Any info on what others have done would be appreciated.


If you buy a real DC (which I also highly recommend), you don't have to change
the ports on your tools... just hook the 4" line to a reducer and thence to your
tool. OTOH, if you have a choice of ports for your tool, go with the largest.
No matter what you do, you'll be better off than you are now with that howling
shop vac.

I have a Penn State DC with the optional muffler and you can easily carry on a
conversation while it's running without having to shout. Try that with your
shop vac.

BTW, no matter what kind you end up with, invest the extra $30 or so in a
cyclone trash can separator. Your impellors will thank you (for years).

choking down from 4" to 2" will lose you a lot of the benefits of the
DC. it will work, but is unlikely to perform better than the shopvac.
figure on setting up 4" ports on all of the machines you can, even if
you have to cut some sheetmetal.
