(back) Subject: combination action From: "Kelvin Smith" <KelvinSmith@untraveledroad.com> Date: Tue, 24 Oct 2000 16:10:24 -0600   Hello,   On Saturday I finished hooking up my combination action. It is an electro-pneumatic system with on and off pneumatics for each stop. I acquired a Windjammer blower which I am using for the air supply. I had a small regulator which I was going to use to reduce the pressure, but I found that the valves would operate under the static pressure. The regulator needed releathering so hoping to avoid the cost I tested it without it. It worked so I hooked the whole thing up. I confess that it is unable to move every stop, if I try to do that, but I haven't found any practical situations where it hasn't been able to move all the ones I needed. I spent about a week of my spare time wiring.   After that I winded my III mixture and finished wiring it yesterday. I = have tuned it up to the top octave and a few notes. Today I have been working = on finishing the wall around the blower to keep it from blowing cold air through the organ. That is done now except for a couple access panels.   I ordered a couple voicing tools yesterday so I can do something about taming some of my diapasons, including proportional dividers and a nicking tool. I need to raise some cutups. My room is very sympathetic to high frequencies and quite a bit less will be sufficient from some stops.   Kelvin Smith

If you really intend to tame the things, you = will want to start by adjusting (closing) windways and toeholes. Adding = nicking (esp if there is none) will also tend to tame the overall volume of a pipe somewhat, though it affects the tonality of it more. Do this cautiously, especially if the pipes are older and already nicked.   Hope this doesn't scare you too much...<G>   Regards,   Tim

I do not know you (or your capabilities), BUT... your reference to raising cut-ups really alarms me. Please only proceed with caution! Since most people on this list are using recycled pipes, the thought of raising the cut-up should only rarely come up .... only when placing pipe work on an exceptionally high pressure (if then). In most instances, you should be able to achieve the result you are looking for by adjusting the foot or flue. If this isn't the case, perhaps you should be swapping pipe work with someone who really needs to "lower" mouths. What wind pressure are you working with?... and what is a "Windjammer" blower?!!!   Hugh   >Hello, > >On Saturday I finished hooking up my combination action.
