Awhile back I picked up a Bruce Peters bench made pot at an antiques store.Got home
and gave it a deep cleaning (I thought).I used a dremel to clean the bowl down to clean
briar,scrubbed the vulcanite with oxyclean and scouring pads,cleaned the airway until I
could pass a pipe cleaner thru cleanly.And it smoked ,,,,ok.Had a bit of gurgle and no matter
the pack I had a couple relights. Tonight I took a small drill bit just a tad bigger then the
draft opening and using pliers I hand drilled the opening to about 9/32.(that's if I read
the bit box correctly)The stem had a stinger,one of the twist in ones that had been cut off,
and with a slightly maller bit I managed to ream it open a bit further and the stem as well.
then using the smallest bit I have I worked the bit end so a PC would pass very easily.A quick
wipe down and swab in the bowl and That old pipe smokes like new.Easy draw,no gurgle,and after
40 minutes no relight.I would like to thank @Pugsley ,the book you sent is full of good advice and
ideas.
