I've been pondering something similiar myself - my character wants something similiar [but powered by magic instead of technology perhaps, depends where my GM says golems fall on that line].
By the core rules, the obvious solution is to take a Tradesman [or a couple], with a decient rep investment, give him / them a few assistants, and instead of having his check make silver, have it make items.
If you have a scale 4 workshop, with two professional tradesman, each with a couple of mope assistants, they can roll at +10 to craft stuff, if they take 10, thats 30s per week of adventure, which isn't bad. The other similiar option, is to throw your personal lt in the holding, as a dedicated workshop director, and have him make the craft checks while you adventure.
You're totally right about the Industrial Era messing up creation time for objects, especially with regards to early automation.
