With my current shop, it will be moving from tool to tool. I guess since I'm now going with the Oneida 2hp Gorilla I can run 2 tool at once with a blast gate but it will still be 4" flex hose for the time being until I can figure out how to change out the dust ports on my machines. My planer, jointer, router table and table saw all have 4" dust ports. I can replace the dust port on my jointer and move to a 6" with no issues since it's one of those dust ports that's built into a plate and screwed into the outside of the machine (powermatic jointer). I'm sure I can do the same thing with my router table since I built it myself and can change things out. My table saw and planer on the other hand, I'm not too sure about. The cabinet on my table saw as a 4" cut out to fit a 4" dust port that came with it (sawstop), I don't see how I can change that without putting a 4"-6" adapter on it. Doing that will protrude out too much and will make storing an issue (I think). Same deal with the planer. I haven't really looked into it much yet, but If I can find a quick connect 6"-4" reducer then I may be able to run 6" flex hose from the DC and hook up to 4" dust port. I'll have to stop by my local Rockler store or Woodcraft to see what they have.
Either way I go, it will still be flex hose. My wife would skin me alive if I started running duct work all over the garage, but even if she was okay with it. It's still not an option since my machines are moved out to the middle of the garage during a project and back against the wall when done.
I hope once I can get a dedicated work shop whenever it is we move, I'll be able to still use the Oneida but this time with dedicated permanent duct work. Thoughts?
