I want to use a colon cleanser before starting my diet can anyone give me any that's good and not to harsh?
This would depend entirely on the forces applied to the pipeADD: regarding force applied (compression type, or 'load bearing' as I think you're describing): Longitudinal forces (along the axis) can be supported much better than loads applied in transverse (90 degree) orientationExample: cardboard can sustain loads applied to the ends of the piece (down on the 'holes') much better than loads applied to the sides of the cardboardIf you have access to a welder by all means use that rather than perforate the tube.holes always create a stress riser.
