Any help or links would be appreciated.

hi there is a pier head you get when you buy a short pier from skywatcher you then simply weld a pipe onto a plate that has the same diameter as the outside of the eq head the pipe needs only to be about 3cm proud of the plate .you then drill three holes into the pipe side to accommodate the screws that hold the head in place in the pipe .the head comes complete with a bolt from underneath to hold the eq6. the plate is held in place by four 3/4' bolts to another plate below the aforesaid plate which helps you adjust for level.i have made two of these piers and they work well for a 10' newt and a c8,the short you can buy from myastroshop for n$70 and have a look at the bintel site pier for the design of the top two plates .it is the top plate on that type of pier that you weld the pipe and cut a hole in the plate as large as the diamiter of the head. good luck qld
