ky jon,
I don't know how you do your math. I did two barrels last week with 8 gallons. At $0.79/gallon, that is like $3 a barrel. I'd have to do a lot of barrels. A whole lot of barrels. To make that pay.

If you were in the business of refinishing barrels you would use up a heck of a lot more 8 gallons. Then the investment of a few hundred dollars would be very reasonable. A basic system will make 4-5 gallons per day and cost less than $200.00. For $800.00 you could get unlimited amounts of distilled water. If you only do a few barrels a then you can afford to buy your water for a dollar a gallon all day long. SKB should be able to justify a few hundred dollars investment in equipment to do the quality work the he does. If not and he drops me a pm I buy it for him and take it out in trade.
