Using a 5 gal bucket/top and 2" PVC pipe I made a simple vortex collector
and put in front of a 9 gal Rigid dust vac. This rig connected to, one at a
time, table saw, table router, miter. I dumped the current wood contents
of the vac on the floor and vac'd again with the cyclone in place. Id guess
about 95% of the material remained in the vortex container. The big
advantage being that the HEPA filter will stay clear now, maximizing
suction.

Now you've done it. You used yankee engineering and made a home-made
cyclone for $3 that will only perform at 97% of the efficiency of a
$500 laboratory designed cyclone. You have probably also reduced the
airflow of your vac by another 3%, giving you an efficiency that is
only 94% of what you would have had if you spent another $497.

Great job!

Very cool. Any chance you could post a pic of it somewhere (or email
to ryan at jimryan dot com)? I'd like to set something like this up.
I assume you used the hose that came with the vac to connect to the
bucket, then another vac hose to the tool? I have a small Rigid shop
vac, will that do you think?

I'll second that request. Or at least let us know which fittings you
used.

Good luck, but that's not my experience.
I have a commercial Triton separator. It traps 95% of the debris, but the
finest 5% goes through and collects in the filter. The vacuum stays almost
empty, but the filter clogs almost as quickly as before.
Maybe yours is a better design...

Ok...ill post some pics. I have a 9 gal Rigid so that pretty small. It
takes a day of sawing to fill that so its fine for me. Yes. I used the
shop vac hose and some additional clear hose I bought at Rocker.

Thank you. Looks like a solution for me...
