Pier help for CGEM

[originaltrilogy]

I have just bought new GGEM mount and would like to build pier.

I am good welder and can make most things yet need a design for a good pier for photo taking with CGEM.
Does anyone have CGEM design?
Did you use top plate from tripod or make new top plate?

How to handle bottom access for bolt?

thank you for any help.

I'am thinking of putting a hand access hole in some 200mm NB heavy pipe for the one i'am doing next for the HEQ5, will just fill it with sand up to the hand hole point :). As for the top i'am just going to machine a peg up for it, piss easy. If its a long term temp or perm you could make another top plate and bolt top plate onto pier top leaving a small gap for adjustments, that's how alot of designs i've seen have being done.
