The old cake came out easily, and confirmed my suspicions about the state of the chamber floor.
The second pic below shows a dimple in the centre of the chamber floor.
My routine with stem fills is to use needle files to remove the excess material and then move to 220 and 320 grit sandpaper to smooth and blend the fills with the surrounding vulcanite.
0000 steel wool removes the last of the sanding marks in preparation for buffing.
The rim of the bowl was crusted over with lava, especially around the rear edge, and the face of the bowl had a rather unfortunate patch of “road rash” from exuberant dottle-knocking on hard surfaces.
The tobacco chamber needed a good reaming, and it appeared that the chamber had been over-reamed, leaving the draft hole high above the chamber floor.
While the stem sat, I refreshed the stain on the stummel, applying a two-colour contrast stain of Fiebing’s Dark Brown leather dye over Black.
Then I found my ken knife and scraped the rim clean of its lava crust.
The factory rim on this Kaywoodie 13B is not flat but beveled slightly inward, so I had to work carefully to avoid gouging the high outer edge with my knife.
Next up was a good reaming with my Castleford reamer.
Based on its condition as found, I’d like to place it somewhere in the 1960’s to early 1970’s.
If anyone can clarify the dating on this pipe, please let me know.
