I recently came upon an old Medico estate pipe that takes a filter. Turns out that someone left a heavily used filter in it while it sat for the 30 or 40 odd years that it sat. Due to this, once I pulled the stem out, I could not get it back in. I am almost thinking that the moisture from the filter swelled the briar so much that I am going to have to sand out the inside of the shank. Has anyone here ever done this? What grade of sandpaper do I need to get the job done? Also, what is the best way to go about doing this?
