The Stainless Steel Octagon Cup is a great challenge for any welder. This particular project is fun for TIG welding.  It is 16 ga stainless steel 304. The sides come tabbed together for easy bending so you can get right to the good stuff. This kit comes with: 
-Octagon Base 
-2 Rectangular Sides  
 
When assembled the cup is roughly 3.5" wide x 3.75" tall. Total weld required is 42".
