Works for me. Running a game like this can be rough in any circumstances and you're providing free content. Take all the time you need.
A suggestion about resource types if you're still working that out:
Lumber: abstraction of common useful woods
Metals: things like iron, copper, bronze, steel, and aluminum. Considering that the industrialization of aluminum production only really got effecient in like 1888, you might want to consider it a separate resource.
Oils: a general common chemical resource, from what we pipe out of the ground to manufactured chemicals. Can include coal and other fuels.
Cloth: the not chemically made textiles end of things people wear and the soft things made from it.
Other: things that simply can only be obtained through importing the require resources and therefore the question is accessibility and monetary funds, not do we have this in our territory. Could be represented through sources of wealth, access to trade partners, willingness to trade intellectual properties, etc.
If purchasing designs from other countries becomes a thing, we could buy a train or train designs to help on the logistical side of things. According to Wikipedia, steam powered trains have been around since the 1820s, so it's more of a question of finding a train we like than inventing one. Or we could use the steam engine in our ships as a basis for our trains if we do decide to design our own.
So it turns out the timeline wise, we're right on track for the invention of
the moon clip for our Revolving Rifles. So that is something we could have several engineers work on to make our reloading significantly faster. The design has something called "chargers" listed as something that is involved that for the life of me I cannot find on google. It might be this already.
