This strut is in the correct position to be pressed. Notice that the mark
which identifies the location of the seam is at 45 degrees to horizontal.
In fact, any 45 degree location is fine. In otherwords, if the end of
the pipe was a clock, it could be at 1:30, 4:30, 7:30 or 10:30.
If you put the mark at 3:00, 6:00, 9:00 or 12:00 the pipe will split. |
