Here is a time lapse of my setup for crushing my grains.
I use a Porkert Mill, a 5 gallon water jug (with the bottom cut out) and a Craftman 1/2″ drill all mounted on a 35 year old Black and Decker Workmate. This setup will crush 9-10Kg of grain in about 3 minutes. I have heard that some have issues with the crush coming out as flour with a porkert, but I have never had this issue. I use a plastic bag to guide the crush into my mash tun or bucket.
I would not recommend cutting the bottom off of the water jug but to only cut a hole from the bottom as the bottom rim of the water jug will keep the structural integrity of the jug.
The Workmate is used as a table for my mash tun also. Once the mash tun is not needed, it is used as a table to hold my beer. But I will be honest, I typically do not drink while brewing.
Other than the Workmate and the plastic bag (o.0), I have been using this equipment since I started all-grain brewing back in 2004. I am not big on spending a lot of money on my brewery, so I make do with what I have on hand. If memory serves me correctly, this setup did not cost any more than $30 (maybe less) thanks to yard sales and a Sears gift card.
