The last vase was cut from 1/8″ steel. With a jig saw. I blew through 6 blades but still managed to get the shapes close. The flap wheel helped me get them even.
Not wanting to endure the same fate again, I made a quick CAD drawing with some free software and sent it over to the local metals supplier who just happens to have a massive C & C plasma cutter. Seriously, this machine is like 15 feet by 50 feet. So they didn’t have any problems cutting up a 4×8 sheet of 16 gauge sheet.
These are the shapes I had them cut:
There’s enough to build two vases of each shape, drop a terracotta pot in the top and add a base with feet. The feet themselves haven’t arrived from southern California yet, so the build process has stopped for now.
