  1. Hey

    Decided to make a homemade bong out of a wine bottle (nice one).
    Haven't made one myself before.

    So I wanted to order a nice downstem.
    Got a question. What's diameter of 6 Arm downstem?
    $12.95 - 6 Arm Downstem with 12 diffusion slits fo water pipes |

    Need the diameter so I buy a diamond drill bit with right size.

    Thanks :)
     
  2. 18.8mm/19mm ... Im pretty sure thats what you asking . Thats the joint size. Maybe im wrong though....
