				I need ideas to pump air into my Stilo STF5 GT helmet which has several air ports, I plan on using all 3.  I'm trying to make a cheaper/beter coolshirt air pump setup.  I already have some 3/4" Type M copper pipe that I would like to use to (2) coils through a water bath then into my helmet.  Any ideas for 1. Cheap alternative to coolshirt 12v air pump? 2. Flexible tubing ~1.5" and ~3/4" 3. Small NACA intake ducts |
