Step 1: Cut Some Strips
Cut a sheet of stainless steel to 9.7" (3" * π plus enough overlap for the ring to stay together) long, then cut it the other way into 1.5" strips. I used a hydraulic sheer.
Step 2: Make Them Round(ish)
Shape the strips of metal into rings using a slip roller. The roller I used is a little too big to roll a 3" circle so I ended up with C shaped rings and just finished shaping them by hand.
Step 3: Weld (or Maybe Burn) the Ends Together
I set up the TIG welder, which I had used a grand total of once before (in a class last week), clamped a couple of pieces of scrap together and tested a spot weld. Success!
For the rings I overlap the ends by about a third of an inch, clamp both edges, welded the center, remove one vise grip, weld, repeat on the other edge. I only managed to burn a hole in one or two of them :-)
A quick cleanup job on a sander and they're ready to go.
After making these five I made another batch of nine 3.5" rings.
Step 4: Test Them Out!
Using this recipe we made the dough, cut it with the rings, add a bit of homemade apricot jam, use a piece of aluminum foil as a cone to sprinkle the streusel around the edges, toss it in the oven.
Step 5: Sucess!!
These cookies are definitely good enough to be worth showing the world how inept a welder I am.
