That looks like the raw material for the original Penrose Kettle! There are quite a few kettles floating around St Louis that were cut down base units. We never did anything with the inners, that looks like a 40 liter. The outer makes a dang good Kettle.
Perry is made from straight pear juice. Watering it down will make a weak tasting low ABV beverage that won't age all that well. Grind the pears, let sit out overnight, juice the next day, ferment the juice. You will love the results.
Don't add water for heaven's sake. You want 100% juice. No need to boil either, just add a healthy batch of yeast. Not sure if a mere two pounds of maple syrup will add much flavor, but it won't hurt.
I believe that most of these companies are electropolishing. The nearest facility that can do ours is in Chicago. So far, we have chosen not to go that route.
I soak mine in Wally Worlds version of Oxyclean for a few hours while brewing. A splash of Starsan before filling is all I do. Have between 20 and 30 batches in mine, #2 prototype, have had no problems!

I had to drill and tap another hole in the bottom of the cylinder for a check...
Changed the fitting, and cut out the 90 bend in the tubing, looks better. Paint the framework tonight to match the Keezer, brew a 15 gallon batch of bitter tomorrow, can't wait to pour my first draw of cask ale at home!
The Brewhemoth combines the best of both in one unit. They are currently leak checked at 100 psi, built like a tank (heavier gauge metal than a keg), and relatively inexpensive.
When we started making these, I read everything I could find on the angle of cones. The only research on these was for dumping dry goods, the 60 degree cone was better at emptying a bin of corn or wheat over a shallower. Hence the huge abundance of 60 degree cones. The brewing industry adopted...
Devised a device to allow one to hook up the Brewhemoth to a ball lock gas in connector. Personally, I got tired of taking my ball lock fitting off my system every time I wanted to empty the Brewhemoth. So now we have a fitting that will clamp on the one inch triclamp on the top that will allow...
I'm afraid I was misunderstood, the coupler is welded with the inside threads (1/2 NPT) useable from the inside.. Set up to allow for a bazooka screen, dip tube, whatever to be screwed in.
Here is what I use.... http://www.harborfreight.com/1-4-quarter-hp-115-volt-submersible-water-pump-98342.html
Found that a glycol solution was a bit too thick for the cheaper pumps. Built a glycol chiller out of an old window AC and 30 quart cooler. Am able to chill an uninsulated Brewhemoth...
