Ok...metal working noob question here...
I have two UDS that I built a coulple years ago. Currently, I use fridge magnets on the four intakes (3/4"). The magnets work great but it is time to step-up and add the nipples/ball valve. I'd also like to add the pipe up the side so I don't have to bend over everytime to adjust airflow.
My question is this...what parts do I need? What are they called?
I did search here, there and everywhere but didn't really find what I am looking for. Would like to be able to walk into Lowe's and say, "I need this..."
