Well, I finally got the jig set up with the usual amount of head scratching. I thought that the 8 mm collet reducer was missing, so that made for a 25 mile trip to the not-so-local Rockler shop. Discovered it later in the same bag as the included router bits. Duh! Decided to use two routers, so needed to run to HF for the 7/16 bushing and then back to Rockler for another collet reducer, at which time I discovered a 50% off sale, so managed to kill 45 minutes browsing.
Finally ran a test for through dovetails. A little more tearout than I anticipated and the joint was way too tight. Brought out the mallet and still couldn't get it to fit. Then I recalled the directions offered some adjustments for just that circumstance. Could not pry the joint apart (it really was tight), so I decided it was time for a break and I'll attack this again tomorrow.
Bottom line: I am encouraged. I hope to avoid Rockler tomorrow. By the way, I picked up two Kreg hold downs and a bag of glue brushes for half price.
