Norrie, what I don't like about your moulds is that there is a lot of extra metal at the head end, you will see what I mean in a second or two.
As the wire loops are INSIDE the mould it will be very difficult to make an exact fit for the wire. All moulds that I have seen are drilled so that the wire bend is outside the actual mould, this gives a bit of lee way for the final loops.
I use wire from a roll for some of my leads, I get it from a hard ware shop, 1.3mm, 50m for a couple of quid. It easy to bend and does not rust, the make that I can get is made by SUKI international, its a kind of fencing wire.
I would be tempted to ask Chris P to slightly re build the mould for you, if he agrees he can drill it out for you AND possibly give you a sample of how and where to get the exact size of wire that you will need.
Too thin a wire and you will have to either use blue tack to stop the lead running out of the mould and onto the wire giving sharp edges that would have to be cleaned off to protect your line.
A slow process to be sure.
I only sugest Chris because I have a great deal of respect for his engineering skills and he enjoys helping people.
It may also help you to do a search as this topic has been on here before.
There is a way of nearly mass producing the exact length and loop of the wire using a couple of nails (heads cut off) and a block of wood but thats another story
Cheers for now.
