I need to fit a piece of PVC over the end of my blower to make a tube to blow out the gutters. My question is: if I take a 2 inch diameter PVC pipe, heat it and squeeze it in a vice to an oval shape, will the ID be at least 2 1/2" wide to fit over the end of my blower? I would think it would but I'm not smart enough to figure it out. Thanks for any input. --Dave
