Hi K2, I agree even if I started it with a simple query. I pray that I've finished it and left the thread back to John and his discussion, but I love the study of language as well as engineering o_O . Hi Terry, I find this "curious" - and have been looking at the diagram. I can only surmise...

You are confusing language and vocabulary, the bulk of words in English are of ancient origin even words to describe new technologies such as televison or photogaph are concatenations of more ancient words. 'Language' is a comination of grammar, structure and vocabulary. Words can accepted...

Hi Bill, I generally agree with that sentiment but there are occasions,when the bulk of the body of a live centre gets in the way, especially when using a QC toolpost such as the Dixson type and needing to machine at the tailstock end of the work, then a dead centre is needed, or even a half...

Hi VicHobbyGuy, You are confusing language with vocabulary. I admit that I can't speak Anglo Saxon (although most of what you write is actually reasonably understandable with out consulting a translator as long as you know the symbols such as the thorn derived from a rune of the Elder Futhark...

As a liberal white British European I have never used the 'n' word you are implying in your typical comment. And I will never reference the ugly, snotty term you prefer to be identified by. An example of nominative determinism if ever I saw one. I prefer to use real words not made up ones by...

Yes, I must admit that tyro is not widely used but that's because it's not widely used, especially by lazy folk. But 'noob' does sound like something emanating from someone's nasal cavity. I find it interesting that 'newbie' bcame 'noobie', then 'noob', so logically it next becomes 'noo', then...

Hi K2, This is from the Southbend 1934 manual, The cutter should be positioned on a line 5° from and above the centre of the workpiece, it's also the recommendation of Boxford: Regards TerryD

Hi John, The Latin spelling is tiro and refers, in Roman times, to a novice soldier. by the way I sent you a message, I need an email address for you send it via converrsations for privacy TerryD

You're probably right John, My centres are all 2MT and I use a 2 to 4MT adapter to mount ones in the spindle Regards TerryD

So ugly and inelegant, like many US made up words like 'pled' instead of pleaded, 'dove' instead of dived,' snuck' instead of sneaked etc Ugh. if you fixed a faucet that leaks I think you'd say "it leaked" not "it luck". There are perfectly good words used for many many years in English...

Hi John, Here's one of the blanks suitable for a fixed steady I got from my local engineering company this one is about 190mm dia. as you can see. As one of my reverse jaws for my 3 jaw chuck was lost in a workshop fire I'll have to bore out in a 4 jaw chuck to the required diameter and then...

Hi Will, When I started my apprenticeship we used tallow, solid fat but low melting point and excellent lubrication, but horrible stink😖 In fact as the stink got worse it was an indication of overheating😤 and time to stop. TerryD

Hi John, It's bad practice to part off with the outer end supported like that. It is possible to cause all sorts of mash ups and can be dangerous if the work piches the parting off tool as it's nearing the end of the cut.. Parting from the front normally is not to bad as long as the work is...

Can anyone explain why we use uneccessary construct 'Newbie' (or even uglier - Noobie) when there is a perfectly good, shorter to type, more elegant word - Tyro (m. Novice)- from the Latin, so in use for over 1000 years and in English for at least 500 and in use certainly in the USA 😉😉 Best...

Hi John, Dalboy, Just for your information, after my last post I came across this in the same Southbend 1934 Manual regarding centres: Not sure if the ' "...groove around..." is still relevant here in the UK at least, I must check mine 😣 but the comment about the "...always hardened..."...

Hi John, The original machine suppliers (Chester?) will be able to provide extras such as live centres. Remember there are 2 types of dead centre. Hardened ones which are intended for the tailstock and 'soft'(unhardened) ones intended for use in the lathe spindle you can test this with a...

Hi john, Try 'Noggin Ends' (click link), they used to based in the West midlands not far from where I was born, but are now in Stoke- on- Trent. For future refernce they have stalls at most major exhibition for purchase or collection of online orders. Macc Models in Macclesfield is also a good...

Hi K2, The 'roughing' tool on the diagram (Middle row LH end) you linked to is my preferred basic shape and I use it for most of my turning as well as the LH cutting tool of the same profile for LH turning (which I rarely need to do. I find that geometry very robust. I even use the tool for...

Hi John, The 'grooves' on the top of the HSS tools are there to provide a 'rake angle' which varies according to the material being cut. for example the proper top rake for Brass is zero while for free cutting mild steel it would be around 7° (I admit that I also use these to cut brass)...
