The reason I asked the first one I built one I thought that I did not need a ventilation system, Wrong with in minutes I could not see what I was doing. Had to stop and a venting system. What are you using on the door flap, it is red.Yep...in the 1st pic on the left side note the box with the filter low near the floor. It's connected via cardboard ducting to a box fan in the shop window.
High on the right sidewall is the intake air filter.
Hoping to get a nice down/side draft. We'll see!
