Steinway used Dolge presses for many years and it's likely that the sheet sizes are the same size as from the early days in Dolgeville... I'll do a little digging into Steinway sheet size and let you know what I find. It would tell us a little more.... In the mean time I'll sign off for a few days by saying I don't want to argue about the goodness or badness of high, medium, or low zone hammer weights. It's safe to say that beautiful tone may be had from high, medium, or low zone hammer weights and bad tone may be had from high, medium, or low zone hammer weights and some rather average tone may be had from high, medium, or low zone hammer weights. It's a question of knowing and balancing all the variables. In defense of high zone hammer weights, there are countless examples of fine pianos with high zone hammer weights and I have data on a number of individual pianos with TopHigh hammer weights produced in the factory and they have amazingly beautiful sound. Fazioli and Steingraeber to name two. Your not going to convince pianists playing these pianos that they shouldn't be hearing such beautiful tone... The best part about this whole conversation is that we all are talking, thinking, and considering more about the quality of hammer felt, and the weight of hammers in regards to voicing. Special thanks to Andre (Antares in the Netherlands) for starting off the thread! I'm off to catch my train to Colorado... Regards and Cheers! David
