Avery, Yes i have some experience with this. you will have to be sure to use a very light hammer if using the 16.2mm knuckle. It is not only possible to use the 17mm knuckle, but necesary if the hammer is heavier than the original. vince - List, - - Anyone have experience choosing parts from the Renner Parts Kit - for an older Steinway 'M' (1925). Below is from Lloyd: - - >We recommend restoring all quality pianos, particularly of this - >vintage, to their original design, using original dimension parts. - >In the case of Steinway, this cannot be determined by the serial - >number due to the way those pianos were designed at crafted at - >that time. This is why we designed the Sample Parts Kit. Simply - >test the different shanks & flanges and wippens in the piano to - >determine the best fit. For example, your piano will have angled - >capstans, so one might assume the angled heel wippen to be the - >best choice. The capstan angles varied considerably at that time, - >and it's possible the straight heel will actually work better. - >You have three different shanks & flanges for Steinway and two - >basic wippen designs in your Kit. The 17.0mm shank was never used - >in the original Steinway pianos so you can rule that one out. - >Test all the others in the piano to determine the best combination. - - I have the kit but I need some advice on what, specifically, I - should be looking for, etc. to determine that "best fit". The piano - (or action) isn't in the shop yet but will be soon. Any advice - appreciated. - - An old dog trying to learn new tricks. - Avery - University of Houston
