OK
So here are the components of a milking machine.
First you have a vacuum pump. That is what gives you vaccuum. You can get a small vacuum pump cheap on ebay. I found one for $75 bucks that included a SS milking bucket in a local ad bulletin.
Next you connect the vacuum pump to a vacuum reserve tank. This is a tank that allows the system to build up vaccum and creates a cushion to prevent a lot of fluctuations that is hard on the teat end.
Mine is simply a captive air tank bought from Harbor Freight tools:

Then you will have to remove the fittings on the tank and install a vaccum gauge stall cock for you to hook your bucket to and vaccum pressure regulator.
The top one on this page will work for a small milker

Then you will need a long hose to connect to your bucket.
Finally you will need a bucket, a pulsator, milk line and inflations.
You can get a used bucket off of Ebay and set it up how you like.
I have a plastic bucket, it's the 65 lb poly one shown here

I can't remember where I bought it but I also have the Interpulse plastic lid shown here but you can buy a stainless lid too. I just wanted something light.

Then you need the pulsator
I have the L80

I like to use silicone milk line.
Then I like to use the silicone inflations.
I used to use a setup like the Silicone goat cluster shown here

Except for I had clear silicone hoses instead of black and I used a twin set of tubing from my pulsator so the inflations pulsed alternatively. The above cluster is set up where both pulse simultaneously.
Nowdays instead of using a plastic Y to split the line I use the vanguard claw. More expensive but the Y is perfectly fine.
Let me know any questions.
You can go cheaper with a used bucket I just really like to see how much a goat is giving and like the clear lines and bucket.
