That's what I was thinking too. You'd have to make a couple of laps around the garage for '50. I seen on the second post where they said fifty was best but try to get at least 25'. I'd wondered about make some type of aftercooler for mine. Buy a roll of copper tubing make up a coil in a box with a fan blowing through it. Dad suggested an air conditioner condenser, but I,m not sure if it could carry volume of air. smile
