Yep, pretty easy.You need new wool, Stainless Safety/Hobby wire and some good pliers. I fashioned go/nogo gauge the same size as the ID of the tubes, so I knew I could slide the baffle back in without fighting or screwing up the wool upon insertion. You can get away with no gauge, I just made one after fighting a baffle back in and bunched up the wool bad enough, I had to redo it.
