cross-posted to r.c.m. as the level of practical experience therein is
likely to be high. r.c.m.'ers should note that for wave-guides
maintaining
the (x-section?) dimension following the bend may be quite important.
Cut 4 pieces of flat stock and solder them together?
Ugly and a PITA, but you can avoid the crinkled / streteched sidewall and
Wavy top and bottom.
My fuzzy memory about the little bit of rudimentary theory I used to know
makes me think that the OUTSIDE dimensions and surface of the waveguide
plays an important role. Or was that a dream?
Laser / plasma / Waterjet cut parts can be reasonably priced if you have a
non- swamped shop near you.
