Took me years to get mine built. That stiff wire is very difficult to handle, I can see why you ordered the welding cable. I just used some stiff 16mm wire for the chokes on my mppt and that was difficult enough. Wouldn't like to try 25mm.   Murphy's friend said   I now have inserted a permanent split PVC tube clamp  inside and a varnished rope wrap outside. This still allows good cooling while preventing wire  hum. I missed this point earlier Klaus  ...  are you saying that you did this INSTEAD of epoxying the windings  ...  or IN ADDITION TO? I used a split pvc tube inside the large Warpverter toroid and it worked well. Just kept filing the slot a few thou' at a time and try again, until it jammed in place. Nice and tight.
