Who Here Makes Their Own Power Cables?

I got the ends from Parts Express and the cable from Lowes.  I used Carol Cable Extension Cord which UL approved.  During assembly I tried various size conductors: 10,12,14 and 16 awg.  I ended up with 12 awg for my amps 14 & 16 for everything else.  That took place years ago and all my gear has changed, some devices many times and never considered any cord changes.  I never considered wire that is not UL approved for purpose.

I have been using these Viborg connectors on my power cords.

Cable is secret sauce that I obtain from my employ as an industrial electrician, cant say any more.......

Send me one Uber! Or the wire....please.

I think your cables are a1+ Grannyring.
You don't need mine, I'm just lazy and can't  be bothered to twist them all together!
Stuff I use is maybe overkill and might not be for all tastes for sure.

@grannyring 
I bought some of that wire to try for power cords when it was released and forgot about it. You just reminded me of it. I'll give it a try. How many twists do you do (i.e. how many per inch or per foot)? Is it just slightly twisted, or as much as you can, or somewhere in the middle?
Thank you!
