<DIV><FONT face=Arial size=2> A word of caution on =
steaming/heating a warped key back into shape. I have found out the hard =
way
that steaming/heating a warped key in most cases will return the key to =
it's
original form, but after a few days it starts to twist right back to =
where it
was warped originally. Some wood just has a predisposition to be warped =
and the
only way to deal with it is to cut, shim and trim. Take into =
consideration that
the keytop will have to be replaced and the mortise also. A clear =
oversight of
side to side spacing should also be in mind. This key Sid is repairing =
is most
likely made of basswood which twists terribly compared to the good keys =
made of
sugar pine and spruce.</FONT></DIV>

<DIV><FONT face=Arial size=2>Sid Blum asked: "<FONT face="Times =

size=3>I'm working on a Baldwin Hamilton which has some badly =
twisted keys.
<BR>There are a couple of posts<BR>in the archives that mention =
straightening
by cutting kerfs in the <BR>keys and shimming, but not enough detail =
to give
me a clear picture <BR>of the procedure. Any advice much
appreciated.<BR><BR>Sid,</FONT></FONT></DIV>
<DIV><FONT face=Arial size=2><FONT face="Times New Roman" =
size=3>The methods,
I have employed, were either/and wetting and putting a reverse warp to =
straighten or steam. It's fairly easy to make a small steam box. The =
down side
to steam is that it's difficult not to unglue something that you want =
to stay
stuck.<G></FONT></FONT></DIV>
