Maybe, but I would wonder how much dust might sneak by because of the threads. They are only partially on the inside, leaving wide gaps. I had considered writing Kreg (I think that is the US contact), to see if I could just buy that plastic piece, then trimming the pieces which form the threads so I have an unobstructed channel, but am more leaning to just making something that actually fits using the threads.
I did see that Triton hose adapter on EBay when I was first looking at the router, but never did get it and haven't seen one since. Peachtree had a bunch of stuff for the Triton that I bought on close out, but the hose adapter wasn't there.
As I was typing this, I thought I might turn a spindle, hand cut the threads, then hollow it.... hmmmm
MayBe when Ed checks it, the Porter Cable piece will work!
