Just an update. I let the boiler dry out and shook a lot of the dried up muck out. I'm thinking of pressure washing what I can and the let it soak in CLR, vinegar, or other cleaners for awhile. There is still hope for it, but it's still nasty. I wouldn't want to drink out of it yet.
Put together the optional coin mech and changer. I like this Stoner because of the change option. You can sell coffee or hot chocolate for 5,6,7,8,9, or 10c. I'm going to sell it for 9c. That's just too cool. The machine takes penies, nickles, dimes, or quarters for payment. Look at the coin mech on the left and the changer on the right. They are much simpler now.
