "O nothing in this corporal earth of man...", particularly in the closing lines:
"...Our towns are copied fragments from our breast,
And all man's Babylons strive but to impart
The grandeurs of his Babylonian heart."
Notre Dame is one such Babylon.
|Thread: Impressive Workshop in Germany|
It's rare that people of Theo's age (23?) with such impressive workshops and skills have achieved what they have without considerable parental involvement. It does look as if this is the case here too: https://forum.zerspanungsbude.net/viewtopic.php?t=14103
I say this not to detract from Theo's achievements but in order to put them in context, mainly for people like myself who had little or no parental guidance in any of the practical activities they chose to undertake in their youth.
People in my position can easily be demoralised by seeing such a young person with such a well equipped workshop and such an array of practical skills at his fingertips. However, learning how he got there at that age (i.e. thanks in no small part to parental involvement) goes a long way towards explaining why you didn't, and exonerating you (with your sense of self-worth intact, or maybe even heightened) for not having done so.
|Thread: Folding Bike design & build|
Very interested to see this, Alan. It looks very appealing.
I'd echo Roderick in liking to know what gearing it has.
|Thread: What Did You Do Today 2019|
Jim, I've been using Stihl strimmer line for the last 38 years, and never had a problem with it even when used with my relatively powerful Stihl KM130 brush cutter. I've never had to keep it moist or resort to any other method to reduce brittleness, because it really isn't brittle unless I make the mistake of trying to cut excessively tough material with it such as thick brambles, which, as the manufacturer advises, I would normally use a (Stihl) metal blade to cut.
Just make sure you buy the right diameter line for whatever cutting head you're using. I use 2.4mm cord (orange coloured) but you may need a thinner one. Your manual should say.
|Thread: What new lathe?|
The Colchester looks wonderful, David.
My initial thought was "he's got that nice Boxford and a Myford already. Why does he need the Colchester as well?"
And then I realised it was just my jealousy talking, and I might do exactly the same as you if I had the chance/space/funds.
Which is still jealousy talking, but amicable jealousy at least.
|Thread: How Are Letter / Hallmark Punches Made?|
Dave, did you ever see this thread, particularly my post about punch cutting?
Brass and steel moveable type and decorative motifs for the printing and binding industry are still made (or were until last year) by deep relief engraving on pantograph machines. CNC machines are the more up-to-date method, but cost prohibitive perhaps for most home workshops. Files and gravers are the cheapest method, assuming you can make the time to develop the skill required to use them to good effect.
|Thread: Soba rotary table|
I'd say it's legitimately pejorative when chasing microns means aiming for a level of precision that is considerably in excess of what is required for the satisfactory functioning, or satisfactory appearance, of the item being made.
On the other hand, though speaking pejoratively in these circumstances has reason on its side, it fails to take account of the potentially high levels of satisfaction experienced by some people when they aim for and achieve a higher level of precision than is strictly necessary for reasons of form or function; achieving such satisfaction might be rightly considered an end in itself.
And then there are circumstances, which perhaps few home machinists meet with in real life, in which very high levels of precision definitely are called for and to achieve which you may well have no alternative but to chase microns.
I'd say the generalisation is justified, Vic.
The manufacturing environment in the two regions is fundamentally different. Probably the most elusive yet important factor is the political situation in each region, and the degree to which this allows fair competition (healthy for innovation and quality assurance) in private enterprise to prevail.
Going back to Soba, I've got a three inch rotary table of theirs that I bought ten years ago, and it's been fine for what I've wanted to do with it. Maybe Soba's manufacturing standards were better ten years ago or maybe I'm just not a sophisticated enough user (yet) to have discovered its limitations..
|Thread: Brazing after milling whilst preserving accuracy|
Many thanks for your contribution, Nick.
One detail I didn't explicitly mention is that my current milling machine, a Proxxon MF70, accepts cutters with a shank diameter up to a maximum of 1/8", so I don't know that any woodruff cutter properly speaking would actually fit in my spindle.
Also, I'm not absolutely sure I've understood what you've proposed, but wouldn't passing the woodruff cutter along the channel when laid flat on the table produce radiused inner corners? Avoiding these was the main reason I wanted to be able to stand the channel upright for milling.
Thanks, David and Jason, for your comments.
David, yes, electrically heated typeholders are not unknown, but have always experienced a poor uptake among the binding fraternity. Factors against them are:
I've now completed this project. I ended up hand-filing the long edge flat. I'd have liked to be able to make knurled thumb screws, not use bought ones of the kind pictured, but I've no metal lathe to knurl with (or do anything else with) at present.
The tool handle is made from a Magnolia that I planted 22 years ago and lopped some branches off last year.
Perhaps the newest aspect of the project for me was hardening and tempering the spring steel (sold annealed). My technique seems to have worked in producing the desired elasticity, but I'm slightly unsure what the optimum tempering method is for spring steel, i.e. what colour to look for in the steel. Some say straw coloured; some say blue. I veered towards blue without managing to retain it exactly in the finished look.
Thanks again for everyone's advice.
|Thread: Neil's Irrelevant Press Release Thread|
Cemented and galvanized. Good to know.
I've fond memories of travelling in my mother's corrosion-prone Mini in the early 70s and being able to see the tarmac whizzing past through a hole in the passenger footwell. Yeah, Minis were cool.
|Thread: What Did You Do Today 2019|
Martin, in spite of your frustrations, I'm very impressed with your restoration work. I hope the press goes to a deserving home.
For the record, these sorts of presses were originally marketed as copy presses for document duplication, not as bookbinding presses, though many ended up being used as binding presses, particularly the ones with generous (i.e. above about 3.5 inches) "daylight" between the platens.
In the pic is one of two dedicated bookbinding presses (known as nipping presses) I own. Its platens are 21" x 15" and daylight is 15". I've also got four copy presses dotted around the house.
