Re: I'm starting out.. need some help plz
Although I agree completely that, “The Modern Clock is a valuable reference, a reader today has the advantage of more information being available than what existed in 1905.
A few specifics come to mind.
I wouldn’t recommend filling a regulator case with hydrogen gas even though Goodrich gives advice as to where to find instructions to make the hydrogen.
At least when he admits, “The practical details of filling a clock case with hydrogen gas I have not yet worked out” he also says, “No burning light or electric spark must be put into the case while filling, because the mixture of hydrogen with air is very explosive when ignited.”
In 1905 the Hidenburg disaster was still decades away so the thought of having a bomb hanging on the wall disguised as a regulator probably wasn’t on anyone’s mind.
Another safety detail to consider is the advice on mixing the chemicals to silver a dial. I don’t believe it’s a good idea to dilute the solution until, “no trace of salt or acid can be perceived by the taste”.
In 1905 these ideas/actions were understandable and illustrate a fairly common innocence, about various dangers, that exists until things have been tried/tested, usually over time. I’m reminded of my Dad telling me that, to do his own case hardening, he used to but cyanide eggs at the drugstore.
The only outright mistake I ever found in The Modern Clock was when I followed Goodrich’s instructions to lay out the pinwheel escapement on my prototype regulator. For those interested, I describe this mistake here in post #8:
I am bringing this up again because Goodrich makes the same mistake with the layout of the Graham deadbeat escapement. Following his advice results in half the pendulum swing than what is claimed.
To quote myself from the above page:
“Let me make something clear here. I still highly recommend ‘The Modern Clock” for it’s wealth of information. It just shows that we all make mistakes and advice should be considered a guide, not the last word.”
