Hi Jon
Assuming you have a standard 12" hacksaw, just stick 'em on the lugs of the handle and tighten it back up. You may have to squeeze the blades together to start the cut prettily, but once started they will behave themselves. You'll struggle if you're using a junior hacksaw of course. I've never bothered, but I think you can get blades of different thicknesses if needed.
By the bye, I shall be 68 next birthday and Derek Sheldon's "Riffler Files" have entirely passed me by. I'm starting to wonder what else I've missed out on!
