I have braided 1, so I'm far from an expert on the matter. I recommend that you tear down an old rope and go from there. That's the way I did it anyway. i also got on a coupla sites of pro bull rope makers. You can learn quite a bit just by looking at photos.
I made a set out of chute cord (I know, sacrilege) for a friend. they turned out fairly well, but they didnt feel right to me. My buddy deemed pleased though. Sent me a 4oo dollar bowie knife in trade, so there you go.
Grant's encyclopedia gives proportions for the white gas/ parafin mixture near the introduction. He says that its used for "sizing sleazy leather". He also advises to use caution as the vapors hug the ground and can travel a considerable distance. If anyone here has any experience with meth labs (from the busting side) they will advise you that Grant is correct. When those vapors go, they go big. Not trying to discourage anyone, just be very very careful.
