simple router table - attach vacuum hose to router box, or use Bosch dust adapter?
I thought I'd seen this discussed before, but I cannot find anything about it now:
I want to build a simple first router table with a Grizzly plate to hold my Bosch MRC23 router in its fixed base (so it's then technically a MRF23? stupid naming scheme.).
I just got the dust collection adapter set (haven't tried it yet), and it includes one adapter specific to the fixed base.
I'm wondering whether it's preferable to the Bosch dust adapter under the table, with the router box serving only as a catch-all for whatever bypasses the Bosch piece, or if a vacuum-tight box always works better than the adapter pieces with their big collet/bit holes.
There are of course other consideration such as convenience/durability (it's easier to make and work with a tilt top for bit changes if the box doesn't hang from the top; mounting the hose so it doesn't crack the Bosch adapter when the top is tilted up is harder, however), and a fence-mounted dust hole will no doubt affect the under-table performance somewhat - I plan to build that sort of thing too, but not right away.
There's also the part where the box has to be somewhat tricky to divert dust past the router on the way to the vacuum hole. I noticed that a lot of box designs have a diagonal U-cutout baffle around the collet of the router for this purpose - with the Bosch adapter, all the dust that falls through (but no more than that) falls onto the router.
But what I'd like to know from others' experience (or theory) before I find out the hard way is how the Bosch adapter does, compared to a box, at
a. clearing dust off the top of the table
b. will much fall through?
Incidentally, if using a vacuum box, is there a way to use incoming air flow to blow dust off to the side (from the collet and bearings, etc.), e.g. with a pipe pointed at that area of the router, or does that plain not work because whatever air flow you use for this is lost to sucking dust into the box in the first place?
