Here is a trick I learned from Tim West. Believe it or not, it works. For the cracks in the bottom of the bowl or a pipe that you want to build a quick cake in, Completely dry some of the tobacco you intend to smoke in the pipe. I mean get it tinder dry. Mix the tobacco with a quality grape jelly (we use Welches or Knotts) and smear a thin coat in the bowl. Set the bowl aside and let the jelly/tobacco dry completely. When it is completely dry, load the pipe to the top tamping only in the center and smoke it ALL THE WAY down.
Some people recommed using honey in the same way. The problem with that is the honey melts and form a puddle in the botton of the pipe that turns rock hard. The jelly won't do that. I saved a pair of high grade, high dollar Celius' using that method.
Clogeo3, I haven't owned a Yellow Bole for 40 or 45 years so I can't advise you.
