After seeing the cost (about $30) for a pre-made bottling bucket I looked around and found I can get the gate valve shown below from Amazon and Lowe’s sells food grade bucket and lid for about $7. So that makes it about half the price of a pre-built one. I just had to be careful to drill it up high enough off the bottom of the bucket so the nut on the inside of the bucket so it doesn’t hit the bottom of the bucket while tightening it. For an addition $9 I got a filter that fits right in the top of the bucket.
