hello chaps and chapets I'm going to be making a pair of strut braces next weekend and the rear is also going to act as a mounting for my harness assuming that won't pose any msa compliance issues? I know I need to use seemless which is no problem but I dont know what wall thickness and grade to use? and if its going to be a mounting point for the harness i assume it also needs to be a certain diameter for msa compliance, again unknown to me. if any one with the blue book could shed some light for me I would be gratefull and yes I know by now I should have my own copy but things are dragging so I'm trying to put it off untill all the basics are done. cheers all
