Kick the hammer butt back off the jack top. I'd see if you can get it to regulate well before throwing it... you never know :) Cheers RicB "Patrick C.Poulson" wrote: <blockquote TYPE=CITE><style></style> Hello All: I have take in an upright with an unusual hammer butt, which is shown in the attached jpeg. It has a little lever coming from the back of the catcher, which catches the tip of the jack after letoff. It is actuated by a spring. I plan to replace the butts, unless there is some unknown reason for keeping these oddities. Anyone seen anything like this before? It is off of a 1885 Sohmer, a family heirloom.  Thanks, Patrick <pre WRAP> <hr WIDTH="90%" SIZE=4>_______________________________________________ pianotech list info: <a href="https://www.moypiano.com/resources/#archives">https://www.moypiano.com/resources/#archives</a></pre> </blockquote> -- Richard Brekne RPT, N.P.T.F.
