I never thought to ask bunnings they dont have it on the shelf , will check it out .
I believe theres some some tubes sizes with a 1.2 mm wall .
My ground board wasnt running freely , Ive been looking at few things and couldnt see anything wrong over and over
.
I came back to the teflon for some reason I thought backing off the torque on my drill was the go when mounting it again instead of picking up a screwdriver. Though i couldnt see it as the screw bit i think it must of distorted the teflon slightly on one or two pads . , I drilled out the the area around the mounting holes and put in clean ones and its working well now .I will chase up some 1/4 inch instead of the 1/8 I have now .
