    Default WDS-400 dust ports

    I have a WDS-400 that I need to modify to improve its dust collecting abilities. I've found a few threads where people have talked about undertaking the same process and a few ideas about how to do it, but haven't been able to find any feedback on what mods were done, or the effectiveness of the mods.
    My initial thoughts were to replace the curved crappy plastic cover with the useless 2.5" dust port with a flat topped ply cover, and make it taller to allow more air movement over the top of the drum. I was unsure about what to do for a dust port/s though. the internal dimension of the existing plastic cover is 160mm, and if I replicate this with a ply cover, a 6" pipe will fit in but not have room for a BMH. This would also leave 5" to either side where the dust would need to be scrounged rather than just sucked straight up. Would I be better off with 2 x 4" ports with BMH?
    Or could I cut 2 parallel sides of a 6" BMH, allowing it to fit within the top, and have the partial BMH to help scrounge out to the sides>
    Thoughts?

    I finally got around to doing something with this.
    I did away with the plastic cover, replacing it with a ply one, and used a 150mm Y and some re-shaped pieces of 150mm pipe to widen to pick up area. I had to shave about 30mm off the top of the 45° bend to get the width of the spread right.
    The first two photos are before I put the front on the new cover.

    The following photo shows the difference between the original cover with the single 65mm extraction port and the new cover with 2 x 180mm x 60mm ports.

    I ran a 380mm wide Blackwood board through it, and with nothing more scientific than wiping my hand over the finished board, it works beautifully.

    Probably a good idea to bolt the sander down before it gets sucked into the DE. You certainly don't do things by halves.
