So I'm very new to this life first off, so my knowledge of certain things is limited. Which brings the question....I would like to build my own conveyor dryer (like many have) I have a plan and design my only big question is how big should I make the drying chamber? I was thinking 4' but if I could "trim the fat" I will to save room and money. I guess another question is more for opinions and that is what is the optimal chamber length? Thank you for any and all help you are willing to give out.
