I have both. in the fence and I built a pvc shroud that grabs what it
can from the shaft of the motor.

When cutting grooves this does the best job below the table.
When cutting with the bit in the fence then the normal fence mounted
works best.

Neither is perfect. Some will still get kicked out the side.

I'm midway to finishing my router table and I'm contemplating the
placement of the Dust Collection connector hose. I've noticed most
tables have the hose attached to the rear of the table (behind the
router) but saw a limited few which had the attachment on the bottom
(under the router), thus, making me wonder if one has the advantage over
the other. Part of my thought leans towards the bottom placement due to
the gravity effect. The other part thinks it may not make a difference
with a powerful DC system. Therefore, what's the consensus amongst the
group?

Thanks
