The draw bar swings away on its pivot mount so you can simply un-thread the TTS collet and replace it with a standard R8 tool. No need to remove anything but the TTS collet from the bottom of the spindle. You can then just thread it on and pivot the draw bar back. Of course the draw bar won't do anything with that tool, but the change over from TTS to standard and back is an easy operation. Leave everything in place.
