hello bilt my still using plans from world class still internal reflux instead of using half inch copper for the reflux i used quarter inch od copper 5' coiled and made a 6" long coil in the top of the colum i use 2' copper mesh and 2' of marbles in the 2" collum. run the 15gl boiler at 200f with 13gl of 14% on propane, and top of collumn at 79c to 81c distilate is 88% to 87% i run in total reflux for first 30min then throw away first 250ml runs about 1 liter per hour till near the end then all the sudden it just starts barely dripping so i end the run and end up with about 12liters of 50% after diluting. run it through 3' of carbon in a 2" pvc pipe takes about 13hrs to filter taste great and if i add about 20 ml of glycerine per liter its real smooth. ive drank abour 5gl of the tuff taste the same if i distill once or twice is this goog or not
