Hi Vince, all...


The old sense of the word 'throw', so far as any use I ever heard, was not a
corallary for 'turning', but rather, a reference for how far, or that,
something reaches.

Throw, in reciprocating Engines, is necessarily, the distance of the Piston
travel, or, of the offset from center, of the Crankshaft section which holds
the connecting Rod; the 'throws' of the Crankshaft are those areas to which
the connecting rod or rods, attatch...and their offset from center is their
'throw'.


This is the true use of the old sense of the term as far as I know...not to
mean 'Turning', but to mean or refer to, how far something reaches whether
or not it rotates to do so, or, reciprocates in some way, or just does
something once.

Hand Pumps Handles, have their 'throw', and it is the distance they can, or
must, travel to actuate the interior means of pumping. O9ts of things have
their 'Throw' in some way, and the term is often one which identifies some
important capacity or scale.

When you throw something, it is not turning it...when you throw a Stone, it
is not 'turning' it per-se, even if it may rotate in the Air while
travelling...

Throw, when applied to attributes or propertys of mechanical or
reciprocating things, is the distance some part of that reciprocating thing
moves.


Turning, is something else entirely. Turning is rotating, not reciprocal or
distance-motion of something liniar.

Throw, would seem more nearly a paralell to the term 'Cast', than anything
to Turning...

It does seem, that the present members of what had lastly been the British
Empire, mostly use the term 'Turning' for our term of Trimming.

I do not think they call Throwing, 'turning', do they?

Wood Turning is 'Turning'...

Never and not, 'Wood Throwing'...


But there is Wood 'chucking' as we may recall...

And "How much wood would a Woodchuck chuck, if a Woodchuck could chuck
Wood?" and so on...remains an open question...


Love,


Phil

"Turning" pottery on a lathe is still done, I believe, in some British
factory potteries, where a slip-moulded piece is first turned on a lathe to
finish the form, and then fettled as well (why this would be needed after
the turning, I'm not sure), according to the text on the website I saw this
on (I forget which, but have it somewhere, perhaps, and when I find it, will
post the url.)

Hi Ric,

Yes, I know that fettling is the trimming of the edge of a moulded piece
where the parts of the mould meet.

But my point was more complex, I think. In the Cobridge Pottery website,
the pottery goes through an extra stage. Here is the list of procedures up
until the glazing and before the decorating of the stoneware made at the
pottery:
http://www.cobridgestoneware.com/CGI-BIN/tourproduct001.asp
> Cobridge Stoneware Pottery processes (before glazing and decorating):

> 7. The vase is turned on a lathe.
> 8. The vase is fettled, and sponged to ensure a smooth finish.

So my question again is, why, if the vase is turned on a pottery lathe after
being removed from the mould, will it not already have lost its "messy"
mould lines? Why does it still need to be fettled?

My only thought is that the turning is limited to certain parts of the
piece, for refining a shape, rather than an all-over turning, which would
certainly remove the mould lines...

Here's another page which mentions turning and then fettling, in this case
after already having handthrown the piece:

Nothing spontaneous about the work made in these two production potteries.
Well, that's the nature of production potteries, I suppose, unless they are
very small houses consciously specializing in a looser look. IMO

Helen,


Could be a loose use of the word LATHE ?  Maybe...More like a banding wheel, or turntable that is used to smooth the round area accessible by that method and then fettled further in the nooks and recesses ...and then sponged?


Who wrote the description? A potter or an observer?


Regards,


Ric
