Ok, thanks BierMuncher. I build up from RO so I spent an hour searching the web and found nada. Then I found a profile in Designing Great Beers, pg. 227. One interesting thing I found in that book is that it says Newcastle is 8 SRM. Yours looks good at 17 SRM.
Also, my roasted barley is...
28 lbs no problem. I've had the sparge water full to the top, then I'll drain some to the kettle as I add water from the top to run the last bit of the water through. I've double sparged on occasion as well.
I had a single that I made a double. I drilled a small tap hole and then used a step bit with a little oil and it worked like a charm. The chrome didn't even chip.
