Hugh,
Just a comment on cutting metal (including cables [1]).
A hacksaw takes a long time and will be obvious to many people. I have found when needing to cut hardened steel or thick metal too big for bolt cutters to use a metal cutting wheel on a battery operated tool like the 18 V Dewalt Grinder. It is fast and effortless. It does throw alot of sparks, so beware of your environment and maybe throw a wet towel or blanket down. Also, the blades are fragile and can break if twisted, so keep some spares with your kit. – S.T.
