Ernst Kap grand

[A E]

Ill second what Andre says, broken plates, ive crossed 4 so far, why... whats wrong with them?
There was an exception however, crossed an Ernst Kap that had a few hairline cracks here and there, and one of the struts was cracked half way thrue... heres where it gets rediculous.. the owner askedme id be willing to weld the crack shut ... again.. apparently according to her hubby someone has attempted before YEARS ago but she couldnt show me the exact spot.... Ideas?

In spite of the name 'Pantzer Platte', most of the Ernst Kaps piano's I've come across had broken iron frames.

Any large, heavy plate is sometimes referred to as "Panzer Platte" in German.  If it were cast out of a higher grade, more expensive steel, it would surely be designated "Stahl Platte", to set it apart from a  "Guss Platte" (cast iron plate).  So much for the language and terminology.

But who knows exactly what Kaps' plate were made of?  One definite answer would be the results of a lab test of a piece of the plate...

Perhaps Kaps used that term in connection with full piano plates as opposed to 3/4 plates?

It could also be that the frames were made of cast steel rather than cast iron.  About the turn of the century Broadwood's grand frames were of cast steel, including, I think, the frame for the barless grands.  Such a frame would, I think, be extremely tough and very expensive to produce compared with the usual grey iron casting.
