Yep - I have a drill and I was going to buy the smaller lengths. Just don't have a saw to cut the notch. Perhaps I can just mount the 5" cap 1/2-3/4 of an inch below the pipe creating a gap all around for the feed to fall through - or drill holes close together in the shape of an arch and then take pliers and kind of snip the PVC off. It will be jagged but still functional.
