I'll shortly need to cut a number of wall panels to length. These are a sandwich of lightly ribbed steel sheet (0.5 - 0.7mm) and a 70mm foam core. I'll have around 40metres of saw cut in total.
For the last, similar job, I used metal cutting discs in a small angle grinder, but it was a slow and painful process, and, as I couldn't get right through the thickness in one pass, difficult to align the cuts from both sides. It also got through discs at an alarming rate.
So I have an excuse for a new toy, but which? I have a small, elderly Metabo jig saw, that probably wouldn't be up to the job, and I don't think I've seen long enough blades for it. So do I go for a bigger jig saw, a reciprocating saw, or even a B&D Scorpion? I'll accept the argument, as put forward in the FAQ, that a good jig saw is a very different animal to a cheapo, but does the same apply to reciprocating saws? Let's assume that I'd also use such a device for a range of other jobs it could do better than a chain saw or a hand-held circular saw.
Can a cheap cordless (e.g.
Any other recommendations or experiences will be gratefully received.
Do all these reciprocating saws take each other's blades, or could one be stuck with the saw equivalent of Betamax?
