Here is a pic of my pipes.
The pipe on top (I call it my driver) I made it just for the terminator-c because of the diameter. I also made the adapter for the stem to fit the mouth piece on the term.
Corn cob pipe on the left is a converted used pipe. Doesn't even need a battery to get a nic buzz...LOL. Middle corn cob pipe is another conversion. Pipe on far right is all hand made. The switch mechanism I used is similar to the jazz carto pipes switch.
