Hi Dave
I bought a pack of these
Cutting Disks
I know they are maked for stainless but they cut through alloy like butter & made short work of my alloy sump chop
Finding them very durable on all metals & do not clog to badly with alloy like some of the slitting disks I have used in the past.
If you don't fancy using a grinder, a decent jigsaw should be more than able to cut the alloy.
Given a little diligence, quite a straight cut can be produced & can easily be fettled with a flap disk.
Take care using abrasives on alloy .... Decent eye protection is a must, Spent a miserable week once because of alloy particals in my eye .... Didn't care for that too much either
Dust mask too .... I am in the same boat as ASh & David, too late for me
