Does anyone in MMD-land have a source for 3/8" O.D. thin wall brass
elbows?  Other materials would also be fine as well, as long as the
inner diameter is not much smaller than brass tubing (i.e., 0.311").

Alternately, is there a bendable thin wall rigid tubing?  The brass
tube I get from McMaster-Carr won't take a 90-degree bend.

Cheers!
