DO NOT pour this pier with any of the sonotube below the top level of the pier base. When ALL the concrete is set up you will have the ability to strip off ALL the sonotube. Wheter you do or not makes no difference, but you will have the ability.

If you dig a two foot deep hole, the bottom of the sonotube ought to be two feet from the bottom of the hole.
The pier base must be larger than the sonotube for stability. I suggests at least 2 feet square and 2 feet deep with 36 inches of sonotube on top of that. Use a hand saw to cut the sonotube off.

I think I understand. I had been researching sites where others have documented their pier builds like this one where the sonotube appears to have been simply placed into the hole and concrete then shoveled into everything somehow.

Not necessarily fingering all that have done this, but by what you (and others) have said here, I might have been fortunate in having these concerns anyways.,

Thanks again. Will set about rethinking my plans again.

Cheers!
