You have to replace the valves in your heads or you'll burn them out with alcohol.
I make wine as a hobby, and used to have a still for making shine. Who doesn't in Pennsylvania?
Anyway, if you're not planning on drinking it just get a five gallon bucket, water, yeast, a lemon, 10 pounds of sugar, and a 1/2 can of corn meal. Bring a few gallons of water to boil and stir in the corn meal and a few pounds of sugar. Try to dissolve the sugar as much as you can. Boil that for a few minutes, then dump it into the bucket. Top up the bucket with cold water. When it cools to room temperature slice up the lemon and squeeze it in. Add two packets of baker's yeast (Red Star), and add the rest of the sugar. Stir it. Cover with a dish towel and let it sit to ferment for 10 days. Stir it once a day. You can find all these ingredients at the local supermarket for around $15. Use the cheap stuff.
Look on the net for plans on building a still. You're looking to build a reflux still, not a pot still. Build the reflux tower as high as you can to get a higher percentage of alcohol on the first run. It'll cost you between $50-$100 to build a good still, maybe less depending on what you already have on hand.
