well, i ended up using hte lag shield anchors.... but i went a size bigger, and added 1 of the ones i was originally going to use.....
what i did was slowly enlarged the hole, till it jsut barely fit in, then tapped it the rest of the way in with a hammer..... so it is tight..... once i had it all set, i tossed my daughter on the extended bracket..... she hung off of it, she weighs 95 pounds, soi figured the saftey margin was good, especially with it extended....
