RSJ vs Lintel on 2.6m External Wall/ Knock Through

[monkeysDIY]

No Good.....
I am going in alone...
The Catnic required has to have SWL 60.9Kn and have ordered CXC 50/100 3000m.
Quick question on propping up....
How many Acros (inside) & Strongboys (outside) would be recommended and any particualar distance apart?
Im guessing I sit on inside under scaffold board and joist and equi-distance within planned hole on outside?
