If you go to Lowes, they sell 12" x 24" sheets of expanded metal. It is by where they have the fancy aluminum sheets and various metal items (ie angles, stainless rod). The pieces are individually packaged in cardboard and cost about $10.00. You may have to look for it, but it shouldn't be too hidden. Made charcoal basket with the lathe, really didn't care for it, but everyone has a different idea about what is good..
Currently using a Char Griller Offset, 2 UDS and a OTS. Continuing to look to add to what I currently have.
