My Blackbird is on its way and I want to be able to hang in my bonus room above the garage. I've bought some big eye screws that are rated to 350lbs. My plan is to put these in the ceiling which I think are 2x6s. They run across the room. I plan on putting the screws into two different rafters to distribute the weight.
What I'd like advice on is how far apart to put the screws to get the proper angle and height off the floor. The ceiling is 8 feet and the room is almost 15 feet wide.
Thanks for any help.
