I personally would not sand the braces down, this is one of the few areas where it's important to get a good tight fit.
i never said to turn it into sawdust.... but hes snapping ribs in half...
not to mention the epoxy will fill any voids made by sanding... but do what you like
100% iso alcohol has almoast no structural effect on epoxy...
Nobody said your method would not work or that he would make a pile of sawdust. Just seeking "strongest" solution to problem. Since he needs to remove the braces anyway, he may as well find the best answer. There are cases when your method would be the best one also.
If he had gone a little slower (learned with practice) he would have realized sooner the bind he was placing on the ribs and stopped before the damage
