For the record, 1 1/2" rigid pipe (black or galvanized) is the same size and same thread as the pipes that come with peerless projector mounts. I've used them several times. Right now I'm on a job where we need a 14' drop and used rigid pipe. I've also used it with odd shaped ceilings and soffits where I needed short pieces or needed to make a 90 degree turn on the mount.


The cookie sheet is a new one though. However, aside from the problem of leveling the projector, I like the idea of a big flat surface that I could mount cords and HDMI extenders to. ;)
