What better way to celebrate Pi day than to eat it? But what if you love cookies? Last Thursday we tried something new and fabricated a Pi shaped cookie cutter out of sheet metal.

The first step was converting the drawing to a file to be cut on the water jet, and making a metal version of the cookie, just because…

Next, we used the water jet to cut out a rectangle the right length, complete with rivet holes. We contemplated which order to make the bends so that the bends wouldn’t collide with the un-bent material, and we decided to start at the inside of the legs, and work our way around so the rivets would be along the top. After careful measuring on the model, we made the first few bends using a hand held sheet metal bender, and the larger vice mounted bender.

We made the last few bends, and after a bit of final adjustment the result was beautiful!

Happy Pi day from ProVolt!
