Built my self a dust shoe over the weekend as I am at last fed up with holding the hose next to the work. I wanted one that 'floated' so that its height was not governed by the spindle. Mark 1 used screws to guide it and was a failure. So I decided to use bearings. These are inline skate bearings from another project. The brush is from a letter box draught excluder.
I have a video which shows that it works really well.

Still cannot get the touch plate to work!!!

The sign at the end is my first attempt at something a little more complicated.
