Hi Folks, I've decided to make a pier to reduce some of my setup time of an evening. I've got good access to just about any size of RHS or Schedule 40 pipe I want, and a full machining shop at my beck and call, so the actual fabrication shouldn't be too much of a challenge. What size should I use for my pier though ? I'll be mounting a Meade Ultrawedge on top of the pier and then my 10". I'm sure bigger is better, and I could go up to 16" schedule 40

, but I reckon somewhere around 6" is probably overkill enough once it is filled with sand .. any thoughts ? Is 6" too large ? Is 6" too small ?
It will be out in the open for the time being, but once we finalise our move, I'll unbolt it and it will become the pier for the roll off at the new place.
Thanks in advance for any suggestions !
