Thanks all, for the input. Looks like I've got a Saturday morning project. Is the baffle spacing on all stock BA pipes the same (except for the tips)? Reason I ask, is the second baffle plate is about 10" from the end. I had a heck of a time clearing out the first plate. Even if the second is easier to punch out, I'd still need a drill bit in excess of 12" just to reach beyond plate #2. Can't find that at the local hardware.
