Ballast Location and types

[ajmr2]

unfortunately, AJ's ballast stack was illegal as ballast must be retained by 2 or more 1/2in grade 5 or higher bolts in IT (9.1.3.D.9.l.2)

Actually, what you don't see is the fore/aft steel strap was bolted to the floor with 4 bolts and nuts, 2 on each end, which did meet the requirement. Believe me, I didn't want to see that thing come loose!
