I'm pretty close to deciding to go with 6" S&D PVC for DC ducting but one particularly gnarly area is going to give me some trouble. It would have been trouble with metal ducting as well. But I need to come out the side of my DC closet and get up into the rafters in a fairly short area. Using fittings to make the bends is going to eat up a lot of that area. I think I can still get gradual enough bends for DC and clear my space problem if I can bend the PVC. I asked a few days ago about the PVC heat blanket benders that Bill Pentz site mentions. A few folks replied that they were going to be expensive and some Google searching shows that option even costlier than their estimates. I dont really relish the idea of torch or heat gun heating with all the dangerous fumes. So I'm sitting here today and had either a totally great idea or a totally foolish one. Can I use a steam pot and plug up both ends (one would have a opening for the steam) and bend the PVC with steam?? My next thought was - Naw that'll never work because I've heard of folks making steam benders for wood out of PVC so it must not get hot enough for PVC. So I searched past posts here about steam bending, and voila - found a bunch of warnings about using PVC as a steam chamber as it gets soft. Geez, maybe this isn't such a wacky idea??
Anybody ever tried this?
