Your Instruct-able is commendable. Nice job. I would like to caution everyone about using brass fittings in this design tho.All brass contains lead and lead compounds As a home brewer for the last 45 plus years. I know brass and alcohol should not mix if you don't want lead poisoning.Lead poisoning is a lot like arsenic poisoning and may take years to affect you or could kill within days or months.It depends on ones tolerance and exposure limits. Also avoid stainless steel valves that aren't rated for potable drinking water as they contain carcinogens that cause cancer. All of these things have a cumulative effect over time so my advice is that if you want to be healthy and live to be a ripe old age is to avoid these materials as much as possible.In closing I would like to recommend a plastic spigot (HDPE I believe) From any beer and wine home brew shop. They are safer,much cheaper and come with all the gaskets and nut necessary to install. If there is not a home brew shop near you they are readily available on line and are commonly used for the sparge bucket construction for all grain beer brewing.Please do not be offended or discouraged in any way by my comments,as I said you have done a great job of putting together this Instructable.
