I've been brainstorming what to do to keep as much of the flex vent out of my setup. I just ordered another 90 12" elbow to add into the bottom of the 5' run of straight rigid duct and I'll look into adding a 1'-2' of rigid duct that I can add and remove when I work in the shop. This had crossed my mind a decent amount because I want this done correctly.

This is also something I battled with simply because I have a garage door to do my venting, and that's it. No windows or anything. My plan for the near future is to make a board that goes along the bottom of the garage door where one side has the duct exhausting from, then I'll have the top of the garage door as my 'make-up' air. My area is always really windy in the opposite directly. I've thought about this a lot because I don't want all my vent work to be done and have it be non-functional because of an oversight.

I actually read about this at the beginning and implemented that in the setup last night after doing my incense test. It seems to work better from the incense test, but I guess it really depends on the air flow in the work area.
