Pappy,
I've become really good at fixing arf's. My method for rebuilding has been to make sure I pick up all the peices. Real careful not getting fuel on peices as I pick up wreckage. I then go home and with some CA try to reconstruct what used to be. I then reinforce with wood and Epoxy to get strength. As little as possible though to save weight. I've torque rolled my AT-6 3 times. Air Speed Air Speed!!!!! Anyway the firewall wasn't straight anymore so I simply added some thin aircraft plywood to front of existing firewall to strengthen and straighten. Worked great. I've got rest of plane straight and it should be ready to fly this weekend. Hope this helps.
