I made a belly pan dust collection for my BT3000, using a commercially available, cheap dust pan from one of the woodworking supply houses with a 4" hose fitting.

It seems to work effectively very simple DC belly pan under BT3000. Not tightly fitting I wanted to allow air in to carry the dust to the DC, pulling on a close cabinet is not a good idea. SO the plywood sits on the stand, not screwed down or anything. So there's air coming in thru the ends and the Shroud dust port arc. This is an actual picture after use, not cleaned up. The DC is connected with two 4-inch hoses to the shroud and the belly pan. The biggest issue is if I don't use a zctp the thin long cutoffs get sucked in and end up in the Shroud hose jamming it up.


The BT3000 end panel is removed for photographic illustration; I just set the plywood setting on the bottom flanges of the saw after cutting an opening in the plywood and fastening the plastic pan. No modifications, holes or attachments were made to the saw.
I've been using this for years.
