When I run my 4x6 bandsaw there is a distinct moment on each rotation
of the blade where there's a "whump" sound and the saw bounces
slightly.
I have a Horror Fright 4x6 bandsaw that does the same thing. On mine,
both pulleys have significant runout. Switching to a Starrett blade
helped, but I suspect that correcting the runout is the real solution.
