I posted this in response to a Festool tool problem post but realized it should be included in the Jigs & Tool Enhancements board where people may mre easily find it in the future.
Others, including myself, have had problems with the RTS-400, and other sanders, where turning down the CT vacuum to its minimum setting doesn't reduce the vacuum force enough and the sander, for lack of a better term, is subject to "squiggling".
Festool makes a reducer to solve this issue

but unfortunately, it is NAINA.
sae pointed out to me that Bosch makes a vacuum tool end adapter that allows you to adjust the vacuum.

The tool end is a perfect match to Festool tools but the hose end doesn't fit on a Festool hose. What I've done is to create a fitting that allows the Bosch tool end, with the adjustable vacuum, to fit on a Festool 27mm hose
I bought a 1 1/2" x 6" plastic, drain extension from my local hardware store. I cut off the wide threaded section and most of the long, narrow extension tube. The narrow extension tube is just the right diameter to insert a Festool, 27mm hose end into. However, the wider portion of the drain extension is a little to narrow to fit tightly into the Bosch adapter. So, using a trick from Oneida, I wrapped the tube with metalic tape (same kind of stuff Oneida used on their UDD before they changed to conductive plastic) to increase the diameter. I also put some strips of the same metalic tape on the inside of the drain extension that were long enough to overlay the wrapping I was doing on the outside. This assures a fully conductive path from the Bosch adapter to the Festool hose. I've attached a series of pictures below.
