OK, my wife found a piece of 6" sewer and drain pipe...24" long with a coupling that will make it more than 26"...not sure if this is ideal, but its on its way to me as we speak. Once I see if I will know more. But I figured I have to build it up on the ends anyway to use the roundover bit...so this is a "possiblilty". here in vermont you have to make do sometimes.
