    Check out this video.

    Apart from being quite interesting, it shows, at about 5min 30secs into the video, an interesting dust shoe attachment. I like the way it swivels into, and out of, position.
    It is something I'll keep in mind when I make my new one. :thumbsup:
    See what you think. :rolleyes:

    It's basically a pipe clamp holding the vertical pipe his shop vac attaches too. See the 10:15 mark for a close up look at the bracket. The only problem I see is that you need a fair bit of Z-clearance to rotate the shoe under your bit, which might be an issue on some Workbee or Ox builds when you have material and clamps in place on your spoilboard. Neat idea though.

    Ditto for the Lead... Requiring an extra inch or so of clearance between the tool & workpiece gets pretty cramped. If you don't mount your workpiece right up against the bottom of your machine's Y travel, you can jog to the edge and at least avoid the workpiece & holddowns, which may give enough clearance if you aren't using long tools.

    That arrangement also looks like it effectively doubles the width of the spindle, which cuts into X travel (CAMaster seems fond of extending their gantries out beyond the rest of the machine, which neatly avoids the issues - along with allowing for nifty things like a side-mounted rotary axis with a dedicated second spindle), but it may be possible to get around that by rotating the mount so the tube hangs off the front of the router rather than the side... Although that would tend to give the vac hose more leverage to twist the Z axis out of true around the X - a deflection that's already measurable even with the spindly little water hoses from my spindle.

    ( my machine lacks a dust shoe as a political statement in support of free range dust )
