Our hobby was started by guys who made their own gear and now few even attempt a very easy power cord build . Furukawa used to supply Oyaide OCC copper and when they stopped production Oyaide researched and now produces their own which is even better than the PCOCC from Furukawa . Here's my recipe for the best you can find and cheap for the quality:
You need shielded power cable and connectors for both ends here is the cable :
https://global.rakuten.com/en/store/chuya-online/item/92509/This is Oyaide's heaviest , a 10 gauge cable using their 102ssc copper( Google that) .This is the great supplier from whom I purchased .Their Ebay store has higher prices .
For connectors you don't want plated brass, find copper conductors and if plated , only gold or silver are acceptable unless you are trying to use the cable as a tone control device . Here are the U.L. approved plugs I would have used had I found them before the more expensive ones I did use ( which are slightly better in limited supply and I won't reveal ) :

No soldering. Wire cutters, strippers a phillips screwdriver are the tools you will need. You will be amazed at the results. Do your best to not nick the wires and definitely research how to assemble or get help . To get polarity correct, the wires go directly into the IEC plug ( and you Should do that end first). On the power plug end you will need to make the black and white wires exchange sides so black goes to Line ( marked L ) , making sure no strand of wire shorts to the other side. Get a friend to help/coach you and DO NOT attempt this if you don't yet understand . It's not that hard , but is lethal done incorrectly .
