Hit up Industrial Paints and Plastics in Richmond for your plastics needs. Its near No. 3 Rd, not sure how close you are but you might want to call them up rather than drive all that way incase they don't have what you need. I haven't seen much round stuff in their cut-offs but I think they stock up to 4" diameter acrylic tube. They'll have all the methlyene chloride and/or weldon you'll need as well. Best of luck.
