I recently bought my first Festool tools (CT36 and one of the sanders). The impetus behind this was my old shop-vac dying. It is a smaller shop vac that uses the 1 1/4" tools. I like the CT36, and I'd like to grab one of the sets with the D36 hose and some attachments, but I really don't want to drop the money on it right now, so I'm trying to find an adapter that will go on the tool end of the D27 hose and then allow me to use the attachments I have. My first guess is the stepped adapter that you see at a lot of places (link), but I don't know if the end of the D27 hose will actually go into this and hold. Anyone know if it does?
