american made vaporizer

A volcano/v-tower heater. Like the volcano, the herb chamber screws on, but different types of chambers and heaters can be used interchangeably. I plan to first make a homemade adapter to attach a volcano chamber to the top of a Q. Then ill try to make my own volcano based (huge, wide/flat)...

What vaporizers are made in the USA? I'm not talking about being designed in USA and made in China or some other foreign country, I'm talking about being designed in the USA and made in the USA and made with USA materials.
