I make my own balls for my flinters, .390 and .530...I use an old Coleman for a heat source and melt lead in a can...So I just had to buy a ladle and the molds...
To make sinkers for a Carolina rig here's what I do...Buy some small bass sinkers, heat shrink tubing and glass rattles...
I insert the bass sinker in the top of the tubing, insert the rattles and then 2-3 .390 balls in the bottom, take a lighter and shrink it all together..
You line goes through the hole in the sinker and this walks over rocks, plus rattles to attract bass....
