Swaging questions

[Brian Duff]

One more swaging question .
When using a roller swaging machine should the swage be rotated 90* for the second pass, or should the ridge be left intact and the swage pulled the same orientation twice ?

I have been taught that the swage should be rotated to yeild a more 'smooth' apperance and feel(safer), and to force more metal and more pressure by pushing all the material into less space.
Then the other day somebody once again asked the question, doesn't that push the swage open by pressing it 90*, or cause excess fatigue right off the bat ? I always have argued against this , and turned my swages. Today I noticed once again that the swages supplied by Selden Masts have the ridge proud on each side, so whats up ?
