Hi chris
I was just deciding on my pier hight today. I had wondered how high you could go. Like you said it would depend on how well engineered it was.

Hi Carl
Unlike you I am going to buy my pier pre made from Software Bisque.
I don't have the right equipment to make my own.
Your dimensions sound very good, considering the SB pier has a 254" diameter tube that is only 3mm thick, 12.7mm base and top plate. There are no gussets.
I was going to go for a hight of about 800mm. That hight is quite comfortable for me to lift the OTA onto the mount.

Cheers
Phil
