I've spent quite a bit of time lately reading through this forum, and have learnt a lot about what is required to get proper air flow and extraction. I'm currently using a Jet DC-1200 with pleated filter, but that will be replaced with a much bigger blower on a cyclone that is vented outside, and I will upgrade to 6" ducting.
In preparation for that I want to upgrade the dust ports on my Sawstop tablesaw. It's the Professional model which has an internal plastic shroud. I estimate that it chokes down to about the area of a 3" hose, so while it might sound good to have a shroud internally connected to a 4" port, the reality is much less useful. As you can see in the photos it is quite restricted near the bottom in order to clear the mechanism and the side of the cabinet.

My first thought was to modify the shroud, grafting on a new lower section that had a larger cross-section, but I now plan to remove it and put a 6" port with bell-mouth flare at the bottom rear of the cabinet. http://ift.tt/1IZ71IH
My question for the forum is where to allow the air to enter the cabinet? There is an access panel (200 x 185mm) at the top rear corner of the RHS, and in the photo you can see a similar sized panel at the rear of the cabinet. That panel is inline with the blade and above the dust port.

The motor cover is moulded plastic so would be very easy to put holes in it - or a louvre panel.

Which side of the cabinet is better to draw the air in from?
Thanks in advance for your help,
