I am building a closet for my 1800 using open insulation and rockwool. I vent to the outside through insulated HVAC duct. I am wondering how to cool the motor. I know that those of you who vent air back into the shop use the chimney baffle like in Ed's video which also helps to cool the motor. The corner where I am putting the closet already has an unused 4" dryer vent opening to the outside of shop located at the top of the closet. Would this be enough to allow air to circulate? Also would the hot air exhaust through this opening or would outside air come in, or would the two fight eachother therefore requiring a second vent?
thanks,
Seth
