Hi Jim, I've got a couple of those cheap small ones where the ratchet has completely failed, that I've been intending to do exactly the same thing for quite a while now. But I am going to use brass, as I haven't got any copper the right size. The cheap ratchets are what they are, but they do have a decent knurl on them. Nice job you've made of yours.
Regards Nick.
Nick, I've made them before by using plumbers copper pipe (sometimes with copper end caps silver brazed on other without) and melting lead inside the copper pipe.
