I'm having a heck of a time finding 321 Stainless mandrel bends in anything
larger than .049 wall. I'm trying to get 4 - 4" Center Line Radius, 90deg
bends in at least .065" wall. I've tried calling 4 places and researching a
hundred others online and my last hope appears to be Woolf Aircraft Products
(http://www.woolfaircraft.com/).

Is .049" wall beefy enough? If I recall, it seems that most people are using
material that is larger.  RacingBeat/MazdaTrix sell .125" wall but only in
"mild steel" not stainless.

Anyone else have any suggestions?
