The pivoted tuning = shade lowered the pitch as it was closed. Now for you this can be an advantage = in its construction as you don't have to splice on any new wood extension or fill up a tuning slot. Instead of having to extend the pipe for a tuning stopper you will be making a tuning cap. Plug up the two holes in the = sides of the pipe where the wood screws held the tuning shade. Build yourself a =   small wooden 5 sided rectangular box that will just barely fit into the = open end of the pipe with leather packing around it. The open side of the box, =   side 6, is going to be facing downward toward the languid. This then = becomes a tuning cap of sorts only a tuning cap on the inside of the pipe instead = of the outside. Now you could put a tuning cap on the outside but you would have to worry about the spacing of the adjoining pipes allowing the cap to =   fit. I hope I have been clear enough so that you understand what I am proposing. I have used this method a couple of times with moderate = success. I say "moderate" because when the pipe plays an octave lower it is effectively a smaller scale so you lose some power. Opening the windgate will only help to a degree and I suspect the pipes you have may not have windgates but toe wedges for regulation. You will have to experiment a = bit but the outcome can be useable, especially if the pipes were large scale = to begin with.   Regards and good luck,   Al Sefl   p.s. A tuning handle on the top of the internal cap will make tuning = easier.
