I need advice on what i should do to make a pier. how deep should i make a 24 x 24 x ??? hole for a 12" tube? I want to make it with concrete.also Can anyone lend some pointers? I will be using a cpc 1100 on a wedge with the orion short tube piggy backed for a guide scope.will i need a plate made? Please help if any of you have done this let me know. Thanks!!
I have an 8" concrete pier build from scratch using this websie as a guide (especially in how to build the bottom and top plate). Here is a pic:
I too dug about 4 feet into the ground and it is proving to be plenty stable carrying a load of about 79 pounds (G11, CW and scope).
Very nice setup.
did you do a tube 4 feet into the ground or is there a base also? Nice set up by the way!!
To be honest, I used a post digger and just took an 8 foot Sono tube 4 feet into the ground. So far so good, like I said it is plenty steady for my set up. If I did it again I would go the extra distance and pour a "foundation" with rebar laid horizontally in the ground.
Thanks Steve!! I guess I will go deep and a little wide.where did you get your plates at?
I had them cut at a scrap metal shop in town. If I remember correctly I paid $20.00 for both of them. 10x10 inch and 1/2 inch thick and used 4 12mm threaded rods 100mm long.
Steve, I'm assuming there 4' of concrete pier above ground level, in a "had to do it again" scenario is that a good working height (a bit higher/lower?) Anybody else have thoughts on the pier height (minus the base/leveling plates+mount head). Thanks, Marc
I would not go any higher than 4 feet above the ground. I'm ~5'5" and can manage everything fine. It was the perfect height with the CG5 but now that I have the G11 it is a pinch tall. Most importantly, no one can see it above my back wall...
I did the exact same setup with mine too. 4 feet deep, 8 foot sonotube.
Putting more weight on mine now and planning even more weight, so I got a new pier from software bisque and will be digging a much more solid setup. Squaring the hole not just a post. Will be digging deeper as well, just to be on the safe side.
Thanks for the reply Lisa. I went down 24'' square then also went with an 8" tube another 18" in the center. I got 2 free 1/2 " plates and measured and drilled the holes myself. Trying to save money for other things I need.
