Sleeve it. Try this instead of rivets and glue. http://alumiweld.com/index.html If your going to split the sleeve on a table saw make a good pusher stick. I make one from a 2 by 4 about a foot long. I cut a 1/2 inch or so about 10 inches long. This leaves a couple inch step to push it through. This will keep your digits away. I assume your going to use a fence? You can also shorten a jig saw blade and cut it that way.
