The F and E lightning was a very heavily built saw. considered by those who have one as at least as good if not better than Tanny and almost as heavy as Yates. I would guess the rpm is correct. 600 rpm less slip would be about correct for a direct drive 36" machine. Still over 5400 SFM. Condition is everything although there isn't much to a bandsaw. Make sure the wheel spindles are not worn and track true. Dave
