Dust collection for my 4212 jig

I picked up a porter cable dovetail jig 4212 yesterday and was wondering what to use for dust collection. I found hoods for the 16" model but not for the 12", any info would be appreciated. thanks!

A year or so ago, Smitty had his dust collection design for the dovetail jigs printed in Wood Magazine as a top tip. I am on a company trip, so when I get home, I will look it up and see if I can get you the plan.
