Tonight I smoked the first bowl in my Peder Jeppesen Stack Churchwarden (68mm or 2-11/16" deep) since it sat for nearly a year while I ruminated what to do about the shank that won't pass a pipecleaner.
Eventually I settled on raising the floor of the shank with a mix of charcoal powder and high grade wood glue (same stuff as on the shank of a Cob), it still doesn't cleanly pass a cleaner but it's at least an improvement.
Then this afternoon I got the stem drilled to 4mm through 3/4 of its length and 3.2mm to the button, one of my better drilling jobs on a Churchwarden stem so at least that part of the pipe is now satisfactory.
The tobacco was a mix of Carter Hall and St. James Flake, the mix was fairly dry so it wasn't overly flavorful, but at least the Burley did keep the VaPer flake burning.
