Actually, if a chase means a "box" around it, I had considered it. They set right next to the stairs (next project_need refinishing), so as soon as I figure out how to run the camera

, I'll post pictures. Kidding about running the camera...can't run a camera?--shouldn't be running a miter! I guess since the pipes are uninsulated, I didn't know if that should be done first or at all--are there any hazards I should be aware of? A chase would certainly make the "unfinished look" look a lot better!

So about the chase...preference on materials for it?
OH yes...THANK YOU FOR YOUR HELP!
