File this under other politics. I suspect the real starting point for measuring the war potential of the northern region against the 11 states that eventually joined the Confederacy was 1856, the last year before the 1857 financial panic in the paid labor states.
The St. Louis Fed Res produced a time series on how much railroad building slowed in the mid decade of the 1850s.

At the time, I think most people in the northern states knew ship building was slowing down in the 1850s as the Gold Rush cooled off and Aspinall's Panama railroad took a good deal of revenue from the steamers cruising around the horn of South America. More ships were not needed and British ship building was picking up.
The Preliminary Report of the 1860 census recorded the numbers with respect to ship building for the decade. I think Lincoln and Sec'y of the Navy Wells knew the US had plenty of ships and that losses to the Confederacy were of the same order of magnitude as losses to storms and decay.
The paid labor economy of the US was involved in a dynamic process of industrialization fueled in part by foreign immigration and British investment. The US was a net debtor nation for most of the 19th century.
Commissioner Walker's 1870 census more closely reflected the breadth and scale of US industry especially with the numerous applications of steam power to manufacturing and transportation.
If this view is correct it goes a long way to explain why the US Civil War ended in total victory for the federal forces. The best metaphor for the US military/industrial complex was a train gathering speed on a descending grade. It may also explain why the ordinary man in the deep south had no idea what he was going to be fighting against. That would contrast to the cities and counties bordering the paid labor regions, as the people there had much more opportunity to visit the northern cities and see the goods available from northern merchants.
Table 15 reflects the ability of the mechanical revolution in the northern areas:

It seems to me that a nation capable of mechanizing the process of stitching together garments and making seams and button holes, might also be able to produce some new and effective weapons of war.
