Golden Rivet - . ."If the LAE wants three threads, he should have three threads - at the end of the day its the LAE who is signing the CRS.". .. .I know what you mean, but don't go too far down that road..... .The LAE is 'only' signing that the job has been done iaw published procedures. The licence doesn't give you the right to demand your own preferences. If he disagrees with what's been published then there is a better time and place to argue than during the job.. .. .Too many LAEs in my life have thought themselves better qualified than the design organisation and it always means trouble - he should read notice 3 if he thinks he can do everything.... .. .(anyway, 1 1/2 threads have always been good enough for me, but split pins are better!) <img border="0" title="" alt="[Wink]" src="wink.gif" />
