[TowerTalk] Base stubs for old AX-series tower

[ve4xt at mymts.net]

Don't blow a section if you can't find stubs. 

Find a local steel supplier and have him cut you some channel iron. He can probably also drill holes for the bolts. Have him drill a third hole towards the bottom to insert a longer bolt (to grip the concrete and to tie to rebar if you're using). 

The channel iron might be a bit of overkill, but you can then weld to it if you switch to a different tower.

I tried to check with Criticaltowers.com to see if any of the BX-series stubs would work.  Basically they told me that they had no parts for the old AX-series towers and never had any at any time.  Unless I find useable stubs, I am planning to just bury one of the larger tower sections in 4 feet of concrete and stack 2 sections above it.  I am also making my own top plate from 1/4 inch thick 6061-T6 and will use a GS-065 thrust bearing on top. The top section has a useable rotor plate about 56 inches down from the top.
