Gang,
Recently the DC on my K3 went from OK to terrible. I opened up the saw and discovered the 4" internal hose from the blade shroud had gaping holes in it from where little crosscuts had been launched into the sidewalls. I really need to get a ZCI but that is another thread.
I have a full 5" hose headed to the back of the machine from a 6" PVC drop down, but I'm curious if anyone has replaced the 4" internal hose with a larger 5 or 6" hose. I have already removed the back plate and the dust port from the cabinet to take out the old hose. But the 5" hose will not at all fit through the hole in the cabinet of the original dust port. For a quick experiment I ran the 5" hose straight to the shroud in the back of the cabinet through the giant access panel in the back. Collection seems to be much much better.
Has anyone swapped out the internal DC hose and if so how/did you enlarge the DC port in the back or did you knock a new hole in the back access plate?
