I glued the second set of bending blocks together this evening. They're a mirror image of the first set since I'll need to do one for the left side and one for the right of the fuselage.

I was able to make a test bend. It didn't look awful, but it didn't look perfect either. The tubing kind of flattened out especially when bending around the second block.

And there's an ugly crease near the transition from the first to the second bend. I'm not sure these blocks are going to work.
