Got my Wynn filter today for my HF DC. I had put the DC together a few weeks ago, but never really paid much attention to it till I was installing the new filter. There's been some posts here with pics of the MDF "top hat" style Thien baffle. And, I figured on making one of these shortly. But I got wondering today, can't you just use the collector ring(?) from the HF DC instead of making the MDF setup? Sure, you'd have to make the slotted bottom base out of something (MDF), but you wouldn't have to make the outer ring. Now, on the HF collector ring, it's got a tapered, short, funnel built in to it. Would this be sufficient to use as is, or would you have to build a top with the piping through coming down below the funnel? Even if you had to build the top and bottom plates, this would still be easier (and faster) than building the ring itself. Greg
