I attached the two DXF file in AutoCAD 2000 format
Note that this was designed for a Bosch colt router and a K2CNC Bosch holder
Dustshoe1.dxf is the top piece
Dustshoe2.dxf is the top piece
There are several layers in each dxf file
The screen shot below shows what the files should look like
I have had people say that layers are missing when I send them a DXF file, so check yours against my screen shot
DXFs would make things better
(I already have a dust shoe partially made that lacks a brush)
I like the machine setup you have and how you've conquered dust.
I've ignored it for the past year minus shoveling it out once in a while. Then I upgraded to a shopvac with a dust separator.
Now to fix dust at it's source.
