I aggree... not much we can do about = things right now... perhaps when the time comes we will have more to do then = we can handle...but for now pianos is about what is in front of me to do. <P>As for the Seiler. I decided on another straight forward job. I = will even out the new hammers weights so that there SW curve starts around 11,7 = grams and end at about 5,4. Looking at a SWR of around 6.0 and useing the = maximum FW's recommended by David. This will also mean a non whippen assist = spring configuration. <P>The main reason I want to do this is to gain a bit more practice at = approaching the job from this angle. Basically I am specifying a SW = curve for voicing concerns and BW for touchweight prefered by the instructor. = Using the maximum front weight table included in the Stannwood kit assures then = that the resulting SWR will be appropriate for the selected SW curve. <P>I think later on when I get liscensed and get a bit more experience = under my belt I will be able to decide on a lower FW table to reduce mass, = while otherwise still accomplishing what I want with regards to SWs. Tho I = think its going to be hard to avoid at some point using whippen assist springs. = I know a lot of you guys like them, and I dont dislike them... its just that I = want to first work without them for a while. <P>Hope this answers your question. Hammers are all bored, and I will = be starting the installation next week when the instructor is away for a = few days. <BR>  <BR>  <P>David Love wrote: <BLOCKQUOTE TYPE="CITE"> <STYLE></STYLE> <FONT size=-1>Richard:</FONT> <FONT size=-1>Even amidst all = this turmoil I feel the need to try and recapture some sense of = normalcy.  Tell me, what did you decide to do about the Seiler weight problem.</FONT> <FONT size=-1>David Love</FONT></BLOCKQUOTE> <P>-- <BR>Richard Brekne <BR>RPT, N.P.T.F. <BR>Bergen, Norway <BR><A href="mailto:rbrekne@broadpark.no">mailto:rbrekne@broadpark.no</A> = <BR>  </P></BLOCKQUOTE></BODY></HTML>
