Jules,

Another way to cap the tube ends with a dowel insert, is to make the dowel about 1-2 inches shorter that the tube. Center the dowel, and stand the tube vertically. Fill the top end with RTV or similar sealant. After it hardens, swap ends, and repeat the process. I have two tubes done this way, one 20 years in use, and the end plugs are still perfect, with no UV damage. Not as messy as creosote, and if you ever need to do so, you can dig out the plug with a knife.
