I have assembled some pictures on how I shape my bottle lips, I have tried to make it as easy to understand as I could. I know a lot of guys don't use large bottles but the pictures and dimensions are for a 3 1/2 oz. bottle plug. I did this because the larger size makes it easier to work with when you first start out. Once you make one to your liking it is easy to scale everything down a little bit and make smaller ones. The plug is 7 5/16" long. The head at the top is 1 3/8" dia. measuring down from the top of the plug 1" it is 1 3/16" dia. Measuring down from the top of the plug 1 13/16" is the center of the neck at 11/16'' dia. The taper of the head is probably the most important part to get the lip to form nicely.
