Thanks Chris, I found them on a Google search late last night. Good to get a recommendation from another 'pier builder'

And close to home. Did you use Black steel pipe:
http://www.steelsolutions.com.au/ste...ium-c-103.html I was looking at the 164x4.8mm
I've established that my pier height needs to be approx. 850mm from floor to top plate. This takes into account a leveling plate and some adaption plate for an NEQ6.
