i would probably make about 2 or 3 batches, sure the US market may only hold 4 per year but you have to consider that the 8640 was sold worldwide plus its not really like im running a business where i have to make a sale or profit.
i also think that probably some owners would take 2 sets just to be on the safe side

initial setup takes about 45-60minutes you are right on that, this is a one time operation, then put a stack of
blanks on and hob them, change the stack and hob the next batch, the time to change the batch is about 5minutes tops,
so lets do the math:
10minutes hobbing time per batch + 5minutes changing time per batch = 15minutes per batch 60/15 = 4batches per hour
* 5gears in a batch = 20gears per hour
2hrs/20gears/hr=6minutes per gear if you machine 1 batch 3hrs/40gear/hr=4.5minutes per gear if you make 2 batches
and so on
Yes, as I said there is some economy of scale, but how many gears
of one type are you planning to make? Ten would probably be more
than you could sell in a year.
