I want to secure a "power rack" for weighlifting -- a square cage that supports a barbell so you don't need a spotter for squat and bench press. I'd like to fasten it to a wooden platform. My first thought was to bolt it to the platform, but the rack comes with no pre-drilled holes.
I haven't built the platform so I have some flexibility. Current plans: an 8' by 8' platform made of two layers of 5/8" OSB. That platform would rest directly on an old beat up concrete slab in my garage.
How would you connect/tie/bolt/whatever the frame to the floor?
