K40 modification drawings

There is an acrylic box, which can be cut on a K40, to replace the stock fan. Converts from standard fan port to 4-inch (100mm) duct. My flex-duct fits snugly in the 102mm radius hole, and was caulked into place.

The air assist drawing has a small hole from main assist line to under the lens. The idea is that we create a small vortex over the lens, which blows out the nozzle, protecting the lens from smoke, while the main line provides air assist. This is fit to the stock head, with 52mm focal length lens, 12mm diameter.
