Hello List, Some months ago I posted on a 12 yr old Petrof Model 1 which I bought and have lent to a church for recitals etc. I have done a lot of normal routine work on the action (centers/key bushings/fine regulationetc.) and have improved the touch considerably and it is liked by pianists. However, as a pianist myself I know that the feel of the action is still not right and I intend working further towards bringing it to full potential. As soon as I have further access to it I shall bring the action home and, amongst other things, put a new set of Abels on it. Key weighting is very uneven also. One curious observation is that the action spread, which is 15mm, creates a situation where the drop screws are engaging at the tip of the leather pad on the wip balancier and not in the middle. I don't really see why this would affect the touch but I have not consciously seen a similar situation and it doesn't look right. I am wondering if a fundamental re think is needed on this action. If you think about it, to 'correct' this situation (new Model 1 has a 12.5mm action spread) it would mean that the wip rail would come backwards (towards the balance rail) to line up the drop screws and leather pads. BUT, this would throw out the capstan/lever heel relationship. What I am asking is, does this suggest the the capstans are in the wrong place to start with? In order to find the correct position of capstan on a key, can you actually work backwards from correctly positioning your standard Renner parts into their proper realationships (using wip rail positioning, jack angle etc) and then assume that the capstan position will automatically be right if it corresponds with the centre of the wippen heel. Would an acceptable 'magic line' be the result? ric -------------- next part -------------- An HTML attachment was scrubbed...
