Does anyone have a picture of a CG5 mounted to a metal pier?

I am getting ready to purchase a pier and I am a little confused.

Sean,

Thanks for posting your photo's

What I found was a collar on the McMaster's web site that will do the trick. I do not have your level of machining capability.

And then I will bolt from underneath.

pretty sweet! what's the thought on locking down the azimuth adjuster? Are you going to have to tap a small thread? Do you have a link to the website you referenced? Does he machine CGE plates? LOL

I will probably drill and tap for the azimuth adjuster or may try to go without as the plate I will be attaching to rotates.

Here is the cat. page. As you will see I just searched for a collar of the right size.

Hello, Been thinks of building a pier myself. Was wondering of the collars which one did you choose. The Black-Oxide, Zinc-Plated or Aluminum or Stainless Steel.
That seems to be a good idea on mounting the CG5 without some fancy machining :-)

thanks

This is zinc plated steel.

There is a page where you make choices as to diameter and clear hole which in turn leaves only limited choices in other areas. Thickens of collar for example.

McMaster is great. I got something else form them that I am going to use on my 12.5" String Truss as part of an update/rebuild of that telescope.
