With the Henry milker, whether purchased or hand made, have a pressure gauge. I think it's recommended not to ever exceed 15psi. You should use just enough pressure to express milk.

There is a sphincter muscle at the base of the teat. The amount of pressure will actually depend on the individual goat. Like cows some are easier to milk then others. I have one that milks herself...not really, but her teat muscles are much looser and she will stream milk onto the ground when she lets down.

Here is a photo of a homemade henry milker. I pull this off the web last year when we were having trouble with one of the girls and thought we would need it, long story, but we didn't.

The photo is from a blog, I apologize, I can't find the original source. I remember the author said that she switch to a half pint bottle to get the desired psi.
