In reply to doug5_10: Looks like you've done a bloody good job! I've never been sure about those pull up bars in the doorway though, i weigh 15.5 stone and think ill pull the whole doorway down, Hah!!!
In reply to doug5_10: Powerbar is rated to 20 stone, however they can't rate a 'sturdy' door frame as they state in the wee instruction leaflet. Despite being a pishy modern aluminium studded wall, this doorway is near a 4-way intersection so should be relatively OK. Cantilever action is pretty clever, haven't heard any horror stories of collapsing doorways! I've read about padding the contact points elsewhere too, although I've still got plenty of polyfila left from filling the holes left from discovering my non-existent studs!
Hopefully these give you some ideas. The idea was to allow it to be put away easily after finishing with it, which is where the metal tubes come in. They slide in and out allowing the board to be held up and then removed afterwards. I have some rough plans (not to scale) I created on powerpoint if you want a copy.
