I am going to be running off of a maxijet1200 which has a 1/2" output. Is a 1/2" pipe too small for drilling a slot, or should I upsize to 3/4" or even 1" PVC for the slotted pipe? I bought everything to do it with 1" but am thinking smaller might work just as well and less adapters required. I just want something to hold me over until the new design comes out.
