with this mod were getting a thermal separation between a metal stem and the tip. In other words our stem doesn't get hot anymore. I just put an glas tube between the tip and the stem. Glas has a low heat conductivity, so the heat stays in the cap and doesnt travel into the stem too fast. examples for heat conductivity Glass: ca.0,8 Wood: ca.0,14 (glas alternative) Stainless steel: ca.15 Titan: ca.22 copper: ca.300 Plus our stem gets longer and the condenser doesn't go into the tip anymore which is another heat source we eliminate. The adapter between the glas and the stem is the harder part to build. But with a little trick we get it done without an lathe machine. Build this at your own risk and only if u know what ur doing ;) -DIY- Adapter (left) you need: -Tube 8mm/6mm (Titan or stainless steal) -high temp o-rings 6mmx1mm -Dremel with a ca. 1mm cutting disc -drill 5,8mm -caliper+black marker -saw -file / san
