And I wish he would have told me before I started my external usb amiga
floppy drive controller a couple years ago. :)

While I haven't dug into the past posts to see what exactly you are
doing, I use a Parallax uC for my solution to create .ADF (amiga
emulator files) from amiga formatted disks w/ a standard pc drive.

My blog has considerable detail (although spread out) about how I go
about syncing to the data stream -- first at the
bit-level(pulses/transitions) and then at the byte level(to the sync word)
I'd encourage you to check my blog --- everything is ad-free and open
