i have a 7" 14mm joint bong that im going to be using it, mark suggested at first that i get a 14-18mm converter and use the tjds... but i wasnt thrilled about having to buy extra components, as the price as is is a strech for my financial situation... so he told me that the 12mm slide will fit and make a seal with the 14mm joint, and i asked him how long the actual slide was, he measured one and replied that it was 3", so i should be fine just using the slide itsself as a downstem
i also have a nice eiffel tower shaped bottle that i want to drill and drop a 12mm downstem into, but ill need to purchase the right drill bit, so that will wait for later, this will make an awesome stealth bong for me, as my parents are used to seeing the bottle on my dresser anyway, and its 13 inches tall, with a relaitively small chamber volume, but relatively large volume for water in the base
i wake up every morning hoping that ill log on my computer and see the email from mark saying my unit is ready to ship >.<
