OH, OK. I'm quite happy to have a go at that. I guess the material is just salvaged car springs from the wreckers? I've also been thinking that I can just turn the blades over for new edges. My biggest question may be the key ways in the spacers. If they are OK, and they do look OK, then it's new keys, better welding and replace or turn over the blades. I'll need to have the keys in my hand to check the keyways, so soon after Christmas I should be at that stage.
