ROR retrofit - counter-lift design pic

ROR retrofit - counter-lift design pic

Pic of north wall during renovation of my 8x8 observatory (taken Sept 24, 2021) with roof partially rolled open a foot to expose the counter-lift. I’ve mounted 6-ft piece of 2x8 to inner face of rolling roof frame and using 6-ft pieces of 1-1/2” angle-iron to make interlocking connection for counter-lift (basic concept used by BYO but mounting on ‘inner face’). One piece of angle-iron is attached to 2x8 and other is to side of wall top-sill plate. Still need to add 1-1/2” out to gantry beam.
