That is looking good Dex and I like that the core has nicely chamfered edges. Is the core a "standard" part that you bought  ...  or did they wind it to your request?

I used 1.8mm wire and did wonder just how much harder 2mm would have been. I have used 2mm on some motor cycle coils many years ago and they were hard to wind being relatively small and fiddly  ...  but these big toroids are heavy enough to stay in place while we pull and stretch the wire around. I would not be afraid to try 2mm or maybe even 2.5mm.
