Hey Phil I just got mine working as I just got my DC. I ran an add in Woodnet that I was looking for one and a nice guy in Florida hooked me up with a Penn State 1-1/2 HP portable unit and it works great. I sanded and planed for about 4 hrs. yesterday and filled the 20 lb can with chips and dust and the bag didn't even have a handful of stuff in it! I'm going to get a high quality felt 1 micron bag and see what happens next. As you can see in the photos I mounted mine right on top of the separator lid. I wanted the shortest and most direct connection for the inlet into the DC. Also, as you can also see I put a lot of duct tape on the connections as I was paranoid about any air leaks because the 90 degree elbows were the metal ones that you could actually twist for the best angle. You have my permission to post these on your site and on Woodnet if you want as it was your design in the first place and I thank you for it.
Aloha,
Rob
