Hubert,
I remember as an apprentice at Walter Somers Ltd being given a plate =
about
six inches square to scrape flat. The piece I had been given wasn't too =
bad
and when I'd done it the trainer must have seen the smug look on my face
cause he then took a hammer and bruised the surface with the comment, =
'Now
get that flat'.
All part of life's rich tapestry.
Regards IP.

AL - this sounds like a simple and fail-safe idea!
It will be interesting to find out where Nicholson make their files. =

the end of the War, they published a booklet called 'File Filosophy', =

was a mine of information. I think that I still have the copy!
I was thinking of your comments about chipping, and this lead me to =

the heroic amount of scraping done on machines, prior to the advent of =

surface grinders. I spent some time at the Linotype Factory (near=20
Manchester) in 1951, and actually assembled parts of these typesetting=20

They also made flat-bed, two-revolution letterpress printing machines=20
(Miehles, originally designed in Chicago), up to a maximum paper size of =
40" x 60".
This meant that a huge flat cast-iron bed, bigger than the paper size, =

64 pages of heavy type metal, and reciprocated the whole caboodle at =
about=20
2,000 sheets per hour. Four pistons (two at each end) cushioned the =

rollers,
which in turn ran on about six supporting tracks. All of this had to =

scraped by hand - weeks of work! The colossal straight-edges were =

onto the work by crane! They made their own castings and these were =

outside in the rain (this was, after all, Manchester!) for several =
months=20
before machining on huge planing machines. This 'weathering' allowed =

the
design and then wait months to make a prototype! With the advent of=20
photo-typesetting, early computers and offset litho, both the Linotypes =

the Miehles were dead and buried within 20 years.
I must stop muttering in my non-existent beard!
Cheers! Hubert
