OK, I do not have money to invest in a real DC system, so am using a large
shop vac. Has worked fine to date, dedicated to one machine at a time.
Just build NICE router table with baffled dust collection system, author
claims it collects dust real well. Cabinet runs DC piping from back into
cabinet section where router is located. So it is not a design where the DC
piping comes up underneath the router (a better design in my opion). Can't
change it as area below router cabinet section is used for drawers.
Well, IF I am not trying to use dc for the fence and cabinet at same time,
collection is "poor". If I DO try to use DC for fence and cabinet at same
time, DC is minimal.
Question: Is it cabinet design, or the fact that a vac does not have the HP
needed to really move the dust? I am using 2.5" piping and accessories from
Rockler, so that can't be the problem. Have checked for air leaks - none
found.

Shop vacs do not move enough air to be real effective dust collectors. Most
shop vacs move around 100 CFM or so, where a dust collector may move 1000
CFM or more.
I use a dust collector on my router table. Connected below the table it
removes a fair amount of dust, but quite a bit is still blowing freely above
the table. I plan on adding a collection point on the fence too.

Bingo, we have a winner! Actually, more of a CFM/velocity thing rather than
HP. See the thread about flexible tubing for a DC for some good
explanations of how it all works with proper hose sizing, etc.

Yes, that is the problem. 2.5" plus 2.5" is too much. Use the DC/Vac on
the fence and a dust pan inside the cabinet until you can get a real DC.
Shop vacs are great for small areas, but it will not move enough air to
handle the double ports that you have.
