Here I show how the case was made and a view inside the windchests

frame for windchests The frame, or case takes shape. This frame will support the windchests that the pipes sit on and also allow about 24" under to access the windchests from below if a magnet sticks.
checking fit of windchests on frame Checking how the windchests will fit on the frame.
frame with oak sides installed Here is the same frame with oak side panels installed.
inside new windchests Inside one of the new windchests made by Nordlie organ builders. The magnets are made by Matters, Inc. Different size magnets are used depending on the size of the hole for the pipe.
front view of case A front view of the oak case unfinished.
putting finish on oak sides Oak sides have been removed to apply stain and lacquer finish. Organ builders use lacquer as opposed to polyurethane because the finish can be repaired easily if damaged.
case assembled in Luverne the case is installed in the basement ready for pipes
original windchests These are the original windchests. Figured now would be the best time to update them before pipes are installed on top. I replaced all the leather valves that attach to the magnets and cover the pipe holes.
replacing gaskets Old gasket material between the toeboard and the winchest frame was cork and there were some air leaks. Leather is preferable so I replaced the cork with leather. Columbia Organ Leathers cut the leather gaskets into strips for me. Otherwise they would send a skin(cowhide) and I would have to cut strips.
leather gaskets Just a close up of the leather gasket material
punching holes in leather Making holes in leather for screws. You can't just drive a screw through this thick leather you have to cut it first.
