[TowerTalk] congrete filled steel for tower base

[nb7v at msn.com]

Ken,  To be quite straight to the point: The cost of cuting the 5/8"thick steel x 2' tube filled with concrete, Boring the hole ( 24" tube will not EASILY slide into a 24" hole) and will need a large amount of concrete to stabilize it anyway. add a small crane to set it ( it has to be perfectly Plumb to go in the hole and is verrrry heavy) Even when doing this all yourself, Just the cost of equipment rental will be far more than doing the base as the manufacture suggests. 
Be safe the Manufacturer did engineering on the tower base for a reason.
