I've been given a Brambach Grand piano action to replace some parts in. The piano has been rebuild, and refinished, but the action still plays very heavy and loud. What makes this piano action alittle different is that it uses a patented action wippen and square knuckle designed by Brambach during the early/mid 20th century.
First thing you'll notice is the full-width jack pushing up against the square knuckle that is apart of the hammer body. This action still has the double entrapment like modern piano actions, but the geometry is abit different. These parts are no longer made, so in order to update this action, I'll have to replace everything with modern era parts. That's gonna change the actino geometry abit, but it shouldn't be a problem. I'll continue to post more pictures and my progress as things move along.

Notice the Drop button under the hammer rail. There is a Drop spoon that goes thru the jack (small window) and is attached to the rep lever. Since all modern parts have a drop pad on top of the rep lever and the drop screw is apart of the hammer flange, this hammer rail will need to be modified or made new.
