Hi guys i am relatively new to this but i would still appreciate some help. I have my reflux tower all made and ready to go but my problem is how should i attach the tower to my beer keg? I have seen pictures on the internet and i seemed to see many beer keg boilers that had a bowl shape object joining it to the tower. The bowl appeared to be something like stainless that was polished nicely. Any one that has built a still with a beer keg for the base or anyone with knowlege of this please help me out. thanks guys
