Twisting big wires

Hello all!

So I have a unique project where I would have to Twist:

3x 6ga

4x 8ga

12x 10ga

has anyone experience with twisting big wire like this?

thank you and happy labor day!

You'll need lots of small filler wire to get a round cable (if that is your goal). Can you explain why you need to run the large gauge wires twisted?

We are trying something different at the boat company, this is behind the dash and there is a a lot of twists and turns

so rather then doing it in the boat we would like to make it a separate harness but still has to look really good.
