Thanks Schreck for the reply. Your pictures show where I want to add the baffle. Only I had not planned to remove the spiral.I had originally planned to put an extension on the bottom of the ring then add some sort of container to catch the chips, keep in mind I have a homemade trash can type separator that I use on my planner.I plan on a proper Thien separator at a later date. I have six more weeks of light duty no more than 20pounds. I got my Wynn filter the other day, so I plan to make the donut to mount that, then a donut for the bottom to mount water softener container that is 18 in in diameter. My collector has the two felt bags, will replace the top with the Wynn filter and solid barrel on bottom in place of clear plastic bag. want eliminate that clamp strap thing as it is a real pain to get on. thanks again for your reply. shorthanded
