cutting holes in an RSJ for cable runs. Anyone cracked this nut ?
I've done it using the drill lots of overlaping holes method; using a jisaw with metal blade on horizontal cut; and 4" angle grinder with carbarundum metal cutting disc (4 cutts).
the latest job needed 4 holes cutting so after spending so long lying on my belly nursing various overheating power tools I'm motivated to ask for ideas from others right now!
