Ply-Split Braiding and related techniques require twisted or plied cord rather than braided cord.
Sadly, electric drill powered cord makers are hard to find since Bradshaw Machinery has not made new ones recently. You can write to Bradshaw directly at Bradshaw machinery bradshawmachinery@gmail.com They may resume making them if there is enough interest.
It is possible to make cords using a Lacis Cord Maker. This battery operated twister is not great for making many cords, but with some patience, it will do the job. Search on Google for suppliers or you can find it on Amazon.com
