I'm getting ready to do the final welds on the base. Unfortunatel there
are no specific dimensions given in the paperwork.
The outside distance on the tower "ears" is 23". I'm using the raising
fixture to hold the base "ears" for building the rebar cage. When
bolted to the raising fixture the "inside" dimension between the ears is
23 1/4" That leaves an 1/8th of an inch space between the tower ears and
the base ears on each side , or 1/4" total.
I'm assuming I should space the base ears in from the raising fixture
with washers, to give no more than 1/32nd of an inch clearance so when
the bolts are tight the tower and base ears will mate flush and tight..
This should allow for a snug fit, but not interfere with raising the
tower and give face to face contact for a good holding force when the
bolts are tight ( snug plus 1/2 turn)
Comments?
