FOM. Thanks for pointing me to the book, I've actually got a copy on my book shelves and hah forgotten how much of that kind of info was in it.
There's a lot there! Two more sets- one is that great tome called Machine Tool Reconditioning by Connelly. Bloody expensive, appallingly heavy but you could possibly borrow one from a public library. Your nearest- perhaps is Gateshead! There was a copy there.
Again, you want a copy of Holzapffel. I think that it is a freebie.
As I can't count, here is a third. It is Georg Schlesinger's book on Machine Tool testing.
Newcastle upon Tyne HAD a copy.
Maybe a fourth? Well, why not? Ned Westbury as Editor of Model Engineer wrote as Geometer and I do recall some of his writings still appear about alignments- they were on the net.
However, I think that the result of the obvious examinations should be recorded. As two planes on sliding bits of machine tools wear, have you removed the gib and checked the parallelism or what is left by two cylinders and J Blocks or what you have as substitutes?
One side, that is the side that the gib was fitted should be unmarked but what about the working side? Again, turning to the gib itself- have you miked it for parallelism?
To be sure, there is a lot to do. Maybe there is a time to refresh skills such as blueing and scraping slides.
cheers
