Hello!
I'm planning to hang a punching bag and a chin-up bar in the garage ceiling.
I built the garage 15 years ago and the rafters are spaced at approximately 120 cm if I remember correctly, with a lath and then plasterboard that is spackled and painted.
How would you go about fastening these items and finding the rafters without cutting up the entire ceiling?
Is it sufficient to attach to one rafter (even if you hit the middle, I think lateral forces might cause it to break and loosen since it is quite narrow?) or should I place a beam between two rafters?
Grateful for advice and tips!
