This is a simple easy detachable dust shoe (made out of tennis ball can) for my new Shapeoko 2 which use a Dewalt DW660 cut out tool as the spindle.
Notice, enable to use this dust shoe, the "Tool Free Collar" on the DW660 needs to be removed.
(The rotation of the Spindle Lock is not relevant to the use of this dust shoe. )
Here is how to remove it quoted on the Shapeoko Wiki:
Tool Free Collar Removal and Spindle Lock Rotation
Use a T15 bit to remove the 4 screws holding the front of the tool together. WARNING:You have to hold the tool with the collet UP. If you don't, the entire rotor can fall out of the tool and requires total disassembly of the tool to reinstall.Once you have removed the 4 screws and the collet nut, the front of the tool comes right off. Remove the snap ring and the tool free collar comes off.At this point you can also twist the black metal piece and yellow shroud 90 degrees to put the shaft lock on the side with the DeWALT logo.Removal gives you more room under the tool and makes it much easier to use.Use a 5/8" wrench to tighten the collet and the stock button to hold the shaft.
