I've been vacuum turning my bottoms for some time. Using some home made by vacuum Chuck's with PVC. Worked very well. I have a large bowl that I need to make a new vacuum chuck for, looking at 10" or 12" diameter, with 12" length. Thing I'm wondering is, would sonotube be rigid enough for this? I looked at some 12" plastic pipe but it not cheap, and I can't seem to locate any offcuts from a plumber. Or is there something else out there? I am in Calgary Alberta. Home Depot has nothing above 6" diameter.
Any help appreciated!
