But... you still tillered it with a rasp and scraper by hand. If it only took an hour, good on you. It just means you're getting better.
It often doesn't take me more than an hour or two to tiller a bow, but that is certainly not the amount of total time it takes to make a bow from start to finish. I find I spend WAY more time finishing bows than tillering them. For me, the actual tillering is probably the least amount of actual continuous work. That would depend on the stave, of course. A challenging character stave would obviously take more time, but I can pound out a backed board bow in very little time.
With experience, you can dimension your staves to require minimal actual hand tillering. That was the one single thing that sped up my bow making. BUT... you still have to teach that wood to bend, and that requires patience and knowing what to do when.
