Hi guys, While my scope is in Meade Hospital receiving specialist care and maybe a heart transplant, I want to pour a concrete pier to mount the ol' girl on for her home coming.
The idea is to fill a deep hole in the ground with concrete and continue upward inside a 'formatube' cylinder about 12" dia (30cm).
What I don't want:
is the concrete to be pushed out the bottom by the weight of the column of concrete in the tube.
I will have 3 x 1'" screwed shafts embedded into the concrete to take the base plate and this I don't want to move, yet the base plate will be in the way of pouring if I have it in place .
Sooo any tips, advice, is much needed and will be greatly valued.
best,
Doug
