Step 4: bending the new arc

I did return to Discount Steel (third trip in a week), and bought a five-foot, 1/8" aluminum pipe. The outside diameter is very close to 3/8".

Now I'm carefully bending this pipe to match my pattern (Stabiliser #2 at diycamera). I'm making a series of very small bends in the pipe, using a bench vise. My workbench is in the garage where it's 12 degrees F, so I'm repeatedly running outside, clamping, bending, unclamping, and running back inside to plan my next bend. Slow progress...
