Hello
Is it safe to screw a chin-up bar into a load-bearing beam, presumably a laminated wood beam?
It should be attached with 7 M10 coach screws that are 80mm long.
Since I'm not completely sure of the dimensions of the load-bearing beam, I guess it's about 5000x240x115mm. However, the width of the opening is 220mm.
What I'm worried about is that the placement of the screws might weaken the load-bearing capacity, as they need to be screwed both high up and low down.
