Can’t you get a copy from your local library that will save you all that hard earned cash?

I'm not sure how it is in the UK or other countries, but in mine no such books are available at public libraries.

You can ask at the desk in you library to get the book for you. You will probably have to wait a few days. That is what I do When I want a book that they don't have in.

Let me try to explain that again ;-) 

If that is how it works in the UK, it's great and I am happy for you guys. 

But not in my EU country. If a given book is not available, it ends there. Plus books in foreign language or technical subjects are generally not available. 

Anyway at the present time public libraries, as well bookshops are closed due to pandemia. One can still order online. 

This book is currently unavailable from Amazon, but Cousins UK has what is probably a reprint, so I was curious to know if anyone is familiar with it.

Book, What’s a Book:)

A book is a medium for recording information in the form of writing or images, typically composed of many pages bound together and protected by a cover. The technical term for this physical arrangement is codex. :D

I did ask:)

That book does have some good information, and I wouldn't say it's not worth the money. But it's really conceived as a textbook for classroom use, to be a guideline. I find how it's written and presented to be more along the lines of textbooks I saw when I was like 12 years old, apart from some of the trickier math calculations; seriously. I don't own it, but there has almost always been a copy in the workshop that belongs to someone or the other.  I would suggest trying to get a hold of a copy as a loaner, from someone, maybe you'll need to offer a deposit (loaning books is always a tricky affair). Have a look through, and see if it's worth it to you. As an overview, and a way to see down which paths you want to find out more information on.

 

Just grabbed a shot of one of the pages on hairspring work, it's murky enough I think you can see what's going on without infringing any copyright.1113935538_book(Large).thumb.jpg.36040431d2db8abdd382ecc7c48edeaf.jpg

You'll be telling me it is made out of dead trees, or some other nonsense next. :P

I've got a copy as Nickelsilver says its written as a text book for a classroom.

If you want the formula for just about anything in Horology this book has it.

Likewise if you want the theory of how something works its probably in this book.

If you want a book that will teach you how to make a balance staff, replace a cracked jewel or any other 'hands on' technique this is not the book you want.

If you are a hands on type of person I would not recommend this book, if you like to know the underlying theory on why things work than this is the book.

If you have limited money and are looking for books to teach you how to carry out complicated repairs look for Archie Perkins's books.

If you want to know the linear coefficients of expansion of different materials along with the formula to work out the length of a pendulum clock and the effect of temperature on the daily rate so you can make yourself a super efficient clock this is the book for you.

I like both and will take that book off your hands:)

I didn't say I didn't want it. :D

Its not my 'Go to' book, but there are times when its useful, especially when you need a formula to work out something, or you just want a greater understanding how something works to let you figure out why whats in front of you doesn't work.

    • Hello and welcome to the fo4um. Enjoy
    • Welcome to the forum, enjoy.
    • You're asking a pretty broad question and you didn't specify the machine but yes it's simple especially if you have the right machine. The question has problems but I'll take it as it is. Is it really that simple yes especially if you have the right machine. So in the video below he's making a screw and yes it really is that simple but pay attention to the machine it is not simple at all probably wasn't cheap but it is small it will probably fit in your garage. Unfortunately wouldn't fit in my garage as it's far too cluttered up with things. In the video he talks about making a screw and pay attention to the machine. The machine has lots and lots and lots of cutters and lots of things to do lots of machining all-in-one machine conceivably one step after another all programmable. If you look at his channel lots of CNC's stuff and there are several other videos related to this machine. He goes to the factory where they talk about it and show all the other machines they make in Switzerland.  I did look up the specifications the machine I don't recall the price it's not going to cut wheels I think it has a maximum diameter around 11 mm basically it's really good for making small diameter watch parts. Then in one of the other videos he goes to a factory that used to make parts with waterpowered machinery been in business for 100 years and everything they now make is made with CNC machines including this one. What was interesting with the factory photo was that when they make some parts they can put them on a optical comparator comparator compares with whatever the reference is and the machine can be programmed to adjust its cutting to make sure everything is actually being made to specifications. Oh and then somewhere in all of this there was at least one picture of a balance staff can't have a CNC Swiss machine without making balance staffs.   It would be really nice if we had pictures of the machine. Then yes if you look at the page for wheel cutting you can enter parameters and it will generate a G code but he left out things? Notice he has a picture of a complete wheel but the G code isn't making a complete wheel it's only cutting the gear teeth I don't see whereas the program for crossing out the spokes? Typically when you see people cutting gears once the teeth are cut most the time the spokes are cut by hand. Occasionally someone will mill them out but typically not with the program which seems strange if you have CNC capability for instance one of my friends fill it used to design assembly line equipment or things to make things. So his hobby was to continue to make tools to make things like clocks. Very interesting and clever clocks but his true fund was making the machines to make the clocks. Then machine is not controlled by G code like we would typically find today as the stepping motor controller he has was made a long time ago and the individual controllers used a textbased program. So the company had a editor you could write a program to cause each the stepping motors to do something. So basically once you figure out how to cut a gear he would just change the parameters for different size gears so here's an example of a gear as you can see we have the teeth and the spokes. Then we have a picture the machine which sucks because it would've been so much nicer if I could've taken a picture when it was cutting a gears so we can see things better. Then yes there is a worm gear stepping motor indexing this is a mini lathe and the indexing is at the end of the lathe head hiding. The basic operation of this machine would be brass sheet not cut to a specific diameter size not even round mounted on the machine. Then it turns and a milling cutter will cut the diameter. Then the gear would be cut with a gear cutter. The same mill cutter for the diameter although conceivably change the size I don't know but basically the same milling for cutting the outer diameter would be used to cut the spokes. I really can't remember how he did the center hole but whatever it was was very precise.          
    • Yeah I know the site and the creator of it.  the two video clips are good examples of the quicker method and a full tear down.  the quick method will work in many cases. But not always and not for all the different movements.  I strongly suggest to not bend the four tabs as was done in the first clip.  Instead there are three tabs that insert into the top plate, Much saver way as to not break a tab.
    • I found a motor that is 3/4 hp and another that is 1.2hp. They come with speed controller. So I don’t think I would need a wiring diagram. But I sure appreciate you offering your help! Do you think 1.2 hp would be too much for a watchmaker’s lathe?
