keyframe bedding

>> Hi Jon,
>>               Don't you just love refixing,  butcher jobs.  The easiest
>> fix is to get some 1/4" width iron on birch  edging material.  Good
>> cabinet suppy companies stock it.  Iron and Press it on real firm , so you
>> see some squeeze out.Just apply on the bad section.   Then roughly bed the
>> front rail. Now use a full length, so there is no seam.  This will give
>> you a low friction lip for fast pedal operation.
>> Bed front rail, then recheck the back rail, finally set the balance rail
>> gluide bolts.

>> PS Saw kerfing will not work so well with this type of problem
>> 
>> Hope this helps.

Jeff, Roger et all...
This subject is the topic of a mini-tech in Chicago.  Paul Dempsey is
teaching the class for the Institute.   These problems and more will be
covered in the fast paced 40 minute class.  Hope you all can be there, as
this sounds like a  problem encountered by many techs.
    See you in Chicago.
Joel
